Abstract

An air pressure buffer stick comprises: an outer tube 20 defining an inner moving space 22; a shaft 30; a connecting element 40 including first and second shoulder portions 41, 42; and a piston 50, the piston including a ring portion 51, a groove 52, a ring protrusion 53, a skirt portion54 and an air tank 56. With the structure design of the respective elements, the air-pressure buffer stick also includes an air discharging channel 55, so that when the shaft is pushed, it can avoid the occurrence of excessive pressure which can adversely affect the movement of the shaft besides producing a better buffer effect, achieving the objective that the shaft can be smoothly moved by a single pushing.
