Abstract: A suction and dispensing tool (1) comprises: a cylinder (10) storing the fluid; a nozzle (20); a piston moving forward and backward in the cylinder (10); a piston rod (40) for driving the piston; and two ratchet type driving mechanisms (60) for driving the piston rod (40) forward and backward. The driving mechanism (60) comprises: a frame (50) having a handle (52), mounted to the cylinder (10), and two triggers (80) rotatably attached to the frame (50) at the front and rear sides of the handle (52). By rotating each of the triggers (80) to the handle (52), the piston rod (40) can be moved forward or backward. The rotating operation of the trigger (80) requires power smaller than an operation for directly pushing and drawing the piston rod by hand. Accordingly, it becomes possible to refill and dispense a high viscosity oil easily.

Abstract: The disassembling tool (30) is constructed such that the grip 55b of the arm 55 is inclined relative to the fixed portion 55a and the bottom portion 53 downward to the base 31 at an angle ?1 (about 45° to 55°). Therefore, the vertical component Fv of the force F, which is force for pushing down the arm 55, may become larger and the horizontal component Fh of the force F may become smaller. And, the disassembling tool is prevented from slipping on the working bench S, causing easy and smooth disassembling work.
