Background

The rolling curtain is one of window decoration products, and is a curtain product which is formed by rolling curtain cloth on a scroll and driving the scroll to rotate by adopting a pull rope or a motor and the like so as to enable the curtain cloth to ascend or descend. Most of roller blinds are arranged in the inner frame of the window, and two ends of the roller are abutted with the inner frame of the window or erected on a bracket fixedly connected with the inner frame of the window. This means that the dimensions of the spool and the window inner frame need to be matched more precisely. However, the actual window frame size and the design size have certain deviation, although the window frame size and the design size can be customized according to the size after measurement, the finished rolling curtain with uniform size is more stable in product control, the control cost of manufacturers is facilitated, and in addition, the requirement on installation is met, and the length of the winding shaft can be adjusted within a certain range.

In the prior art, the reel typically includes a shaft body and a tail plug plugged at the end of the shaft body, and the length adjustment is typically performed by adjusting the length of the tail plug. However, the existing tail plug has more common parts, needs small parts such as springs with low durability or easy loss, causes various after-sales problems, and still needs improvement.
