Then, the free end of the strap is folded back and passes through the second avoidance hole 17 of the locking support 10. After the free end of the strap passes out from the second avoidance hole 17, it can pass through the third clamping plate 5, the second clamping plate 4, and the first clamping plate 3 in sequence. The clamping member is arranged to be switchable between an open position and a buckling position. When the clamping member is in the open position, the clamping member can rotate freely relative to the locking support 10. At this time, the clamping member and the locking support 10 cannot clamp the strap, so that the strap can be pulled to adjust the binding force, and the strap can move in the first avoidance hole 16 and the second avoidance hole 17 of the locking support 10. After the binding force of the strap is adjusted appropriately, the clamping member is switched from the open position to the buckling position. At this time, the clamping member can cooperate with the locking support 10 to clamp the strap, and the strap cannot be pulled, so that the surrounding perimeter of the strap is fixed. When the clamping member is in the open position, the first clamping plate 13 is inserted into the first avoidance hole 16, and the second clamping plate 14 is inserted into the second avoidance hole 17. The first clamping plate 13 exerts a pressure on the strap to make it fit with the locking support 10, and the second clamping plate 14 exerts a pressure on the strap to make it fit with the locking support 10. A part of the strap is located between the first clamping plate 13 and the second clamping plate 14. Therefore, through the cooperation of the first clamping plate 13 and the second clamping plate 14 with the locking support 10, the clamping and fixing of the strap are realized. The structure is simple and compact, the operation is convenient, the strap is not easy to loosen, and the reliability is good.The rotating plate 12 has a certain length and width, the length direction of the rotating plate 12 is parallel to its rotation center line, the length direction of the rotating plate 12 is perpendicular to its width direction, one end of the rotating plate 12 in the width direction is fixedly connected to the locking support 10, and the locking hook plate 15 is fixedly connected to the other end in the width direction of the rotating plate 12, the first clamping plate 13 and the second clamping plate 14 both have a certain length and width, the length direction of the first clamping plate 13 and the second clamping plate 14 is parallel to the length direction of the rotating plate 12, the first clamping plate 13, the second clamping plate 14 and the locking hook plate 15 extend toward the same side of the rotating plate 12 and the second clamping plate 14 is located between the first clamping plate 13 and the locking hook plate 15, the first clamping plate 13, the second clamping plate 14 and the locking hook plate 15 are arranged in sequence along the width direction of the rotating plate 12, and the first clamping plate 13 is located between the second clamping plate 14 and the end of the rotating plate 12 that is rotatably connected to the locking support 10. The width direction of the first clamping plate 13 is perpendicular to the length direction thereof, the width direction of the second clamping plate 14 is perpendicular to the length direction thereof, the width direction of the first clamping plate 13 is parallel to the width direction of the second clamping plate 14, and the width directions of the first clamping plate 13 and the second clamping plate 14 are perpendicular to the length direction and the width direction of the rotating plate 12, the width of the first clamping plate 13 is smaller than the width of the second clamping plate 14, and there is a certain distance between the first clamping plate 13 and the second clamping plate 14.

[0098] like Figure 28 to Figure 31 As shown, there is a certain distance between the lock hook plate 15 and the second clamping plate 14, and the lock hook plate 15 has a certain length and width. The length direction of the lock hook plate 15 is parallel to the length direction of the rotating plate 12, and the width direction of the lock hook plate 15 is parallel to the width direction of the second clamping plate 14. Preferably, the first end of the lock hook plate 15 is fixedly connected to the rotating plate 12, and the second end of the lock hook plate 15 is a hook-shaped structure. The first end and the second end of the lock hook plate 15 are the opposite ends in the width direction of the lock hook plate 15. The second end of the lock hook plate 15 is used to hook the locking support 10 when the clamping piece is in the buckled position, thereby keeping the clamping piece in the buckled position, keeping the clamping piece and the locking support 10 in a state of clamping the strap to prevent the strap from loosening, which is convenient, fast, safe and reliable.

[0099] The traditional Chinese medicine small splint external fixation device of the above structure has the following advantages:

[0100] 1. Use a single strap to facilitate the adjustment of the splint position and maintain the sensitivity of the restraining force ring; use a locking device to limit the loosening of the strap to ensure the reliability of the restraining force ring of the splint device;

[0101] 2. The transverse connection device is used to shape the entire splint device according to the transverse biological morphology of the patient's arm before external fixation. The splint is positioned according to the position where the splint should be placed. It mainly connects the first, second and third splint components. After shaping, the splint device can be placed on the affected limb from bottom to top to form a painless wearing method. The buckle and limiter structure are used to limit the random sliding of the splint.

[0102] 3. Aluminum alloy rails are used to position the splint through transverse shaping, which improves the simplicity of external fixation operation.

[0103] The present invention is described above by way of example in conjunction with the accompanying drawings. Any non-substantial improvements made by using the method concept and technical solution of the present invention are within the protection scope of the present invention.
