PROBLEM TO BE SOLVED: To provide a device for fixing the adjustment position of a telescopic handle preventing the telescopic handle from causing malfunction and breakage due to deformation of fixing holes without varying the thickness of a thick tube and a thin tube in the vicinity of the positions of the fixing holes, and eliminating operation for strongly pressing an operation part: and to provide scissors and a saw each including the device.SOLUTION: The device for fixing the adjustment position of a telescopic handle is structured as follows: the thin tube is disposed inside the thick tube to be freely telescopic a plurality of thin tube-fixing holes are made at the peripheral surface of the thin tube in a longitudinal direction the operation part is formed in the vicinity of the tip of the thick tube and the operation part includes a plurality of engaging pins longitudinally set in lines and an elastic body biasing the engaging pins to the side of the thin tube-fixing holes, so that the thick tube and the thin tube are connectedly fixed to each other by engagement between the engaging pins and the thin tube-fixing holes. In the device for fixing an adjustment position of a telescopic handle, a plurality of the thin tube-fixing holes are formed so that the diameter of each of the thin tube-fixing holes on the tip end side of the telescopic handle is larger than the diameter of each of the adjacent thin tube-fixing holes on the back end side, and the engaging pins are placed in the thick tube-fixing holes in the condition of being disengaged from the thin tube-fixing holes.COPYRIGHT: (C)2011,JPO&INPIT【課題】太筒、細筒の固定用穴位置近傍の厚みを変更せず、固定穴の変形による伸縮柄の動作不良や折れを防止し、且つ操作部を強く押し込む操作を不要とする伸縮柄の調節位置固定装置とそれを備えた鋏及び鋸の提供。【解決手段】太筒の内側に細筒を配置して伸縮自在とし、細筒の周面には細筒固定用穴を長手方向に複数備え、太筒の先端近傍に操作部を備え、操作部は長手方向に列設する複数の係合ピンと該係合ピンを細筒固定用穴側へ付勢する弾性体を備え、係合ピンと前記細筒固定用穴との係合により太筒及び細筒を連結固定する伸縮柄の調節位置固定装置において、複数の細筒固定用穴は、伸縮柄の先端側となる細筒固定用穴の直径寸法が、隣り合う後端側の細筒固定用穴の直径寸法より大きく、前記複数の係合ピンが、細筒固定用穴との離脱状態で、太筒固定用穴内に配置される伸縮柄の調節位置固定装
