[0023] The fixing mechanism 8 includes a through slot 801, a through slot 801 is provided at the bottom of the through hole 5, a groove 802 is provided on the inner side of the through slot 801, a clamping slot 803 is provided at the bottom of the rotating shaft 3, a clamping rod 804 is installed inside the through slot 801, the lower end of the clamping rod 804 is located below the support plate 4 and is fixed with a pull ring 805, the upper end of the clamping rod 804 is located inside the clamping slot 803, a movable block 806 is fixed to the outer wall of the clamping rod 804, the end of the movable block 806 is located inside the groove 802, and a spring 807 is fixed between the bottom of the movable block 806 and the bottom of the groove 802.

[0024] The first cloth tape 9 and the second cloth tape 11 are fixed to both sides of the top of the support plate 4, respectively; a mother Velcro 10 is fixed to one side of the first cloth tape 9, and a child Velcro 12 is fixed to one side of the second cloth tape 11; the child Velcro 12 and the mother Velcro 10 are adhesively connected; through the adhesion between the child Velcro 12 and the mother Velcro 10, the first cloth tape 9 and the second cloth tape 11 can mount the patient's arm inside the support plate 4.

[0025] A soft pad 13 is fixed to the inner side of the support plate 4, and the support plate 4 is designed to be an arc-shaped structure. The design of the soft pad 13 ensures the comfort of the patient when taking the film.

[0026] Two support plates 4 are arranged on the rotating shaft 3, and the support plates 4 form a sliding structure with the rotating shaft 3 through the through hole 5. The design of the two support plates 4 can support the patient's arm at two locations, so that the position of the patient's arm where the X-ray is required can be located between the two support plates 4, ensuring that the support plates 4 will not hinder the X-ray of the patient's arm. Since the position of the support plates 4 can be adjusted on the rotating shaft 3, the position can be adjusted according to the patient's needs.

[0027] The limiting plate 7 and the limiting groove 6 form a sliding structure, and there are two limiting plates 7 and limiting grooves 6 symmetrically distributed about the central axis of the rotating shaft 3, ensuring that when the rotating shaft 3 rotates, the rotating shaft 3 can drive the supporting plate 4 to rotate through the limiting plate 7 and the limiting groove 6.

[0029] The servo motor 14 is electrically connected to the handheld controller, so that the doctor can control the operation of the servo motor 14 through the handheld controller.

[0030] Working principle: When using the angle-adjustable arm bracket, first pull the pull ring 805 downward, then the pull ring 805 drives the clamping rod 804 to move downward, and the clamping rod 804 drives the movable block 806 to move downward, so that the spring 807 is compressed, and the upper end of the clamping rod 804 is separated from the clamping groove 803, and then move the support plate 4 so that the support plate 4 moves on the rotating shaft 3. When the distance between the two support plates 4 is suitable for the patient to use, release the pull ring 805, and under the elastic force of the spring 807, the upper end of the clamping rod 804 is engaged with the clamping groove 803 at other positions on the rotating shaft 3, so that the position of the support plate 4 after moving is fixed;

[0031] Then, the patient's arm is placed on the two support plates 4, and the position of the patient's arm where the film needs to be taken is located between the two support plates 4. Then, the female Velcro 10 on the first cloth belt 9 and the sub Velcro 12 on the second cloth belt 11 are pasted together, so that the first cloth belt 9 and the second cloth belt 11 install the patient's arm inside the support plate 4;

[0032] When the patient needs to rotate his arm, the servo motor 14 is started with a handheld controller, and then the servo motor 14 drives the rotating shaft 3 to rotate, and then the rotating shaft 3 drives the two supporting plates 4 to rotate simultaneously through the limiting groove 6 and the limiting plate 7, and then the two supporting plates 4 drive the patient's arm to rotate, so that the patient's arm can be adjusted, so that the patient's arm can be filmed at multiple angles.
