[0002] Labor protection shoes, also known as safety shoes or protective shoes, are a type of shoes that provide safety protection for the feet and are mainly used to protect workers from foreseeable injuries in a specific working environment;

[0003] For example, a safety protection type puncture-proof labor insurance shoe with publication number CN219438309U adopts the mutual cooperation between the rubber outsole, the rubber midsole, the slot and the metal thin steel sheet. The slot is arranged in the sole plate, and the slot is evenly distributed along the extension direction of the rubber outsole. The metal thin steel sheet in the slot can effectively play an anti-puncture role. There is a spacing between two adjacent metal thin steel sheets, so that the rubber outsole can be bent within a certain range, which improves the flexibility of the rubber outsole and makes it more comfortable to wear. Through the mutual cooperation between the first steel wire mesh, the second steel wire mesh, the inner insole, the inner insole of the shoe and the insole slot, even if a sharp object passes through two adjacent metal thin steel sheets, the first steel wire mesh and the second steel wire mesh can effectively block the sharp object, thereby greatly improving the anti-puncture function of the sole plate, and the second steel wire mesh can be taken out from the insole, which is convenient for replacing the second steel wire mesh.

[0004] When using the above technical solution, the user puts on the safety shoes and manually ties the shoelaces, and utilizes the first and second steel wire braided meshes and the metal thin steel sheet provided in the sole plate to improve the anti-puncture function of the sole plate. However, the user needs to tighten the shoelaces every time he puts on and takes off the safety shoes, which is troublesome. Moreover, if the shoelaces are tied loosely, they will become loose when worn, causing the safety shoes to fall off. However, the existing safety shoes lack the function of tying the shoelaces, which makes it inconvenient for the user to put on and take off the safety shoes.

[0005] Therefore, we proposed that labor protection shoes with shoelace tightening function can solve the above problems well. Utility Model Content
