安全を図るようになつている。 A rotary saw blade 17 is fixed to a disc portion 13a at the front end of the rotary shaft 13 protruding forward of the bearing cylinder 11 by a screw 16. A guide member 18, which also serves as a saw blade cover, is fitted into the bearing cylinder 11 close to the rear of the rotary saw blade 17, and is fixed with screws 19. As shown in FIG. 2, this guide member 18 is formed into a forked shape at its upper part, and has a pair of guide sides 1 extending substantially parallel to the rotary saw blade 17.
Rotating saw blade 17 cuts branch B of tree T using 8a and 18b.
It is designed so that it can be guided and moved relatively towards. Further, a cylindrical cover portion 18c is formed on the outer peripheral edge of the guide member 18 to protrude forward, and is designed to cover the outer peripheral blade portion of approximately the lower half circumference of the rotary saw blade 17 for safety.

０との接触により除去するようになつている。 A closing member 20 made of a synthetic resin with a small coefficient of friction, such as fluororesin, is attached to the front surface of one of the guide pieces 18a facing in the rotational direction of the rotary saw blade 17 with a screw 21, and the guide member 18 and the rotary saw blade 17 are connected to each other by a screw 21. A part of the gap 22 between the
This blocking member 2 prevents the braking force from entering into the rotary saw blade 17 and prevents the sap that adheres to the back surface of the rotary saw blade 17 during pruning work.
It is designed to be removed by contact with 0.

るようになつている。 Further, an arcuate recess 23 is formed on the inner surface of one of the guide pieces 18a, so that even when the rotary saw blade 17 is suddenly pressed against a branch B of the tree T, the branch B will not touch the rotary saw blade 17. As it rotates, it is once relatively moved and received within this recess 23, and after the impact has been alleviated, it is guided toward the center of rotation of the rotary saw blade 17.
前記のように構成された電動枝打ち機について
次に作用を説明する。 Next, the operation of the electric pruning machine configured as described above will be explained.

断することができる。 Now, when using this pruning machine, first suspend the same pruning machine from the shoulder or waist using the hanging cord 8, and then climb the tree T to be pruned or a ladder, etc. attached to it to reach a predetermined height. . Thereafter, when the user grasps the handle 4 and closes the switch 6 by operating the push button 6a, the electric motor 3 is driven by the battery 5. As a result, the rotating shaft 13 is rotated via the gears 14 and 15, and the rotary saw blade 17 is rotated counterclockwise in FIG. 2. In this state, when a branch B of the tree T is positioned between the guide pieces 18a and 18b of the guide member 18 and the rotary saw blade 17 is pressed against the branch B, the rotation of the rotary saw blade 17 causes the branch B to move to one of the guide pieces. 18a
After being relatively moved to the side, it is guided toward the rotary saw blade 17, and the branch B can be easily cut with one hand.
そして、この実施例では前記のように一方の案

ことができる。 In this embodiment, since the arc-shaped recess 23 is formed on the inner surface of one of the guide pieces 18a as described above, the rotary saw blade 17 is suddenly pressed against the branch B of the tree T during pruning work. Even if it is attached, the branch B is once relatively moved and received in this recess 23 as the rotary saw blade 17 rotates, as shown by the chain line in FIG.
It is guided toward the center of rotation of the rotary saw blade 17 along the inner surface of a. Therefore, pruning work can be performed safely without applying strong impact to the rotary saw blade 17.

できる。 Furthermore, in this embodiment, a closing member 20 made of a synthetic resin with a small coefficient of friction, such as fluororesin, is provided on the front surface of one of the guide pieces 18a, so that it is difficult to cut back the uncut portion of the branch B of the tree T. In case,
Therefore, the generated thin pieces of wood, etc. are transferred from the front part of the one guide piece 18a to the guide member 18 and the rotary saw blade 1.
There is no risk of it entering the gap 22 between it and 7. Therefore, it is possible to reliably prevent the possibility that a braking force will be applied to the rotary saw blade 17 due to the intrusion of a piece of wood or the like into the gap 22, and the rotary saw blade 17 can be rotated smoothly, making pruning work easy and without fatigue. It can be carried out. Furthermore, since the closing member 20 comes into sliding contact with the back surface of the rotary saw blade 17, the sap that adheres to the back surface of the rotary saw blade 17 during pruning work is removed by the closing member 20. Therefore, it is also possible to prevent the sharpness of the rotary saw blade 17 from deteriorating due to adhesion of tree sap.
なお、この考案は前記実施例の構成に限定され
