Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. In addition, the features of the embodiments and examples in the present application may be combined with each other without conflict.
The utility model relates to a typical embodiment provides a police uses manual injection apparatus, including the liquid pipe 1 that is used for placing the hot pepper water, the front end of liquid pipe is provided with shower nozzle 2. On the basis, the manual police manual injection device further comprises a gas pipe 3 and a gas cavity 4, the gas pipe 3 is arranged on two sides of the liquid pipe 1, the front end of the gas pipe 3 is open, a piston 11 is connected inside the gas pipe in a sliding mode, and a spring 5 is arranged between the piston 11 and the bottom of the gas pipe 3.
