The bottom end of the support 11 is tightly pressed against the adjusting screw 5, and the end of the adjusting screw 5 is in contact with the end of the support 11. The position of the end of the support 11 in the groove of the sliding pliers head 1 can be adjusted by rotating the adjusting screw 5. The top of the support 11 is fixedly provided with a limit rod 22 by welding, and the limit rod 22 is slidably connected with a sliding hole 21. The sliding hole 21 is arranged on the surface of the movable handle 3. The outer side of the adjusting screw 5 is rotatably connected to the fixed handle 4, and the rear end surface of the adjusting screw 5 is provided with anti-slip patterns.
