Abstract
The invention discloses a window curtain one-direction control device with the positioning function and a window curtain of the device. The device is characterized in that when a transmission shaft actively rotates, a first bulge props one propping part of a rotating spring to send a force from inside to the outside to enable a rotating twisting part of the rotating spring to be reduced in the circumferential direction, and the rotating spring rotates to drive a first rotating part to rotate so as to drive a second rotating part to rotate; when the first rotating part actively rotates, a stop gap of the first rotating part props one propping part of the rotating spring to send a force from outside to inside to enable the rotating twisting part of the rotating spring to be amplified in the circumferential direction, and then the rotating spring cannot rotate. Compared with the prior art, the window curtain one-direction control device with the positioning function and the window curtain of the device have the advantages that a controller provides a good non-returning effect to control the window curtain from falling due to the effect of the gravity, and therefore, the window curtain can be accurately positioned during being raised or fallen.
