Description

  The present invention relates to a branch cutting stick for cutting a branch of a tree at a high position using a long stick.

Until now, in order to cut off the branches of tall trees such as garden trees, high branch cutting poles with branch cutting poles attached to the ends of long poles have been provided.
However, the conventional high-pruning shears have a fixed blade orientation, and even though the branches can be cut vertically, the cutting angle cannot be adjusted. Could not be pruned.
Therefore, the present inventor has proposed a pruner that can adjust the cutting angle. (See Patent Document 1)
However, when adjusting the angle of the pruner, it was necessary to lower the heel to the ground and rotate the heel to the desired angle.
Especially in pruning work such as pine, it was necessary to change the angle frequently to adjust the shape of each branch and branch, and the angle adjustment work each time was very troublesome.

Moreover, if the high branch is about 5 cm thick, it is difficult to manually cut off the branch, and powerful saw cutting with an electric tool is required. In addition, it is indispensable to use a power tool to cut high-density, dense-leaf clippers.
In the past, such work was done by climbing a stepladder or ladder with a power tool.
But without a stepladder or ladder, I couldn't do that.
JP 2003-125648 A

  The present invention has been made to solve the conventional difficulties, and the cutting angle can be freely adjusted while continuing the cutting operation by the operation of the hand without lowering the long hook, and the cutting and branching can be performed. By attaching a power tool such as a hair clipper, it is possible to provide a tool that can perform saw cutting of a thick branch or trimming of branches and leaves while adjusting the cutting angle.

In order to solve the above-mentioned problems, the present invention is provided with a pivot portion having a pivot shaft orthogonal to the longitudinal direction of the elongated rod at the upper end portion of the elongated rod connected to a telescopic telescopic metal pipe. The rod support portion is pivotally supported on the pivot shaft of the pivot portion so as to swing up and down, and a rotary tube shaft is provided in a direction crossing the direction of the pivot shaft.
The branch cutting rod is fixed to the rotary tube shaft by a rod rotating handle supported by the rod supporting portion so as to be rotatable about the longitudinal direction of the rod.
Further, the branch cutting rod has a blade opening / closing handle that is bent in the opening / closing direction of the rod from the fulcrum part of the rod and has a wire stopper at its end, and between the blade rotating handle and the blade opening / closing handle. The blade is opened by the bias of the spring provided.
And a reel is provided in the lower part of the eaves, the lower end is wound around the reel, and the upper end passes through the elongate pipe and is connected to the wire stopper of the blade opening / closing handle of the branch eaves through the rotary tube shaft. Install the open / close operation wire.
Furthermore, in the middle part of the eaves, the wire pulled out from the eaves tube in the case attached to the eaves can be wound and unwound by rotation of a branch cutting handle provided outside the case. Wire pulling means is provided.
Then, the branches of tall trees can be cut off by operating the handle for cutting branches.

According to a second aspect of the present invention, in the configuration of the above invention, a tube shaft rotating means is provided on the rotating tube shaft of the heel support portion so as to rotate by the operation of the wire.
Then, a rotating operation wire having a lower end wound around the reel and an upper end passing through a long tube and connected to the tube shaft rotating means is installed.
Furthermore, a wire drawing means that enables the wire drawn out from the inside of the bag in the case attached to the eaves to be wound and rewound by rotation of a handle for turning the hook provided outside the case, It is provided in the middle part of the long wall.

  Further, the invention according to claim 3 is the construction of the invention described above, wherein the wire drawing means has a wire drawn from the inside of the long tube inserted into the cylinder, and the base of the handle for rotating the bag is inserted in the middle of the cylinder. Is fixed, and the cylindrical body is rotated by the rotation of the handle so that the wire can be wound and unwound.

  Furthermore, according to a fourth aspect of the present invention, in the configuration of the above invention, a winding spring is attached to the shaft of the reel, and the wire loosened when the length of the long rod is adjusted is automatically wound by the force of the winding spring. It is constructed so that it can be worn.

  According to a fifth aspect of the present invention, in the configuration of the above invention, a tool fixing base having a tool fixing means for fixing the electric tool is provided at the rear end portion of the rotary tube shaft to which the branch cutting rod is fixed. The power tool cord is inserted into a long tube and connected to a power source.

According to a sixth aspect of the present invention, in the configuration of the above invention, the cord of the electric power tool is connected to the power source via the reel.

For both cord relay points in the case, the power cord is connected to both poles with a single line branch.
In addition, a power transmission cord is connected to both cord relay points on the winding shaft by branching to a single wire at both poles.
The power cord is prevented from being twisted when the power transmission cord is wound around the reel.

Since the branch cutting rod of the present invention has the above-described configuration, when adjusting the length of the long rod by extending and retracting the telescopic metal pipe, the wire loosened when the metal pipe is shortened is automatically reeled by the force of the winding spring. When the metal pipe is lengthened, the wire is sent out from the reel so that the metal pipe can be extended for a long time without being obstructed by the wire.
Then, while keeping the wire moderately stretched with a wire presser screw, etc., keep the wire length between the reel and the blade opening / closing handle constant, and then pull the wire provided on the hand of the long blade. By winding and pulling the wire with the biasing means, the blade of the scissors opened by the bias of the spring can be closed. That is, when the wire is pulled by the wire pulling means, the branches sandwiched between the blades are cut off.
Further, in the case of adjusting the angle of the heel in the conventional branch cutting hoe, the long heel must be lowered on the ground and manually rotated to the angle desired to change each time. By rotating the handle of the wire pulling means without lowering the ground on the ground, the wire is wound up, and the rotating tube shaft connected to the wire is rotated to freely adjust the angle of the branch culling The branch can be cut.

  In addition, various power tools can be attached to and detached from the tool fixing base provided at the upper end of the long wall, and by attaching power tools such as sawing and branch clippers to the tool fixing base, it has not been possible to This makes it easy to cut off thick branches at high places and to cut and form leaves at high places into a desired shape, and turn the rotary tube shaft with a wire pulling means to lower long ridges to the ground.
