Patent attributes
A step auto clay thrower consisting of a base, a stepping rod, a support, a throwing arm holder, a throwing arm and a mini motor is disclosed. When the stepping rod is depressed, the throwing arm is forced by a second spring to move a link and a first linking member in turning a shaft and a throwing arm forward for causing generation of a centrifugal force to throw a clay away from the throwing arm, and then a motor shaft of the mini motor is driven to rotate the shaft, thereby returning the throwing arm without any manual operation. In the time the throwing arm throws the clay and the throwing arm is returned by the mini motor, the mini motor does not need to overcome the force of the second spring so that the capacity of the mini motor can be minimized.
