As shown in FIG. 1, the plurality of steel wires 10 are fixed to the coupling units 30, which are a plurality of coupling holes formed on the side surfaces of the holder unit 20, respectively. In addition, the central portion of the holder portion 20 protrudes downward from the position where the plurality of steel wires 10 are fixedly installed, so that the center portion of the holder portion 20 is earlier than the steel wire 10 at the time of weeding operation. By being in contact, the steel wire 10 can be prevented from hitting the floor to bend.

On the other hand, as shown in Figure 12, the holder portion 20 may be manufactured in a plate shape, in this case, a plurality of coupling ring 380 is fixed to the outer side of the center of the upper surface of the holder portion 20, a plurality of It will be desirable to allow the steel wire 10 to be detachably coupled to each of the plurality of coupling rings 380.

As shown in FIG. 12, the coupling ring 380 and the steel wire 10 are coupled to and installed on one side of the upper surface of the holder 20, so that some plates of the flat holder support the steel wire 10 in a horizontal direction. This prevents the steel wire 10 from being bent by hitting the bottom by sagging toward the bottom, rather than maintaining the horizontal line 10 during the weeding operation.

On the other hand, the steel wire 10 coupled to the holder 20 as shown in Figure 19 (a) is arranged in parallel to the ground, the end of the line wire 101 of the steel wire 10 is the holder 20 It may also be desirable to fabricate such that the curve is formed in advance in the rotation direction.

As such, the steel wire 10 having the curved ends in the horizontal direction has a shape that is pre-bent in the direction in which the force is applied to the steel wire 10 in the weeding process, and thus the steel wire 10 is not bent in the weeding process. Will be prevented.

In addition, as shown in (b) of FIG. 19, the steel wire 10 coupled to the holder portion 20 is arranged in parallel to the ground, the end portion of the steel wire 10 is formed upwardly curved in the opposite direction of the ground It would be desirable to fabricate as much as possible. This prevents the steel wire 10 from being bent by hitting the floor by sagging toward the bottom without maintaining the horizontal line during the weeding operation.

In addition, as shown in FIG. 19, the steel wire 10 may be manufactured to have a circular cross section, or may be manufactured to have a rectangular or rhombus shape, and thus the cross-sectional shape may be manufactured to have a long or rhombus shape. The steel wire 10 has the advantage of being able to prevent deformation of the steel wire 10 during the weeding operation by increasing the bending stiffness, and improve the cutting force.

The steel wire 10 implemented as described above has elasticity embedded therein and has excellent restoring force or elastic force due to its elasticity, and is used to cut and strike an object by being fluidly fastened with the above-described holders 20 to. Can be used for weeding,

In use, even if the obstacles hidden in the grass and the liner are strongly collided, the repulsive force is hardly generated by rotating or evacuating up, down, left, right or left, right, upside, and on the other hand, scattering debris is inversely proportional to the repulsive force. Because it occurs in a hostile manner and bends in an ellipse only in one direction of rotation, it can reduce the economic cost of the user by providing a long service life until most of the wire is worn out.

In addition, since there is no vibration caused by rotational friction by supplying a uniform product, it is possible to provide an ideal lawn mower cutter structure in which fatigue is improved and work efficiency is improved.

The cutter structure for mowers of the present invention can be used for cutting and hitting a cutter blade of a lawnmower for mowing, such as a farm head or a garden or a roadside, or an object.
