Detailed Description

The principles and features of the present utility model are described below with reference to fig. 1 through 4, the examples being provided for illustration only and not for limitation of the scope of the utility model.

An injection device for harmless treatment of animals comprises an injection cylinder 1, a liquid suction cylinder 3, a mandrel 6, a positioning pin 7, a cap 9, a limit nut 10, a jacking nut 11, a spring 12, a first one-way valve 19 and a second one-way valve 5.

The mandrel 6 is reciprocally and slidingly connected in the injection tube 1, the injection tube 1 is provided with a first runner 2, and a sealing ring is arranged at the bottom of the mandrel 6 to ensure that the mandrel 6 and the injection tube 1 form a sealing cavity. The top of the injection tube 1 is connected with a first sleeve 8, the mandrel 6 is in a ladder shape, and the first sleeve 8 is used for limiting the highest sliding distance of the mandrel 6. The outer wall of the first sleeve 8 and the top of the injection tube 1 are provided with threads, the first sleeve 8 is fixed with the injection tube 1 through a cover cap 9, specifically, the cover cap 9 is provided with internal threads, and the cover cap 9 is respectively in threaded connection with the injection tube 1 and the first sleeve 8. The limit nut 10 is in threaded connection with the first sleeve 8, and the limit nut 10 is arranged above the cap 9; the jacking nut 11 is connected above the mandrel 6; the spring 12 is coaxially sleeved with the mandrel 6, and the spring 12 is arranged between the jacking nut 11 and the limit nut 10. Under the action of the spring 12, the spindle 6 has a tendency to withdraw outwards.
