Claims

[Scope of utility model registration request]

(1) In a mechanism that releases the lock between the rotating shaft and the housing by pulling out a pin, the rotating shaft is provided with a V-shaped groove, and the housing side is provided with a V-shaped groove facing the V-shaped groove. A groove in the shape of a key groove is provided, a sphere is placed in the V-shaped groove, and a lock release pin is placed to fix the ball, and after the pin is pulled out, the sphere is attached to the rotating shaft. A lock release mechanism characterized in that it is configured to be moved into the key groove-like groove by a torque component force. - (2) Practical use characterized in that a stopper is provided to prevent the sphere from interfering with the V-shaped groove of the rotating shaft again after the pin is pulled out and the sphere moves to the key groove-shaped groove on the housing side. A lock release mechanism according to claim (1) of patent registration.
