PURPOSE: A locking device is provided to smoothly perform the forward and backward movement of a locking hook and the rotation of a handle by preventing frictional force between a housing and a tilting guide. CONSTITUTION: A pair of shells (110,110') forms a flange touching a cap and a case, includes a locking housing passing through one of hooking holes, and includes a lifting support block guiding the lifting of a locking hook (160) according to the rotation of a handle (170). A housing (120) is fixed with the shells to guide the operation of a tilting guide (150). The tilting guide is elastically installed in the housing with a wire spring to guide the movement of the locking hook. The locking hook is hooked on the hooking hole while moving in a right backward direction of the handle along the tilting guide in order to set locking. The handle is rotatably installed in the tilting guide to move the locking hook forward or backward. A lifting block (180) lifts up the locking hook moving forward by touching the hook according to the guide of the lifting support block. A restoring unit (190) touches the lifting block to the lifting support block and lifts down the locking hook and the tilting guide in order to restore the same. |
