The safety switch mechanism comprises an inner pipe and a pipe sleeve piece which form into the sliding connection by means of sleeve joint, a safety switch arranged in the pipe sleeve piece and provided with a contact elastic sheet, a triggering piece for triggering the safety switch by being contacted with the contact elastic sheet when sliding in the inner pipe, and an elastic piece for driving the triggering piece not to be contacted with the contact elastic sheet; the safety switch, the triggering piece and the elastic piece are arranged at the same side of the inner pipe; and the grass cutter provided by the invention further comprises a main machine body and a hollow first-grade handle rod which is in rotatable connection with the main machine body on the basis of the safety switch mechanism, wherein the main machine body is provided with a motor and a control circuit controlling the motor, the pipe sleeve piece is arranged at the end head of the first-grade handle rod, the safety switch mechanism can guarantee the safety of operators, and when users are near to the main machine body by accident, the motor can be automatically turned off, so that the possibility of accidents can be reduced.

Description

technical field [0001] The invention relates to a lawn mower and a safety protection device thereof, in particular to a lawn mower with operation protection and a safety switch mechanism thereof. Background technique [0002] The lawn mower is a tool used to level the lawn. It mainly drives the blade through the motor of the main body to cut the overlong grass blades. In order to achieve high-efficiency mowing, the motor power of the lawn mower is relatively large. Therefore, it also has certain hidden dangers to the personal safety of the operator. Now, the operator is generally kept as far away from the main body as possible through a longer handle bar to avoid danger. In this case, it is possible that the handle lever may be accidentally retracted during operation, causing the user's hands to be close to the main body, causing danger. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provid...
