Description

Handle fixing structure of pedal pump

technical field

The invention relates to an air pump, in particular to a handle fixing structure of a pedal air pump.

Background technique

Referring to FIG. 9 , FIG. 9 is a perspective view of a conventional air pump 1 . The handle 2 of the existing pump 1 is not designed to be fixed, and only the hose 3 is in contact with and looped around the outer edge of the handle 2. It is not practical to use the handle 2 and the hose 3 to lock each other, because The design of the handle 2 itself does not have the function of clamping the hose 3. It is shaped like a smooth rod body. Therefore, when it is engaged with each other, the hose 3 will slide away from the two ends of the handle 2 as long as it is touched by a foreign object. And come off, can't limit handlebar 2 and make it fixed. And the handle 2 is easy to escape from the body of the pump 1 due to the action of the piston of the connecting rod. In carrying, the hose 3 is located on the outer edge of the handle 2. When the user holds the handle 2, he must hold it in a different The smooth handle 2 will increase the trouble of holding and cause inconvenience in carrying, and the design of wrapping around the outside of the handle 2 is also quite unsightly. Therefore, the commonly used fixing method of the handle 2 of the pump 1 There are quite a lot of shortcomings, so it is necessary to develop and improve.
