[0022] Embodiment 2:

[0023] like Figure 1 and Figure 2 As shown, the first driving mechanism 4 that matches the adjacent adjustable clamping mechanism 3 is installed on one side of the outer surface of the bottom plate 1 and the top plate 2, and the first driving mechanism 4 includes a first pulley 41, one end of the first bidirectional screw 32 extends to the outside of the corresponding bottom plate 1 and the top plate 2, and the first pulley 41 is fixedly sleeved on the outer surface of one end of the first bidirectional screw 32, and a first synchronous belt 42 is meshed and connected between two adjacent first pulleys 41, and a first knob 43 is fixedly connected to one end of the first bidirectional screw 32. The first knob 43 rotates to drive the corresponding first bidirectional screw 32 to rotate, and the two first bidirectional screws 32 rotate at the same time through the first pulleys 41 and the first synchronous belt 42 on both sides, without the need for separate adjustment, reducing the workload, thereby solving the problem of the existing orthopedic splint that the two second threaded rods need to be rotated separately when adjusting the horizontal distance of the clamping block, which increases the workload.

[0024] Embodiment 3:

[0025] like Figure 1 and Figure 3As shown, a fixing mechanism 5 is installed on the upper surface of the base plate 1, and the fixing mechanism 5 includes a second stroke groove 51 symmetrically opened on both sides of the upper surface of the base plate 1, and a second bidirectional screw rod 52 is rotatably connected between the two second stroke grooves 51, and the outer surface of the second bidirectional screw rod 52 is threadedly connected to a second slider 53 that is slidably connected to the second stroke groove 51, and the top of the second slider 53 is fixedly connected to a first L-shaped plate 54, and one end of the second bidirectional screw rod 52 is fixedly connected to a second knob 55. Dovetail blocks are symmetrically fixedly connected to both sides of the lower surface of the first L-shaped plate 54, and a dovetail groove 56 that matches the dovetail block is opened on the upper surface of the base plate 1. The second knob 55 rotates to drive the second bidirectional screw rod 52 to rotate, and drives the opposite side of the first L-shaped plate 54 on both sides through the thread, so as to facilitate rapid connection and separation with the second L-shaped plate 63, thereby realizing rapid installation and removal of the orthopedic splint, thereby solving the problem that the existing orthopedic splint needs to rotate multiple first screw rods when removing, which causes inconvenience in removal.

[0026] Embodiment 4:

[0027] like Figure 1 and Figure 2 As shown, the lower surface of the top plate 2 is penetrated by an adjustable clamping mechanism 6 that matches the fixing mechanism 5. The adjustable clamping mechanism 6 includes four one-way screws 61 in a rectangular array that are rotatably connected to the lower surface of the top plate 2.

The one-way screw 61 rotates to drive the moving plate 62 and the second L-shaped plate 63 to move up and down through the thread, so that the distance between the upper and lower arc-shaped orthopedic splint bodies 34 can be changed by matching with the first L-shaped plate 54.

[0028] Embodiment 5:

[0029] like Figure 1 and Figure 2 As shown, the upper surface of the top plate 2 is installed with a second driving mechanism 7 matched with the adjustable clamping mechanism 6, the second driving mechanism 7 includes a second pulley 71, the top ends of the four one-way screws 61 extend to the top of the top plate 2, and the second pulley 71 is fixedly sleeved on the top outer surface of the one-way screw 61, and the four second pulleys 71 are meshed and connected with a second synchronous belt 72, and the top end of the one-way screw 61 is fixedly connected with a third knob 73. The third knob 73 rotates to drive the one-way screw 61 to rotate, and the four one-way screws 61 are driven to rotate by the second pulley 71 and the second synchronous belt 72 at the same time, so that quick adjustment can be performed, thereby solving the problem that the existing orthopedic splint needs to rotate the four first threaded rods separately when adjusting the upper and lower clamping degrees, which increases the workload.

[0030] Working principle: when in use, first rotate the upper and lower first knobs 43 according to the required position of the splint. The rotation of the first knob 43 drives the corresponding first bidirectional screw rod 32 to rotate, and the two first bidirectional screw rods 32 are rotated simultaneously through the first pulleys 41 and the first synchronous belt 42 on both sides. The rotation of the first bidirectional screw rod 32 drives the first sliders 33 on both sides to move relative to each other, thereby driving the arc-shaped orthopedic splint bodies 34 on both sides to move relative to each other, which can change the horizontal distance between the arc-shaped orthopedic splint bodies 34 on both sides. There is no need to adjust them separately, which reduces the workload, thereby solving the problem of the existing orthopedic splint that requires rotating the two second threaded rods separately when adjusting the horizontal distance of the clamping block, which increases the workload.

[0031] Then place the top plate 2 above the bottom plate 1, turn the second knob 55, and the rotation of the second knob 55 drives the second bidirectional screw rod 52 to rotate, and drives the opposite side of the first L-shaped plate 54 on both sides through the thread. When the first L-shaped plate 54 and the second L-shaped plate 63 are clamped, the orthopedic splint can be fixed, and when the first L-shaped plate 54 and the second L-shaped plate 63 are separated, the orthopedic splint can be disassembled, thereby realizing the rapid installation and disassembly of the orthopedic splint, thereby solving the problem that the existing orthopedic splint needs to rotate multiple first screws during disassembly, causing inconvenience in disassembly.

[0032] When clamping is required, it is only necessary to turn the third knob 73. The rotation of the third knob 73 drives the one-way screw 61 to rotate, and the four one-way screws 61 are driven to rotate at the same time through the second pulley 71 and the second synchronous belt 72, so that quick adjustment can be performed, thereby solving the problem of the existing orthopedic splint that the four first threaded rods need to be rotated separately when adjusting the upper and lower clamping degrees, which increases the workload.

[0033] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
