A forearm supporting device is provided at one end. Pulling the side support 3 drives the connecting rod mechanism composed of the No. 1 connecting rod 21, the No. 2 connecting rod 22 and the No. 3 connecting rod 23 to move, so that the two groups of side supports 3 are away from the bottom support 1, and the distance between the two groups of side supports 3 and the bottom support 1 is increased, so that arms of any arm dimension can be inserted into them, and then the forearm is passed through the forearm supporting device, and the two groups of forearm supporting devices move synchronously with the corresponding side supports 3, and then the side supports 3 are pressed to shrink the two groups of side supports 3 and fit tightly with the arms, thereby playing a role of preliminary fixation.

[0025] The bottom support 1, the side support 3, the extension sleeve 4, the long rod 5 and the arm support 6 are all made by 3D printing.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the forearm support device includes an extension sleeve 4, a long rod 5 and an arm support 6, one end of the side support 3 is fixedly connected to the extension sleeve 4, one side of the extension sleeve 4 is screwed to the long rod 5, the other end of the long rod 5 is movably connected to the arm support 6, one side of the arm support 6 is provided with a slide groove 61, the outer side of the slide groove 61 is fixedly connected to a blocking bar 62, and the opening size of the blocking bar 62 is smaller than the size of the slide groove 61, and a connector 51 is provided on one side of the end of the long rod 5, the connector 51 includes a thin column 511 and a sliding head 512, and the sliding head 512 is connected to the arm support 6 through the slide groove 61 for sliding connection Then, the diameter of the slider 512 is larger than the diameter of the thin column 511, and the diameter of the thin column 511 is consistent with the opening size of the blocking bar 62. By rotating the long rod 5, the angle between the arm support 6 and the bottom support 1 can be changed to adapt to the forearm bending to different degrees. After the long rod 5 is rotated, the screws at the connection between the long rod 5 and the side support 3 are tightened to fix it, and the arm support 6 connected to the other end of the long rod 5 is rotated to a suitable angle, and the arm support 6 is pulled to make the slider 512 slide in the slide groove 61, so that the distance of the arm support 6 can be extended to allow the patient to adjust the support contact position according to his own condition.

[0027] like Figure 1 , Figure 3 and Figure 6 As shown, threaded holes are provided through the center of the thin column 511 and the slider 512, and the long rod 5 can be fixed to the arm support 6 by screws. After the arm support 6 is pulled to the specified position, the screws on the long rod 5 can be tightened to fix the long rod 5 to the arm support 6.
