[0002] With the development of biotechnology, artificial insemination and embryo transfer technologies have been widely used in animal husbandry, especially in the livestock breeding industry. Compared with traditional natural insemination, artificial insemination can significantly improve the success rate of livestock insemination. For example, in pig breeding, artificial insemination in the pig's uterus can increase its chance of insemination and pregnancy and reduce breeding costs. Before artificial insemination of sows, auxiliary devices are usually required to fix the sows, as shown in the existing patent technology: After searching, the China Patent Network has disclosed a sow fertilization auxiliary device (public announcement number CN217091018U). During use, this type of device uses a fixing device to fix the sow's legs, which limits the sow's range of movement, effectively prevents estrus sows from hurting people, and facilitates the operation of artificial insemination.

[0003] However, there are still some shortcomings in the above-mentioned public patents and the sow insemination auxiliary devices adopted in the existing market: the existing method of using fixed parts to tie the legs of sows to limit their range of motion and facilitate artificial insemination, and the method of fixing the sow's limbs with leg ties, when the legs are tied, the sow is very likely to become irritable due to fright, resulting in inconvenience in the leg tying and fixing operation, and it is very easy to injure the staff, and the operation risk is high. To this end, the technicians in this field provide a sow insemination auxiliary device with a limit fixing function to solve the problems raised in the above-mentioned background technology.

Pedals 2 are symmetrically arranged on both sides of the frame of the pedal platform 1. The pedals 2 are conical platform structures. By arranging conical pedals 2 on both sides of the pedal platform 1, it is convenient for sows to get on and off the auxiliary device.

[0026] A first pair of clamping transmission mechanisms is arranged inside the frame of the pedaling platform 1, and the first pair of clamping transmission mechanisms include a first alignment screw rod 8 installed in the middle of the frame of the pedaling platform 1 and first alignment guide rods 7 symmetrically installed on both sides of the frame of the pedaling platform 1.

[0027] The first positioning screw rod 8 is bounded by the center line, and positive and negative threads that are compatible with the two groups of first positioning slides 9 are symmetrically arranged on both sides of the center line. When the first positioning screw rod 8 rotates, it utilizes the adaptive transmission of its positive and negative threads to push the two groups of first positioning slides 9 to slide symmetrically along the arm direction of the first positioning guide rod 7, and then pushes the two groups of clamping platforms 4 to move towards each other, thereby performing a preliminary clamping and fixing of the sow.
