When the bearing contact block is severely worn, it can be replaced simply, making the operation simple and cost-effective. The integral fixed gripper and integral movable gripper assembly plate are mounted on a linear guide rail. The swing of the lever is converted into the opening and closing of the integral fixed gripper and integral movable gripper assembly plate, thereby realizing the gripping and releasing of the welding strip.

[0050] Working principle:
