  The known ratchet spanner has a bi-directional rotation function. However, when the user makes fine adjustments to the fixed parts, the fixed parts are tightened or loosened without fail, and adjusted to an appropriate tightening condition. The user must frequently change the direction of the ratchet spanner by switching the direction control block, and it takes time and effort to use the operation. Does not meet the vendor's usage requirements.

  The present invention provides a slide-type turning ratchet spanner, which has a first accommodating portion, a second accommodating portion, and a slide installing portion at one end of the drive portion, and a cut opening that communicates between the slide installing portion and the second accommodating portion. A main body having a step between the slide installation portion and the outer end of the driving portion; a ratchet rotatably provided in the first housing portion of the main body and having teeth on the outer periphery; two locking members Slidably provided at the two ends of the second housing portion of the main body, and has teeth on one side facing the ratchet of the two locking members, and a guide portion on the upper surface of the opposing ends of the two locking members The two locking members; a turning member, which is slidably installed on the slide installation portion of the main body, and has two guide portions of the two locking members at one end of the turning member. Is provided with a direction control unit corresponding to the Driving the direction control section is drawn from the cut of the ride installation portion to the second housing portion is a guide portion of the selective engaging member, the locking member is separated from the ratchet teeth.

  In the present invention, although the ratchet spanner described above has a bi-directional rotating function, it cannot be used as a fixed spanner, and when performing fine adjustment of tightening on a fixed part, the ratchet spanner is frequently switched to change the control member. This solves the problem of having to change the direction of rotation, which is time consuming and inconvenient in use.

A C-shaped snap ring 24 is provided between the concave groove 23 of the ratchet 20 and the concave groove 131 of the main body 10, whereby the ratchet 20 is coupled into the first accommodating portion 13 of the main body 10 and is in a relative rotational relationship with the main body 10. Can be generated.

  The two locking members 30 are slidably provided at two ends in the second accommodating portion 14 of the main body 10, and correspond to the teeth 22 on one side of the two locking members 30 facing the ratchet 20. A plurality of teeth 31 are provided, and a guide portion 32 and a recess 33 around the guide portion 32 are provided on the upper surface of the opposing ends of the two locking members 30, and the opposing ends of the two locking members 30 are provided. Each of the holes 34 is provided, and an elastic body 35 is provided between the holes 34, whereby the two locking members 30 are provided with elasticity.

  The turning member 40 is pivotally installed in the slide installation portion 15 of the main body 10 so as to be slidable in the horizontal direction, and in a direction corresponding to the two guide portions 32 of the two locking members 30 inside one end of the turning member 40. A control unit 41 is provided, and the direction control unit 41 protrudes from the cut 151 of the slide installation unit 15 and enters the second storage unit 14. A positioning hole 42 is provided at the other end of the turning member 40, and a first positioning recess 421, a second positioning recess 422, and a third positioning recess 423 are provided in the positioning hole 42. The positioning device 43 passes through the positioning hole 42 of the turning member 40 and is connected to the fixing hole 152 of the main body 10, whereby the turning member 40 is connected to the main body 10 and the cut 151 is closed. The positioning device 43 includes a fixing pin 431 and a positioning part 432, and the fixing pin 431 passes through the positioning part 432, the positioning hole 42 of the turning member 40 and the fixing hole 152 of the main body 10, and the positioning part 432 is the turning member. 40 is inserted into one of the positioning recesses, and thus the turning member 40 is positioned. In the first embodiment, the direction control unit 41 is a U-shaped groove having a narrow opening end and a wide closing end, and the positioning hole is a stepped hole.

  Please refer to FIG. The width of the direction control part 41 of the turning member 40 (ie, the distance between the two outer end angles) is the natural state of the two locking members 30 (ie, the state where the guide part 32 is not driven by the direction control part 41). ) Is slightly larger than the distance between the two guide portions 32 in FIG. At this time, the turning member 40 is located at the second operation position (intermediate position), and the positioning component 432 of the positioning device 43 is fitted into the second positioning recess 422 of the turning member 40 to control the direction of the turning member 40. The part 41 is located in the middle of the second housing part 14. The two outer end angles of the direction control part 41 of the turning member 40 enter the recesses 33 of the two locking members 30, and the two guide parts 32 of the two locking members 30 are both direction control parts 41. Therefore, the two locking members 30 abut against the wall surface of the second accommodating portion 14, and the teeth 31 of the two locking members 30 mesh with the teeth 22 of the ratchet 20, respectively. At this time, the ratchet 20 cannot form a relative rotational relationship with the main body 10, and the sliding-type turning ratchet spanner can rotate the fixed component in the forward and counterclockwise directions in the same manner as the fixed spanner.

  As shown in FIG. 6, when the turning member 40 is driven to reach the third operation position, the positioning component 432 of the positioning device 43 is fitted into the third positioning recess 423 of the turning member 40. The direction control part 41 of the turning member 40 drives the guide part 32 of the right locking member 30, and the teeth 31 of the right locking member 30 are thereby separated from the teeth 22 of the ratchet 20. The locking member 30 on the left side is not driven by the turning member 40 and abuts against the wall surface of the second housing portion 14. At this time, the ratchet spanner can turn the fixing component counterclockwise.

  Please refer to FIG. The turning member 40 is driven to be positioned at the first operation position, and the positioning component 432 of the positioning device 43 is fitted in the first positioning recess 421 of the turning member 40. The direction control part 41 of the turning member 40 drives the guide part 32 of the left locking member 30 to separate the teeth 31 of the left locking member 30 from the teeth 22 of the ratchet 20. The right locking member 30 is not driven by the turning member 40 and abuts against the wall surface of the second housing portion 14. At this time, the ratchet spanner can turn the fixing component clockwise. The turning member 40 is movable between at least three operating positions.

  The points to note are as follows. That is, the width of the direction control part 41 of the turning member 40 is larger than the distance between the two guide parts 32 in the natural state of the two locking members 30, whereby the turning member 40 is in the second operation position. At this time, the two guide portions 32 of the two locking members 30 are not driven by the direction control portion 41, and the slide-type turning ratchet spanner is used as a fixed spanner, and thus the practicality and convenience of the ratchet spanner are increased. Enhanced.

  FIG. 8 shows a second embodiment of the present invention, which is substantially the same as the first embodiment, but the difference is in the change in the form of the ratchet 20 '. The ratchet 20 ′ is provided with teeth 22 ′ and a concave groove 23 ′ on the outer periphery of the ratchet 20 ′, and a drive portion 21 ′ to which a sleeve (not shown) is coupled is provided at the other end of the ratchet 20 ′. A quick locking device 25 ′ is provided in the portion 21 ′, and the quick locking device 25 ′ can selectively limit the relative movement relationship between the sleeve and the driving portion 21 ′. A C-shaped snap ring 24 ′ is provided between the concave groove 23 ′ of the ratchet 20 ′ and the concave groove 131 of the main body 10, and the ratchet 20 ′ is rotatably coupled to the first accommodating portion 13 of the main body 10. In this embodiment, the drive 21 'is implemented as a square head.
