Brake mechanism for curtain linkage system

A brake mechanism for curtain linkage system, which achieves a locking effect directed towards a counterforce from a curtain, and comprising a drive unit that actuates a motive effect on a linkage shaft through the brake mechanism, entire structural configuration is installed interior of a top rail of a curtain set, and is characterized in that the brake mechanism comprises a circular box, which is actuated by the drive unit;

• an interior of the box is adapted so as to form a circular slot, which provides for a shield-shaped rotor having a shear press surface to be moveably disposed therein;
• a periphery of the box is disposedly sheathed in an inner circumference of an immobile confining ring;
• center of the rotor outwardly connects to a linkage shaft;
• a rolling pin is configured relative between the shear press surface configured on the rotor and the inner circumference of the confining ring, moreover, the rolling pin is subjected to displacement and actuation within shearing slots configured in the box.
