At the same time, the thread directions of the second screw rod 3 and the first screw rod 21 are consistent. When the placing plate 29 rises to half the height of the support frame 12, the first spur gear 22 drives the four groups of second screw rods 3 to rotate in the opposite direction through the second spur gear 31, and the moving block 32 rotates on the surface of the second screw rod 3 and drives the connecting frame 33 and the positioning plate 34 to drop to a quarter of the height of the support frame 12. At this time, the positioning plate 34 is against the ground to prevent the fixing device from being offset and misaligned while supporting the device as a whole, thereby improving the stability during animal inspection and improving the accuracy and efficiency of animal inspection.

[0033] like Figure 1-9 As shown, the flip mechanism includes a fixed electric push rod 4, which is fixedly arranged on the outer wall of the placement plate 29. The output end of the electric push rod 4 is transmission-connected to a movable plate 41. A rectangular rack 42 is provided on the upper surface of the movable plate 41, and the movable plate 41 is slidingly connected to the outer wall of the placement plate 29. A driven wheel 43 is movably connected to the center of the outer wall of the placement plate 29, and the driven wheel 43 is meshed with the rectangular rack 42. The inner end of the driven wheel 43 is fixedly connected to a connecting rod 441, and the inner end of the connecting rod 441 is fixedly connected to a connecting shaft 44. The connecting shaft 44 is two sets and symmetrically fixed. Connected to the outer wall of the placement rack 45, initially, the driven wheel 43 is located on the leftmost or rightmost side of the rectangular rack, and the push-pull plate 54 is pulled from the outside. The push-pull plate 54 drives the card plate 51 to move outward through the guide rod 53 and compresses the reset spring 52, so that the card plate 51 is separated from the placement rack 45. Then the output end of the electric push rod 4 drives the movable plate 41 to move, and the movable plate 41 drives the driven wheel 43 to rotate back and forth 180 degrees through the rectangular rack 42, and the driven wheel 43 drives the placement rack 45 to turn over through the connecting rod 441 and the connecting shaft 44, so as to facilitate a comprehensive inspection of the animal.

[0034] like Figure 1-9As shown, the limiting mechanism includes a limiting groove 5 symmetrically opened on the inner wall of the placement plate 29, and a card plate 51 is slidably connected to the middle of the limiting groove 5. The outer side of the card plate 51 is fixedly connected to the inner wall of the placement plate 29 by a reset spring 52. Both sides of the outer surface of the placement plate 29 are movably connected with a guide rod 53, and the outer end of the guide rod 53 is fixedly connected to the push-pull plate 54, and the inner end of the guide rod 53 is fixedly connected to the outer side of the card plate 51. When the placement rack 45 is turned over, an outward lateral force will be applied to the card plate 51. When the two sides of the placement rack 45 are embedded in the interior of the card plate 51, the reset spring 52 resets and drives the card plate 51 to slide in the limiting groove 5 and fix the placement rack 45, thereby improving the stability of the animal turning over inspection and further improving the accuracy and efficiency of the animal inspection.

[0035] like Figure 1-9 As shown, the first moving mechanism includes a first bidirectional screw rod 451 symmetrically and movably connected to the inner wall of the placement rack 45, one end of the first bidirectional screw rod 451 is transmission-connected to a first knob 452, and a first opening 453 is provided on the upper surface of the placement rack 45 above the first knob 452, and the first bidirectional screw rod 451 is threadedly connected to the moving rod 454. When the first knob 452 is pushed, the first knob 452 drives the first bidirectional screw rod 451 to rotate, and the first bidirectional screw rod 451 drives the moving rod 454 to move toward each other to position animals of different lengths.

[0036] like Figure 1-9 As shown, the second moving mechanism includes a second bidirectional screw rod 46 symmetrically connected to the inner wall of the moving rod 454, one end of the second bidirectional screw rod 46 is transmission-connected to the second knob 461, and a second opening 462 is provided on the upper surface of the moving rod 454 above the second knob 461, and the second bidirectional screw rod 46 is threadedly connected to the fixing frame 6. When the second knob 461 is pushed, the second knob 461 drives the second bidirectional screw rod 46 to rotate, and the second bidirectional screw rod 46 drives the fixing frame 6 to move horizontally to fix animals of different widths.

[0037] like Figure 1-9 As shown, the positioning mechanism includes a fixing frame 6, the inner bottom wall of the fixing frame 6 is fixedly connected to a lower positioning block 61, a screw 62 is threadedly connected at the center of the upper surface of the fixing frame 6, and the end of the screw 62 is transmission-connected to an upper positioning block 63. By turning the screw 62, the screw 62 drives the upper positioning block 63 to move downward, and the animal's limbs are fixed between the lower positioning block 61 and the upper positioning block 63.

[0038] Working principle: When in use, first move the bottom support plate 1 to the designated area by moving the universal wheel 11, and adjust the placement plate 29 to the lowest position. At this time, place the animal in the inner cavity of the placement plate 29, and adjust the first moving mechanism and the second moving mechanism in real time according to the size of the animal. Push the first knob 452, the first knob 452 drives the first bidirectional screw rod 451 to rotate, and the first bidirectional screw rod 451 drives the moving rod 454 to move toward each other to position animals of different lengths. Push the second knob 461, the second knob 461 drives the second bidirectional screw rod 46 to rotate, and the second bidirectional screw rod 46 drives the fixing frame 6 to move horizontally to fix animals of different widths, thereby fixing animals of different sizes.

[0039] When fixing an animal, the animal's limbs are placed in the fixing frame 6, and the animal's limbs are placed on the upper surface of the lower positioning block 61. Then, the screw 62 is screwed, and the screw 62 drives the upper positioning block 63 to move downward, thereby fixing the animal's limbs for subsequent operations.

[0040] When inspecting animals, the output end of the lifting motor 2 drives the first rotating shaft 23, the first spur gear 22, the first screw rod 21 and the second rotating shaft 25 to rotate, and due to the use of the first transmission belt 24 and the second transmission belt 26, the four groups of first screw rods 21 are driven to rotate synchronously, thereby driving the placement plate 29 to be lifted for veterinary inspection. When the placement plate 29 rises to the height of half the support frame 12, the first spur gear 22 drives the four groups of second screw rods 3 to rotate in the opposite direction through the second spur gear 31, and the moving block 32 rotates on the surface of the second screw rod 3 and drives the connecting frame 33 and the positioning plate 34 to drop to the height of one-quarter of the support frame 12. At this time, the positioning plate 34 is in contact with the ground to prevent the fixing device from being offset and misaligned, while supporting the device as a whole, thereby improving the stability during animal inspection and improving the accuracy and efficiency of animal inspection.

[0041] When the animal is turned over for inspection, the push-pull plate 54 is pulled outward, and the push-pull plate 54 drives the card plate 51 to move outward through the guide rod 53 and compresses the reset spring 52, so that the card plate 51 is separated from the placement rack 45. Then the output end of the electric push rod 4 drives the movable plate 41 to move, and the movable plate 41 drives the driven wheel 43 to rotate back and forth 180 degrees through the rectangular rack 42, and the driven wheel 43 drives the placement rack 45 to turn over through the connecting rod 441 and the connecting shaft 44. When the placement rack 45 is turned over, it will apply an outward lateral force to the card plate 51. When the two sides of the placement rack 45 are embedded in the interior of the card plate 51, the reset spring 52 resets and drives the card plate 51 to slide in the limit slot 5 and fix the placement rack 45, thereby improving the stability of the animal turning inspection and further improving the accuracy and efficiency of the animal inspection. The overall structure is simple, the operation is convenient, and it is suitable for large-scale promotion.
