Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a high branch, in which scissors are attached to the tip of a long handle, and an operating portion for the scissors is provided at the rear end of the long handle to cut a stem of a fruit or a branch at a high place. Long scissors for use.

[0002]

2. Description of the Related Art Generally, long scissors of this type are operated by operating an operating lever provided on one end side of a tubular elongated handle so that the scissors provided on the other end side of the tubular elongated handle are rod-shaped. Remote control is possible via a driving force transmission member such as a wire or a wire, and it is possible to cut fruit branches or the like at a high place or at a distance.

By the way, the conventional operating lever at hand has a pair of fixed lever and movable lever, but as described above, these are operated only at one end side of the tubular elongated handle. It was something to do.

[0004]

[Problems to be Solved by the Invention] However, in the case where the long scissors are operated by the operation section at one place,
When cutting a relatively thick branch or a hard-branched branch, even if you apply force with both hands, the operability is poor and a large cutting force does not occur even if you apply force, finger pain and fatigue Is remarkable. Needless to say, the cutting force is reduced when only one hand is added.

Further, since the whole long scissors are supported at one point, the stability in use is not sufficient, and a large force is applied to the connecting portion between the driving force transmitting member and the operating lever. Problems such as remarkable wear occurred.

An object of the present invention is to provide long scissors for high branches, which solves the above problems.

[0007]

DISCLOSURE OF THE INVENTION Long scissors for a high branch according to the present invention have a scissors 4 composed of a fixed blade 2 and a movable blade 3 attached to the distal end of a cylindrical elongated handle 1 to form a cylindrical long scissors. The scissors 4 at the rear end of the shaku handle 1
A first operation lever 5 is provided, and the movable blade 3 and the first operation lever 5 are connected by a driving force transmission member 6 that is inserted into the tubular elongated handle 1, and the first operation lever 5 is opened and closed. The movable blade 3 is actuated by means of the first operation lever 5 with respect to the driving force transmission member 6 at a portion of the tubular elongated handle 1 which is separated from the rear end toward the tip side by a predetermined distance. A separate second operation lever 7 for applying a force in the same direction as the above is attached so as to protrude outward through an opening window 8 provided in the tubular elongated handle 1.

[0008]

When using the long scissors for a high branch according to the present invention, first, the first operating lever 5 is supported by one hand, and the second operating lever 7 is supported by the other hand. However, in this state, the stem of the fruit, which is the object to be cut, or the branch at a high place is inserted between the fixed blade 2 and the movable blade 3 in advance. Next, in this state, the cut object can be cut between the fixed blade 2 and the movable blade 3 by closing the first operation lever 5 and the second operation lever 7, respectively.

[0009]

As is apparent from the above description, since the long scissors for a high branch according to the present invention have the above-described structure and operation, the first operating lever and the second operating lever have their respective positions. As a result, a large cutting force that exerts sufficient operability is effectively added, and even a relatively thick branch or a hard material branch can be easily cut without causing finger pain or significant fatigue. Also, at the time of work, a stable posture of supporting the whole long scissors at two points can be taken, and the applied force is divided into two by each operation lever and transmitted, so the load applied to each connecting part is reduced, and the wear phenomenon occurs. Can be avoided in advance.

Further, for example, in the case of cutting an object at a relatively distant position, in the case of cutting an object at the position of the first operation lever or at a relatively close position. Can be selected at a convenient operating position, such as operating at the position of the second operating lever, which means that especially when climbing a tall tree or between a target and the operating part This is effective when the worker cannot move freely due to the presence of the above.

In these figures, reference numeral 1 denotes a long tubular handle made of a pipe material (in FIG. 1, the middle portion is omitted near the tip, but the length is about 170 to 190 cm). The tip of the shank 1 is modified so that its cross section presents a keyhole. Then, on one flat portion 1a, the base portion of the fixed blade 2 of the scissors 4 is attached by bolts, and from the other insertion portion, such as a wire or a rod inserted into the tubular elongated handle 1 The driving force transmission member 6 can be taken out. The tip of the driving force transmission member 6 is connected 11 to the base end of the movable blade 3 pivotally attached to the base of the fixed blade 2 so as to be opened and closed. The fixed blade 2 and the movable blade 3 of the scissors 4 are provided on the same side surface with a pinching body 2 for pinching these stems when cutting fruits such as apples and grapes.
Both a and the sandwiching body 3a are attached by screws 12 so as to be detachable.

A fixed grip portion 5a is provided at the base of the tubular elongated handle 1.
And a movable grip portion 5b, a first operation lever 5 is provided, and one fixed grip portion 5a has a mounting portion 5 formed at the tip.
While being fixed to the base end of the cylindrical elongated handle 1 via c, the other movable grip portion 5b is pivotally attached to the abdomen of the fixed grip portion 5a at the base portion. An end of the driving force transmission member 6 is connected to a bent portion of the movable grip portion 5b, and the movable grip portion 5b resists a spring 15 which is installed so as to freely act on the fixed grip portion 5a. It is urged to attract. The tubular elongated handle 1 is provided with a separate second member that is biased in the same direction as the first operating lever 5 with respect to the driving force transmission member 6 at a portion spaced from the rear end toward the front end side by a predetermined distance.
The operation lever 7 is attached.

More specifically, the bracket 16 is externally fitted to the tubular elongated handle 1 at a portion spaced from the rear end toward the tip side by about 40 to 60 cm by an insertion hole 18 formed in the bracket 16. The bracket 16 is integrally fixed to the tubular elongated handle 1 with bolts 17, 17. The bracket 16 has a bearing portion 16a that projects laterally at the center thereof and rotatably supports the second operation lever 7, and a bracket 16 that has a tubular elongated handle in the circumferential direction sandwiching the bearing portion 16a. It has a pedestal portion 16b to be attached to the No. 1 and an opening window 16c through which the second operation lever 7 is passed.

At a portion of the driving force transmitting member 6 facing the bracket 16, a short cylindrical locking portion 19 in a direction orthogonal to the length direction of the driving force transmitting member 6 in a horizontal plane is integrally formed. It is fixed. On the other hand, the second operation lever 7
Has a middle abdomen 7a that is gently curved in a V shape and is bent, and the base is bifurcated so as to sandwich the bearing 16a from both sides.
