Claims

[Scope of utility model registration request]

First and second rotating arms whose tips are biased in a direction protruding forward are pivotally supported on the main body. 2 connected by a link member to a rotating plate pivoted at the base end of the rotating arm.
The fingers are disposed in front of the fist so that they can freely appear and retract, the second rotating arm is formed with all fingers open, and the main body includes a push button and a push button protruding from the upper part of the main body. a drive mechanism consisting of a sliding rod whose upper end is fitted onto the push button and biased in the upward direction; and a lock that locks the first and second rotating arms that move downward in conjunction with the pressing operation of the push button. A cam having first, second, and third cam protrusions projecting to engage a stop mechanism and the upwardly moved sliding rod to stop it at a predetermined angle, and a cam that engages with the first cam protrusion. a release mechanism that releases the locking mechanism of the first rotating arm; a release mechanism that engages with the second cam protrusion to release the locking mechanism of the second rotating arm; and a release mechanism that engages with the third cam protrusion. A release mechanism is provided to release the locking mechanism of the first rotating arm, and a swing lever is provided that engages with the third cam protrusion to prevent rotation of the rotating plate connected to the two fingers. ”, “Pa”, and “Chiyoki” can be expressed selectively.
