Description

[Detailed description of the invention] (a) Industrial application field The present invention is a brush cutter grip in which a bearing body that rotatably supports a rotary blade and an engine are connected by a tubular connecting rod. It is related to the device.

(b) Prior Art Conventionally, in this type of brush cutter, the operator used an elastic material provided at the end of the handle that is fixed in the middle of the connecting rod to attach the grip to the outer periphery of the connecting rod at the intermediate position between the handle and the engine. While holding the mating grips made of elastic material with both hands, the rotary blade rotated by the engine was used to cut grass, etc. on the ground.

(c) Problems to be solved by the invention As shown in FIG. Since the inner diameter of the grip 5 was fitted to the diameter, the outer diameter of the grip 5 was larger than the outer diameter of the connecting rod 3. The outer diameter of the connecting rod 3 is set depending on the size and performance of the brush cutter, and the grip 5 that fits into the conventional connecting rod 3 has an outer diameter that is too large for the operator to use. The problem was that it was difficult to hold and work was difficult.

(d) Means for solving the problem In the present invention, the inner diameter portion of the grip made of an elastic material is engaged with the recessed portion formed integrally by press-molding the outer periphery of the connecting rod at an appropriate position.

(e) Function The present invention reduces the outer diameter of the grip by engaging the grip with a recess provided on the outer periphery of the connecting rod.

(f) Embodiment In FIGS. 1 and 2, 7 is a bearing body that rotatably supports the rotary blade 9, and 11 is a tubular connecting rod that connects the bearing body 7 and the engine 13. A shaft 15 passes through it. 17 is a rubber grip that fits into the handle 19 fixed at an intermediate position of the connecting rod 11; 21 is a recess 23 integrally formed by press-molding the outer periphery of the connecting rod 11 at an intermediate position between the handle 19 and the engine 13; It is a rubber grip that fits into the inner diameter of the grip.

In the above embodiments, the operator
7, 21 are held with both hands, and the rotary blades 9, 9 rotated by the drive of an engine 13 to cut grass, etc. on the ground. When working, the grip 21 has a small outer diameter, so it is easy to hold and work is easy.

(f) Effects of the invention Since the invention has the configuration as described in the claims, the outer diameter of the grip does not become large, making it easy to grip, and therefore mowing work can be easily performed. Moreover, it is easy to process and can be manufactured at low cost, and does not reduce the strength and rigidity of the connecting rod.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well. Further, the symbols shown in the claims do not limit the technical scope of the present invention.
