Abstract
The utility model discloses a clutch structure and a grass raking machine applying the same. The clutch structure comprises a rotating shaft, a bracket bottom plate, a limit top plate and an output wheel. The rotating shaft is provided with a plurality of grooves which are arranged radially. Springs are arranged in the grooves. Ports of the grooves are provided with movable pins which are elastically pressed against the inner ring wall of the output wheel by the springs. The inner ring wall of the output wheel is provided with arc grooves. When the positions of the grooves correspond to the arc grooves, the front ends of the movable pins are clamped in the arc grooves under the action of the springs. The clutch structure is arranged in the grass raking machine. When the grass raking machine works normally, components in a clutch move synchronously. When a load excesses the bearing capacity of the clutch, the movable pins in the clutch are separated from the arc grooves of the output wheel at convenience under the torsion action, so that a belt drives the output wheel to carry out rapid idling and the rotating shaft is in the relative static state to play a role on protecting a motor assembly and a transmission structure.
