    Abstract: A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism is disclosed. It can be used for an interior-typed or exterior-typed pulling rod mechanism. When it is the interior-typed condition, a locking plate is disposed near the top of the case. A lower receiving seat is disposed at the bottom inside the case for inserting the ends of the outer tubes. An upper cover seat is disposed on the outer tubes for locking or releasing from the locking plate. The engaging mechanism has two hooks and a button. So, by pressing the button, the user can control the pulling rod mechanism to lock on or release from the case. When it is the exterior-typed condition, the user still can easy control the pulling rod mechanism to be locked or released. Therefore, this invention's structure is simple. With destroying the case, its pulling rod mechanism can be quickly and easily exchanged.
