The pulling wing plates 2503 have a certain length, the two pulling wing plates 2503 extend out towards the same side of the chest protector body 2501, one end of the pulling wing plates 2503 in the length direction is fixedly connected with the chest protector body 2501, the other end of the pulling wing plates 2503 in the length direction is rotatably connected with the rotating connecting plate 26 through a rotating shaft, all the third longitudinal plates 2502 are positioned between the two pulling wing plates 2503, the pulling wing plates 2503 and the chest protector body 2501 are integrally formed, and the formed chest protector splint 25 is approximately in a U-shaped structure.

The shoulder joint external fixing device with the structure has the following advantages:

1. can self-regulate to adapt to hematoma change after shoulder joint fracture and trauma; maintaining the stability of the external fixation in dynamic balance; the shoulder wrapping plate adopts three sections of movable connection, and does not influence the small-range abduction of the shoulder joint;

2. the chest protection splint conforms to the external fixing mode of symmetrical extrusion of the small splint in traditional Chinese medicine; the oblique woven belt is prevented from moving, and the optimal constraint force angle of the fixing ring is kept.

The invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-described manner. Various insubstantial improvements are made by adopting the method conception and the technical proposal of the utility model; or without improvement, the above conception and technical solution of the present invention can be directly applied to other occasions, all within the protection scope of the present invention.
