- an axle member having an axle and a connection section extending in a direction opposite to the axle;
- a first rotary member having a first rotary section to couple with the axle, the first rotary section being an arched plate bent to form a first opening;
- and
- an arched second rotary member made of a plate having a second rotary section encasing the first opening of the first rotary section, the second rotary section having a second opening opposing the first opening, the first rotary section and the second rotary section being extended respectively to form a first fastening section and a second fastening section corresponding to each other and being located transversely on the center axis of the axle member;
- wherein the first rotary member and the second rotary member provide respectively a friction force required for turning in different directions, and the rotary members form an opening or a closing condition relative to the axle member depending on the direction of forces being applied.
