The movement of the extrusion cylinder 307 drives the distance adjustment plate 303 and the strip movable plate 304 to move vertically upward. When the height of the upper surface of the strip movable plate 304 plus the thickness of the strip fixed plate 305 minus the thickness of the splint 1 and the splint 2 is obtained, the locking bolt is stopped when the product will not be broken and the product can be positioned. After the locking bolt 308 is driven by the T-shaped movable block 306 and the locking bolt 308 is turned clockwise, the locking block 309 is driven by the locking bolt 308 to enter the corresponding locking hole, and the force applied to the T-shaped movable block 306 and the locking bolt 308 is removed. At this time, the adjustment of the distance limiting mechanism 3 is completed. After the adjustment of the distance limiting mechanisms 3 on both sides of the splint 1 is completed, the splint 2 can be covered on the splint 1 and the clamping and positioning of the product can be completed through the connecting parts, which effectively prevents the product from being clamped off and ensures the production cost.
