The retraction speed of the curtain body can be adjusted according to the different resilience force of the torsion spring. The rolling shutter adjusting bracket at one end rotates the adjusting wheel along the torsion spring twisting direction, then releases the rotating adjusting wheel, and the shutter body is lifted. When the curtain body is retracted, the larger the torsion amplitude of the torsion spring is, the larger the resilience force of the torsion spring is, the released energy enables the winding drum to rotate, and the retraction speed is also larger. The speed of the roller shutter is adjusted through the process.
On the other hand, the other rotation direction of the adjusting wheel is always in a contracted state, when the adjusting wheel is rotated along the direction, the driving rod is directly driven to rotate, and the end is additionally provided with a limiter which can rotate the adjusting wheel to stop at a set position when the curtain body is retracted through the cooperation of the two.
