An actuating mechanism includes a gear shifting motor, a first transmission gear, second transmission gears, gear shifting screws, a push block, a shift fork, a shift block and a linear driving device. An output shaft of the gear shifting motor is provided thereon with the first transmission gear engaged with the second transmission gears; the second transmissions gears are fixedly connected to the gear shifting screws; the gear shifting screws are in screw thread connection with the push block provided thereon with a through hole; one end of the shift block is connected to the linear driving device, and the other end is aligned with a groove on the shift fork after inserting into the through hole. The linear driving device corresponding to a shift position drives the shift block; the gear shifting motor drives the first transmission gear; and the second transmission gears drive the gear shifting screws.
