Clamp

Abstract

The present invention provides a clamp, comprising a first clamp body and a second clamp body. The first clamp body comprises a first clamp jaw and a first handle, movably connected to each other. The first clamp jaw is rotatably connected to the second clamp body at a first connecting position, and the first handle is rotatably connected to the second clamp body at a second connecting position. When the relative position of the first clamp jaw and the first handle is changed, a force occurs between the first clamp jaw and the first handle. A moment formed by the force with the first connecting position as a fulcrum is greater than a moment formed by the force with the second connecting position as a fulcrum. The present invention adapts two lever systems, such that equivalent force arms in actual use are increased without changing the tool size, achieving the purpose of labor-saving. The present invention further provides a water pump clamp having the abovementioned labor-saving structure, capable of quickly adjusting an opening width between the clamp jaws.
