[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0023] Reference Figures 1-3 An orthopedic external frame includes a U-shaped frame 1 with an adjustable clamping assembly inside. A C-shaped frame 4 is bolted to one outer wall of the U-shaped frame 1, and a guide rail 17 is bolted to one inner wall of the C-shaped frame 4. The guide rail 17 has multiple insertion holes 18 inside. A movable frame 19 is slidably connected to the outer side of the guide rail 17, guiding the movable frame 19 for stable movement. A second sliding groove 21 is provided inside the movable frame 19, and a round rod 22 is slidably connected inside the second sliding groove 21. The round rod 22 passes through the movable frame 19 and is inserted into the corresponding insertion hole 18. A spring 20 is sleeved on the outer side of the round rod 22, and the two ends of the spring 20... The telescopic frame 5 is fixed to the top of the movable frame 19 and the round rod 22 respectively. The top of the movable frame 19 is fixed with bolts. The top of the telescopic frame 5 is equipped with an adjustable suspension assembly. When the position of the telescopic frame 5 needs to be moved, the medical staff pulls the round rod 22 to move it along the second slide 21 until it is separated from the insertion hole 18 and the spring 20 contracts. At this time, the movable frame 19 is unrestricted. Then, the telescopic frame 5 is pushed to move the movable frame 19 along the guide rail 17 to the required position. Then the round rod 22 is released and the spring 20 rebounds and extends, so that the round rod 22 is inserted into the corresponding insertion hole 18, thereby adjusting and fixing the position of the telescopic frame 5 and the suspension assembly as a whole.

[0024] In this utility model, it should be noted that the suspension assembly includes a fixed frame 6, which is fixed to the fixed rod of the telescopic frame 5 by bolts. A take-up roller 15 is rotatably connected inside the fixed frame 6, and a rope 12 is wound around the outside of the take-up roller 15. Multiple threaded holes 14 are provided on one side of the take-up roller 15. A first screw 13 is inserted into one side of the fixed frame 6, and the first screw 13 is threadedly connected to its corresponding threaded hole 14. Through the cooperation of the first screw 13 and the threaded hole 14, the position of the take-up roller 15 is fixed, preventing rotation of the adjusted take-up roller 15. A crossbar 7 is fixed to the extended end of the telescopic frame 5 by bolts. A first groove 8 is provided at one end of the crossbar 7. A first slide 9 is slidably connected within the first groove 8. Pushing the first slide 9 moves it along the first groove 8, thereby adjusting the horizontal position of the hanging ring at the bottom of the rope 12 on the crossbar 7, making the device more versatile. A first guide wheel 10 is rotatably connected inside the first slide 9. One end of the rope 12 passes through the first guide wheel 10 and is connected to the hanging ring. When the patient's affected limb is put into the hanging ring, and when it is necessary to lift the patient's affected limb, the first screw 13 is turned to move it out of the thread hole 14, and then the take-up roller 15 is turned to wind up the rope 12, thereby raising the height of the hanging ring. The angle is adjustable, making it easier for medical staff to lift the patient's affected limb with less effort. The other end of the crossbar 7 is rotatably connected to a second guide wheel 11, and the rope 12 passes around the second guide wheel 11. The first guide wheel 10 and the second guide wheel 11 can guide the rope 12, allowing it to move in the desired direction. The clamping assembly includes a clamp 2, which is located inside the U-shaped frame 1. A lead screw 3 is threaded to the top of the U-shaped frame 1, and the lead screw 3 is rotatably connected to the clamp 2. Rotating the lead screw 3 causes the clamp 2 to move downwards, thereby clamping the support plate of the external device between the U-shaped frame 1 and the clamp 2, thus enabling stable installation of the device. The movable frame 19... Multiple rollers 16 are rotatably connected to both sides of the frame 19, and the rollers 16 are in contact with the inner wall of the C-shaped frame 4. The rollers 16 enable the movable frame 19 to move smoothly along the C-shaped frame 4. Two guide rods are fixed to the bottom of the clamp 2 by bolts, and the guide rods are slidably connected to the U-shaped frame 1. The guide rods can guide the clamp 2 so that it can move up and down stably. The movable rod and the fixed rod of the telescopic frame 5 are fixed by a second screw, which makes it convenient for the staff to fix the height of the telescopic frame 5. The first slide 9 and the crossbar 7 are fixed by a third screw, which makes it convenient for the staff to fix the position of the first slide 9.

[0025] The working principle of this utility model is as follows: First, the U-shaped frame 1 is clamped onto one side of the external component fixing plate. Then, the screw 3 is rotated, causing the clamp 2 to move downwards. This allows the U-shaped frame 1 and clamp 2 to hold the external component's support plate, ensuring stable installation. Next, when the patient's affected limb is placed into the lifting ring, to lift the limb, the first screw 13 is rotated to move it out of the thread hole 14. Then, the winding roller 15 is rotated to wind up the rope 12, thus adjusting the height of the lifting ring. This allows medical staff to lift the patient's affected limb with less effort. The patient's affected limb is lifted. When it is necessary to move the telescopic frame 5, the medical staff pulls the round rod 22, which moves along the second slide groove 21 until it separates from the insertion hole 18, and the spring 20 contracts. At this time, the moving frame 19 is unrestricted. Then, the telescopic frame 5 is pushed, so that the moving frame 19 moves along the guide rail 17 to the required position. Then, the round rod 22 is released, and the spring 20 rebounds and extends, so that the round rod 22 is inserted into the corresponding insertion hole 18, thereby adjusting and fixing the position of the telescopic frame 5 and the suspension assembly as a whole.

[0026] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
