[0001]

[Industrial applications]

 The present invention relates to long scissors for a high branch, which has scissors 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 off stems of fruits and branches at high altitudes. Is.

[0002]

[Prior Art]

 Generally, this type of long scissors drives a rod or wire to drive the scissors provided at the other end of the tubular elongated handle by operating the operating lever provided at one end of the tubular elongated handle. It can be remotely controlled via the force transmission member, and it is possible to cut the branches of fruits at high places or at a distance.

By the way, the conventional operating levers at hand each have a pair of fixed levers and movable levers, but as described above, these are provided only at one position on one end side of the tubular elongated handle. It was something to operate.

[0004]

[Problems to be solved by the device]

 However, in the case of operating the long scissors with the operation part at one place like this, when cutting a relatively thick branch or a branch made of a hard material, even if force is applied with both hands, operability is The cutting force is not so great even if the force is bad, and the pain and fatigue of the fingers are 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. However, problems such as significant wear of members have occurred.

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

[0007]

[Means for Solving the Problems]

 The long scissors for a high branch according to the present invention has a scissors 4 composed of a fixed blade 2 and a movable blade 3 attached to the tip of a tubular elongated handle 1 and the scissors at the rear end of the tubular elongated handle 1. 4 is provided with a first operation lever 5, 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 cylindrical elongated handle 1, and the first operation lever 5 The movable blade 3 is actuated by opening and closing, and the tubular elongated handle 1 has a first operation with respect to the driving force transmission member 6 at a portion spaced 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 lever 5 is attached so as to project outward through an opening window 8 provided in the tubular elongated handle 1. Is.

[0008]

[Action]

 Therefore, 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. 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]

[Effect of the device]

 As is clear from the above description, since the long scissors for a high branch according to the present invention have the above-described configuration and operation, sufficient operation can be performed at each of the first operation lever and the second operation lever. As a result, a large cutting force that exerts the property is effectively added, and even a relatively thick branch or a hard-branched branch can be easily completed without causing finger pain or significant fatigue. Also, at the time of work, a stable posture that supports 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 connection part is reduced, The wear phenomenon can be avoided in advance.

Further, for example, when cutting an object located at a relatively distant position, when cutting an object located 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 tall trees or between a target and the operating part Therefore, the effect is produced when the worker cannot move freely.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 to 4 show one embodiment of the present invention. FIG. 1 is a partially cutaway front view showing the entire long scissors for a high branch according to the present invention, and FIG. 2 is a front scissor portion of FIG. 3 is an enlarged side view, FIG. 3 is an enlarged front view of a main part of FIG. 1, and FIG. 4 is a cross-sectional plan view taken along the line IV-IV of FIG.

In these figures, reference numeral 1 denotes a tubular long handle made of a pipe material (in FIG. 1, a 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, the base of the fixed blade 2 of the scissors 4 is attached to one flat portion 1a by bolts, and the wire or rod or the like inserted into the tubular elongated handle 1 from the other insertion portion. 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 blades 2 and the movable blades 3 of the scissors 4 are provided with screws 12 on both sides of the fixed blade 2 and the movable blade 3 for holding the shafts of the fruits when cutting fruits such as apples and grapes. It is attached so that it can be removed.

A first operation lever 5 including a fixed grip portion 5a and a movable grip portion 5b is provided at the base of the tubular elongated handle 1, and one fixed grip portion 5a has a mounting portion formed at the tip thereof. While being fixed to the base end of the cylindrical elongated handle 1 via 5c, the other movable grip portion 5b is pivotally attached to the abdomen of the fixed grip portion 5a at the base portion. The end of the driving force transmission member 6 is connected 14 to the bent portion of the movable grip portion 5b, and the movable grip portion 5b is attached to a spring 15 which is internally provided so as to act freely on the fixed grip portion 5a. It is urged to pull against. The tubular elongated handle 1 is provided with a separate second operation lever that is biased in the same direction as the first operation lever 5 with respect to the driving force transmission member 6 at a position spaced from the rear end toward the front end side by a predetermined distance. 7 is attached.

More specifically, a bracket 16 is externally fitted to the tubular elongated handle 1 at a site separated from the rear end thereof by about 40 to 60 cm toward the front end side through an insertion hole 18 provided 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 that rotatably supports the second operating lever 7, and a cylindrical elongated member 16a that surrounds the bearing portion 16a in the circumferential direction. It has a pedestal portion 16b for attaching to the handle 1 and an opening window 16c through which the second operation lever 7 is passed.

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

Opening windows 8 of a size large enough to allow rotation of the second operating lever 7 are provided on the left and right sides of the tubular elongated handle 1 at positions facing the bracket 16. Has been drilled. The base of the second operating lever 7 is pivotally attached to one side of the tubular elongated handle 1 by a bracket 16, which penetrates through the opening windows 8 and 8 to connect the first operating lever 5 to the second operating lever 5. In a normal state in which the second operation lever 7 is not attracted as indicated by the dashed line, the second operating lever 7 is also kept in a substantially horizontal posture in which it cannot be attracted by the biasing force of the spring 15 as shown by the alternate long and two short dashes line in FIG. A force in the same direction as the first operation lever 5 (clockwise force in FIG. 3) can be applied to the driving force transmission member 6.

Next, when using the long scissors for high branches, as soon as a stem of a fruit as a cut object or a branch at a high place is inserted between the fixed blade 2 and the movable blade 3, The first operating lever 5 and the second operating lever 7 are closed. That is, in synchronization with the closing of the first operating lever 5, the second operating lever 7 is rotated in the counterclockwise direction against the spring 15 so that the second operating lever 7 is changed from the two-dot chain line to the solid line state, and then the second operating lever 7 is closed. Of. That is, in this way, the second operating lever 7 is closed in this way so that the second operating lever 7 presses the locking portion 19 and the driving force transmitting member 6 is moved in the same direction as the first operating lever 5 via the locking portion 19. By closing the movable blade 3 by pulling it, the object to be cut which may be interposed between the fixed blade 2 and the movable blade 3 is almost cut by the doubled force. When the cutting of the object to be cut is completed, the force applied to the first operating lever 5 and the second operating lever 7 is released again, so that the first operating lever 5 and the second operating lever 7 are again in the two-dot chain line. Return to the state.

Although the embodiment of the present invention has been described above, the present invention can be modified within the scope of the invention. For example, when a particularly large cutting force is required, the length can be changed as necessary such that a larger cutting force can be obtained by sufficiently increasing the length of the second operating lever 7.
