In actual application, the first straps 12 can be adhered by Velcro or plugged in by snap-on buckles). In this embodiment, the three first straps 12 can not only ensure that the lumbar support plate 1 is in contact with the patient's body, but also prevent the lumbar support plate 1 from sliding downward; Figure 1 As shown in the figure and the legs 4, the lumbar support plate 1 is in an "I" shape and has an overall arc-shaped structure. The rear end of the lumbar support plate 1 is fixedly connected to the first strap 12, and the front end of the lumbar support plate 1 is connected to the first strap 12 through a connecting buckle 11. Two of the first straps 12 are horizontal and are used to make the lumbar support plate 1 close to the side of the patient's upper body. The other first strap 12 is inclined and is used to prevent the lumbar support plate 1 from sliding downward. The connecting buckle 11 is made of plastic, such as the connecting buckle on a backpack.

[0027] refer to Figure 1 、 Figure 2 and Figure 4 The left side wall of the first mounting plate 2 is provided with a mounting groove, in which a screw rod 16 is vertically installed to rotate with it, and a connecting block 15 is set on the screw rod 16 to be threaded with it and with the same width as the groove width of the mounting groove. A connecting block 15 is also fixed to the left bottom of the second mounting plate 10, and a connecting rod 3 is provided on the left side of the first mounting plate 2. Both ends of the connecting rod 3 are hinged to one of the connecting blocks 15 through a spherical hinge joint 14 (the screw rod 16, connecting block 15, connecting rod 3 and spherical hinge joint 14 in this paragraph constitute the adjustment mechanism for adjusting the inclination angle of the second mounting plate 10. In actual application, the connecting block 15 on the screw rod 16 can also be a "T"-shaped structure, and the mounting groove is also a T-shaped slot). In this embodiment, the connecting block 15 is moved up and down by rotating the screw rod 16, and the inclination angle of the second mounting plate 10 is adjusted under the action of the spherical hinge joint 14, thereby adjusting the angle between the patient's upper arm and shoulder, thereby preventing problems such as muscle atrophy, joint stiffness, and poor blood circulation caused by single angle fixation;

[0028] like Figure 1 、 Figure 2 and Figure 4As shown, the left side wall of the first mounting plate 2 is provided with a protrusion for mounting the screw rod 16, the lower end of the screw rod 16 is sleeved with a fixing block 17, and the side wall of the fixing block 17 is provided with anti-slip grooves; Figure 1 A first fixing plate 9 is provided above the second mounting plate 10, and the right end of the second mounting plate 10 is hinged to the first fixing plate 9 through a rotating shaft 18. The left side of the first fixing plate 9 is also hinged to the second fixing plate 5 through the rotating shaft 18. The two rotating shafts 18 are both equipped with rotating blocks 4 for fixing the rotation angles of the first fixing plate 9 and the second fixing plate 5 respectively. In this embodiment, the first fixing plate 9 can swing back and forth relative to the second mounting plate 10 along the plane where the second mounting plate 10 is located through two screw rods 16. At the same time, the second fixing plate 5 can also swing back and forth relative to the first fixing plate 9 along the plane where the second mounting plate 10 is located, thereby facilitating the patient to further change the angle between the upper arm and the shoulder and the angle between the forearm and the upper arm, thereby further preventing problems such as muscle atrophy, joint stiffness, and poor blood circulation caused by single-angle fixation;

[0029] like Figure 1 As shown, one end of one of the rotating shafts 18 is fixed to the right bottom of the first fixed plate 9, and the other end of the rotating shaft 18 independently passes through the bottom of the second mounting plate 10, and the end passing through the second mounting plate 10 is fitted with a rotating block 4 that is threadedly engaged with it. By rotating the rotating block 4 so that it is pressed against the second mounting plate 10, the position of the first fixed plate 9 after rotation can be fixed;

[0030] like Figure 1 As shown, the left end of the first fixing plate 9 is in a "concave" shape, and the right end of the second fixing plate 5 is in a "convex" shape and is inserted into the left end of the first fixing plate 9. A sliding groove communicating with the upper and lower parts is opened at the left bottom of the first fixing plate 9, and one end of another rotating shaft 18 is fixed to the right bottom of the second fixing plate 5. One end of the rotating shaft 18 independently passes through the sliding groove and slides with it left and right. The end of the rotating shaft 18 passing through the sliding groove is also covered with a rotating block 4 that is threadedly matched with it. By rotating the rotating block 4 so that it is pressed against the second fixing plate 5, the position of the second fixing plate 5 after rotation can be fixed. At the same time, by sliding the second fixing plate 5 left and right, the depth of the right end of the second fixing plate 5 inserted into the left end of the first fixing plate 9 can be changed, and the position of the rotating shaft 18 can also be made suitable for patients of different body shapes.

[0031] A hand pad 6 is fixed on the top of the second fixing plate 5 and the first fixing plate 9, and an arc-shaped pad 8 is fixed on the front and rear ends of each hand pad 6, one of which is fixed with a second strap 7, and the movable end of the second strap 7 is bonded to the other arc-shaped pad 8 by Velcro (the arc-shaped pad 8 and the second strap 7 in this paragraph constitute the limiting component for limiting the movement of the patient's arm as a whole, and the second strap 7 can also be an elastic band). In this embodiment, three groups of arc-shaped pads 8 and second straps 7 are used to limit the patient's upper arm, forearm and wrist respectively, so as to prevent the shaking of the affected limb from affecting the recovery of the shoulder to the greatest extent, and the hand pad 6 and the arc-shaped pad 8 both have a certain hardness and toughness.

[0032] When using this embodiment, the patient is first placed on the two hand pads 6, and the second fixing plate 5 is slid left and right to change the depth of the right end of the second fixing plate 5 inserted into the left end of the first fixing plate 9 so that the position of the rotating shaft 18 connecting the second fixing plate 5 and the first fixing plate 9 corresponds to the patient's elbow. Then, the three second straps 7 are fixed, and then the three first straps 12 are respectively passed around the patient's chest, abdomen and shoulder on the healthy limb side and fixed. Then, according to the patient's use time, condition and other factors, the fixing block 17 is rotated to change the position of the connecting block 15 on the screw rod 16 , so that the angle between the second mounting plate 10 and the first mounting plate 2 is changed to adjust the angle between the patient's upper arm and the shoulder. The rotating block 4 on the rotating shaft 18 connecting the first fixing plate 9 and the second mounting plate 10 can be loosened, and the first fixing plate 9 is rotated to a suitable angle and the rotating block 4 is tightened to further adjust the angle between the patient's upper arm and the shoulder. The rotating block 4 on the rotating shaft 18 connecting the second fixing plate 5 and the first fixing plate 9 can be loosened, and the second fixing plate 5 is rotated to a suitable angle and the rotating block 4 is tightened to adjust the angle between the patient's forearm and the upper arm.
