The present application acts through an auxiliary positioning device, and applies a rotational force to the adjusting button 411 according to the size of the worm, so that the screw 405 inside the adjusting groove 404 rotates, so that the moving block 406 drives the push rod 407 and the sliding block 408 to slide along the convex slide groove 410, so that the guide plate 409 moves to a suitable angle, so that the worm can quickly enter the operating range of the clamping block 403, thereby improving the efficiency of the worm holding and positioning operation.
