Description

Blade for cutting off grass cutting rope

Technical Field

The utility model relates to a cutting blade field, concretely relates to a blade for cutting off cut grass rope.

Background

The mower is a garden tool, and adopts the rotation of a mowing rope to mow, after the mower is used for a period of time, the surface of the mowing rope is rough, the mowing effect is poor, a blade is required to cut off a working part to cut the mowing rope, and a new mowing rope is pulled out again to work, but the cutting surface of the existing blade is a straight line, as shown in figure 1, the contact surface of the existing blade with the mowing rope is small, and the cutting effect is poor, so that the blade for cutting off the mowing rope with good cutting effect is very important.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a blade for cutting off straw rope, including the blade body, at least one side of blade body is provided with the cut surface, and the cut surface is the arc, and this curved arc portion is to this internal bending of blade. The cutting surface is a wedge formed by an upper inclined surface arranged on the upper surface of the blade body and a lower inclined surface arranged on the lower surface of the blade body.

The cutting surfaces are arranged on two sides of the blade body. The blade body is provided with a mounting part, wherein the mounting part is arranged at one end of the blade body, and a mounting hole is formed in the mounting part. A groove is arranged between the mounting part and the cutting surface at one side of the mounting part. The mounting portion and the blade body are integrally formed.

Compared with the prior art, the utility model has the advantages of: the utility model discloses simple structure, through the utility model discloses the rope that cuts grass of cutting lawn mower, because the utility model discloses the arc design of cutting surface, cutting edge and the rope area of contact that cuts grass are big when cutting off, cut off effectually.
