One end of two straps is connected to the groove seat, and the other ends of the two straps are adhered to each other through a magic tape. A driving structure for driving the vertical screw rod to rotate is arranged on the top of the base. When the vertical screw rod is driven to rotate by the driving structure, the movable seat drives the movable seat to adjust its position along the vertical rod under the rotation of the vertical screw rod and the sliding on the vertical rod.

[0006] Preferably, the driving structure includes a protective cover arranged on the top of the base. A second bearing is fixed on the protective cover. The inner ring of the second bearing is fixed on a horizontal screw rod. The other end of the horizontal screw rod is located outside the protective cover and is connected to a crank. One end of the horizontal screw rod extends into the protective cover and is connected to a vertical bevel gear. The vertical bevel gear is meshed with a horizontal bevel gear fixed on the vertical screw rod.

[0007] Preferably, the top of the protective cover is provided with a first through hole and a second through hole facilitating the extension of the horizontal screw rod and the top end of the vertical rod.

[0008] Preferably, a limiting block is provided at the top end of the vertical rod.

[0009] Preferably, four self-locking universal wheels are provided at the bottom of the base.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] This device fixes the patient's limb through the groove seat and the strap. When the driving structure drives the vertical screw rod to rotate, under the rotation of the vertical screw rod and the sliding on the vertical rod, the movable seat drives the movable seat to adjust the height along the vertical rod. The groove seat adjusts the angle along the hinge part through the connecting plate and is fixed by the locking screw rod, which is applicable to different patients, making the device more convenient and stable in actual use.
