Among them, the first motor 9 on the position driving assembly 6 drives the rotation of the rotating rod 10. Since the convex blocks 31 are circumferentially distributed and fixedly installed on the rotating rod 10, and the aperture of the opening on the sliding seat 12 is adapted to the convex blocks 31, it is convenient to rotate the rotating rod 10 and also convenient for the subsequent movement of the sliding seat 12. Since the first bevel gear 32 is fixedly installed on the rotating rod 10, and the second bevel gear 33 is engaged with the side end of the first bevel gear 32, when the rotating rod 10 rotates, the first threaded rod 11 on the first bevel gear 32 rotates, thereby realizing the left and right adjustment of the position of the threaded block 18 on the first threaded rod 11.
