Claims

[Scope of utility model registration request]

A bifurcated frame having a lock through hole and a guide through hole on its side surface, a rotating piece rotatably mounted within the bifurcated frame and provided with a lock hole, and a rotating lock attached to the bifurcated frame. The rotating lock mechanism includes a guide rod slidably passing through the guide through hole of the bifurcated frame, a lock through hole of the bifurcated frame connected to the guide rod via a connecting piece, and a lock through hole of the bifurcated frame connected to the guide rod via a connecting piece. a locking rod that is slidably inserted into the locking hole of the rotating piece;
It consists of a lock spring that urges the rotation lock mechanism in the locking direction, and a lock spring that engages with the guide rod is installed inside the bifurcated frame, and the rotation piece has a lock spring that biases the rotation lock mechanism in the locking direction. An articulation mechanism characterized by being provided with a protrusion that pushes away a spring.
