Abstract

The invention relates to a trimmer, in particular to a lawn trimmer preventing cutter breaking. The technical problem is to provide lawn trimmer which can prevent the cutter from breaking and causingdamage to people, and can cut off residual grass and prevent the residual grass from being stuck to influence the working efficiency. According to the technical scheme: the lawn trimmer comprises a handle, a box cover, a hollow cylinder, an annular sliding block, a vertical sliding block, a first spring and the like; the outer top of the hollow cylinder is circumferentially provided with an annular chute for guiding, two annular sliding blocks matched with the annular chute are arranged in the annular chute, and the box cover is arranged between the tops of the annular sliding blocks at the left side and the right side. According to the invention, through the matching of six-diamond holes and six-diamond rods, when the cutter touches a stone, the annular blocks can move downwards to separate the six-diamond holes from the six-diamond rods, so that the cutter stops rotating forwards, and the cutter can be prevented from rotating continuously when touching the stone, which can cause damage to people.
