[0022] In this embodiment, as Figure 4As shown, the support assembly 9 includes a support column 19 vertically arranged on the upper side of the bottom plate 1. An oil-free bushing 20 is installed on the support column 19. A guide column 21 is slidably arranged in the oil-free bushing 20. A nylon support block 23 for supporting the front lower swing arm 26 is arranged on the upper part of the guide column 21. A spring 22 is arranged at the bottom of the guide column 21 inside the support column 19 for auxiliary support, improving the stability of supporting the front lower swing arm 26.

[0023] In this embodiment, as Figure 1 shown, a second bracket 24 is arranged on one side of the support column 19. A first photoelectric switch 28 is arranged on the side of the second bracket 24 to detect whether it is a left part or a right part of the product.

[0024] In this embodiment, as Figure 2 shown, a pressure head 16 is arranged on the upper side of the slide plate 17. A guide block 13 which is slidably matched with the slide plate 17 is arranged on the lower side of the slide plate 17.
