Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with an operating lever on the hand side of a pole and an opening / closing tool on the tip side so that the opening / closing tool can be opened and closed by operating the operating lever.
The present invention relates to a remote control tool.

[0002]

2. Description of the Related Art The above-mentioned speed-changing operation tool is widely used for pruning a high-branch of a tree by using, for example, an opening / closing tool as scissors. However, in order to reach the opening / closing tool at a high place that cannot be reached, it is necessary to lengthen the pole of the remote control tool (for example, 2 m or more). for that reason,
A device for extending the pole in several steps was made (Japanese Patent Laid-Open No. 1-1.
No. 99777 public information).

[0003]

In the present invention,
An object of the present invention is to make the length of the pole of the remote control tool infinitely variable, to improve its operability, and to provide the number of parts at a low cost. (The above-mentioned JP-A-1-
Japanese Patent Publication No. 1997777 also discloses a technique for continuously changing the length of the pole, but the operation is troublesome. )

[0004]

A remote control tool of the present invention will be described with reference to the drawings. The pole 1 is the outer pipe 1a
And a middle pipe 1b which slides inside thereof, an operating lever 2 is provided on the hand side 1c of the pole 1, and an opening / closing tool 3 is provided on the tip side 1d. Further, a connection means 4 is provided inside the pole 1 so as to penetrate the pole 1, and this connects the operation lever 2 and the opening / closing tool 3.
A lock means 5 is provided between the outer pipe 1a and the middle pipe 1b to restrain the sliding between the two pipes.
Further, the connecting means 4 is formed by the hand side connecting means 4a and the tip side connecting means 4b, the hand side 4c of the hand side connecting means 4a is attached to the operating lever 2, and the tip side 4d of the tip side connecting means 4b is opened and closed. It is attached to the tool 3. Further, an engaging means 6 is provided so that the tip side 4e thereof is engaged with the tip side coupling means 4b by pulling or pushing the proximal side coupling means 4a.

Further, according to a preferred embodiment of the present invention, the tip side 4e of the hand side connecting means 4a is formed with an uneven portion 4f having an unevenness in the axial direction, and the tip side connecting means 4b is engageable with the uneven portion 4f. It is a concavo-convex bar on which irregularities 4g are formed.

[0006]

With the locking means 5 of this remote control tool released, the front and rear of the pole 1 are held and expanded and contracted, and the locking means 5 is operated at an appropriate length to fix the length. Then, when the operation lever 2 is operated, the hand side connecting means 4a is pulled or pushed to become integrated with the tip side connecting means 4b, and the opening / closing tool 3 connected thereto is opened and closed.

[0007]

EXAMPLES Examples will be described below with reference to the drawings. The outer pipe 1a of the pole 1 is formed on the hand side, and the middle pipe 1b is formed on the tip side. The operating lever 2 is pivotally supported by the shaft 2a on the proximal side 1c of the outer pipe 1a,
It is attached to the hand side 4c by a shaft 2b. The operating lever 2 is biased toward the tip side by a spring 2c. Further, a fixed lever 2d is provided on the hand side 1c. The opening / closing tool 3 is pivotally supported on the tip side 1d by a shaft 3a, and is attached to the tip side 4d by a shaft 3b. Further, the tip side 1c is extended to form a fixed blade 3c.

A small pipe 7 is fixedly provided on the inner side and the near side of the outer pipe 1a. A slope plate 6a is provided on the inner side and the lower side of the tip side of the small pipe 7, and the tip side 4e is pushed upward by pulling the hand side connecting means 4a toward the hand side, and the uneven portion 4f becomes uneven. By engaging with 4g, the tip side 4e and the tip side connecting means 4b are engaged with each other to form the engaging means 6.

Concavities and convexities 1e are formed in the axial direction on the upper surface of the middle pipe 1b. On the other hand, the locking means 5 is provided on the distal end side of the outer pipe 1a, and an engaging piece 5a having concave and convex portions for engaging with the concave and convex portions 1e is fitted therein, and a lever 5b for moving the engaging piece 5a up and down is provided. It is locked up. The engagement piece 5a and the cam surface 5c of the lever 5b are bonded by a magnet.

Further, referring to FIG. 2, each cross-sectional shape will be described. The small pipe 7 is a square pipe having a concave middle portion, and the tip end side connecting means 4b is slidably inserted into the upper portion thereof. Further, a tip side 4e is slidably fitted in the lower portion thereof, and a leaf spring 4h for urging the tip side 4e downward is inserted. Both the outer pipe 1a and the middle pipe 1b are formed in a rectangular shape.

The present invention is not limited to the above-mentioned embodiments, and the modifications listed below are also possible. (1) Each pipe has a rectangular shape. This shape has the advantage that it can be turned around by itself, and that the direction of the pole 1 can be easily determined when the saw S is attached to the tip side 1d for use. However, it may be circular, oval, or any other shape. (2) In this embodiment, by grasping the operating lever 2, the hand side connecting means 4a is pulled and the opening / closing tool 3 is closed. On the contrary, the hand side connecting means 4a is pushed to operate, and at this time The combining means 6 may be operated. (3) If the locking means 5 is provided with a concave-convex portion, its operation will be reliable, but it is also possible to press the two surfaces having a large friction to engage them.

[0012]

According to the present invention, even if the length of the pole is changed, the connecting means can be freely expanded and contracted, and the expansion and contraction of the connecting means can be restricted only by operating the operating lever to open and close the opening and closing tool. Therefore, there is an effect that the operation is easy and reliable, and the horizontal manufacturing can be easily provided at low cost.
