Regarding.

2. Description of the Related Art In recent years, shoe laces are generally used as one of the means for tightening shoes to fit the user's feet in a wide variety of shoes such as athletic shoes. Such shoelaces are tied by passing through a number of through-holes arranged in the upper and ankle parts of the shoe, and the remaining shoelaces are tied by tying both ends to form a knot. As the tying becomes finalized, there has been the inconvenience of tying the laces to the shoe or having to tighten or untie the shoe knots when untying them.

In addition, since most of the laces for ordinary shoes are made of synthetic resin thread, they have the property of slipping on each other, so it is difficult to perform vigorous exercise or wear shoes for a long time while tying the laces. If you do, the shoelaces will untie or become loose, which not only looks bad, but if the untied shoelaces come in contact with the floor, the shoelaces will become contaminated, or if you step on the untied shoelaces, you will fall. However, there is a problem that a safety accident may occur.

In order to solve these problems, a 'shoe lace tightening device' disclosed in Korean Utility Model Registration No. 20-0440027 and Korean Patent Registration No. 10-0904132 has been developed.

The shoelace tightening device secures a space between the movable gear portion and the fixed gear portion by pressing a pressing rod or a protruding rod of the shoelace tightening device, and secures the shoelace to a proper position from the inside. When the pressure is released, the movable gear portion and the fixed gear portion are engaged with the shoelace by the elastic force of the spring or elastic bar, which is an elastic member, thereby fixing the shoelace and tying the knot. To prevent loosening by simply fixing shoelaces without tying them.

However, in the above-described prior art, first, during the pressing operation for securing the space between the movable gear portion and the fixed gear portion, a horizontal gap is provided between the movable gear portion and the fixed gear portion for separation. Pressing must be performed, but since the pressing rod and the protruding rod to be gripped by the fingers are formed on the upper part of the movable gear part, pressing the pressing rod and the protruding rod with the finger will not perform accurate horizontal pressing, but will cause an oblique direction. Pressing is now performed, and as a result, a large amount of force is required for the pressing operation, which poses the problem that not only is the pressing operation difficult, but there is a possibility that the finger may be overworked.
