  • the brake elastic member (246) is tightly fitted on the tail seat (3) again, and the adjusted auxiliary elastic member (243) can be retained to maintain the auxiliary elastic potential energy.
  • the auxiliary elastic member (243) will release the auxiliary elastic potential energy, so that the user can roll up the curtain fabric (A) with less force. Since the brake elastic member (246) is similar to the first elastic member (13) shown in FIG. 6 , it is only briefly described herein.
  • the control device (1) when the curtain fabric (A) is in urgent need to be pulled down for hiding, the user only needs to energize the solenoid valve (12) by means of a remote control or a switch to disengage the front cap (15) from the engaging portion of the reeling mechanism (11), that is, the front cap (15) is disengaged from the inner cylinder (112) and the outer cylinder (113), thereby lowering the curtain fabric ( A). There is no need for the user to approach the door/window where the curtain fabric (A) is located for operating the reeling wheel (111), reducing the risk of being discovered. After the curtain fabric (A) is lowered, the curtain fabric (A) can be restrained at an appropriate height by the limiting mechanism (23), preventing the strong impact force from damaging the roller blind when the curtain fabric (A) is lowered.
  • the operations of the limiting mechanism (23) and the adjustment mechanism (24) are designed at the same side, which is convenient for the user to adjust and operate.
