The female lock member is attached so as to be movable forward and backward and rotatable via a support member, and the other locked body supports a female lock member which is provided with a notch on the periphery for engagement with the engagement groove of the male lock member. Since it is attached so that it can move forward and backward through a member, and the tips of the pins and notches of both lock members face each other when locking, the female lock member is moved back and the lock pin is protruded, and then the female lock is If you restore it,
The female lock member can be engaged with the engagement groove of the lock pin, and therefore, the two locked bodies can be connected and separated more smoothly than the conventional locking means by tightening bolts as described above. Moreover,
Before locking, the lock pin can be retracted by operating the operation handle, and the operation handle can also be rotated in the direction of the object to be locked, so that it does not protrude to the side. This has the effect of not getting in the way of storage.

In addition, the support member of the male lock member is provided with a stopper against which the operating handle of the male lock member collides when the lock is locked, and a fitting groove for the operating handle, so that the operating handle can be reliably accommodated in the fitting groove when the lock is locked. , the lock pin can be prevented from returning, and furthermore, a protrusion for engaging the operating handle that bulges out in the backward direction of the male lock member is provided at a suitable location on the operating handle contact surface of the stopper, and furthermore, the operating handle rides on the protrusion. Since a tapered surface is formed to allow the lock pin to move, when the operating handle is rotated and the operating handle is attempted to ride on the protrusion, the lock pin, that is, the male lock member, will move back slightly due to the restriction of the female lock member. This has the effect that the male lock member and the female lock member are tightly engaged, thereby making it possible to strengthen the connection between the locked bodies.
