An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a hollow operation stick, to which an engine 2 is attached to the base end via a clutch case 2a, and a cutting blade 4 is attached to the tip via a gear box 3. It is being A transmission shaft 5 shown in FIGS. 2 to 6 is inserted and supported in the operating rod 1 between the clutch case 2a and the gearbox 3, so that rotational power from the engine 2 is transmitted to the cutting blade 4. ing. A grip 6 is attached to the part of the operating stick 1 closer to the clutch case 2a, and a loop-shaped handle stick 7 is attached to the side closer to the tip of the grip 6. A tutle lever 8 is attached. Further, a cutting blade cover 9 is attached to a portion of the operation stick 1 near the gear box 3. As shown in detail in FIGS. 3, 4, and 6, the operating rod 1 is formed of a hollow pipe having four grooves 10 arranged at equal intervals in the circumferential direction along its length. , Therefore, compared to the conventional operating rod formed of a circular pipe, even if the outer diameter is made thinner, the
It provides rigidity and strength. The clutch case 2a is shown in FIGS. 2 and 3.
As shown in detail in the figure, it has a mounting boss part 11 that is inserted into and fixed to the base end of the operation rod 1, and this mounting boss part 11 has a bearing support part l' 1 and a fitting part. l1 , the bearing support part l' 1 has a circular cross section, and the fitting part l1 has a protrusion 11a that fits into the groove 10 of the operating rod 1. . A bearing 12 is fitted into the bearing support portion l' 1 to support the connecting portion in a state where the transmission shaft 5 and the boss portion of the clutch drum are connected. Further, a slit 13 is provided in the fitting portion l1 , and is adapted to be tightened and fixed with a tightening bolt 13a. In addition, as shown in FIG.
A slit is formed in the boss portion 14, and a protrusion 14a is formed on the inner circumference of the boss portion 14, so that the concave portion 1 of the operating rod 1 is formed.
0 and tighten with the tightening bolt 14b,
It is supposed to be fixed. Furthermore, as shown in FIGS. 5 and 6, the gearbox 3 is also provided with a mounting boss 15 similar to the mounting boss 11 of the clutch case 2a. Further, the mounting boss portion 15 is provided with a bearing support portion l' 2 and a fitting portion l2 , and the drive shaft 5 and the bevel gear 16 are connected to each other by the bearing support portion l' 2 and rotated by the bush 17. This connecting part is supported freely, and the fitting part l2 has a concave groove 1 of the operation stick 1.
A protrusion 15a that fits with the 0 is provided. Furthermore, a slit 18 is provided in the fitting portion l2 , and the fitting portion l2 is tightened and fixed with a tightening bolt 18a. In the brush cutter configured in this way, the clutch case 2a has the protrusion 11a, the handlebar 7 has the protrusion 14a, the gearbox 9 has the protrusion 15a,
Insert each into the groove 10 of the operating rod 1 and tighten with the tightening bolts 13a, 14b, 18a to remove the operating rod 1.
Since the engine 2, handlebar 7, and cutting blade 4 do not rotate in the circumferential direction with respect to the operating lever 1, it is safe. In addition, since the operation stick 1 is provided with a groove 10 in the length direction, it can withstand sufficient strength even if it is made thinner than the conventional one.This makes the operation stick 1 lighter, and the overall size is smaller. A lightweight brush cutter can be constructed. In the above embodiment, the concave groove was formed over the entire length of the operation stick 1, but at least the clutch case 2a and gear box 3 mounting boss portion 11,
15 may be formed on both ends to be fitted.

As is clear from the above description, the present invention has the following effects. (A) Multiple grooves are formed along the entire longitudinal length of the operating rod, and the protrusions are fitted into these grooves, and the engine clutch case, handle rod, and cutting blade gearbox are tightened and fitted. Therefore, the control stick is thinner than the conventional one, has sufficient strength, can be made lighter and smaller, and these fitting parts do not easily come loose due to vibrations of the aircraft, etc. Since the attached body such as the gearbox does not rotate in the circumferential direction with respect to the operating stick, the work can be carried out safely. (B) The handle stick can be adjusted in position along the longitudinal direction of the operating stick, and is prevented from rotating relative to the operating stick as described above, so the locking mechanism for the operating stick is particularly strong, improving operability. is good.
