[0023] The needle 5 is inserted into the inner and outer walls of the first water outlet pipe 2 through the sleeve 3. After it is fixed, the pull rod 7 is pulled to drive the arc plate 8 to move upward, so that the needle tube 1 drives one end of the needle 5 through the limiting ring 6, so that the needle 5 passes through the first circular plate 11 and the second circular plate 14. When the needle 5 passes through the first circular plate 11, the second circular plate 14 is sleeved between the sleeve 3 and the outer wall of the first water outlet pipe 2, and the needle tube 1 cannot be inserted, so the pull rod 7 is released, so that the first spring 9 is compressed, thereby driving the arc plate 8 to move toward the outer wall of the needle tube 1, so that the needle tube 1 is fixed in the limiting ring 6, so that the needle 5 is inserted into the animal body, so that when the bottom end of the second circular plate 14 contacts the fur of the animal, after the staff continues to insert the needle 5 into the animal body, the second circular plate 14 drives the second circular shell 13 to move upward, thereby driving the second spring 15 to be compressed, so that the needle 5 is inserted into the animal body through the second circular plate 14 and the second circular shell 13. The needle 5 can be inserted into the animal's body better to prevent the animal's swing from causing the needle 5 to bend when the needle 5 is inserted into the animal's body with thicker fur, thereby reducing the damage to the animal's body. The pull rod 7 can also be pulled to push the limit plate, so that the limit plate drives the fixing plate 10 to move downward, so that the second circular plate 14 is at the bottom end of the needle 5, thereby loosening the pull rod 7 and fixing the needle tube 1 in the limit ring 6. When the first circular shell 12 enters the second circular shell 13, the depth of the needle 5 inserted into the animal's body can be controlled when drawing blood from a larger animal, preventing the needle 5 from being inserted shallowly and making it impossible to draw blood. When the blood drawing is completed, when the needle 5 is pulled out, the compression of the second spring 15 and the staff's pulling out of the needle tube 1 make it easy to quickly pull out the needle 5, so that the second circular shell 13 and the second circular plate 14 can better protect the needle 5 through the elastic force of the second spring 15 when the needle 5 is pulled out, preventing the animal from swinging when the needle 5 is pulled out, causing the needle 5 to bend and be difficult to pull out.
[0024] like Figure 4-6As shown, the interior of the sleeve 3 is fixedly connected with a first cylinder 16, and a through hole 17 is provided at the top and bottom of the first cylinder 16. A connecting column 18 is rotatably connected to one side of the surface of the first cylinder 16. One side of the connecting column 18 penetrates the sleeve 3 and extends to the outside of the sleeve 3, and the other side of the connecting column 18 penetrates the first cylinder 16 and extends to the inside of the first cylinder 16. The connecting column 18 extends to the side of the first cylinder 16 and is fixedly connected with a second cylinder 19. A cross hole 20 is provided on the second cylinder 19, and filter screens 21 are fixedly installed at the four ends of the cross hole 20. The cross holes 20 are mutually crossed inside the second cylinder 19. The blood enters the second water outlet pipe 4 through the needle 5, and then enters the sleeve 3. When the piston 22 continues to move, the blood passes through the through hole 17 and enters the second cylinder 19. The second cylinder 19 can be driven to rotate by the rotation of the connecting column 18. The cross holes 20 are provided on the outer wall of the second cylinder 19, and the filter screen 21 is fixedly installed on the inner wall of the cross hole 20, so that the impurities and the sucked hair can be better filtered in the sleeve 3, and the blood can pass through the cross hole 20 and then enter the needle tube 1 through the filter screen 21, so as to prevent the impurities and bacteria from being sucked into the needle tube 1 when drawing blood from animals with more hair, and thus cause detection errors when testing the animal blood.
[0025] like Figure 4 As shown, the inside of the needle tube 1 is slidably connected to a piston 22, a push rod 23 is fixedly installed on the side of the piston 22 away from the first water outlet pipe 2, and a push plate 24 is fixedly connected to the side of the push rod 23 away from the piston 22. By pulling the push plate 24, the push plate 24 drives the push rod 23 to move upward, thereby driving the piston 22 to move upward, so as to draw blood from the animal.
[0026] Working principle: When drawing blood from an animal, the sleeve 3 drives the needle 5 to be inserted into the inner and outer walls of the first water outlet pipe 2. After it is fixed, the pull rod 7 is pulled to drive the arc plate 8 to move upward, so that the needle tube 1 drives one end of the needle 5 through the limit ring 6, so that the needle 5 passes through the first circular plate 11 and the second circular plate 14. After the needle 5 passes through the first circular plate 11, the second circular plate 14 is sleeved between the sleeve 3 and the outer wall of the first water outlet pipe 2, and the needle tube 1 cannot be inserted, so the pull rod 7 is released, so that the first spring 9 is compressed, thereby driving the arc plate 8 to move toward the outer wall of the needle tube 1, thereby fixing the needle tube 1. In the limiting ring 6, the needle 5 is inserted into the animal body, so that when the bottom end of the second circular plate 14 contacts the animal's fur, the staff continues to insert the needle 5 into the animal body, so that the second circular plate 14 drives the second circular shell 13 to move upward, thereby driving the second spring 15 to be compressed, so that the needle 5 can better enter the animal body through the second circular plate 14 and the second circular shell 13, and prevent the animal from swinging and causing the needle 5 to bend when the needle 5 is inserted into the animal with thick fur, thereby reducing the damage to the animal's body, so that the pull rod 7 can also be pulled to push the limiting plate, so that the limiting plate drives the fixing plate 10 to move downward , so that the second circular plate 14 is at the bottom end of the needle 5, thereby loosening the pull rod 7, so that the arc plate 8 fixes the needle tube 1 in the limiting ring 6, and when the first circular shell 12 enters the second circular shell 13, it can control the depth of the needle 5 inserted into the animal's body when drawing blood from a larger animal, preventing the needle 5 from being inserted shallowly and unable to draw blood, thereby pulling the push plate 24, so that the push plate 24 drives the push rod 23 to move upward, thereby driving the piston 22 to move upward, so as to draw blood from the animal, so that the blood passes through the needle 5 into the second water outlet pipe 4, and then enters the sleeve 3, and when the piston 22 continues to move, the blood passes through the through hole 17, thereby entering the second cylinder 19, passing through the cross hole 20, and then entering the needle tube 1 through the filter screen 21, so as to prevent impurities and bacteria from being sucked into the needle tube 1 when drawing blood from animals with more hair, which may cause detection errors when testing the animal blood. After the blood drawing is completed, when the needle 5 is pulled out, the compression of the second spring 15 and the staff's pulling out of the needle tube 1 facilitate the quick pulling out of the needle 5, so that the second circular shell 13 and the second circular plate 14 can better protect the needle 5 through the elastic force of the second spring 15 when the needle 5 is pulled out, and prevent the animal from swinging when the needle 5 is pulled out, causing the needle 5 to bend and be difficult to pull out.
[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
