Abstract
A human-powered underwater propulsor for user's moving in water mainly has a power generating module provided within a receiving space inside a waterproof airbag, and the power generating module is coupled to a propulsion unit. The receiving space is formed with an opening end provided with a waterproof ring to be worn by user in such a manner that the receiving space is hermetically sealed to prevent water from entering the receiving space during diving. When user pedals by stepping on two pedals of the power generating module, the power generating module is actuated to cause the flapping of the propulsion unit. Hence, the human-powered underwater propulsor allows user to exercise his feet in the air to reduce drag in diving so that user can moves more easily in the water.

A human-powered underwater propulsor, comprising
- a waterproof airbag having a receiving space provided internally, an open end being formed on said receiving space and a waterproof ring being provided on said open end in such a manner that said receiving space is hermetically sealed after user wears the waterproof airbag;
- furthermore, a propulsion unit being provided on the other end of said waterproof airbag;
- a power generating module which has a gear box being provided in said receiving space, said power generating module having a gear box with two cranks being connected respectively on both sides thereof, each end of the two cranks having a pedal assembled thereon for pedaling by user;
- one end of the gear box being connected with a swing rod which is connected to the propulsion unit;
- the other end of the gear box being assembled with a saddle for user to sit thereon;
- after user wears said waterproof airbag, the buttock of the user sits on the saddle and user's feet pedal to actuate said gear box so that said swing rod is actuated to drive the propulsion unit to flap.
