At the same time, the self-locking principle of the worm wheel and the worm is utilized to fix the two linkage plates, so that the size of the skates can be quickly adjusted in a two-way linkage manner, and the movement of the shoe head is avoided, thereby improving safety.

[0020] 2. A connecting frame and a limit plate are provided. The limit plate contacts the linkage plate. When the linkage plate moves along the inner wall in the connecting frame, the two limit rods move along the slideway on the bottom inner wall of the connecting frame. At the same time, the limit plate squeezes and limits the linkage plate to prevent the linkage plate and the mounting plate from being separated from the connecting frame. The linkage plate can be limited when the code number is adjusted to prevent the linkage plate from being separated from the connecting frame, thereby improving practicality.

[0021] In summary, the utility model can quickly adjust the size of the skates in a two-way linkage manner, while preventing the toe from moving, thereby improving safety, and can limit the linkage plate when adjusting the size to prevent the linkage plate from detaching from the connection frame, thereby improving practicality.
