The rear surface of the triangular block 43 is provided with a protrusion, and the front surface of the movable plate 44 is provided with a groove, and the protrusion slides in the groove.

[0038] Working principle: When using this device, first pass the strap 2 through the hole 101, then put the I-shaped plate 31 around the hole 101 and put it on the lower surface of the hand support plate 1, and tighten the locking bolt 32 to complete the fixation of the I-shaped plate 31 and the hand support plate 1, then place the I-shaped plate 31 and the hand support plate 1 on the support table, and pass the strap 2 around the support table and tighten it to achieve the fixation of the hand support plate 1 and the I-shaped plate 31, and then judge whether the support plate 39 needs to be unfolded according to the length of the patient's arm. If it needs to be unfolded, pull the handle 313 forward to drive the support plate 39, the block 311 and the baffle 312 to move forward. When the support plate 39 moves forward The slider 37, the protrusion 38 and the round rod 36 will be pulled forward, and the protrusion 38 will move along the track of the slide groove 301. Since the slide groove 301 is inclined, the round rod 36, the protrusion 38 and the support plate 39 will gradually rise while moving forward. When the round rod 36 moves forward and upward, it will pull the compression spring 35 to generate a reaction force, and will drive the hollow tube 34 and the slider 33 to move upward. When the protrusion 38 moves to the front end of the slide groove 301, the handle 313 will be slowly moved backward to plug the block 311 into the slot 302. Under the influence of the tension of the compression spring 35, the block 311 will be tightly plugged into the slot 302.

[0039] Then place the support plate 41 between the two sets of baffles 312, and turn the positioning bolt 42 to move it backward. The positioning bolt 42 will drive the triangular block 43 to move backward to squeeze the inclined surface of the movable plate 44. The two sets of movable plates 44 will open and remain tightly fixed to the baffles 312. Then lay the cotton pad, and the patient can put his arm on the cotton pad. At this time, the support plate 41 will be aligned with the patient's wrist, adapting to the patient's physiological curve to ensure that the patient does not feel discomfort.

[0040] If there is no need to unfold the support plate 39, just turn the positioning bolts 42 at the appropriate position on the hand support plate 1 to spread the two sets of movable plates 44 apart, so that the support plate 41 is fixed between the hand support plates 1 to maintain stability. When the support plate 41 is fixed, its bottom surface and the upper surface of the hand support plate 1 need to be in contact with the upper surface of the support plate 39 to ensure the stability of the support height.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
