ることが知られており広く採用されている。2. Description of the Related Art Generally, tools such as cutting tools such as scissors and saws or tools such as holding tools are used for pruning and harvesting trees or fruits at a high place or at a distance, or for taking out objects located in narrow places. It is customary that the remote distance to the target object varies widely, but a so-called stretchable long pattern that can be operated by adjusting the length of the long pattern according to the degree is convenient. It is known and widely adopted.

できないため所望の最適長さに調節することが困難であ
る等の問題がある。As a method of adjusting the length of such a long handle, a pin-shaped one is inserted and fixed in a through hole formed at predetermined intervals along the longitudinal direction of the tubular long handle so as to be freely inserted and removed. There is a so-called stepped expansion and contraction fixing method, but as the number of steps increases, the number of through holes increases accordingly, so the strength of the long pattern itself decreases significantly, leading to shortening of product life In addition, there is a problem that it is difficult to adjust the length to a desired optimum length because fine adjustment cannot be performed during long / short stretch.

法が試みられている。In view of such circumstances, conventionally, a stepless expansion / contraction fixing method using so-called pressing friction using a taper sleeve or a cam mechanism, or a rack engraved along the longitudinal direction on the long handle itself, has been used. A stepless expansion / contraction fixing method using a so-called rack in which a stopper is engaged with and fixed to a rack has been attempted.

点からも好ましくない等の不都合な事態を生じる。However, the stepless expansion and contraction fixing method using the pressing friction of the former is susceptible to slip, not only requires a correspondingly strong pressing force, but also requires a different gripping force of the user. In addition to the difference in the pressing frictional force, there is a possibility that the fixing will be extremely unstable and uncertain due to the case where water or oil adheres to the frictional contact area or the frictional resistance decreases due to long-term use, etc. In the stepless expansion and contraction fixing method using a rack, the bulky long handle itself is integrally racked, which inevitably involves difficulties in processing and handling, resulting in a decrease in work efficiency and labor. In addition to the cost increase, metal pipes are often adopted from the viewpoint that the long handle is usually superior in strength, etc., but rack processing is performed on the metal pipe itself. When applying Requires a large thickness of which corresponds to the tube, this leads to increase in weight of the product itself, resulting in undesirable situations undesirable such as in terms of weight reduction.

Since it can be used even if it is divided into appropriate lengths, processing and handling are not bulky, it is extremely easy, it can be manufactured at low cost, and cost reduction can be achieved. Also, while the long handle tube is made of metal, other lightweight materials such as synthetic resin can be used for the rack bar, so that the weight of the product itself can be reduced while maintaining its strength. Even if the rack bar or a part of the rack bar is damaged, only the damaged part needs to be replaced, making it possible to recycle the entire long handle without deteriorating its value. In addition, since a long and short operation can be performed quickly and a compact reduced state can be achieved, there are many effects such as the fact that a long pattern that tends to be bulky can be made a convenient long pattern for carrying or storing.
