[0021] As a technical optimization solution of the utility model, the end of the rotating block 602 is fixedly connected with the first protrusion 601, and the end of the steel needle 8 has a conical structure, so the rotating block 602 can be easily rotated through the first protrusion 601.

[0022] As a technical optimization solution of the present invention, one end of the cross section of the clamping block 604 is a trapezoidal structure, and the other end of the cross section of the clamping block 604 is a T-shaped structure, so it can play a guiding role when the clamping block 604 is engaged with the bow body 1.

[0023] As a technical optimization solution of the present invention, the cross-section of the bow body 1 is a U-shaped structure, and one end of the bow body 1 is fixedly connected to a connecting ring 2, so that it can be connected to the sling through the connecting ring 2.

[0024] As a technical optimization scheme of the utility model, the fixed structure 7 includes a swivel 702, which is rotatably connected to the connecting sleeve 4, and a plurality of guide grooves 703 are provided on the swivel 702. A plurality of slide rods 704 are slidably connected to the connecting sleeve 4, and a guide shaft 705 is fixedly connected to the slide rod 704. The end of the guide shaft 705 extends to the inside of the guide groove 703 and is slidably connected to the swivel 702. A splint 706 is fixedly connected to the end of the slide rod 704, and the ends of the plurality of splints 706 are in contact with the steel needle 8. A plurality of second springs 707 are provided inside the connecting sleeve 4, and one end of the second spring 707 is in contact with the slide rod 704, and the other end of the second spring 707 is in contact with the connecting sleeve 4, thereby enabling the connection sleeve 4 and the steel needle 8 to be fixed.

The connecting ring 2 can be connected to the sling. A weight can be connected to the end of the sling to pull the patient's bones, thereby achieving a therapeutic effect. When the traction bow needs to be disassembled after the treatment, the rotating block 602 can be rotated through the first protrusion 601. When the rotating block 602 rotates, the clamping block 604 can be driven to move away from the bow body 1 through the connecting rope 603. When the clamping block 604 and the bow body 1 are not engaged, the connecting block 3 can be separated from the bow body 1, and then the rotating ring 702 can be rotated through the second protrusion 701. During the rotation of the swivel 702, the guide shaft 705 will move inside the guide groove 703. During the movement of the guide shaft 705 inside the guide groove 703, the slide bar 704 will drive the splint 706 to move away from the steel needle 8, and the second spring 707 will contract, so that there is no conflict between the multiple splints 706 and the steel needle 8. Then the connecting sleeve 4 can be removed from the end of the steel needle 8, thereby realizing the rapid disassembly of the connecting sleeve 4. At this time, the rapid disassembly of the traction bow is completed, thereby shortening the disassembly time and improving the disassembly efficiency.
