Each shoe comprises a shoe body and a tightening device, wherein the tightening device comprises a fixed seat, a sliding table and a clamping block; the fixed seat is arranged on the shoe body; a sliding groove is formed in the upper surface of the fixed seat; through holes are symmetrically formed in positions, close to the upper surface of the fixed seat, on two side walls of the sliding groove; an adjusting groove, communicated with the sliding groove, is formed in one side face of the fixed seat; a rotary shaft is fixed in the adjusting groove; the sliding table is arranged in the sliding groove in a sliding manner; a lock catch is arranged at the position, corresponding to the adjusting groove, on the sliding table; the clamping block rotatably sleeves the rotary shaft; a hasp is arranged at one end, corresponding to the lock catch, on the clamping block; the hasp can be clamped on the lock catch; a convex block, stretching out of the adjusting groove, is arranged above the other end of the clamping block; a spring is arranged at the position, close to the clamping block, under the convex block; the two ends of the spring are fixedly connected with the convex block and the adjusting groove respectively. With the adoption of the manner above, the shoes can be firmly fixed on feet and are easy to wear and take off.

Description

technical field [0001] The invention relates to the field of shoes, in particular to a shoe that can automatically loosen and tie shoelaces. Background technique [0002] At present, shoes on the market generally have three ways of tightening. One is the shoelace type. Although this method can securely fasten the shoelaces, it needs to be used by a person with full operational ability, which is inconvenient to operate and has certain safety hazards; it is also a big problem for preschool children. The second is the sticky type. This method not only effectively solves the difficult problem of shoelace shoes, but also avoids the safety hazards in the use of shoelace shoes. However, it is easy to fail and the service life Shorter, not able to securely fasten the shoe. The third is the elastic belt type. This method can effectively solve the difficult problem of shoelace shoes, and can also avoid the safety hazards in the use of shoelace shoes. However, the degree of tightness...

One is the shoelace type. Although this method can securely fasten the shoelaces, it needs to be used by a person with full operational ability. It is inconvenient to operate and has certain safety hazards; it is also a big problem for preschool children.

The second is the sticky type. This method not only effectively solves the difficult problem of shoelace shoes, but also avoids the safety hazards in the use of shoelace shoes. However, it is easy to fail and the service life Short, not able to securely fasten the shoe

The third is the elastic belt type. This method can effectively solve the difficult problem of shoelace shoes, and can also avoid the safety hazards in the use of shoelace shoes. However, the degree of tightness is limited and the shoes cannot be Fastened to the foot and is easily damaged with a short service life
