The second circular rod body 124 drives the semicircular through hole 22 to rotate to one side of the semicircular blocking block 125, which is used to seal the semicircular through hole 22 and the L-shaped through hole 20, thereby limiting the position of the movable support block 11, and supporting the patient's arm for a long time.

[0053] When it is necessary to replenish water in the movable through cavity 7, the doctor only needs to hold the square rotating rod 121 and rotate it. The square rotating rod 121 drives the first circular rod body 123 and the second circular rod body 124 to rotate. The second circular rod body 124 drives the semicircular through hole 22 to rotate out from the semicircular blocking block 125 to connect the semicircular through hole 22 with the L-shaped through hole 20. After that, the relevant personnel hold the square rotating rod 121 and drive the two L-shaped moving rods 120 to move. The two L-shaped moving rods 120 drive the movable sealing plug 122 to move in the liquid storage cavity 6, thereby squeezing the water in the liquid storage cavity 6 and The water is transmitted to the movable cavity 7 through the first circular through hole 9, the L-shaped through hole 20, the semicircular through hole 22, the second circular through hole 21, the three-way pipe 126, the two bellows 127 and the two second tube bodies 128, so that the water in the movable cavity 7 is pressurized to push the movable support block 11 to move, and all the water in the liquid storage chamber 6 is squeezed into the movable cavity 7. After that, the doctor connects the external water injection pipe with the second tube body 128, and opens the second switch valve 129 and the first switch valve 29 to facilitate the transmission of external water to the movable cavity 7. If liquid flows out of the first tube body 28, it indicates that the movable cavity 7 is full of water.
