[0028] See also Figures 1 to 5 A protective splint 22 for fracture fixation includes a wide cloth strip 1, a wrapping member 2 is provided on the front and back of the wide cloth strip 1, and the wrapping member 2 includes four storage bags 21 sewn on the back;
[0029] The inside of the four storage bags 21 are all plugged with plywood 22, three straps 23 are sewn on the front of the wide cloth strip 1, and three fixed disks 24 are fixedly connected to the front of the wide cloth strip 1. An opening 25 is provided on the outside of the fixed disk 24, and a rotating rod 26 is rotatably connected to the side of the fixed disk 24 close to the wide cloth strip 1. The other end of the rotating rod 26 passes through one side of the front of the fixed disk 24, and a rotating disk 27 is fixedly connected to the outside of the rotating rod 26. The rotating disk 27 is inside the fixed disk 24, and a column 28 is fixedly connected to the side of the fixed disk 24 away from the wide cloth strip 1. The strap 23 is wrapped around the outside of the wide cloth strip 1 and then inserted into the inside of the opening 25, and the strap 23 is wrapped around the outside of the wide cloth strip 1 and then sleeved on the outside of the column 28.
[0030] A locking assembly 29 is provided inside the fixed disk 24 . The locking assembly 29 includes a ratchet 291 fixedly connected to the outside of the rotating rod 26 . Two pawls 292 are hinged to the inner wall of the fixed disk 24 . Both pawls 292 are clamped to the outside of the ratchet 291 .
[0031] Two first return springs 293 are fixedly connected to the inner wall of the fixed plate 24 , and the other ends of the two first return springs 293 are fixedly connected to the outer sides of the two pawls 292 respectively.
[0032] A through hole is formed on the surface of the binding strap 23 , and the binding strap 23 is sleeved on the outside of the column 28 through the through hole. The shape of the column 28 matches the shape of the through hole.
[0033] By adopting the above technical solution, first, the four splints 22 are inserted into the storage bag 21 at the corresponding positions, and the wide cloth strip 1 is wrapped around the patient's affected limb according to the shape and size of the splint 22, and then the three straps 23 are wrapped around the outside of the wide cloth strip 1 and inserted into the fixed disk 24 through the opening 25 on the outside of the fixed disk 24. When the strap 23 is sleeved on the outside of the column 28 in front of the turntable 27, and the strap 23 is locked by the disassembly component 3, the counterclockwise rotation rod 26 is then rotated to drive the turntable 27 inside the fixed disk 24 to rotate, and after the turntable 27 rotates, it will drive the column 28 to rotate, and the strap 23 is wrapped around the front of the turntable 27 through the column 28. As the strap 23 is wrapped, the splint 22 will also be bound to the outside of the patient's affected limb. During the rotation of the rotating rod 26, the ratchet 291 on the outside of the rotating rod 26 will be driven to rotate counterclockwise. When the pawl 292 rotates counterclockwise, the ratchet 291 will push the pawl 292 and pass through the pawl 292 smoothly. Then the pawl 292 is reset by the first reset spring 293. When the rotating rod 26 rotates clockwise, the ratchet 291 will be locked by the pawl 292 and cannot rotate. Since the tightness of the strap 23 on the splint 22 can be adjusted by the rotating rod 26, when the edema of the patient's affected limb gradually subsides, the patient can adjust the tightness of the strap 23 by rotating the rotating rod 26, avoiding the need to find a doctor to repeatedly disassemble the strap 23, reducing the tedious steps of re-tying the splint 22, and ensuring the positioning effect of the fracture.
[0034] Specifically, such as Figure 5 As shown, a disassembly component 3 is provided on the surface of the fixed disk 24, and the disassembly component 3 includes a movable plate 31 hinged inside the opening 25 on the surface of the fixed disk 24, and limiting grooves 32 are provided on both sides of the inside of the opening 25.

The opposite surfaces of the two pressing plates 36 are fixedly connected to the same second return spring 37 , which is located inside the movable groove 33 .
[0036] Slide grooves 34 are provided on the upper and lower sides of the movable plate 31. The two slide grooves 34 are respectively connected to the two movable grooves 33, and the two slide grooves 34 are respectively connected to the two limit grooves 32. After the back of the movable plate 31 is rotated, it overlaps with the end of the column 28 close to the movable plate 31.
[0037] Slide blocks 35 are slidably connected in the two sliding grooves 34 . The slide blocks 35 are engaged in the limiting grooves 32 after being moved. The shape of the slide blocks 35 matches the shape of the limiting grooves 32 .
[0038] By adopting the technical scheme, first, the two pressing plates 36 are pressed towards the middle, so that the two pressing plates 36 slide in the two movable grooves 33 while driving the two sliding blocks 35 to slide in the two sliding grooves 34, when the two sliding blocks 35 move towards the middle, the two sliding blocks 35 will be separated from the two limiting grooves 32, at this time, the movable plate 31 can be pulled by the two pressing plates 36 to be separated from the opening 25, finally, the bandage 23 is sleeved outside the stand column 28, after the movable plate 31 is re-locked in the opening 25, the stand column 28 will be in contact with the movable plate 31, so that the bandage 23 cannot be separated from the stand column 28, since the movable plate 31 can close the opening 25 and be attached to the stand column 28, the movable range of the bandage 23 outside the stand column 28 is limited, not only the bandage 23 can be locked and disassembled, but also the bandage 23 which can move in a small range can be adjusted in a small range according to the patient's physical condition, so as to guarantee the stability of the bandage 23 when the bandage 23 is bound to the splint 22.
[0039] Working principle: insert four splints 22 into the corresponding storage bags 21, and wrap the wide cloth strip 1 around the patient's affected limb, then wrap three bandages 23 outside the wide cloth strip 1, press the two pressing plates 36 towards the middle, so that the pressing plate 36 slides in the two movable grooves 33 while driving the two sliding blocks 35 to slide in the two sliding grooves 34, and the sliding block 35 is separated from the limiting groove 32, the movable plate 31 can be separated from the opening 25, finally, the bandage 23 is sleeved outside the stand column 28, when the rotating rod 26 is rotated counterclockwise, the rotating disc 27 in the fixed disc 24 is rotated, so that the bandage 23 is wound in front of the rotating disc 27 through the stand column 28, as the bandage 23 is wound, the splint 22 will also be bound outside the patient's affected limb, and in the process of rotating the rotating rod 26, the ratchet wheel 291 outside the rotating rod 26 will rotate counterclockwise, when the pawl 292 rotates counterclockwise, the ratchet wheel 291 will push the pawl 292 and smoothly pass through the pawl 292, then the pawl 292 is reset by the first reset spring 293, when the rotating rod 26 rotates clockwise, the ratchet wheel 291 will be locked by the pawl 292 and cannot rotate.
