Slot 14, a rotating rod is rotatably set at the bottom end of the bottom plate 1, and symmetrically distributed support blocks are fixedly installed at the bottom end of the bottom plate 1. The rotating rod is rotatably installed between the two support blocks through a bearing. A gear 7 is fixedly sleeved on the outside of the rotating rod. The gear 7 passes through the strip groove 14 and the gear 7 is meshed with the rack 13. The two ends of the rotating rod are welded and fixedly connected with a U-shaped handle bar 3. The syringe is limited and fixed in the barrel 5, and the baffle 2 is attached to the outside of the animal body. The injection port is aligned with the injection site, the handle 4 is held by hand and then the U-shaped handle bar 3 is pressed to rotate the gear 7. The gear 7 acts on the rack 13, which can move the barrel 5 forward, and then the needle of the syringe passes through the injection port and pierces into the skin of the animal. This is labor-saving and convenient.

[0027] In the utility model, the sliding mechanism includes mounting blocks which are welded and fixed to both sides of the top of the base plate 1 and are symmetrically distributed. A fixing rod 9 is fixedly installed between the two mounting blocks by bolts. A symmetrically distributed fixing block 8 is fixedly installed on the outside of the cylinder 5 by bolts.

After the injection is completed, the U-shaped handle 3 is loosened. At this time, under the action of the spring 10, the cylinder 5 will move backward and reset, that is, the injection needle will automatically detach from the animal's body at this time, reducing the risk of needle bending.

[0029] In the utility model, the device for limiting the position of the syringe includes an end cap groove 6 which is symmetrically distributed and fixedly installed at one end of the barrel 5 by bolts. The end cap of the syringe can be just inserted into the end cap groove 6. A sealing plate 11 is inserted into the top of the end cap groove 6 through an opened slot. The sealing plate 11 can limit the end cap of the inserted syringe.

[0030] In the utility model, a magnetic block 12 corresponding to the sealing plate 11 is pasted and fixed to the bottom inner wall of the end cap groove 6. The sealing plate 11 is made of iron, which can limit the inserted sealing plate 11 and greatly improve the stability of the limit.

[0031] The working principle of the utility model is:

[0032] First, the veterinarian puts the syringe with the medicine into the barrel 5, and the end cap of the syringe can be just stuck into the end cap groove 6, and then the sealing plate 11 is inserted, so as to limit the syringe in the barrel 5. At this time, the needle of the syringe will not extend out of the injection port of the baffle 2. During the injection, the veterinarian holds the handle 4 to fit the baffle 2 of the booster outside the animal's body, aligns the injection port with the injection site, and then presses the U-shaped handle 3 to rotate the gear 7 on the rotating rod. The gear 7 acts on the rack 13 to move the barrel 5 forward, and then the needle of the syringe passes through the injection port and pierces the animal's skin. At this time, the other hand operates the syringe to perform the injection operation. After the injection is completed, release the U-shaped handle 3. At this time, under the action of the spring 10, the barrel 5 will move backward and reset, that is, the injection needle will automatically detach from the animal's body at this time, reducing the risk of bent needles.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
