Description

Technical Field

[0002] Ladders are popular among people as an indispensable tool in people's lives. Ladders are mainly used for climbing and provide convenient conditions for people to carry out production and life.

[0003] The existing ladder is usually an upright structure. When in use, one end of the ladder needs to be placed on the ground and the other end needs to be leaned against the wall. When climbing, one person needs to hold the ladder with one hand while the other person climbs up. If the person's handhold on the ladder is not stable, the bottom of the ladder is likely to slip between the ground, posing a great safety hazard. In addition, the height of the existing ladder after placement is fixed, and its climbing height range is small, and its use is relatively limited. For this reason, we propose a free-hand anti-slip insulating ladder. Utility Model Content
