The working principle of the invention is as follows:

when the snowshoe 6 is connected with the fixer, the sole of the snowshoe 6 enters the bottom plate 3 to form a containing cavity of the snowshoe 6 together with the U-shaped structure through treading or pressing down and the like, the second clamping groove 211 on the front fixed matching part 21 is matched with the hook-shaped extension part 315, then the rear end of the fixed plate 2 is pressed down, so that the fixed plate 2 is in a horizontal state, the fixed plate 2 drives the second clamping groove 211 to rotate for a certain angle when pressed down, the second clamping groove 211 is clamped with the hook-shaped extension part 315 in the rotating process, so that the front fixed part 31 is clamped with the front fixed matching part 21, the hook-shaped extension part 315 extends into the second clamping groove 211 to be clamped with the second clamping groove 211, meanwhile, the matching blocks 221 on two sides of the fixed plate 2 slide down along the matching grooves 511 on the side walls on two sides, and through a gap between the limiting part 414 and the side wall of the first clamping groove 51, and the extension part 222 at the bottom of the matching block 221 can extrude and limit in the process of downward movement through a gap between the limiting part 414 and the side wall of the first clamping groove 51 The positioning part 414 enables the limiting part 414 to rotate around the first rotating shaft 412, when the extending part 222 moves downwards to the lower part of the limiting part 414, the extending part 222 is clamped between the limiting part 414 and the bottom of the first clamping groove 51, and at this time, the matching block 221 is clamped and cannot move up and down, so that the fixing plate 2 is clamped, the rear fixing matching part 22 is clamped with the rear fixing part 41 fixed on the bottom plate 3, and at this time, the connecting points of the fixing plate and the bottom plate are combined with each other to form three-point distribution positioning, so that the fixing plate 2 is ensured to be well connected with the bottom plate 3, and the fixer is used for buckling the snowshoe 6 from two sides of the heel and three points at the front end of the sole;

when the snowshoe 6 is separated from the fixer, the loosening push plate 42 is pushed upwards, the loosening adjusting end 423 of the loosening push plate 42 pushes the adjusting part 416 of the rear clamping block 411, so that the ball in the marble screw 415 mounted at the upper end of the rear clamping block 411 is clamped at the edge of the opening 512, the gap between the limiting part 414 and the side wall of the first clamping groove 51 is increased to the gap between the extending part 222 at the bottom of the matching block 221 and can penetrate out from the gap between the limiting part 414 and the side wall of the first clamping groove 51, the fixing plate 2 is pulled upwards when the snowshoe 6 is detached, the fixing plate 2 can be separated from the fixing frame 1, and therefore the snowshoe 6 is separated from the snowboard.
