Before the intermittent gear 2 704 disengages from the gear teeth of the hollow tooth plate 705, the punching needle 709 completes a downward and upward movement operation. Because the connecting cross plate 710 abuts against the upper surface of the strap placement seat 6, the punching needle 709 is prevented from taking the watch strap upward due to friction and other reasons, so that the punching needle 709 can stably punch a hole in the watch strap, thereby preventing the watch strap from being displaced and affecting subsequent use.

[0023] A positioning groove 13 and a positioning groove 2 14 are respectively provided on the upper surface of the feeding plate 407 and the upper surface of the base 1. The front and rear ends of the strap placement seat 6 are placed inside the positioning groove 2 14. The setting of the positioning groove 13 and the positioning groove 2 14 enables the strap placement seat 6 to be placed on the upper end of the base 1 through the positioning groove 2 14, so that the feeding plate 407 can intermittently move the strap placement seat 6 horizontally to the right by one grid through the positioning groove 13. The widths of the positioning groove 13 and the positioning groove 2 14 are slightly larger than the width of the strap placement seat 6, which increases the error of the feeding plate 407 in moving the strap placement seat 6, so that the strap placement seat 6 can be stably placed inside the positioning groove 2 14, avoiding friction with the side wall of the positioning groove 2 14 affecting the placement effect.

[0024] When the present invention is in use, the servo motor 2 is started, the servo motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the cam 401, the eccentric wheel 501 and the intermittent gear 1 701 to rotate, and the protruding end of the eccentric wheel 501 will first contact the inner wall of the lower end of the hollow lifting plate 502, thereby pushing the hollow lifting plate 502 to move downward, so that the hollow lifting plate 502 drives the push block 504 to move downward, and pushes the upper ends of the plug rod 1 505 and the plug rod 2 506 on its left and right sides out of the strap placement seat 6, so that the strap placement seat 6 loses its limiting effect; Then the cam 401 rotates to first drive the lifting seat 406 to move horizontally to the left. When the lifting seat 406 moves to the left to the leftmost end, the positioning groove 13 and the positioning groove 2 14 on the lifting seat 406 are in the same vertical plane. Then, when the lifting seat 406 moves upward, the strap placement seat 6 is inserted into the interior of the positioning groove 13, and at the same time, the strap placement seat 6 is driven to move to the top of the base 1, and then moves to the right to the rightmost end, so that the strap placement seat 6 moves one grid to the right, and a strap placement seat 6 on the left side of the punching assembly 7 is smoothly moved to the bottom of the punching assembly 7. At the same time, the strap placement seat 6 originally under the punching assembly 7 moves to the right to the right side of the punching assembly 7, completing one transfer of the strap placement seat 6. After the strap placement seat 6 moves one grid, the raised end of the eccentric wheel 501 no longer contacts the hollow lifting plate 502, and the tension spring 507 pulls the plugging rod 1 505 and the plugging rod 2 506, so that the plugging rod 1 505 and the plugging rod 2 506 are close to each other, and the push block 504 is pushed upward, and the plugging rod 1 505 and the plugging rod 2 506 are plugged into the plugging groove 16 of the strap placement seat 6, and the strap placement seat 6 is fixed in the interior of the positioning groove 2 14; Afterwards, the teeth of intermittent gear 1 701 rotate to mesh with spur gear 702, driving spur gear 702, rotating rod 703 and intermittent gear 2 704 to rotate. Intermittent gear 2 704 rotates to mesh with the teeth on the left inner wall of hollow tooth plate 705, driving hollow tooth plate 705 to move downward, so that hollow tooth plate 705 drives the rear lifting connecting rod 706, mounting frame 707 and connecting cross plate 710 to move downward. After the lower surface of connecting cross plate 710 contacts the upper surface of watch strap placement seat 6, the lifting cylinder 708 drives the punching needle 709 to move downward and then upward once. Before intermittent gear 2 704 disengages from the teeth of hollow tooth plate 705, the punching needle 709 completes a downward and upward movement operation, and then completes the punching work of a watch strap.
