Further, the support rod is fixedly connected with the tail ring in a welding mode.

Furthermore, the number of the rollers is two, and the central holes of the rollers are connected with the truss.

Furthermore, the upper end of the truss is fixedly connected with the motor in a welding mode.

Further, the transverse shaft and the transverse beam are fixedly connected through a crankshaft in a welding mode.

Adopt technical scheme after, bring following beneficial effect:

an automatic device that opens and shuts of (window) curtain, in the course of the work, the motor drives the gear rotation, and gear and rack toothing drives the tail ring and removes along the cross axle to drive all rings and remove, the range of opening and shutting of deciding the (window) curtain through the range of opening and shutting of a plurality of rings on the cross axle, the utility model discloses contrast prior art, simple structure, convenient operation, cost reduction improves the clean and tidy degree of (window) curtain simultaneously.
