When in a locked state, the fin is not easy to fall off, which can better help users improve their swimming skills.

[0004] When the user wears the diving shoes to dive, the deeper the diver goes, the greater the resistance of the water flow. The user can swim easily in the water by regularly swinging the fins with both feet. However, in order to increase the wearing comfort of the user, the connection structure between the foot cover and the fins is usually connected by soft materials. In addition, the resistance of the water flow causes a serious loss of the conductive force between the foot cover and the fins, making it extremely laborious to use. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a diving fin and a pressure relief method using the diving fin, which has the advantage of making the swing of the fin body consistent with the force of the foot cover body, thereby avoiding the loss of force of the foot between the connection between the fin body and the foot cover body.
