Cloth-press foot driving structure of sewing machine

The utility model discloses a drive construction of cloth compressor for sewing machine, which is positioned on a sewing machine to drive the linkage of the sewing machine so that the cloth compressor at one end of the linkage compresses the cloth or lifts the compressor, comprising a set of fixing supports arranged on the sewing machine and actuator arranged on the fixing supports, which is characterized in that the actuator has a pusher arm used to push the driving member of the linkage with cloth compressor, thus driving the linkage for cloth compression and compressor lifting via the cloth compressor, wherein during the compressor lifting process, the axis of the pusher arm is perpendicular to that of the driving member and then, the backward force transferred by the driving member is just coaxial to the axis of the pusher arm and a positive force thereof so that the pusher arm and actuator will not be damaged resulting from shear stress, thus extending the service life of the actuator.
