摘要：
A variable speed transmission that changes the output speed of a power tool in response to an increase in torque. The transmission includes a first transmission portion, a second transmission portion, and an annular connector. The annular connector may move via a spring and a control mechanism between a first position and a second position to vary the power tool output between a first and a second speed.
