Furthermore, one end of each of the two horizontal telescopic pieces 10 is rotatably connected with the same arc-shaped rod 12, a guide wheel 13 is arranged on each arc-shaped rod 12, and one end of each of the second traction ropes 8 is connected with the hand crank 5 through the guide wheel 13.

Because the arc rod 12 is rotatably connected to one end of the two horizontal telescopic pieces 10, when the traction angle needs to be adjusted, the arc rod 12 only needs to be rotated by a certain angle, so that the position height of the guide wheel 13 on the arc rod 12 is changed, and the proper traction angle is adjusted.

Further, the traction frame body 1 further comprises a plurality of telescopic supporting rods 17, the plurality of supporting rods 17 are used for supporting the same sliding rail 3, and two ends of each supporting rod 17 are detachably connected with the vertical telescopic pieces 11.

Further, both ends of each support rod 17 are provided with circular grooves (not shown in the drawings), and each vertical telescopic member 11 is provided with protrusions (not shown in the drawings) which can be matched with the circular grooves. Because in this application, bracing piece 17 has flexible function for bracing piece 17 when expanding and stretching out, its both ends all can cooperate with the arch on the perpendicular extensible member 11, make its cover locate protruding outside.

Further, the lower terminal surface of slide rail 3 is provided with arc wall 18, and the number of arc wall 18 is a plurality of and can cooperate with a plurality of bracing piece 17 one by one.

The slide rail 3 is clamped on the support rods 17 by the arc grooves 18 at the lower end to prevent the slide rail 3 from moving along the length direction. Specifically, the method comprises the following steps: because the foot support 2 is arranged above the slide rail 3, and the traction rope pulls the foot support 2 to move in the length direction of the slide rail 3, friction force exists between the foot support 2 and the slide rail 3, and the slide rail 3 can be synchronously driven to move in the length direction. And the arc-shaped groove 18 arranged on the lower end surface of the sliding rail 3 is matched with a plurality of supporting rods 17, so that the sliding rail 3 can be limited to move in the length direction.

Further, the shape of the slide rail 3 is arranged in a convex shape.

Furthermore, the foot support 2 comprises a metal support 19 which is matched with the arc shape of the legs of the human body, a gap 20 which can be passed by the legs of the human body is arranged above the metal support 19, and a plurality of pulleys 4 are arranged below the metal support 19 at intervals. The metal support 19 is provided with a bandage 21 at the gap 20, and the bandage 21 can bind the leg of the human body with the metal support 19. The end of the metal holder 19 facing the guide wheel 13 is provided with a hook 22 that can cooperate with the first traction rope 7.

Further, the inner side of the metal support 19 is provided with an inner lining 23 which can be attached to the leg of the human body. By arranging the inner lining 23, the comfort degree of the foot support 2 matched with the legs of the human body can be increased.

Further, the present application provides another embodiment, that is, a magic tape for binding the leg of the human body is disposed at the notch 20, and the magic tape may be disposed on the metal support 19 or the lining 23.

Further, the horizontal telescopic member 10, the vertical telescopic member 11 and the support rod 17 have a structure similar to that of the telescopic rod of the conventional folding umbrella. All of them are used to realize the expansion and the accommodation of a rod-shaped object in the axial direction, which will not be described in detail herein.

Through foretell flexible design to make this application draw gear be convenient for dismouting, the effect of accomodating.

Example two:

the difference from the first embodiment is that: as shown in fig. 1 and 5, the same pad 24 is fitted between the two horizontal telescopic members 10, the pad 24 includes an upper layer of varnished cloth 25 and a lower layer of magic tape 26, the cross-sectional area of the upper layer of varnished cloth 25 is smaller than that of the lower layer of magic tape 26, and two ends of the lower layer of magic tape 26 are fitted with the two horizontal telescopic members 10 respectively and are bound.

The upper-layer varnished cloth 25 is made of polytetrafluoroethylene glass fiber cloth, is made of high-performance glass fiber cloth impregnated with suspended polytetrafluoroethylene (commonly known as plastic king) emulsion, is non-sticky, is not easy to adhere to any substance, has low friction coefficient, and is the best choice for oil-free self-lubrication. In the application, the friction force between the limbs and the liner can be greatly reduced, the traction friction force is reduced, and the traction efficiency is improved.
