Abstract
The disclosure relates to a traction device and a traction method. The traction device includes: a support chassis; a swing arm, one end of the swing arm is rotatably connected to the support chassis by a rotating shaft such that the swing arm can be switched in a retracted state and a deployed state, wherein the swing arm in the deployed state is adapted to drive the wheel of the vehicle to rotate and tow the vehicle; a driving mechanism, connected to the swing arm, wherein the driving mechanism is capable of driving the swing arm to horizontally rotate around the rotating shaft to switch the swing arm between the retracted state and the deployed state; and a rolling assembly, disposed on a side of the support chassis and being capable of preventing the wheel from contacting with the side of the support chassis when the vehicle is towed.
