[0022] Please see the appendix Figure 1-2 This utility model provides a movable yak restraint device, including an outer frame 1, a counterweight base 2, a body fixing device, a lifting device 3, and a rotating and lowering device. The counterweight base 2 has casters 4 below it. Between the counterweight base 2 and the casters 4, from top to bottom, are the lifting device 3 and a gravity detection device. The lifting device 3 can be used to lift the restrained yak or adapt the device to the yak's height. The gravity detection device can be used to weigh the yak. ​​The outer frame 1 is located above the counterweight base 2 and is used to fix the body fixing device and the rotating and lowering device. The body fixing device is used to secure the yak inside the outer frame 1.

[0023] Two rotating doors 5 are rotatably connected to the outer frame 1 at the front of the device. A circular opening is provided at the center of each rotating door 5 to accommodate the yak's head. The rotating doors 5, once connected, can secure the yak's head. A fixing ring 6 is also provided above the outer frame 1 to secure the reins, raising the yak's head and obscuring its vision.

[0024] The counterweight base 2 includes two sets: a left counterweight base 7 and a right counterweight base 8. Each set is equipped with two front and rear moving wheels 4. The counterweight base 2 has a U-shaped structure, and the left and right counterweight bases 2 are integrated at the front of the device. The counterweight base 2 is equipped with a counterweight block inside, which is used to support the rotation of the upper outer frame 1.

[0025] The left counterweight base 7 is connected to the bottom plate 9 of the outer frame 1. A fixing bolt is provided below the bottom plate 9 and inserted into the left counterweight base 7 for limiting its position. The rightmost edge of the right counterweight base 8 leaves a certain space towards the center, and the front and rear edges extend outward for setting up a rotating and tilting device. A rotating base 10 is fixed on the front and rear sides of the right counterweight base 8. A frame pivot 11 is provided at the lower right side of the outer frame 1, and the outer frame 1 is fixedly connected to the frame pivot bracket. The two ends of the frame pivot 11 are connected to the rotating base 10, so that the rotating base 10 is rotatably connected to the outer frame 1.

[0026] One end of the rotating inverting device is fixedly connected to the outer frame 1, and the other end is fixedly connected to the counterweight base 2, allowing the outer frame 1 to rotate relative to the counterweight base 2 via the rotating inverting device. A support rod is also rotatably connected to the right side of the outer frame 1, which can be inserted into the ground to support the outer frame 1 when it rotates to the right.

[0027] The rotating and inverting device includes two sets of rotating units, one at the front and one at the rear, respectively connected to the front and rear ends of the outer frame 1. Each rotating unit includes a first electric telescopic rod 12, a telescopic rod base 13, and a fixed connecting rod 14. The telescopic rod base 13 is fixed to the front and rear extensions of the right-side counterweight base 8. The fixed end of the first electric telescopic rod 12 is rotatably connected to the telescopic rod base 13, and its moving end is rotatably connected to the lower end of the fixed connecting rod 14. The upper end of the fixed connecting rod 14 is fixedly connected to the outer frame 1. The first electric telescopic rod 12 is electrically connected to a battery located inside the counterweight base 2. The extension and retraction of the moving end of the first electric telescopic rod 12 drives the fixed connecting rod 14 and the outer frame 1 to rotate along the rotating base 10.

[0028] The outer frame 1 is made of several intersecting columns welded together, with an outward-facing space at the lower center. The bottom plate 9 below is shaped like the counterweight base 2, forming a "U" shape, and includes two bottom plates on the left and right sides and a connecting plate in the middle. The two bottom plates 9 are welded to the left and right sides of the outer frame 1, and the connecting plate in the middle is welded to the lower front end of the outer frame 1. The left and right sides are welded to the two bottom plates 9 on the left and right sides respectively.

[0029] The body fixing device is mounted on the outer frame 1 and is used to fix the yak. ​​The body fixing device includes two sets of body clamping units, a moving unit connected to the body clamping units, and a leg fixing unit 15. One end of each body clamping unit is connected to the moving unit, and the other end clamps the yak's body. It includes a clamping plate 16, two upper and lower second electric telescopic rods 17, and a connecting plate 18. The fixed ends of the two upper and lower second electric telescopic rods 17 are fixedly connected to the connecting plate 18, and the moving ends are fixedly connected to the clamping plate 16. The connecting plate 18 is slidably connected to the outer frame 1. The second electric telescopic rods 17 are electrically connected to the battery inside the counterweight base 2. The extension and retraction of the moving ends of the second electric telescopic rods 17 drives the clamping plates 16 to move towards the center, thereby clamping the yak's body from both sides. The moving unit is used to adjust the clamping position of the body clamping unit. The leg fixing unit 15 is located at the lower opening of the outer frame 1 and includes four sets of binding straps for binding the yak's limbs.

[0030] The moving unit is disposed outside the outer frame 1 and connected to the connecting piece 18. The moving unit includes a support piece 19, a fixing block 20, a first connecting rod 21, a second connecting rod 22, a driving gear 23, a driven gear 24, and a power mechanism. The support piece 19 and the connecting piece 18 are respectively disposed outside and inside the outer frame 1, and are fixedly connected by a connecting rod that passes through the outer frame 1. The connecting rod can slide between the horizontal grooves formed by the two crossbars of the outer frame 1, thereby driving the support piece 19 and the connecting piece 18 to move back and forth. The fixing block 20 is fixed at the center position of the outer side of the support piece 19. One end of the first connecting rod 21 is rotatably connected to the fixing block 20, and the other end is rotatably connected to the driven gear 24. The driven gear 24 meshes with the driving gear 23 and is rotatably connected through the second connecting rod 22. One end of the shaft of the driving gear 23 is rotatably connected to the outer frame 1, and the other end is fixedly connected to the power mechanism. The power mechanism drives the drive gear 23 to rotate, thereby causing the driven gear 24 to rotate along the drive gear 23. Through the first connecting rod 21, the support plate 19 and the connecting plate 18 move along the horizontal slide groove of the outer frame 1, thereby moving the body clamping unit to a suitable clamping position.

[0031] The power mechanism includes a motor 25, a first sprocket 26, a second sprocket 27, and a chain, all fixed to the left and right sides of the outer frame 1. The output end of the motor 25 is fixedly connected to the first sprocket 26, and the first sprocket 26 and the second sprocket 27 are connected via chain drive. The second sprocket 27 is fixedly connected to the shaft of the drive gear 23. The motor 25 transmits power to the drive gear 23 via the chain drive of the first sprocket 26 and the second sprocket 27.

[0032] The lower part of the counterweight base 2 is also provided with feet 28 for supporting the device, which can be inserted into the ground for balancing the device.

[0033] In use, this invention is pushed forward from the rear of the yak, inserting it into the outer frame 1. The motor 25 is then activated, moving the two sets of body clamping units to suitable clamping positions. The second electric telescopic rod 17 extends to clamp the yak's body with the clamping plates 16. The operator can use the leg fixing unit 15 to secure the yak's limbs. After closing the rotating door 5, the yak's head is secured, and the reins are tied to the fixing ring 6, raising the yak's head to obscure its vision. The first electric telescopic rod 12 extends and retracts, rotating the outer frame 1 and the yak together along the rotating base 10, causing the yak to rotate 90°, thus allowing for various operations on the yak.
