During rotation, one end of the elastic buckle 813 will disengage from the groove on the surface of the strap 6. After disengagement, the strap 6 can be pulled to adjust.

[0040] Working principle: When the ski binding is inserted, the wrench 71 is pulled and the wrench 71 rotates. When the wrench 71 rotates, it squeezes the sliding seat 732 to move backward. When the sliding seat 732 moves backward, the locking pin 737 slides to the deepest part of the inclined surface of the inclined surface groove 7321. Then, the locking pin 737 moves outward under the action of the pin rod, so that the end of the locking pin 737 located inside the bottom cover 2 is separated from the locking pin hole 31, thereby realizing the unlocking function on one side of the heel 3; on the other side, the rotation of the wrench 71 pulls the connecting rope 7 2. When the connecting rope 72 is pulled, the sliding seat 732 will be driven to move backward, and the unlocking function of the other side of the heel 3 will be realized in the same way. After the heel 3 is unlocked, the elastic force of the torsion spring 736 will drive the heel 3 to rotate, so that the heel 3 drives the backrest 4 to expand outward. When the heel 3 expands the backrest 4, the end of the heel 3 hinged with the strap 6 and the U-shaped cross bar 9 will be lifted, and when the strap 6 is lifted, one end of the top cover 5 will be lifted, so that the entire ski binding is in an open state, so that it is convenient for the user to quickly wear it.

[0041] After the user puts on the wearer's shoes, he or she will step on the U-shaped cross bar 9. When the U-shaped cross bar 9 is stepped on, the front strap 6 will move downward, and the movement of the strap 6 will drive the top cover 5 to retract. At the same time, the downward movement of the U-shaped cross bar 9 will also cause the heel 3 to rotate inward, thereby driving the backrest 4 to retract inward. When the U-shaped cross bar 9 is completely stepped on, the locking pin hole 31 on the surface of the heel 3 will be in the same straight line as the locking pin 737. At this time, the wrench 71 is loosened, and the reset spring 738 will push the sliding seat 732 to reset under the action of elastic force, and then the locking pin 737 will be pushed inward by the elastic force of the push spring 735 to make it stuck in the inside of the locking pin hole 31 to complete the locking, so that the self-locking work when worn can be completed without external force.

[0042] During the use of the ski binding, the length of the strap 6 is adjusted by the adjustment mechanism 8. When the adjustment mechanism 8 is implemented, by pulling the pull piece 816, the pull piece 816 will squeeze the elastic buckle 813, causing the elastic buckle 813 to rotate. During the rotation, one end of the elastic buckle 813 will disengage from the groove on the surface of the strap 6. After disengagement, the adjustment can be made by pulling the strap 6. Similarly, by pulling the fastening piece 823, the elastic buckle 813 will rotate along the support 821 under the action of the hinge pin 822. When the fastening piece 823 is disengaged from the groove on the surface of the strap 6, the adjustment can be made by pulling the strap 6. After the adjustment, the loose pull piece 816 and the fastening piece 823 will buckle the strap 6 under the action of the corresponding elastic force. When the top cover 5 and the snowshoes worn by the user are loose, the ski binding and the snowshoes worn by the user can be tightened by pulling the strap 6, so it is also convenient to adjust.
