5. The use method of the drill bit clamping mechanism with the double limiting function for the machine tool according to claim 1 comprises the following steps:
s1: the method comprises the steps that a central threaded rod (806) and a hollow threaded rod (811) are inserted into a central threaded groove (3) and an edge threaded groove (4) respectively, then the inserted rod (91) is pushed to enable one end of the inserted rod (91) to move to abut against the middle of the side face of a circular truncated cone-shaped pipe (93), the circular truncated cone-shaped pipe (93) moves downwards to drive a support spring (809) to slightly compress, the side face of a rubber block (94) is separated from the side faces of a first inner ring gear (803) and a second inner ring gear (804), then a user enables the first inner threaded pipe (801) to rotate clockwise to drive an edge bevel gear (813) to rotate clockwise, then the edge bevel gear (813) is driven to rotate clockwise by the edge bevel gear (813) to drive a central bevel gear (808) to rotate anticlockwise, threaded connection between the central threaded rod (806) and the central threaded groove (3) is achieved, the bottom face of the inner wall of the central threaded rod (806) and the bottom face of the inner wall of the central threaded groove (3) is abutted against the reserved threaded groove (811), threaded connection between the hollow threaded rod (811) and the edge threaded groove (4), the threaded groove (805) is achieved, when the hollow threaded rod (811) and the threaded groove (4) is connected, the first inner threaded block (2) is connected with the fixed block (805), and the first inner threaded block (801) again, and the fixed block (805);
s2: when the hollow threaded rod (811) is in threaded connection with the edge thread groove (4), the hollow threaded rod (811) drives the external threaded pipe (112) to move up and down on the side surface of the spline rod (111) when rotating;
s3: when the bottom surface of the central threaded rod (806) is abutted against the bottom surface of the inner wall of the central threaded groove (3), then the inserted rod (91) is pushed continuously, so that the inserted rod (91) is butted against the side surface of the circular truncated cone-shaped pipe (93), so that the circular truncated cone-shaped tube (93) moves downwards to drive the supporting spring (809) to continue compressing, and separates the center bevel gear (808) from the edge bevel gear (813), then the user rotates the rotating pipe (802) to make the rotating pipe (802) and the second inner ring gear (804) match with the edge bevel gear (813) on the upper side to drive the hollow threaded rod (811) to rotate, so that the hollow threaded rod (811) drives the external threaded pipe (112) to move downwards on the side surface of the spline rod (111) continuously when rotating, so that the external threaded pipe (112) moves downwards to press the octagonal rod (6), so that one end of the octagonal rod (6) is inserted into the clamping groove (810), carry out the spacing fixed of secondary to draw-in groove (810), then loosen the lasting power of applying to inserted bar (91), impel inserted bar (91) to drive the side of rubber block (94) and the inboard conflict and spacing of the inboard of first inner ring gear (803), second inner ring gear (804), make central bevel gear (808) and marginal bevel gear (813) joint under the effect of support spring (809) reset force this moment, accomplish the fixed of lathe main part (10) to drill bit main part (1).
