A mower comprises an engine, a knife head, a belt and a clutch. The clutch comprises a motor, a gear box, a traction mechanism and a clutch pulley, the traction mechanism comprises a screw, a buckling member connected on the screw in a threaded manner, and a connecting member acting with the buckling member, the first end of the screw is away from a gear box while the second end of the screw is connected with the gear box, the motor starts to drive the screw to rotate after being decelerated through the gear box, the screw rotates to drive the buckling member to move along the axial direction of the screw to drive the connecting block and pull the clutch pulley to move from a first position to a second position to tension the belt, the engine drives the knife head to rotate, the buckling member loosens the connecting block, the connecting block moves and resets along a first direction, and the clutch pulley resets from the second position to the first position, and when the belt is loose, the engine cannot drive the knife head. The mower is simple and labor-saving to operate and more attractive.
Description
technical field [0001] The present invention relates to a lawnmower, and more particularly to a clutch for transmitting power between an engine and a cutter head of the lawnmower. Background technique [0002] Lawn mowers are widely used to trim and trim lawns to keep them level. Existing lawn mowers generally include an engine, a cutter head, and a clutch. The engine is used as a power source to drive the cutter head through a belt transmission. The clutch makes the belt tension or loose, and the engine drives the cutter head when the belt is tensioned Turn to mow, disconnect the drive from the engine to the cutter head when the belt is slack. The existing clutch is usually operated and controlled by the user through a handle bar, which is relatively laborious in operation, and in addition, it is not beautiful enough in appearance. Contents of the invention [0003] The invention provides a simple and labor-saving lawnmower and its clutch. [0004] A clutch, comprising...
