Claims

[Scope of utility model registration request]

(1) A synthetic resin cylinder with a metal nut as the air outlet; a special double-ringed piston connected to a metal bar with a handle at the end; the inner ring of the special double-ringed piston has an air passageway. With an O-ring on the shaft or a short distance between the two rings, the O-ring is in close contact with the outer ring and the inner wall of the cylinder, creating a seal; a ball valve with a threaded end. Hollow ventilation needle; manual air bong configured with a spring that buffers the piston's retreating force! .

(2) The scope of the utility model registration claim is that the cylinder has a cylinder whose diameter at the air outlet end is slightly larger than the diameter at the air outlet end, and whose diameter gradually decreases from the air outlet end to the air outlet end. The manual air pump cylinder according to item 1.

(3) The manual as described in Paragraph 1 of the utility model registration claim that the metal nut (air outlet) of the cylinder has standard dimensions and can be replaced with and screwed onto other ventilation ball valve needles. Air pump cylinder outlet.
