The locking device with a built-in hook using the operation member as a push button pushes a push button having rack teeth, rotates an intermediate gear meshing with the rack teeth, and has a hook formed with a gear meshing with the intermediate gear. When locking and unlocking by engaging with the receiving tool, the push button is further pushed from the locked state to release the stopper mechanism, and the compression coil spring in the outer summoning cage is used to restore the force. The hanging tool is configured to be removed from the receiving tool while pushing the push button back to the indoor side.
Therefore, since it is configured to lock and unlock by one-touch operation of the push button, there is a certain effect in improving operability, but the compression coil spring is deformed by pushing the push button and unlocked by its restoring force. Since it is configured to return to the locked state, the operation may be uncertain or unstable due to fluctuations in the magnitude of sliding friction. For example, if the push button biased by the biasing force of the compression coil spring stops before returning to the unlocked position, the push button is pulled back to the unlocked state. There is a need to.
Moreover, since it is necessary to deform the compression coil spring in the outer summon basket, the stroke of the push button becomes larger, so that the push button protrudes from the inner summit basket to the indoor side (for example, patent) (Refer FIG. 8 (a) of the literature 1.).

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that the locking / unlocking operation by the push button can be performed reliably and stably, and the protrusion amount of the push button from the inner summit bowl to the indoor side is small. The object of the present invention is to provide a lock device with a built-in scissors that can be made clean and smooth because it does not become large.
