Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a hand-push lawn mower, which solves the problem that the protection measures of the existing hand-push lawn mower are not ideal, and there are many sundries on the lawn, often mixed with gravel and branches. When cutting grass, the rotating blade will be damaged or even broken, and there is a big safety hazard. Moreover, when cutting wet plants, the cut debris or grass blades will accumulate and stick for a long time Together, the blades of the cutter head are blunted, resulting in a large number of plants not being cut, making the mowing incomplete, affecting the cutting efficiency, and reducing the problem of performance

Abstract

The invention discloses a hand-push lawn mower, which comprises a body, the shrinkable air bag is arranged on the top of the inner wall of the body and is located between the top of the surface of the sliding push plate and the two sides corresponding to the inner wall of the body, and the air flow channel is opened on the top of the inner wall of the body Inside the body and close to the top position, one end of the air flow channel communicates with the end of the contraction air bag, the carding device is fixed on the bottom of the sliding push plate through a connecting rod, and the cutting device is arranged inside the body and away from the carding device One side of the air flow passage away from the deflation air bag is mated and connected with the top end of the cutting device through a rotary connector. The present invention relates to the technical field of electric tools. This walk-behind lawn mower achieves the purpose of preventing hard objects and anti-sticking. It can clean up hard objects in time to avoid rigid collision of the cutter head. It is safe and reliable, and at the same time reduces wet debris or grass blades sticking to the blade. , to ensure the sharpness of the tool, making the cutting fast and thorough, improving work efficiency and performance.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a hand-push lawn mower.
