Abstract: A tool case has multiple side plates, a bottom plate, an upper cover and multiple side covers. The side plates are connected with each other to define a containing space for storing large tools. Multiple recesses are defined in the outer side of each respective side plate for receiving tools. Each side cover is pivotally connected to one of the side plates and has an inner side with multiple recesses to receive tools. Accordingly, the space for storing tools in the tool case is large and many, and the use of the tool case is versatile.

Abstract: An adjustable driving tool includes a handle and a driving rod. The handle has a limiting portion disposed in the handle and a slot. The limiting portion has an inner space communicating with openings of a first sleeve portion and a second sleeve portion. The slot communicates with the inner space. The handle provided with a pin disposed through the inner space, and the first and second sleeve portions are disposed around the pin. The driving rod has a working end and a fixation end having an elongate through hole around the pin. The fixation end is disposed into the inner space through the slot. The driving rod is slidable relative to the pin, and the fixation end is controllably selectively inserted into the first sleeve portion or the second sleeve portion so that the driving rod is held.
