In the present embodiment, the two connecting rods 10 of the two clamping arms 11 share one connecting bar 16, so that the connecting bar 16 can actually make the two clamping arms 11 perform synchronous movement during the movement process. When clamping the object, the connecting strip 16 is moved to make the two clamping arms 11 rotate closer, so that the clamping arms 11 can be closed to clamp the object. The middle of the connecting strip 16 is provided with a moving rod 6, the handle 1 is of a hollow structure, one end of the hollow structure is connected to the clamping main body 9, and one end of the moving rod 6 penetrates through the clamping main body 9 and extends into the handle 1 along the central line direction of the handle 1.
