40 respectively with bottom plate 1 one side, ring 41 one side fixed connection, it slides to drive fixture block 31 through the slip of three hornblocks 32, make fixture block and first gear 4 mesh and restrict axis of rotation 2, can prevent to adjust the altitude change that finishes.

The working principle is as follows: when the patient leg needs to be supported and limited, the leg needs to be fixed firstly, the strip-shaped plate 36 is manually slid, the sliding of the strip-shaped plate 36 is released and the clamping of the notch 35 is released, so that the sliding limitation of the sliding block 34 is released, the sliding block 34 slides out of the top of the groove plate 24, after all four parts slide out, the two legs of the patient are respectively put into the limiting mould 22, the fixing belt 23 is tightened for fixing, after the patient leg is put into the limiting mould 22, the strip-shaped plate 36 is slid, the sliding block 34 is aligned with the top of the groove plate 24, the sliding block 34 is slid downwards after alignment, the sliding of the sliding block 34 drives one end of the fixing belt 23 to move, so that the leg is fixed, after the fixing is finished, the sliding of the strip-shaped plate 36 is released, under the elasticity of the tension spring 37, the strip-shaped plate 36 slides and is clamped into the corresponding notch 35, the sliding block 34 is fixed, then the height of the supporting and limiting of the two legs is adjusted according to the height required by the treatment, the limitation of the rotating shaft 2 is relieved by pulling the ring 41, the movement of the ring 41 drives the pull rod 33 to slide, the sliding of the pull rod 33 drives the triangular block 32 to slide, the sliding of the triangular block 32 drives the sliding of the fixture block 31, the sliding of the fixture block 31 is relieved from the clamping of the first gear 4, thereby the limitation of the rotating shaft 2 is relieved, after the limitation of the rotating shaft 2 is relieved, the hand wheel 7 is manually rotated, the rotation of the hand wheel 7 drives the shaft lever 5 to rotate, the rotation of the shaft lever 5 drives the second gear 6 to rotate, the rotation of the second gear 6 drives the third gear 8 to rotate, the rotation of the third gear 8 drives the two rotating levers 12 to rotate, the rotation of the two rotating levers 12 respectively drives the sliding plate 10 and the hollow plate 25 to slide through the connecting rod 13, the sliding of the sliding plate 10 and the plate 25 drives the rotating roller 14 to move, the movement of the rotating roller 14 drives the mounting plate 15 to move, the mounting plate 15 moves, so that the adjustment of the supporting and limiting height of the two legs is realized, when the proper height is adjusted, the rotation of the hand wheel 7 is stopped, the pulling of the ring 41 is released, under the restoring force of the spring 40, the pull rod 33 slides to drive the fixture block 31 to slide, so that the fixture block 31 is clamped with the first gear 4 again to limit the rotating shaft 2, after the height adjustment is finished, the leg supporting and limiting angle is adjusted according to the treatment requirement, the rack plate 27 is driven to slide by the rotation of the second threaded rod 28 through the manual rotation, the sliding of the rack plate 27 drives the fourth gear 26 to rotate, the rotation of the fourth gear 26 drives the rotating roller 14 to rotate, the rotation of the rotating roller 14 drives the mounting plate 15 to rotate, the rotation of the mounting plate 15 drives the limiting mold 22 to rotate, and the rotation of the limiting mold 22 realizes the adjustment of the leg supporting and limiting angle, when the second threaded rod 28 is rotated, the adjusting angle is determined through the angle dial 29 and the pointer 30, after the proper angle is adjusted, the rotation of the second threaded rod 28 is stopped, after the angle is adjusted, when the distance between two legs needs to be adjusted for more convenient treatment, the adjusting plate 18 can be manually shifted to adjust, the rotation of the adjusting plate 18 drives the two-way internal threaded pipe 17 to rotate, the rotation of the two-way internal threaded pipe 17 drives the two first threaded rods 16 to move oppositely, the opposite movement of the two first threaded rods 16 drives the two connecting plates 19 to slide oppositely, the opposite sliding of the two connecting plates 19 drives the two limiting molds 22 to slide oppositely, the opposite sliding of the two limiting molds 22 realizes the adjustment of the distance between the two legs, and after the proper distance is adjusted, the shifting of the adjusting plate 18 is stopped.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
