A walking stick belongs to the field of civil articles. The walking problem of the blind is solved. A plurality of transmission steel wires 1 are arranged in the walking stick, one ends of the transmission steel wires are connected with a sensing contact 2, the other ends are connected with a lever at the bottommost end of the walking stick, and one end of the lever is connected with a small ball3. The walking stick is for civil use.
Description
technical field [0001] A crutch belongs to the field of civilian products. Background technique [0002] Existing blind people can't know whether to go uphill or downhill with the stick used. Contents of the invention [0003] A crutch is invented here, so that the blind can know whether to go uphill or downhill during use. [0004] This invention is such that there are many transmission steel wires 1 in the crutch, one end of the transmission steel wire is connected with the sensing contact 2, the other end is connected with the lever at the bottom of the crutch, and one end of the lever is connected with the small ball 3. When in use, when the ball is going downhill, it falls under the action of gravity, thereby pulling the steel wire down, so that the contact point drops, and the blind person knows that it is going downhill. When going uphill, the ball rises, and the lever rises, thereby driving The steel wire also rises, so it rises at the touch point, and the blind ...
