Hand and foot free swimming power device

The invention relates to a hand and foot free swimming power device which effectively solves the problem that a user is inconvenient to move after going ashore by arranging two resistance plates. By arranging the fixed support and the two transverse rods at the bottom of the fixed support, a user can conveniently and selectively install the resistance plate and the movable plate at the tiptoe position or the heel position according to swimming postures, and more labor is saved during swimming. By arranging the first valve bag and the second valve bag, when a user kicks water with two feet and strokes water with two hands, the first valve bag and the second valve bag are driven to move together, then water enters the first valve bag and the second valve bag, and due to the fact that the water is static and is matched with the first valve bag and the second valve bag, resistance is provided; directional power is provided for the human body; meanwhile, after water in the first valve bag and the second valve expa
