Further, described locating piece is provided with the location-plate along safety handle setting radial relative to clutch lever hinge; On described safety handle, under corresponding itself and the cross-shaped state of clutch lever, the side of safety handle corner area is provided with the draw-in groove matched with location-plate dorsad; Rotating safety handle makes the draw-in groove on it and location-plate clamp and effectively can locate clutch lever, simple to operate.
Further, also comprise to be connected between safety handle and clutch lever and for safety handle provide elastic force to make safety handle free state under and the elastic component of cross-shaped state between clutch lever; Safety handle is limited the rotational angle of clutch lever all the time under the elastic force effect of elastic component, there is good anti-misoperation function, and can automatically and location-plate clamp, simplified operation, easy to use.
Further, described elastic component is torsion spring; Described torsion spring set is loaded on the hinge between safety handle and clutch lever; Be convenient to the installation of elastic component and compact overall structure.
Further, described handlebar stem is fixed with for supporting mutually with safety handle and fixedly mounting the gripper shoe of locating piece; Safety handle is installed on inside clutch lever by bolt and nut, safety handle is made to be that hinge rotates with bolt, locating piece and the corresponding safety handle of gripper shoe are fixed on inside handlebar stem, existing clutch handle structure basis carries out improving, is beneficial to and applies.
Further, described handlebar stem is fixed with for rotating backward spacing baffle plate to clutch lever; Namely limit clutch lever by baffle plate and rotate backward extreme position, clutch lever is made to be undertaken spacing when rotating backward by baffle plate, clutch lever can be adjacent to baffle plate and the handlebar stem also interior rotation of angular range betwixt, the direction closed up with handlebar stem gradually with clutch lever is forward, otherwise is reverse.
The invention has the beneficial effects as follows: grass dressing machine clutch system of the present invention, can prevent from bringing injury to complete machine or the person during operator's maloperation, can locate preferably under clutch lever free state simultaneously, can prevent grass dressing machine from vibrating causes clutch lever ceaselessly to swing, avoid the syndeton between clutch lever and handlebar stem to damage, abate the noise.
