Referring to fig. 7, the pinching part 9 includes two transverse sliding rods 901, pinching blocks 902 and a pulling rope 903, the two transverse sliding rods 901 are fixed on the right side of a connecting plate between the two square sliding barrels 301 through three fixing blocks, and are used for guiding the pinching blocks 902 through the arrangement of the transverse sliding rods 901, and two springs are sleeved on the outer portion of each transverse sliding rod 901 in a front-back symmetrical manner, so that elasticity is provided between the two pinching blocks 902; two horizontal slide bar 901 outsides are two symmetrical form sliding connection in front and back and hold between two pieces 902, and two hold between two pieces 902 back of the body all are fixed with one and pull the rope 903 for to two pull rod 403 pulling operations, two pull the rope 903 other ends and fix respectively at two pull rod 403 back of the body ends, when two hold between the bodies 902 and be in the state of holding between the fingers, as shown in figure 7, two grafting sliders 402 slide to the back of the body direction in two grafting sliding shells 401 inside respectively, thereby make the spliced pole on two grafting sliders 402 can be simultaneously from preventing falling 3 both sides of portion of falling and adjusting the inside extraction of jack 303.

In another embodiment, two pulleys are slidably connected to a bent portion of the outer portion of each pulling rope 903, and are mounted on the outer portion of the upper end of the square sliding barrel 301 through a bracket, so that the pulling rope 903 can obtain an effective guiding effect when the pulling rod 403 is pulled.

When in use: a skier wears the ski boot 5 on the foot, then clamps the ski boot 5 on the fixing part 2, during clamping, the front end of the ski boot 5 is inserted into the fixing shoe cover 202, then the clamping screw 204 is rotated to drive the movable clamping block 203 to slide forwards under the action of threads, then the ski boot 5 boot and the rear side rectangular insertion block are clamped through the rectangular groove at the front end of the movable clamping block 203, then the pulling column on the pulling plate 803 is taken down from the L-shaped limiting block 804 to enable the pulling column on the pulling plate 803 to lose the limiting function, then under the action of a spring, the limiting slide block 802 drives the limiting insertion rod 805 to move downwards, so that the limiting insertion rod 805 is inserted into the rear side rectangular insertion block of the ski boot 5 boot and the rear side of the ski boot 5 boot is limited;

novice will take place the side when falling down the phenomenon at the skiing in-process, the contact of skier's health slope back with prevent falling 3 upper end sponge lag 302 outer peripheral face of portion, then make and prevent falling 3 upper ends atress of portion, then prevent falling 3 with this thigh power transmission to two square slide tube 301 on, then two square slide tube 301 rethread two supporting parts 7 with this thigh power transmission to support on the slide 6, then through supporting 6 bottom face and snowfield contact back, will support two supporting parts 7 and live.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
