Description

High performance pump

The invention relates to a high-efficiency air pump, in particular to a high-efficiency air pump capable of labor-saving and rapid gas injection into a tire body.

According to the bicycle, it is a popular sports equipment in the advanced countries in the world. It is also a very popular means of transportation. It has the advantages of environmental protection and light weight. Moreover, the types of bicycles vary greatly, and different frames have different sizes. Dimensions to meet the height requirements of different riders. Therefore, bicycle tires are also available in different sizes, which can be applied to different riding conditions or tires designed for special functional vehicles.

Due to the prevalence of riding bicycles, the accessories for bicycles have also developed rapidly. At present, there is a telescopic pump that is compact and easy to be fixed on bicycles, which is quite popular among users. The design of the pump that can be seen in the existing market, whether for the tires of the vehicle, the shock absorbers, etc., requires the use of an inflator for the action of filling the inflatable body.
