[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] First embodiment: See Figures 1-5 As shown, this utility model provides a sow mating support and fixing device, including a base frame 1, which adopts a layout of multiple frames arranged in a front-to-back sequence. The number can be flexibly adjusted according to the sow's body size, and can be three or four. Each base frame 1 adopts a "U" shape, which can provide ample standing space for the sow and form a preliminary limit on both sides of the body through the frame on both sides, effectively preventing the sow from moving left and right significantly. To ensure the stability of the overall structure, two adjacent base frames 1 are connected and fixed by a connecting rod 102. The connecting rod 102 connects the scattered base frames 1 into a whole, which significantly improves the load-bearing capacity and deformation resistance of the device. Each base frame 1 is paired with an upper limit frame 2, which is in the shape of an inverted "U" and corresponds vertically to the "U" shape of the base frame 1. The bottom end of the upper limit frame 2 is connected to the base frame 1 by a plug-in connection, so the height of the upper limit frame 2 can be flexibly adjusted according to the height of the sow. After being adjusted to a suitable height, it is fixed by bolts set on the side wall of the base frame 1. After the bolts are tightened, the relative position of the two can be firmly locked to prevent the upper limit frame 2 from loosening or shifting due to external force during mating. The inverted "U" shaped upper limit frame 2 and the base frame 1 together form an enclosing frame, which further restricts the sow's range of motion from the vertical direction and enhances the limiting effect. To achieve precise restraint of the sow's entire body, a ring frame 3 is installed on the foremost base frame 1. This ring frame 3 can stably restrict head movement, preventing the sow from trying to break free during mating by shaking her head, while also avoiding large head movements that would interfere with the mating operation. Meanwhile, a binding ring 4 is equipped on the farthest base frame 1. The binding ring 4 is specifically used to restrain the sow's tail. By moderately restricting tail movement, it reduces the interference of tail shaking on the mating operation, ensuring that the mating process is carried out in a stable posture. The main frame formed by the base frame 1 and the upper limit frame 2 achieves the limitation of the body on both sides and in the vertical direction. Combined with the head limitation of the front ring frame 3 and the tail limitation of the end binding ring 4, the entire device constructs a multi-dimensional support and fixation system, which fully ensures the safety and stability of sow mating operations.

[0020] Furthermore, the bottom of the base frame 1 is provided with a support block 101 for auxiliary support, and a crossbar 202 is connected between two adjacent upper limit frames 2, so that the height of all upper limit frames 2 can be adjusted when the upper limit frames 2 are lifted.

[0021] The second embodiment differs from the first embodiment in that: On the ring frame 3 of the sow mating restraint device, there is also a special protective cover 301, which can protect and limit the sow's head. The protective cover 301 has a frustum-shaped side wall structure. The frustum-shaped design not only retains a certain space for the sow's head to move, but also forms a gentle limit on the head through the inclined side wall, avoiding unnecessary pressure or injury to the sow due to rigid restraint. The protective cover 301 is made of leather. In terms of connection method, the small end of the protective cover 301 is connected to the ring frame 3, while the large end of the protective cover 301 extends towards the base frame 1. This connection design allows the protective cover 301 to be stably fixed on the ring frame 3, ensuring that it will not easily fall off or shift during the sow's movement. It also allows the protective cover 301 to match the natural posture of the sow's head facing the body. When the sow's head is inside the ring frame 3, the large end of the protective cover 301 can form a transitional protective area from the ring frame 3 to the base frame 1, further restricting the head from moving excessively in an unexpected direction. At the same time, it can also prevent the sow's head from directly colliding with other parts of the device to a certain extent, thus improving the safety and comfort of the sow's head during mating. The third embodiment differs from the first embodiment in that: The binding ring 4 is detachably connected to the upper limit frame 2 located at the end to ensure the stability and flexibility of limiting the sow's tail. The binding ring 4 is connected to the upper limit frame 2 at the end via a connecting strap 402. A fixing strap 401 is connected to the binding ring 4. The surface of the fixing strap 401 is provided with corresponding rough and barbed layers. In actual use, the position of the binding ring 4 corresponds to the position of the sow's vulva, so that the pig's tail passes through the middle of the binding ring 4. The rough and barbed layers fit together to quickly fix the binding ring. If you need to adjust the tightness or disassemble the binding ring, you only need to separate the rough and barbed layers. The operation is simple and convenient. The end of the connecting strap 402 corresponding to the base frame 1 is provided with an annular sleeve. The annular sleeve is a direct component for connecting the connecting strap 402 to the base frame 1. Its structure is adapted to the shape characteristics of the base frame 1 and can be stably fitted onto the base frame 1. The ring sleeve slides into the vertical side wall of the base frame 1. This sliding fit allows the connecting belt 402 to slide up and down along the vertical side wall of the base frame 1 to adjust its position as the sow's tail moves and as needed for mating operations. After sliding downwards, the pig can enter or exit the device. After sliding upwards, it works with the fixing strap 401 to limit the pig's tail. At the same time, the ring sleeve is located below the connecting rod 102. The connecting rod 102 indirectly limits the sliding range of the ring sleeve, preventing the ring sleeve from sliding excessively and detaching from the base frame 1. This ensures the stability and reliability of the connection between the connecting strap 402 and the base frame 1.

[0022] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
