[0026] A bidirectional screw 2 is rotatably connected inside the connecting frame 1. Two screw blocks 3 are threadedly connected to the outside of the bidirectional screw 2. Clamping rings 4 are fixedly connected to one side of each screw block 3. Slide rods 5 are slidably connected to the outside of each clamping ring 4. One end of each slide rod 5 extends into the inside of the corresponding clamping ring 4 and is fixedly connected to a clamping block 6. First tooth grooves 8 are equidistantly formed on the outside of each slide rod 5. Two fixing rings 9 are fixedly connected to the outside of each clamping ring 4. Rotating shafts 10 are rotatably connected equidistantly between the corresponding two fixing rings 9. First gears 11 are fixedly connected to the outside of each rotating shaft 10. Each first gear 11 is meshed with the corresponding first tooth groove 8;

[0027] One end of each rotating shaft 10 penetrates through the corresponding fixing ring 9 and is fixedly connected to a second gear 16. U-shaped blocks 13 are fixedly connected to one side of each clamping ring 4. A rotating ring 14 is slidably connected between the corresponding U-shaped blocks 13. Second tooth grooves 15 are equidistantly formed on the outside of the rotating ring 14. Each second gear 16 is meshed with the corresponding second tooth groove 15.

[0028] Rotating cylinders 18 are rotatably connected inside each base 17. Moving blocks 19 are slidably connected inside each rotating cylinder 18. Threaded rods 22 are fixedly connected to the top of each moving block 19. Two slider blocks 20 are fixedly connected to the outside of each moving block 19. Two sliding grooves 21 are formed on the outside of each rotating cylinder 18. Each slider block 20 is slidably connected to the corresponding sliding groove 21. The top of each threaded rod 22 extends above the corresponding base 17 and is rotatably connected to a connecting block 25. The threaded rod 22 is threadedly connected to the corresponding base 17. Support columns 26 are fixedly connected to the top of each connecting block 25. The top of the support column 26 is fixedly connected to the connecting frame 1.

[0029] The inner walls of the base 17 are all rotatably connected with second bevel gears 24, and the outer sides of the rotating cylinders 18 are all fixedly connected with first bevel gears 23. The first bevel gears 23 are meshed and connected with the corresponding second bevel gears 24.

[0030] The outer side of the bidirectional screw 2 is fixedly connected with a fourth bevel gear 28. The inner wall of the connecting frame 1 is rotatably connected with a third bevel gear 27. The third bevel gear 27 is meshed and connected with the fourth bevel gear 28. The outer side of the connecting frame 1 is rotatably connected with a turntable 29. The output shaft of the turntable 29 is fixedly connected with the third bevel gear 27.

[0031] The outer sides of the bases 17 are all fixedly connected with servo motors 30. The output shafts of the servo motors 30 are fixedly connected with the second bevel gears 24. Both sides of the bases 17 are all fixedly connected with support blocks 31.

[0032] Silicone blocks 7 are fixedly connected to the sides of the clamping blocks 6 away from the sliding rods 5. Limit blocks 12 are fixedly connected to the ends of the sliding rods 5 away from the clamping rings 4.

[0033] Working principle:

[0034] When in use, when it is necessary to adjust the position of the restraint device to adapt to the patient's limb, rotate the turntable 29 on the outer side of the connecting frame 1. The output shaft of the turntable 29 is fixedly connected with the third bevel gear 27, so when the turntable 29 rotates, it will drive the third bevel gear 27 to rotate synchronously. The third bevel gear 27 is meshed with the fourth bevel gear 28 fixedly connected to the outer side of the bidirectional screw 2. Through the transmission of the bevel gears, the rotation of the turntable 29 is converted into the rotation of the bidirectional screw 2. Since two screw blocks 3 are threadedly connected to the outer side of the bidirectional screw 2 and the thread directions at both ends of the bidirectional screw 2 are opposite, when the bidirectional screw 2 rotates, the two screw blocks 3 will move towards or away from each other on its outer side. The screw blocks 3 are also fixedly connected with the clamping rings 4, thereby driving the clamping rings 4 to move and adjusting the distance between the two clamping rings 4.

[0035] When it is necessary to clamp the patient's limb, rotate the rotating ring 14. Second tooth grooves 15 are equidistantly arranged on the outer side of the rotating ring 14. The second tooth grooves 15 are meshed with the second gear 16. The second gear 16 is fixed at one end of the rotating shaft 10. When the rotating shaft 10 rotates, the first gear 11 fixed on its outer side also rotates accordingly. The first gear 11 is meshed with the first tooth groove 8 on the outer side of the sliding rod 5. In this way, the rotation of the rotating ring 14 is converted into the linear movement of the sliding rod 5 through gear transmission. The clamping blocks 6 fixedly connected to one end of the sliding rod 5 move inwards, place the patient's wrist or arm between the clamping blocks 6, and clamp it through the clamping blocks 6 to achieve the restraint of the patient.

[0036] Start the servo motor 30 outside the starting base 17. The output shaft of the servo motor 30 drives the second bevel gear 24 to rotate. The second bevel gear 24 meshes with the first bevel gear 23 outside the rotating cylinder 18, causing the rotating cylinder 18 to rotate. When the rotating cylinder 18 rotates, since the slider 20 outside the moving block 19 is slidably connected to the chute 21 outside the rotating cylinder 18, the rotation of the moving block 19 is restricted, so that the moving block 19 can only slide up and down within the rotating cylinder 18. The moving block 19 drives the threaded rod 22 to move up and down. The threaded rod 22 drives the support column 26 through the connecting block 25, thereby realizing the lifting of the connecting frame 1 and the restraint device. The meshing of the second bevel gear 24 and the first bevel gear 23 transmits the power of the servo motor 30 to the rotating cylinder 18, enabling the rotating cylinder 18 to rotate, and then driving the moving block 19 and the threaded rod 22 to move. Rotate the turntable 29, and the turntable 29 drives the third bevel gear 27 to rotate. The third bevel gear 27 meshes with the fourth bevel gear 28 to transmit the power to the bidirectional screw 2, causing the bidirectional screw 2 to rotate, and then driving the screw block 3 and the clamping ring 4 to move. The servo motor 30 serves as a power source, and its output shaft is fixedly connected to the second bevel gear 24, providing power for the lifting device, driving the second bevel gear 24 to rotate, and then driving the entire lifting mechanism to work. The support blocks 31 on both sides of the base 17 play a role in supporting and stabilizing the base 17. The silicone block 7 fixedly connected to the side of the clamping block 6 away from the sliding rod 5 contacts the patient's limb when clamping the patient's limb. The limit block 12 fixedly connected to the end of the sliding rod 5 away from the clamping ring 4 prevents the sliding rod 5 from sliding out of the clamping ring 4.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
