Abstract
A workpiece holding device for a sewing machine is disclosed. When a workpiece holder is connected to a supporter, a connecting rod having a peripheral groove and extending from the workpiece holder is inserted into a horizontal hole formed in the supporter. In this case, the peripheral groove of the connecting rod is positioned to communicate with a vertical hole formed in the supporter. A piston rod slidably provided in the vertical hole is actuated by an air cylinder mechanism to be engaged with the peripheral groove of the connecting rod. In order to firmly engage the connecting rod and the piston rod, spring mechanism is also provided in addition to the air cylinder mechanism. Thus, the workpiece holder can be fixedly connected to the supporter, and easily detached from the supporter without tools and troublesome operations.
