A U-shaped seat 6 is fixed, the top of the U-shaped seat 6 is threadedly connected with a stud 7, the top of the stud 7 is fixed with a knob 8, the bottom end of the stud 7 is rotatably connected to a carrier block 9 through a bearing, a splint 10 is fixed to the bottom of the carrier block 9, the splint 10 is located above the carrier plate 1, and the cross-sections of the carrier plate 1 and the splint 10 are both "V"-shaped structures, two guide rods 11 are fixed on the splint 10, the U-shaped seat 6 is provided with through holes adapted to the guide rods 11, and a limiting column 12 is fixed on the carrier plate 1.

[0023] The rabbit can be tied to the carrier plate 1 by using two sets of Velcro and two sets of fixing belts 3. The limiting column 12 can limit the position of the rabbit's head, and the rabbit's ears are placed under the clamping plate 10. Turning the knob 8 can drive the stud 7 to rotate, so that the stud 7 pushes the clamping plate 10 to move closer to the carrier plate 1, so that the rabbit's ears can be clamped and cannot be tilted or swung. In this way, with the help of the angle adjustment component, the rabbit's ears can quickly complete blood congestion after the rabbit's head is tilted downward, so as to complete the blood collection operation more quickly.

[0024] The angle adjustment assembly includes a bottom plate 13, a first U-shaped block 14 and a connecting block 15. The first U-shaped block 14 and the connecting block 15 are fixedly mounted on the carrier plate 1. A rectangular frame plate 16 is fixed to the upper surface of the bottom plate 13. A second U-shaped block 17 is fixed to the top of the rectangular frame plate 16. A carrier tube 18 is rotatably connected between the opposite inner walls of the second U-shaped block 17 through a pin shaft. The connecting block 15 is fixedly mounted on the carrier tube 18. A screw rod 19 is rotatably connected between the left and right inner walls of the rectangular frame plate 16 through a bearing. A slider 20 is threadedly connected to the screw rod 19, and the slider 20 slides with the inner wall of the rectangular frame plate 16. A third U-shaped block 21 is fixed to the top of the slider 20. A sleeve 22 is rotatably connected between the relative inner walls of the first U-shaped block 14 and the relative inner walls of the third U-shaped block 21 through a pin shaft. A connecting rod 23 is fixed between the two sleeves 22. A plurality of mounting holes 24 are opened on the bottom plate 13. A driving motor 25 is arranged on the left side of the rectangular frame plate 16, and the screw rod 19 is driven by the driving motor 25.

[0025] The driving motor 25 is used to drive the screw rod 19 to rotate, so that the screw rod 19 pulls the slider 20 to slide inside the rectangular frame plate 16 in a screw transmission manner. By adjusting the position of the slider 20, the angle between the connecting rod 23 and the rectangular frame plate 16 can be adjusted, thereby adjusting the angle between the carrier plate 1 and the bottom plate 13, thereby changing the angle at which the rabbit stands obliquely, and better meeting the requirement of congestion of the rabbit's ears.

[0026] How this utility works:

[0027] At the beginning, the carrier plate 1 is arranged parallel to the bottom plate 13, the rabbit is placed on the carrier plate 1, and the rabbit's head is against the limit column 12, and the rabbit is tied to the carrier plate 1 by using two sets of Velcro and two sets of fixing belts 3, so that the rabbit cannot move, the staff pulls up the two ears of the rabbit to make the two ears of the rabbit straight, and turns the knob 8 so that the knob 8 drives the stud 7 to rotate, and the stud 7 pushes the clamping plate 10 to move downward, so that the clamping plate 10 moves closer to the carrier plate 1, and under the mutual cooperation of the carrier plate 1 and the clamping plate 10, the rabbit's ears can be fixed on the carrier plate 1, so that the rabbit's ears cannot be tilted or moved;

[0028] The driving motor 25 is controlled to operate, so that the driving motor 25 drives the screw rod 19 to rotate. The screw rod 19 pulls the slider 20 to move toward the location of the driving motor 25 in a screw transmission manner. The slider 20 pushes the connecting rod 23, so that the angle between the connecting rod 23 and the bottom plate 13 continues to increase, so that the angle between the carrier plate 1 and the bottom plate 13 can continue to increase. At this time, the rabbit is in an oblique standing state. As the angle between the carrier plate 1 and the bottom plate 13 continues to increase, the blood filling speed of the rabbit's ears on the carrier plate 1 continues to accelerate until the blood filling is completed.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can 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 should be included in the protection scope of the present invention.
