After the adjustment, the fixing component 1 3 and the fixing component 2 4 are opened, and then the patient's arm is located in the inner walls of the fixing component 1 3 and the fixing component 2 4, which are adjusted and fixed in turn, so that the patient's arm is fixed above the fixing plate 1. At this time, the protective pad 5 can provide support and protection for the patient during treatment.

[0028] like Figure 2 , Figure 3 As shown, the movable adjustment component 2 includes a limiting slide plate 21, the outer wall of the limiting slide plate 21 is movably connected to the inner cavity in the middle of the left part of the fixed plate 1, and the left side of the limiting slide plate 21 is fixedly connected to a supporting movable plate 22, and the supporting movable plate 22 is located on the left side of the fixed plate 1;

[0029] Since the upper outer wall of the limiting slide plate 21 is located in the limiting groove opened in the middle of the fixing plate 1, the moving range of the supporting movable plate 22 is limited under the action of the limiting slide plate 21, thereby preventing it from falling off.

[0030] The front and rear sides of the right side of the supporting movable plate 22 are fixedly connected with sliding rods 23, and the two sliding rods 23 are respectively located at the front and rear sides of the limiting slide plate 21, and the outer walls of the two sliding rods 23 are respectively movably sleeved with the inner cavity of the left part of the fixed plate 1;

[0031] Through the action of the slide bar 23, the supporting movable plate 22 can be steadily and smoothly moved on the left side of the fixed plate 1, so that it is convenient for medical staff to adjust the length.

[0032] The front of the upper part of the limiting slide plate 21 is fixedly connected with an L-shaped fixing plate 24, the inner wall of the L-shaped fixing plate 24 overlaps the outer wall of the fixing plate 1, the inner cavity of the front part of the L-shaped fixing plate 24 is movably sleeved with a screw 25, and the rear part of the outer wall of the screw 25 is threadedly sleeved with the inner cavity of the fixing plate 1;

[0033] Since there are several fixing holes at the front of the fixing plate 1, the limiting slide plate 21 can be fixed by the L-shaped fixing plate 24 and the screw 25, so that the extension length of the supporting movable plate 22 can be adjusted and fixed, so as to facilitate the purpose of quick adjustment according to the patient's arm length when in use.

[0034] The fixed component 1 3 includes an arc-shaped support plate 31, the lower surface of the arc-shaped support plate 31 is fixedly connected to the upper surface of the support movable plate 22, the inner wall of the rear part of the arc-shaped support plate 31 is rotatably connected to the arc-shaped fixed plate 32, and the inner walls of the arc-shaped fixed plate 32 and the arc-shaped support plate 31 are both fixedly connected to the protective component 33;

[0035] Since the arc-shaped support plate 31 and the arc-shaped fixing plate 32 are both arc-shaped, they can fit well with the patient's arm when fixing it, thereby facilitating fixation.

[0036] The inner wall of the front part of the arc-shaped fixing plate 32 is rotatably connected with the second L-shaped fixing plate 34, the fixed shaft of the second L-shaped fixing plate 34 rotatably connected with the arc-shaped fixing plate 32 is slidably connected with the inner wall of the front part of the arc-shaped fixing plate 32, and the inner cavity of the lower part of the second L-shaped fixing plate 34 is threadedly connected with the inner cavity of the front part of the arc-shaped support plate 31;

[0037] The inner cavity of the front part of the L-shaped fixing plate 31 can be threadedly connected with the L-shaped fixing plate 34 by screws. At the same time, since the L-shaped fixing plate 34 and the arc-shaped fixing plate 32 are rotatably connected, the L-shaped fixing plate 34 can also move back and forth on the inner wall of the arc-shaped fixing plate 32, thereby facilitating adjustment of the size between the arc-shaped support plate 31 and the arc-shaped fixing plate 32, thereby facilitating quick adjustment and fixation according to the thickness of the patient's arm.

[0038] like Figure 4 , Figure 5 As shown, the protection component 33 includes a waterproof layer 331, the outer wall of the waterproof layer 331 is fixedly connected to the inner wall of the arc-shaped fixed plate 32, and the inner wall of the waterproof layer 331 is fixedly connected with a wear-resistant layer 332;
