The guide frame 41 is provided with a first slide hole 415, a second slide hole 416 and a receiving hole 417; the first slide hole 415 and the receiving hole 417 may be disposed on the upper fixing frame 411, and the receiving hole 417 is disposed along a radial direction of the first slide hole 415, and the second slide hole 416 may be disposed on the lower fixing frame 412; on the one hand, the volume of the upper fixing frame 411 or the lower fixing frame 412 can be reduced, on the other hand, through the modularized design, the processing can be respectively carried out, the mutual interference between the upper fixing frame and the lower fixing frame in the processing process is avoided, and therefore the processing difficulty is reduced. The first sliding hole 415 is slidably disposed on the cylindrical rod 43, the second sliding hole 416 is slidably disposed on the limiting rod 44, and the sliding limit fit between the first sliding hole 415 and the cylindrical rod 43 and the sliding limit fit between the second sliding hole 416 and the limiting rod 44 ensure that the guide frame 41 can only move along the axial direction of the rotating shaft 3, but cannot rotate. The upper end and the lower end of the left clamping plate 413 and the right clamping plate 414 are respectively provided with a first through hole 418, the cylindrical rod 43 can be abducted through the two first through holes 418 positioned above the left clamping plate 413 and the right clamping plate 414, and the limiting rod 44 can be abducted through the two first through holes 418 positioned below the left clamping plate 413 and the right clamping plate 414, so that the mutual interference between the arrangement of the left clamping plate 413 and the right clamping plate 414 and the cylindrical rod 43 and the limiting rod 44 is avoided; the first through hole 418 is preferably U-shaped (as shown in fig. 4), and by providing the elongated screw holes 410 in vertical arrangement on the left clamping plate 413 and the right clamping plate 414, it is possible to arrange the first through hole 418 in the U-shaped structure, the upper and lower holders 411 and 412 can be moved up and down with respect to the left and right clamping plates 413 and 414, so that the first slide hole 415 formed on the upper fixing frame 411 can be quickly positioned with the cylindrical rod 43, the second sliding hole 416 on the lower fixing frame 412 can be quickly positioned with the limiting rod 44, so that the sliding matching between the first sliding hole 415 and the cylindrical rod 43 and between the second sliding hole 416 and the limiting rod 44 can still be realized within a certain error range between the assembling size of the cylindrical rod 43 and the limiting rod 44 and the arrangement of the first sliding hole 415 and the second sliding hole 416, and the processing difficulty and the assembling difficulty of the two are greatly reduced; in addition, it is apparent that the first through hole 418 having a U-shaped structure can save more material cost.

Referring to fig. 4-5, the first wear-resistant bushing 48 is disposed between the first sliding hole 415 and the cylindrical rod 43, the first wear-resistant bushing 48 is mounted on the guide frame 41 in a limited manner, and the first wear-resistant bushing 48 is provided with a hole 481 corresponding to the receiving hole 417, so that interference on the mounting of the connecting block 421 and the guide block 42 is avoided through the hole 481. During installation, only by ensuring that the first wear-resistant shaft sleeve 48 cannot pass through the first through hole 418, the first wear-resistant shaft sleeve 48 can be directly limited under the clamping of the left clamping plate 413 and the right clamping plate 414 (i.e., the first wear-resistant shaft sleeve 48 does not need to be limited and fixed independently), so that the first wear-resistant shaft sleeve 48 is limited in the first sliding hole 415, and the first wear-resistant shaft sleeve 48 is ensured to be in contact with the cylindrical rod 43 all the time; the first wear-resistant shaft sleeve 48 can improve the sliding precision between the guide frame 41 and the cylindrical rod 43 and can prolong the service life of the guide frame 41 (i.e., the upper fixing frame 411); moreover, after abrasion occurs in the later period, the first wear-resistant shaft sleeve 48 can be independently replaced, so that the maintenance cost is reduced. The second wear-resistant bushing 49 is disposed between the second sliding hole 416 and the limiting rod 44, and the second wear-resistant bushing 49 is mounted on the guiding frame 41 in a limiting manner. During installation, only by ensuring that the second wear-resistant shaft sleeve 49 cannot pass through the first through hole 418, the second wear-resistant shaft sleeve 49 can be directly limited under the clamping of the left clamping plate 413 and the right clamping plate 414 (i.e. the second wear-resistant shaft sleeve 49 does not need to be limited and fixed independently), so that the second wear-resistant shaft sleeve 49 is limited in the second sliding hole 416, and the second wear-resistant shaft sleeve 49 is ensured to be in contact with the limiting rod 44 all the time; the second wear-resistant shaft sleeve 49 can improve the sliding precision between the guide frame 41 and the limiting rod 44 and can prolong the service life of the guide frame 41; moreover, after abrasion occurs in the later period, the second wear-resistant shaft sleeve 49 can be independently replaced, so that the maintenance cost is reduced. The first wear-resistant shaft sleeve 48 and the second wear-resistant shaft sleeve 49 can adopt self-lubricating bearings, and are good in self-lubricating property, wear-resistant performance, small in friction coefficient, long in service life, convenient to process, appropriate in elastoplasticity and capable of distributing stress on a wide contact surface, so that the bearing capacity of the bearing is improved.

Referring to fig. 5-7, the guide block 42 is a crescent-shaped structure, and a connection block 421 is disposed at one end of the guide block 42 away from the bidirectional screw groove 431 (i.e., the upper end of the guide block 42 in fig. 5); the connection block 421 is placed in the receiving hole 417, the outer side wall of the connection block 421 contacts the inner side wall of the receiving hole 417, the locking screw 45 is screwed to one end of the receiving hole 417 far from the first sliding hole 415, so that the separation of the guide block 42 from the bidirectional threaded groove 431 is limited, the guide block 42 is mounted on the upper fixing frame 411 (the guide frame 41), and the guide block 42 can slide along the bidirectional threaded groove 431 (under the action of the abdicating hole 481, the guide block 42 at the lower end of the connection block 421 can contact the bidirectional threaded groove 431; obviously, the abdicating hole 481 cannot interfere with the guide block 42 and the connection block 421, and therefore, the inner diameter of the abdicating hole 481 is greater than or equal to the inner diameter of the receiving hole 417). Since the guide frame 41 can move only in the axial direction of the rotating shaft 3, that is, the upper fixing frame 411 can move only in the axial direction of the cylindrical rod 43, when the cylindrical rod 43 rotates, the bidirectional screw groove 431 forces the guide block 42 to perform reciprocating sliding in the axial direction of the cylindrical rod 43, that is, the guide frame 41 performs reciprocating movement in the axial direction of the winding roll 2, so that the wire harness carried on the guide frame 41 can be uniformly arranged in the axial direction of the winding roll 2.

In order to improve the stability of the guide block 42 sliding in the bidirectional threaded groove 431, the receiving hole 417 and the connecting block 421 are both preferably circular structures, so that the connecting block 421 can be ensured to rotate in the receiving hole 417, and the adaptability between the guide block 42 and the bidirectional threaded groove 431 is improved, that is, while the guide block 42 slides in the bidirectional threaded groove 431, the orientation of the guide block 42 can be properly adjusted and changed according to the trend of the bidirectional threaded groove 431, so that the difficulty in assembling between the guide block 42 and the bidirectional threaded groove 431 is reduced. Otherwise, once the connection block 421 cannot rotate in the receiving hole 417, the guide block 42 is easily jammed during the sliding process in the bidirectional screw groove 431. In addition, the spring 46 is arranged between the locking screw 45 and the connecting block 421, and the connecting block 421 is displaced along the axial direction of the receiving hole 417 under the action of the spring 46, so that the guide block 42 can jump in the bidirectional threaded groove 431. Otherwise, once the locking screw 45 is installed too tightly, the friction force between the guide block 42 and the bidirectional threaded groove 431 is greatly increased, so that the difficulty of sliding the guide block 42 in the bidirectional threaded groove 431 is increased, and even the guide block is stuck in a serious situation; also, when the inner wall of the bidirectional screw groove 431 is not smooth due to machining errors, the guide block 42 is easily stuck without the action of the spring 46. In addition, in order to avoid the situation that the connecting block 421 cannot rotate due to over-tight contact between the spring 46 and the connecting block 421, a hemispherical structure accommodating groove 422 is formed in one end, far away from the guide block 42, of the connecting block 421, the ball 47 is arranged in the accommodating groove 422, and the upper end of the ball 47 is in contact with the spring 46, so that the spring 46 is supported, the contact between the spring 46 and the connecting block 421 is limited, the rotation between the ball 47 and the accommodating groove 422 can be realized, the friction coefficient between the ball 47 and the accommodating groove 422 is small, the transitional connection between the spring 46 and the connecting block 421 is realized through the ball 47, the connecting block 421 can be ensured to rotate freely in the accommodating hole 417, and the clamping phenomenon of the guide block 42 is effectively avoided; and the balls 47 and the springs 46 do not need to be fixed, so that the installation is convenient, and the smoothness of relative rotation between the connecting block 421 and the springs 46 can be further improved. Through the sliding fit between the receiving hole 417 of the circular structure and the connecting block 421 of the circular structure, and the spring 46 and the ball 47 which are arranged in a matching manner, the guide block 42 is prevented from being stuck in the bidirectional threaded groove 431, so that the stability of the guide block 42 sliding in the bidirectional threaded groove 431 is improved. The locking screw 45 is preferably a hexagon socket head screw (as shown in fig. 5, the external thread of the locking screw 45 is not shown in the drawing), and the structure is simple and the volume is small, so that the overall volume of the upper fixing frame 411 can be reduced.

Referring to fig. 3-4, the guide wheels 10 are at least one pair, and preferably two pairs; the guide wheel 10 is rotatably mounted on the guide frame 41, that is, the shaft of the guide wheel 10 can be fixedly mounted on the left clamping plate 413 and the right clamping plate 414 through screws; moreover, the elongated screw holes 410 arranged horizontally can be arranged on the left clamping plate 413 and the right clamping plate 414, so that the pair of guide wheels 10 can be arranged on the same vertical line, and the horizontal interval between the two pairs of guide wheels 10 can be adjusted. The outer annular surface of guide wheel 10 is coaxial to be equipped with annular structure's recess 101, and is formed with the centre gripping district between two recesses 101 on the same pair of guide wheel 10, can grasp the pencil through the centre gripping district to guarantee that guide frame 41 can be stable carry the pencil and remove. In addition, the connecting line between the two clamping areas is arranged along the radial direction of the winding roll 2, so that the wiring harness passing through the two clamping areas can be wound on the winding roll 2 more neatly.
