[0023] A veterinary long-handled injection gun comprises a housing assembly 1, a pushing device 2 and a disinfection device 3. The housing assembly 1 comprises a liquid storage cylinder 101, the pushing device 2 is arranged inside the liquid storage cylinder 101, a circular cover 102 is arranged at one end of the liquid storage cylinder 101, a rubber plug 201 is movably arranged inside the liquid storage cylinder 101, a push rod 202 is arranged on one side of the rubber plug 201, the push rod 202 passes through the circular cover 102, an auxiliary block 203 is arranged at the other end of the push rod 202, the push rod 202 is movably arranged inside the liquid storage cylinder 101, and the push rod 202 is covered with an outer sleeve A first spring 204 is provided, one end of the first spring 204 is connected to the rubber stopper 201, and the other end of the first spring 204 is connected to the liquid storage cylinder 101. A fixing rod 205 is provided below one side of the rubber stopper 201, and seven limit blocks 206 are arranged in an array below the fixing rod 205. The seven limit blocks 206 are used for quantitative injection. A rectangular through hole is opened below the liquid storage cylinder 101, and a trigger 207 is movably provided inside the rectangle. Two second springs 208 are provided on the trigger 207, and the other ends of the two second springs 208 are fixedly connected to the lower end of the liquid storage cylinder 101.

[0024] The liquid storage cylinder 101 is used to store injection liquid. Before injection is required, the rubber stopper 201 is used to absorb the injection liquid into the liquid storage cylinder 101. In actual use, the needle 104 is first placed in the injection liquid, and then the push rod 202 is pulled toward the outside of the liquid storage cylinder 101. At this time, the auxiliary block 203 is used to pull the push rod 202 outward to save time and effort. The push rod 202 drives the rubber stopper 201 to move outward to extract liquid into the liquid storage cylinder 101. When the last of the seven limit blocks 206 below passes the trigger 207, the extraction is completed. When injection is required, the trigger 207 is pulled again. 7 slides downward out of the liquid storage cylinder 101, and the rubber plug 201 is pushed by the outward force of the first spring 204, and the rubber plug 201 is pushed toward the needle 104, and the injection liquid is discharged from the needle 104. While the rubber plug 201 is pushed toward the needle 104, the lower limit block 206 also moves toward the needle 104 at the same time. When quantitative injection is required, the trigger 207 can be gently pulled and then immediately released. At this time, the trigger 207 will return to the original position again by the force of the second spring 208. Through the buckle of multiple limit blocks 206, quantitative injection can be completed by controlling the trigger 207 when it is required.

[0025] Furthermore, the other end of the liquid storage cylinder 101 is fixedly connected to a conical cylinder 103 , one end of the conical cylinder 103 is connected to a needle 104 , and a fixed disk 301 is provided around the outer periphery of the conical cylinder 103 .

[0026] The conical cylinder 103 is used for connecting the transition liquid storage cylinder 101 and the needle 104 , and the fixing plate 301 is used for fixing the disinfection device 3 .

[0027] Furthermore, two circular through holes are formed on both sides of the fixed disk 301, and two telescopic rods 302 are movably arranged inside the circular through holes. A round block is provided at one end of the two telescopic rods 302, and the diameter of the round block is larger than the circular through hole. A third spring 303 is sleeved around the outer periphery of the two telescopic rods 302, and one end of the third spring 303 is connected to the fixed disk 301, and the other end of the two telescopic rods 302 is connected to a protective shell 304, and the other end of the third spring 303 is connected to a surface of the protective shell 304, and a leakage cabin 305 is provided inside the protective shell 304, and a cotton ball 306 is provided inside the leakage cabin 305, and the cotton ball 306 is sleeved around the outer periphery of the needle 104 for wiping the needle 104.

[0028] Among them, when it is necessary to inject the animal, when the needle 104 is inserted into the animal's skin, the animal's skin will push the protective shell 304 toward the fixed disk 301, and the protective shell 304 pushes the telescopic rod 302 toward the fixed disk 301 to move at the same time. The movement of the protective shell 304 will also drive the third spring 303 to squeeze. When the needle 104 is pulled out, the third spring 303 will drive the protective shell 304 to rebound toward the needle 104. In actual use, this operation can be used to prevent the needle 104 from being contaminated when not injected. A leakage cabin 305 is provided inside the protective shell 304, and the leakage cabin 305 is used to store disinfectant. A plurality of through holes are provided on one side of the leakage cabin 305, wherein the cotton ball 306 is close to the above-mentioned through hole, and this through hole is used to leak disinfectant into the cotton ball 306, wherein the cotton ball 306 is replaceable sterile cotton. When multiple animals are injected at the same time, they can be repeatedly disinfected by the above method, and the needle 104 can also be continuously disinfected during quantitative injection.

[0029] Furthermore, a square opening is opened above the protective shell 304, and a water filling neck 307 extends from the leakage compartment 305 to the top of the square opening. A rubber cover 308 is provided above the water filling neck 307, and a steel wire rope 309 is connected to one side of the rubber cover 308, and the other end of the steel wire rope 309 is fixed to one side of the water filling neck 307.

[0030] In actual use, the rubber cover 308 is pulled out, and disinfectant can be added to the inside of the leakage compartment 305 through the water injection neck 307. Through the connection points at both ends of the wire rope 309, the rubber cover 308 can be effectively prevented from being lost when the rubber cover 308 is pulled out.

[0031] Furthermore, a handle 105 is connected to the bottom of the liquid storage cylinder 101, a trigger window 106 is connected to one side of the handle 105, the top of the trigger window 106 is connected to the lower end of the liquid storage cylinder 101, the trigger 207 passes through the top of the trigger window 106, and the lower end of the trigger 207 is exposed in the middle of the trigger window 106.

[0032] The handle 105 is the gripping point during injection. The entire injection gun assembly can be picked up by holding the handle 105. When the trigger 207 needs to be pulled, the finger needs to be inserted into the trigger window 106. The trigger window 106 is used to prevent the trigger 207 from being accidentally touched and wasting the injection liquid.

[0033] To sum up, in actual use, first put the needle 104 into the injection liquid, and then pull the push rod 202 toward the outside of the liquid storage cylinder 101. At this time, the auxiliary block 203 is used to pull the push rod 202 outward to save time and effort. The push rod 202 drives the rubber stopper 201 to move outward to extract liquid into the liquid storage cylinder 101. When the last of the seven limit blocks 206 below passes the trigger 207, the extraction is completed. When injection is needed, the trigger 207 is pulled again, and the trigger 207 slides downward out of the liquid storage cylinder 101. The rubber stopper 201 is pushed toward the needle 104 by the outward popping force of the first spring 204. The injection liquid will be discharged from the needle 104. 01 is pushed toward the needle 104, and the lower limit block 206 also moves toward the needle 104. When the animal needs to be injected, the needle 104 needs to be inserted into the animal's skin. When the needle 104 is inserted into the animal's skin, the animal's skin will push the protective shell 304 toward the fixed disk 301. The protective shell 304 pushes toward the fixed disk 301 and drives the telescopic rod 302 to move at the same time. The movement of the protective shell 304 will also drive the third spring 303 to be squeezed. When the needle 104 is pulled out, the third spring 303 will drive the protective shell 304 to rebound toward the needle 104. The rubber cover 308 can be pulled off, and disinfectant can be added to the inside of the leakage cabin 305 through the water injection neck 307.
