Claims

[Scope of utility model registration request]

In a connecting device in which an engaging protrusion protruding from a first connecting member is fitted into an engaged hole drilled in a second connecting member to connect the two, the engaging protruding member is connected to the first connecting member. An inner cylinder protruding from the surface of the member, a rotating shaft installed at the tip of the inner cylinder in a direction perpendicular to the axis of the cylinder, a stopper whose base end is pivotally connected to the rotating shaft, and the tip of the stopper is rotated by an external force of the inner cylinder. A protruding biasing spring is fitted onto the outer periphery of the inner cylinder so that it can move forward and backward in the direction of the cylinder axis, and in the forward position, the stopper tip is stopped and locked on its own inner peripheral surface, and at the retreating position, the stopper is released from locking. The engaged hole includes a large diameter outer cylinder fitting hole formed on one side of the second connecting member, and a large diameter outer cylinder fitting hole formed on the other side of the second connecting member. A small diameter inner cylinder fitting hole is formed concentrically with the outer cylinder fitting hole and communicates with the large diameter outer cylinder fitting hole, and a small diameter inner cylinder fitting hole is provided at the boundary between the outer cylinder fitting hole and the inner cylinder fitting hole. The stopper is moved outward from the inner cylinder by locking the front end of the outer cylinder inserted into the outer cylinder fitting hole and moving the outer cylinder backward toward the inner cylinder as it advances into the inner cylinder fitting hole. A coupling device comprising: an outer cylinder locking wall surface that rotates to protrude to bring the stopper tip into elastic contact with the opening edge of the inner cylinder fitting hole.
