The walking stick for the blind is safe and reliable, good in using effect, can protect the blind better.
Description
Technical field [0001] The invention relates to crutches for the blind. Background technique [0002] Blind cane is a simple device that assists the blind in walking. The existing blind cane can only perform a single auxiliary function. If there is an obstacle in front or water on the road, the blind cane cannot give an alarm in time and cannot adapt to it. Walking at night causes poor practical performance, low reliability, poor use effect, and inconvenience to the blind. Summary of the invention [0003] The technical problem to be solved by the present invention is that the existing crutch for the blind has poor practical performance, low reliability, and poor use effect, which brings inconvenience to the blind, thereby providing a crutch for the blind. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a crutch for the blind includes a crutch body, a control box connected to the crutch body, an i...
