2 Disclosed is a clutch-type control device for a cordless blind, comprising a 3 force-return mechanism and a braking mechanism. The braking mechanism includes an 4 outer housing having an engaging chuck, a shaft connecter having a gearshift lever, and a 5 clutch rotor with a gearshift pattern installed. Disposed on one end of the shaft 6 connecter are a plurality of engaging teeth. The axial distance between the gearshift 7 lever and the engaging chuck is fixed. The gearshift pattern has a blind-lowering 8 disengagement position, a blind-lifting disengagement position, and a blind-stopping 9 engagement position to position the gearshift lever so that the clutch rotor corresponding 10 to the shaft connecter may be operated with axial movement. The engaging teeth of the 11 clutch rotor may be engaged with or disengaged from the engaging chuck of the outer housing. Thereby, the stop height of cordless blind is accurately controlled and operation safety further is enhanced.
