Description

Technical Field

[0001] The utility model relates to the field of crutches, in particular to a carbon fiber telescopic crutch. Background Art

[0002] There are many kinds of people who need to use crutches. In addition to the elderly who need crutches, there are also blind sticks and patients who need crutches for support. It is difficult for a single crutch to meet the needs of so many users. However, a specific analysis of these crutches shows that the actual difference between the crutches is not much. The difference mainly lies in the support head at the bottom, such as an ordinary flat-bottomed ordinary crutches head, a triangular support support head, or a wear-resistant wear-resistant head, etc. In addition, different people have different heights, and the height of the crutches also needs to be adapted to the height of the person. Therefore, there is a need for a carbon fiber retractable crutch with a replaceable crutches head, which is retractable and uses carbon fiber to make a high structural strength. Utility Model Content
