[0026] The tightening device provided by the embodiment is similar to a scissors, comprising a first tool body 1 and a second tool body 2 hinged to each other, the first tool body 1 is provided with a first handle 101 and a first clamping unit 103, the second tool body 2 is provided with a second handle 201 and a second clamping unit 203, the first clamping unit 103 and the second clamping unit 203 clamp two ends of a bandage, then the first handle 101 and the second handle 201 are operated to increase the distance between the first clamping unit 103 and the second clamping unit 203, so as to tighten the bandage. Further, the first handle 101 and the second handle 201 are further provided with a locking structure for locking the angle of the first handle 101 and the second handle 201, so as to facilitate the fixation of the tightened bandage. Since the metal bandage is different from the flexible bandage in knot fixation, a locking buckle is required to fix the metal bandage, and the locking structure can fix the bandage in the state of being tightened, so as to realize the binding.

[0027] Further, the locking structure comprises a locking shaft 31 and a locking nut 32, one end of the locking shaft 31 is arranged on the first handle 101, the other end penetrates through the second handle 201 and is threadedly connected with the locking nut 32.

[0028] In a preferred embodiment, the first tool body 1 is further provided with a first connecting shaft 102 connecting the first handle 101 and the first clamping unit 103, and the second tool body 2 is further provided with a second connecting shaft 202 connecting the second handle 201 and the second clamping unit 203.

[0029] The first connecting shaft 102 and the second connecting shaft 202 are hinged and bent away from each other at the hinged point, so that the first connecting shaft 102 and the first handle 101 are distributed on one side of the central axis of the tightening device, and the second connecting shaft 202 and the second handle 201 are distributed on the other side of the central axis of the tightening device.

[0030] The first clamping unit 103 and the second clamping unit 203 are arranged at the free ends 104 of the first connecting shaft 102 and the second connecting shaft 202, respectively.

[0031] The first tool body 1 and the second tool body 2 of the tightening device of the embodiment are similar to a scissors, but the first tool body 1 and the second tool body 2 of the embodiment are hinged but not cross arranged, but are arranged in a non-cross manner through the bent first connecting shaft 102 and the second connecting shaft 202, so that when the first handle 101 and the second handle 201 are close to each other, the distance between the free ends 104 of the first connecting shaft 102 and the second connecting shaft 202 is increased, and the bandage at the two ends of the first clamping unit 103 and the second clamping unit 203 is tightened.

[0032] In a preferred embodiment, the first clamping unit 103 and the second clamping unit 203 are identical in structure. Taking the first clamping unit 103 as an example, the first clamping unit 103 comprises a fixed end 1031, a moving block 1032 and a driving mechanism. The driving mechanism is connected to the moving block 1032 and is configured to drive the moving block 1032 to move relative to the connecting shaft. One end of the bandage is clamped between the moving block 1032 and the gap of the fixed end 1031.

[0033] Further, the free end 104 of the first connecting shaft 102 is horizontally arranged, so that the moving block 1032 moves in the horizontal direction.

[0034] Further, a groove 1036 is arranged on the first connecting shaft 102 at a position corresponding to the moving block 1032. The moving block 1032 is provided with a limiting block 1037, which is located in the groove 1036 and moves in the groove 1036. When the limiting block 1037 moves with the moving block 1032, the inner wall of the groove 1036 is configured to limit the movement displacement of the moving block 1032.

[0035] Further, an elastic body is arranged in the groove 1036, and one end of the elastic body is connected to the limiting block 1037. For example, when the moving block 1032 moves away from the fixed end 1031, the elastic body is stretched or compressed, increasing the gap between the moving block 1032 and the fixed end 1031. The bandage is placed in the gap between the moving block 1032 and the fixed end 1031. Then, due to the action of the elastic body, the limiting block 1037 is driven to return to the initial position, thereby driving the moving block 1032 to move towards the fixed end 1031, and then clamping the bandage.

[0036] Further, after clamping the bandage, the first clamping unit 103 further comprises a fixing stud. A threaded hole 1039 is arranged on the limiting block 1037, and a through hole 1038 is arranged on the fixed end 1031. The fixing stud is screwed through the through hole 1038 of the fixed end 1031 and the threaded hole 1039, thereby fixing the limiting block 1037, and further fixing the gap between the moving block 1032 and the fixed end 1031, and clamping the bandage.

[0037] Further, the driving mechanism comprises a pressing shaft 1033, a driving shaft 1034, a stand 1035 arranged on the first connecting shaft 102, the pressing shaft 1033, the stand 1035 and one end of the driving shaft 1034 are rotationally connected, and the other end of the driving shaft 1034 is rotationally connected with one end of the moving block 1032 away from the fixed end 1031. The stand 1035 is arranged, one end of the driving shaft 1034 is rotationally connected with the stand 1035, and the other end is rotationally connected with one end of the moving block 1032 away from the fixed end 1031, so that the driving shaft 1034 has a distance from the first connecting shaft 102, and in this embodiment, after the pressing shaft 1033 is pressed in the direction close to the first connecting shaft 102, the driving shaft 1034 carries the moving block 1032 due to the action of the lever, so that the moving block 1032 moves in the direction away from the fixed end 1031.

[0038] The working principle of the tightening device in this embodiment is as follows:

[0039] First, the pressing shaft 1033 is pressed in the direction close to the first connecting shaft 102 and the second connecting shaft 202, the driving shaft 1034 carries the moving block 1032 due to the action of the lever, so that the moving block 1032 moves in the direction away from the fixed end 1031, thereby increasing the gap between the moving block 1032 and the fixed end 1031, and then the elastic body drives the limiting block 1037 to return to the initial position, thereby driving the moving block 1032 to move in the direction close to the fixed end 1031, and then clamping the bandage. Further, the fixing stud is threadedly connected with the threaded hole 1039 on the limiting block 1037 through the through hole 1038 of the fixed end 1031, so as to fix the limiting block 1037, and then fix the gap between the moving block 1032 and the fixed end 1031, and further clamp the bandage. Then, when the first handle 101 and the second handle 201 are close to each other, the distance between the free ends 104 of the first connecting shaft 102 and the second connecting shaft 202 is increased, the bandage at both ends of the first clamping unit 103 and the second clamping unit 203 is tightened, and then the fixing nut is tightened, so as to fix the distance between the first handle 101 and the second handle 201, and at this time, the bandage can be fixed.
