POWER AUXILIARY DEVICE FOR SMALL-SIZED ROLLER SHADE
The invention provides a power auxiliary device for a small-sized roller shade, including a fixed assembly and a transmission assembly. The fixed assembly includes a fixed seat and an upper cover. The transmission assembly includes a power portion with a gear, a speed-changing portion including a big speed-changing gear engaged with the gear and a small speed-changing gear, a transmission portion having a first transmission gear engaged with the small speed-changing gear and a second transmission gear disengaged with the first transmission gear and a reed piece, two ends of which are connected with the transmission portion separately. A length of the reed piece is shortened, and a crinkling volume of the reed piece is reduced through the speed-changing portion, so that the reed piece is applied to a smaller pipe diameter of a small-sized roller shade.
