The shutter screen window has been pulled down. How can I get it back?

The control part of the roller shutter mechanism is a mechanism modulated by the mechanical principle that the passive axis can be controlled to rotate in one direction when the coil spring is twisted. As long as this mechanism is within the load range of the winding tube, the curtain will not slide down due to its own weight, and the curtain will rise or fall by manually operating the ball-pulling transmission part, so that the action is stable.

Roller shutter doors are suitable for general shutter doors, which are manually operated, and the height is generally 3-5 meters.
