The first scarfing rod ofthe brake sleeve and the second scarfing rod of the shaft housing are engaged with each other. 6
A power from the other end of the roller shade can drive the shaft housing to rotate so as to roll up the curtain sheet of the roller shade. The other end of the cord is dropped off, and the elastic force of the compression spring recovers and pushes the first scarfing rod of the brake sleeve to engage with the second scarfing rod of the shaft housing, so that the brake spring brakes and the clutch is pushed back inwards to the original position with the rotation portion, and the rotation portion is assisted to return to the original position by the restoring elastic force of the pull spring so as to assist the positioning of the curtain sheet after rolling up.
