[0003] The hand pull pump is also called inflator, inflator, inflator, inflator, and hand pull pump. It is a tool for inflating various inflatable objects (such as balls, tires, inflatable beds, etc.). During inflation, the user pulls up the handle, and air enters the piston below the inside of the hand pull pump. When the user presses down the handle, the air in the hand pull pump will be pushed into the air pipe by the piston, and the inflatable object can be inflated.

[0004] The current hand pull pump handle is generally an integrally injection molded handle structure. The handle is used for the user to hold and inflate the inflatable object by repeatedly pulling up and pressing down, and only has the function of the handle, which is relatively single.
