Description

Grass trimmer Technical Field The utility model belongs to the technical field of grass mowing equipment, and particularly relates to a grass mowing machine. Background Many existing garden tools have shield structures. However, in drop test or in actual use by users, the machine often falls from a high place to cause deformation, breakage and the like of the shield. To solve these problems, the prior art generally deals with the shield itself, such as changing the shield material to a more flexible PP, imparting strength to the shield itself by way of spatial contouring, making the shield stronger by way of a stiffener or the like. But these solutions obviously belong to a lightweight solution and do not really solve the drop problem. For example, the brush cutter blade has high rotating speed and large kinetic energy, the reliability of the iron shield is better than that of plastic from the aspects of protection and user psychology, but the iron shield is easy to deform after falling, so that the shield is invalid, and the current market is the plastic shield. Disclosure of utility model In view of the above, the utility model provides a grass trimmer, which can effectively solve the problem of damage of a protective cover after the grass trimmer falls down. A grass trimmer comprising a body and a shroud connected to the body, the shroud being rotatably connected to the body between a first position and a second position, the grass trimmer comprising a connector connected between the body and the shroud, the connector comprising a first portion mounted or connected to the body and a second portion mounted or connected to the shroud, the first portion cooperating with the second portion to retain the shroud bias in the first position. In an embodiment of the utility model, the body comprises a first connection stage extending from an outer side wall thereof, the shield comprises a second connection stage connected to the first connection stage, and the connection member comprises a rotation shaft rotatably connected between the first connection stage and the second connection stage.
