摘要：

The present invention relates to a grass cutter including a main body and a plurality of blades provided in the body to protrude. The main body is provided with a blade interference means which holds one side of a blade so as to allow the blade not to protrude in the case of being lower than a preset centrifugal force. The blade interference means includes a ball insertion hole which is formed in an upper cover coupled to the upper portion of the main body and is provided with a ball locking jaw at the lower end, a ball which is provided in the ball insertion hole and pushes the upper face of the blade in a state of putting on the ball locking jaw, a stopper which is bolt-jointed at the upper cover such that the ball is not separated from the ball insertion hole, and a spring which is supported by the stopper and pressurizes the ball to have elasticity downwards. According to the present invention, before the grass cutting blade is rotated at a high speed, one side of the grass cutting blade is pressed or held with significant pressure by the interference means so as to allow the blade not to easily protrude from the main body, thereby reducing the frequency of accidents from a grass cutter.
