Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：
A kind of continuous injector for veterinary, including main needle tubing 1, second piston 26, and second piston are provided with main needle tubing 1
26 rear end is connected with catch bar 18, and the rear end of catch bar 18 is connected with installation projection 17, and installs the lower end connection of projection 17
There is pushing handle 19, be provided with back-moving spring 16 between installation projection 17 and main needle tubing 1, and the lower end of main needle tubing 1 is provided with lever
22, the front end of main needle tubing 1 is provided with installing pipe 4, and the front end of installing pipe 4 is provided with syringe needle 3, and first is provided with installing pipe 4
Check valve 2, and 2, the first check valve allows decoction to flow to syringe needle 3 by main needle tubing 1.
The upper end of main needle tubing 1 is provided with liquid storage pipe 11 by connecting tube 5, and the He of the first control valve 6 is provided with connecting tube 5
3rd check valve 23, the 3rd 23, check valve allow decoction to flow to main needle tubing 1 by liquid storage pipe 11, and the upper end of liquid storage pipe 11 is provided with
Feed tube 7 and air inlet pipe 9, and the second control valve 8 is provided with feed tube 7, the upper end of air inlet pipe 9 is provided with the second check valve
