The lead screw is mounted on the movable pliers and can be rotated, but cannot be moved axially, and cooperates with the lead screw nut installed in the fixed pliers. When the screw is rotated by shaking the handle, the movable tong body can be moved axially relative to the fixed tong body to play a role of clamping or relaxing.

The fixed jaw body and the movable jaw body are each equipped with steel jaws and fixed with screws. The working surface of the jaw is made with a cross pattern, which makes it difficult for the workpiece to slip after clamping. The jaws are hardened by heat treatment and have good wear resistance.
