スコピツク機構。 A grooved shaft with a plurality of grooves along the axial direction is provided on the outer peripheral surface, and a cylindrical telescopic boss consisting of a handle boss part and a fixing boss part is slidably engaged in the groove part of the grooved shaft. In the telescopic mechanism, a stopper plate is provided at the end of the grooved shaft opposite to the side on which the handle is disposed, facing the end face of the telescopic boss, and a cover is provided on the non-opposing face of the stopper. Drilling a hole in a part of the stopper plate facing the end face of the telescopic boss,
The opening end on the telescopic boss side of this hole has an outer diameter larger than the diameter of the hole protruding toward the boss end, and can be sheared by the shearing force at the opening edge generated when the telescopic boss moves toward the stopper plate. 1. A telescopic mechanism, characterized in that a pin portion is provided, and the pin portion is connected to the cover through the hole portion.
