The two sliders located at the upper end both extend out of the chutes and are both fixedly connected with arc-shaped clamping blocks. The two sliders located at the lower end both extend out of the chutes and are both fixedly connected with annular blocks. On the inner walls of the two chutes, first racks are slidably connected.

[0006] One end outer walls of several of the sliders located inside the chutes are all fixedly connected with second racks, and several of the second racks are all meshed with the corresponding first racks. The upper end of the fixing block is fixedly connected with a fixing ring. A hole is penetrated through the middle position of the fixing block.

[0007] Preferably, screw holes are penetrated through the positions of the one side outer wall of the fixing block relative to the first racks. On the inner walls of the two screw holes, fixing screws are threadedly connected. One ends of the two fixing screws are both abutted against the corresponding first racks, and the other ends of the two fixing screws both extend out of the fixing block and are both fixedly connected with handles.

[0008] Preferably, one ends of the two first racks far from the second racks are both fixedly connected with springs, and the other ends of the two springs are both fixedly connected with the fixing block.

[0009] Preferably, a base is fixedly connected to the lower surface of the fixing block.

[0010] Preferably, a plurality of the sliders and the sliding grooves are both arranged in a T shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: insert the piglet into the fixing ring, use the annular block to fix the front limb of the piglet, unfold the front limb of the piglet to expose the vein of the piglet, move the arc-shaped clamping block inward to clamp and fix the waist of the piglet, so as to clamp and fix the front limb and the waist of the piglet, without the need for multiple people to fix the piglet, and prevent the piglet from shaking during blood collection, affecting the blood collection effect.
