[0021] With reference to the drawings and in terms of embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0022] The insemination gun with movable sleeve comprises a movable sleeve 1, a handle 2 and a gun barrel 3. A fixed hole 4 is arranged in the handle 2, and the fixed hole 4 is used for connecting and fixing the movable sleeve 1. In order to fix the movable sleeve 1, an O-ring 5 is arranged on the inner wall of the fixed hole 4. In order to prevent the O-ring 5 from moving, an installation limiting groove 6 is arranged on the inner wall of the fixed hole 4, and the O-ring 5 is located in the installation limiting groove 6. The movable sleeve 1 is inserted into the fixed hole 4 of the handle 2, and the movable sleeve 1 is clamped and fixed with the O-ring 5. Corresponding to the O-ring 5, a positioning annular groove 7 is arranged on the outer wall of both ends of the movable sleeve 1. When one end of the movable sleeve 1 is inserted into the fixed hole 4, the O-ring 5 is just embedded in the positioning annular groove 7 after the movable sleeve 1 is inserted into position.

[0023] The opening inner diameters of both ends of the movable sleeve 1 are 2.5 mm and 3 mm respectively, and the two sizes correspond to small and large frozen semen tubes respectively. When the small frozen semen tube is installed, one end with the opening inner diameter of 3 mm is inserted into the fixed hole 4 for fixed connection; when the large frozen semen tube is installed, one end with the opening inner diameter of 2.5 mm is inserted into the fixed hole 4 for fixed connection.

[0024] In order to fix the insemination tube, a fixed section 8 and a hand-holding section 9 are arranged on the outer wall of the handle 2. The outer diameter of the fixed section 8 gradually increases from front to back, the insemination tube is installed on the movable sleeve 2 from front to back, the rear end of the insemination tube is clamped and fixed with the fixed section 8, and the clamping ring 10 of the fixed section 8 is clamped from the outside of the insemination tube, thereby completing the installation of the insemination tube. In order to improve the clamping effect, a plurality of anti-skid threads 11 with gradually increasing diameters are arranged on the outer wall of the fixed section 8, and the inner wall of the insemination tube can clamp the anti-skid threads 11.

[0025] In order to facilitate holding, two hand-holding discs 12 are arranged at the hand-holding section 9, and an anti-skid mesh 13 is arranged at the outer edge position of the hand-holding disc 9. The tail of the gun barrel 3 is provided with a hand pusher 14, and the outer edge position of the hand pusher 14 is provided with an anti-skid mesh 13. When the hand pusher 14 abuts against the handle 2, the front end head position of the gun barrel 3 just protrudes from the head of the movable sleeve 1 by about 3-5 mm, and just pushes out the frozen semen tube located at the head of the insemination tube.

[0026] In use of the device, first determine the diameter specification of the used frozen sperm tube. After determining the diameter specification of the frozen sperm tube, adjust the installation direction of the movable sleeve 1. When installing the small frozen sperm tube, one end of the 3mm opening inner diameter is inserted into the fixing hole 4 for fixed connection; when installing the large frozen sperm tube, one end of the 2.5mm opening inner diameter is inserted into the fixing hole 4 for fixed connection. Take the insemination tube and put it into the movable sleeve 1, after the insemination tube is installed in place, take the clasp 10 to fix the insemination tube. Finally push the gun barrel 3 to push out the frozen sperm tube at the head of the insemination tube.

[0027] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
