[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to high branch scissors in which scissors supported at the tip of a tubular elongated handle are opened and closed by an operating lever at hand, the tubular elongated handle having the scissors at the tip. The front pipe body supported and the rear pipe body provided with the operation lever at the rear end are separately formed, and the front pipe body and the rear pipe body are connected to each other so that the distance between them can be adjusted. The present invention relates to a highly expandable and scissor scissors in which the length of a handle is adjustable.

[0002]

2. Description of the Related Art Conventionally, high branch scissors are operated by operating an operating lever provided on one end side of a tubular elongated handle so that scissors provided on the other end side of the tubular elongated handle can be attached to a rod, a wire or the like. It is possible to remotely cut the branches of fruits or the like at a high place or at a remote place by remotely controlling them through the driving force transmission member. It is well known that such high branch scissors are so-called expandable and retractable high branch scissors that can be operated on the ground by adjusting the length of the tubular long handle depending on the degree of distance to the object to be cut. There is.

By the way, as a conventional high-pruning scissors of this kind, for example, Japanese Utility Model Laid-Open No. 80333/1992, that is, FIG.
As shown in FIG. 2, the cylindrical elongated handle a and the driving force transmitting member b are
Both of the members are divided into two or more constituent bodies, and the pipe-shaped constituent bodies of the tubular elongated handle a are connected by a relay body c so as to be detachable. That is, the pressing lever d attached to the relay body c
Through the through hole e provided in the tubular elongated handle a, while facing the movable lever f rotatably supported in the tubular elongated handle a, near the tip of the movable lever f. There is provided a structure in which the provided projection g is removably engaged with a through hole h formed in the structure of the driving force transmission member b so that the length of the handle can be adjusted.

[0004]

However, when the movable lever f is rotated, X = R (COSθ ₁ -COSθ is applied to the driven rod which is a component of the driving force transmission member b.
_It becomes necessary to form an extra large hole by an amount corresponding to ₂ ). As a result, rattling occurs between the protrusion g and the driving force transmitting member b, and due to the large perforation, the driving force transmitting member b.
The strength of the body itself is weakened, and the rattling also promotes the settling of the protrusions g and the like, which leads to further rattling and shortening of the life. Further, in the above-mentioned conventional technique, since the rotation preventing function is not provided, there is a drawback that the relative positions of the respective constituents of the tubular elongated handle a are displaced and accurate positioning cannot be performed, and the pressing lever d is also provided. Since it is arranged only on one side, the rattling of the tip with respect to the movement of the operating lever is accompanied by the fact that the load applied to the entire tubular elongated handle a cannot be balanced. This causes play in the movement of the scissors, which causes an inconvenient situation that hinders smooth operation of the Takaedashi scissors.

The present invention solves this problem, and when adjusting the length suitable for the distance to the object to be cut, it is extremely easy to detach and join the cylindrical long handle, driving force transmitting member, etc., and adjust the length. It is an object of the present invention to provide expandable and highly expandable scissors that can be quickly and quickly.
