Description

Technical Field

[0001] This utility model relates to the technical field of roller shutter door accessories, specifically, a switching handle for a clutch roller shutter door. Background Technology

[0002] Electric rolling shutters are typically equipped with a clutch converter, which allows them to switch between electric and manual operation. The clutch converter is usually equipped with a steel wire rope, which is pulled to engage or disengage the clutch, thereby enabling the electric rolling shutter to switch between electric and manual operation and preventing the electric rolling shutter from becoming unusable after a power outage.

[0003] In existing electric roller shutters, the steel wire rope is installed inside the wall, and a lock box with a lock cylinder is installed on the wall. When switching, the lock box is opened with a key, and the steel wire rope is pulled out manually. However, because the steel wire rope is relatively thin, a certain amount of force is required when pulling it, which can easily cause pain in the palm. Moreover, when switching back to electric, the steel wire rope needs to be slowly pushed into the lock box, which is a rather troublesome process. Utility Model Content
