Abstract

The present invention relates to a scissors that can cut the leaves of soft plants, such as grass or weeds of mausoleum, and increase the cutting speed when cutting weak stems such as boxwood.

The present invention is characterized by being able to cut both when the blade is closed and opened with a handle that is capable of cutting the object in both directions by adding blades having both blades to the front and rear of the existing scissors, respectively.

Description

Double Edged Grass Shears {a two_edged hand mower}

Conventional lawn shears have a slower speed because the blade is only cut in one direction, i.e., only when closing the handle.

In addition, there is a problem that you need to trim several times in order to even the cut surface because the height of the cut grass is not even because the cut area is small.

The present invention is designed to solve the above problems, by adding a blade that can be cut to move the handle once to cut a lot of grass to increase the cutting speed, to broaden the cutting area at a time to even the cutting surface.

When the blade is closed, it can be cut at twice the speed of the conventional scissors, and when the blade is opened, it can be cut at the same speed as the conventional scissors. If you have a large area for cutting at once, you can get the effect of leveling the surface if you are skilled at cutting.

Since the blade angle of the upper plate was lowered by about 10 [degrees] than the lower plate, the upper plate blade was configured to wear more than the lower plate. Thus, if the top plate is worn a lot due to the amount of work can be used to replace the spare parts (c, d) spare parts immediately on the job site.

The present invention is to increase the cutting speed of the existing blades (in this design, corresponding to the short blades (①, ③)), as shown in Fig. 1 and [Fig. 2] both blades (②, ④) By adding one more each) was cut to open the blade, it was configured to cut even when closing the blade.

In addition, in order to make the maximum opening angle constant, the opening stop protrusion (⑨) of [FIG. 1] or [FIG. 2] was configured, and the closing stop protrusions (⑩) of [FIG. 1] or [FIG. It was configured to stop and hit.

When closing the handle in the cutting progress of Fig. 3, the closing blade (⑧) of the upper and lower blades (①) and the lower blade both (8), and the closing blade (⑤) of the upper blades as shown in the closing progress (㉮) Cut the grass marked with '∨' between the lower blades (③). When opening the handle, cut the grass marked with '∨' between the hot blade (⑥) of the upper blade and the hot blade (⑦) of the lower blade, as shown in the heat progression (㉯).

The lower blade was formed at an angle of about 20 [deg.], And the upper plate was formed at 30 [deg.] So that the blade of the upper plate was worn more than the lower plate.

When the frequency of use is high, the blade of the top plate is worn out a lot, so the top plate can be detached from the worn blade as shown in [Fig. 4] so that the blade pieces (c, d) can be detachably attached and used at home or in the field. Produced so as to replace the top of [1] with the top of [4].

Both the blade (c) and the short blade (d) of Fig. 4 is a stopper (e) formed with a stopper (e) for preventing movement in the blade progress direction and the body (b) is attached to the handle (b) ) Is fixed by arc welding, and the two blade pieces (c) and the short blade pieces (d) are inserted between the stopper (e) and the sides of the body (b), and then screwed together.

Claims (3)

It is a form of the double-blade with the blades on both sides to the existing scissors, and about a double-winged lawn shears that can increase the cutting speed about three times, A double blade portion configured by adding double blades (②, ④) to existing scissors to cut the handle and open it, that is, to reciprocate; The stopper (e) configured to arc-weld the fastener (a) and the trunk (b) and to fix both blade pieces (c) and short blade pieces (d) at both ends of the fastener (a); Fitting between the blade pieces (c, d) so that the blade can be easily replaced by loosening the screw when the blade is worn while the blade is worn between the sides of the body (b); Double-winged grass shears characterized in that. The method of claim 1, Double blade grass scissors characterized in that the upper and lower blades (②) and lower blades (④) with both blades to open and close the scissors, that is to cut in both directions. The method of claim 1, Since both blade pieces (c) and single blade pieces (d) are configured to be joined using a fastener (a), both blade pieces (c) and single blade pieces (d) are worn out and need to be replaced. Double blade grass scissors, characterized in that can be replaced with a spare blade to loosen.
