Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figure 1-3As shown, this utility model provides a technical solution: a veterinary auxiliary tool for dystocia in dairy cows, including a base 1 and a winch 2. The winch 2 is located at the rear of the base 1 and is rotatably connected to the side wall of the base 1 via a rotating shaft. A first drive gear 3 is fixedly connected to the right side of the winch 2, and a communication port 4 is opened on the left side of the winch 2. A support platform 5 is fixedly connected to the rear end of the base 1, and a hole is opened at the rear end of the support platform 5. A steel pipe 6 is fixedly connected to the outer side of the hole, and a limit rod 7 is fixedly connected to the inner wall of the rear end of the steel pipe 6 to prevent the steel wire rope 20 from excessively contracting and detaching from the steel pipe 6, thus avoiding the need to reconnect the steel wire rope 20 for subsequent use. A steel pipe 6 is inserted into the base 1. A drive shaft 8 is rotatably connected to the middle side wall of the base 1. A second drive gear 9 is fixedly connected to the drive shaft 8. The second drive gear 9 meshes with the first drive gear 3. The rotation of the drive shaft 8 realizes the function of rotating the winch through gear transmission. A first transmission gear 10 is set on the right side of the second drive gear 9 and is fixedly connected to the drive shaft 8. A brake shaft 11 is set in the middle of the base 1 and rotatably connected to its side wall. A second transmission gear 12 and a ratchet 13 are fixedly connected to the brake shaft 11. The second transmission gear meshes with the first transmission gear 10. The transmission gear drives the winch to rotate. The brake shaft 11 rotates synchronously. The ratchet 13 is located to the left of the second transmission gear 12. A control shaft 14 and a fixing rod 15 are provided at the rear of the base 1. The fixing rod 15 is fixedly connected to the side wall of the base 1 and is used to fix one end of the wire rope 20. The control shaft 14 is rotatably connected to the side wall of the base 1. A pawl 16 is fixedly connected to the right side of the control shaft 14. The pawl 16 engages with the ratchet 13 and can be firmly locked. A fastener 17 is fixedly connected to the left end of the control shaft 14. A base 18 is provided at the left end of the drive shaft 8. The bottom left side of the fastener 17 is provided with... A spring 19 is fixedly connected to the base 18. Under the tension of the spring 19, the fastener 17 pulls the control shaft 14 and the pawl 16 to firmly engage the ratchet 13, preventing the brake shaft 11 from rotating in the opposite direction, making it easier to use. A steel wire rope 20 is fixedly connected to the left side of the winch 2. The other end of the steel wire rope 20 is wrapped around the winch 2 through the connecting port 4, and passes through the steel pipe 6 from below the limit rod 7 and is fixedly connected to the fixing rod 11. This structure can prevent excessive rotation from causing the steel wire rope 20 to come off the steel pipe 6 and affect the next use. A rotating handle 21 is fixedly connected to the right end of the drive shaft 8 for rotating to drive the winch to rotate.

[0013] Furthermore, the base 1 has a handle 22 at the front end for easy fixing during use, and the fastener 17 has a protrusion at the rear left side for easy lifting of the fastener 17 to loosen the pawl 16 and allow it to rotate in the opposite direction. The spring 19 is a high-strength tension spring to ensure that the pawl 16 can be firmly engaged with the ratchet 13.

[0014] Furthermore, the steel pipe 6 is made of stainless steel, which is easy to clean and ensures safety and hygiene. The main body of the device is made of steel plate, which is sturdy and reliable. The steel wire rope 20 is made of high-strength, tough and tensile-resistant material.

[0015] In summary, the workflow of this utility model is as follows: Take out the device, disinfect and clean the steel pipe 6, lift the fastener 17, loosen the pawl 16, rotate the handle 21 to extend the wire rope 20 outward, insert the steel pipe 6 into the cow's birth canal, let the wire rope 20 fit into the fetus, then hold the handle 22 with one hand and rotate the handle 21 with the other hand to drive the winch 2 to rotate, tighten the wire rope 20 to dismember the fetus, rinse the device after use, and then tighten the wire rope 20.
