The rotation member is rotatably disposed on the base and includes an inner barrel and an outer barrel coupled together. The movable plate has an outer surface and an opposite inner surface. The outer surface contacts at least a piston. The inner surface has a thread rod which is screwedly combined with the inner barrel along an axial direction of the rotation member. The direction switchable ratchet wrench is connected with the rotation member for driving the rotation member, such that the movable plate moves toward or away from the movable plate. When the movable plate moves away from the base, the at least a piston is pushed back into the piston bore.
