Abstract

An object of the present invention is to provide a pruning machine with good operability in which an auxiliary handle can be easily adjusted in accordance with a working posture and a physique of a worker.
A trimming machine having a main handle formed on a housing and a loop-shaped auxiliary handle detachably attached to the housing, wherein the auxiliary handle is turned in a circumferential direction around an attachment portion to the housing as an axis. It is characterized by being movable. Further, the auxiliary handle can be fixed at an arbitrary position within a rotation range.

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a trimming machine for trimming hedges, plants, and the like.
[0002]
[Prior art]
FIG. 3 and FIGS. 8 to 10 show the structure of a conventional pruning machine.
[0003]
As shown in FIGS. 3 and 9, the auxiliary handle 3 of the pruning machine has a structure in which a columnar member is formed in a substantially C shape, and a convex portion 7 is disposed at both open ends 6 having a substantially C shape. ing. When the auxiliary handle 3 is mounted on the housing 1, the protrusion 7 of the auxiliary handle 3 is fitted into the auxiliary handle mounting hole 5 formed at an angle α in the housing 1 as shown in FIG. As described above, the auxiliary handle 3 and the housing 1 are fastened by tightening the bolts 9 from both sides to the nut 10 held inside the housing 1.
[0004]
At the time of the cutting operation, as shown in FIG. 11, the main handle 2 and the auxiliary handle 3 integrally formed on the housing 1 are respectively gripped, and the cutting blade 4 mounted on the front portion of the housing 1 cuts a hedge or a plant. .
[0005]
[Problems to be solved by the invention]
Since the auxiliary handle mounted on the housing is fixed at the position of the inclination α, the operability may be felt bad if the working posture or the personal physique changes.
[0006]
An object of the present invention is to provide a trimming machine with good operability, which can easily adjust an auxiliary handle to a position easy to hold in accordance with a working posture.
[0007]
[Means for Solving the Problems]
The above object is achieved by enabling the auxiliary handle to be rotatable about a mounting shaft and capable of being fixed at an arbitrary position.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of a pruner according to the present invention is shown in FIGS.
[0009]
First, as shown in FIG. 4, the auxiliary handle mounting hole 20 of the housing 1 is configured such that the convex portion 7 formed at the open end of the auxiliary handle can rotate around the mounting bolt shaft 8 within the range of the angle β. It is formed.
[0010]
Next, as shown in FIGS. 5 and 6, an opening 27 is provided in the housing 1, and a ring 21 rotatable on a mounting bolt shaft is provided so as to be operated from the housing opening 27. . The ring 21 is formed with a left-hand screw 22 on one end surface on the rotating shaft and a right-hand screw 23 on the opposite end surface. The auxiliary handle 3 is detachably fixed to the housing 1 with left-handed and right-handed hexagonal bolts 24 and 25 corresponding to the screws 22 and 23 formed in the ring 21.
[0011]
As shown in FIG. 2, the bolt insertion side seating surface 26 at the open end of the auxiliary handle 3 is formed in a hexagonal shape that matches the head shape of the mounting hexagonal bolts 24 and 25.
[0012]
The operation of each part by the operation of the ring 21 will be described with reference to FIGS. When the ring 21 is rotated in the direction a in FIG. 5, the hexagonal bolts 24 and 25 are fitted into hexagonal holes formed in the bolt insertion side seating surface 26 of the auxiliary handle 3 to rotate as shown in FIG. Therefore, the left screw bolt 24 moves in the direction of arrow c and the right screw bolt 25 moves in the direction of arrow d, and the open end 6 of the auxiliary handle and the housing 1 are fixed in close contact. Conversely, when the ring 21 is turned in the direction b in FIG. 5, the left-handed bolt 24 moves in the direction of arrow e and the right-handed bolt 25 moves in the direction of arrow f as shown in FIG. The contact force between the open end 6 of the housing 3 and the housing 1 is weakened, and the auxiliary handle 3 can rotate within the range of the angle β.
[0013]
Thus, the structure is such that the rotation and fixing of the auxiliary handle 3 attached to the housing 1 can be easily performed only by operating the ring 21.
[0014]
Even if the ring 21 is loosened during operation, the mounting hole 20 formed in the housing 1 and the projection 7 of the auxiliary handle interfere with each other and do not move beyond the rotation range β. It is also a structure that can prevent it from hitting the housing 11 or the housing 1.
[0015]
