Patent ID: 8384968

Claim:
A transmission mechanism for switching output powers, the transmission mechanism comprising: a first transmission gear; a second transmission gear; a first power-connecting member coaxially disposed between the first transmission gear and the second transmission gear, wherein the first power-connecting member is moved along a first axis and connects the first transmission gear to the second transmission gear to transmit power to the second transmission gear; a third transmission gear; a fourth transmission gear; a second power-connecting member coaxially disposed between the third transmission gear and the fourth transmission gear, wherein the second power-connecting member is moved along a second axis and connects the third transmission gear to the fourth transmission gear to transmit power to the fourth transmission gear; and a driving mechanism for synchronously driving the first power-connecting member and the second power-connecting member to respectively move along the first axis and the second axis to selectively connect the first transmission gear to the second transmission gear, or connect the third transmission gear to the fourth transmission gear.
