After reaching the left end of the travel slot of the left car, the external equipment cuts off the product, the upper clamp moves upward under the action of the hydraulic clamp, and the lower clamp moves upward under the action of the hydraulic clamp. The pressure clamp moves downward under the action of the pressure clamp to release the product, and at the same time, the hinge parallel support angle is released, and the left car returns to the right under the action of hydraulic cylinder one; while the left car moves to the left and pulls, the right car moves to the right on the right car travel groove.

When the upper and lower clamping plates clamp the product, they are stretched to the longest stretching limit point and automatically limited, so that the upper and lower clamping plates keep consistent in every lifting data and clamping force of the product. Therefore, when clamping products on multiple lines, the force remains consistent without deviation, and the appearance of the multi-line products is kept from deformation, avoiding the occurrence of defective products and achieving high work efficiency. During the return stroke, the parallel support angles of the hinges are released at the same time, which will not affect the upper and lower clamping plates and the products.
