Claims (1)

[Claims for Utility Model Registration] 1. An upper cone and a lower cone fixed to the upper and lower ends of a rotating shaft passing through the metal fitting body are always maintained in a locked state by spring pressure, and protrude from the metal fitting body. A container connecting fittings attaching/detaching device capable of operating each of the cones in an open state by horizontally swinging an operation handle, the connecting fittings set in which the container connecting fittings are set in a predetermined position. a cone operating member that operates the lower cone of the container connecting fitting set in the connecting fitting setting mechanism and rotates the upper cone in the locked state to the open state; to lock the operation of the cone operating member, and
a locking member that is activated against a spring force to release the lock of the cone operating member upon contact with a corner caster at the lower end of the container seated on the connecting fitting setting mechanism; and a locking member that has been lowered onto the connecting fitting setting mechanism. A power generating member that is actuated by contact with a corner caster at the lower end of a container or a container connecting fitting attached to this corner caster, and a drive spring that is compressed or tensioned by the operation of this power generating member. a drive mechanism that drives the cone operating member by the spring force of the drive spring; a return spring that returns the cone operating member operated by the spring force of the drive spring to its initial position with a spring force weaker than the spring force of the drive spring; A container connecting fitting attachment/detachment device comprising: a stopper member that operates independently of a locking member and is capable of locking the cone operating member at an initial position. 2. The connecting fitting setting mechanism has a connecting fitting setting part that can set the container connecting fitting with the operation handle protruding in the longitudinal direction of the container; a width direction guide member that comes into contact with the lower edge of the container in the width direction or the container connecting fitting attached to the corner caster to regulate the widthwise position of the container; a longitudinal guide member for regulating the longitudinal position of the container by contacting a container connecting fitting attached to the lower end edge of the container in the longitudinal direction or the corner caster; the width guide member is a longitudinal guide member; 2. The device for attaching and detaching a container connecting fitting according to claim 1, wherein the container is raised to a position above the container, and the container is positionally restricted in the width direction and then in the longitudinal direction.
