Abstract: An industrial computer structure includes a case (100), a lug assembly (300), and touch panel (400). The case (100) has an opening (101) and a side plate (110) disposed on one side of the opening (101). The case (100) receives a plurality of trays (140) arranged within the opening (101). The side plate (110) has an external side (111) facing out of the case (100). The lug assembly (300) includes a fixing base (310) connected to the external side (111) of the side plate (110), a frame (320) disposed on the fixing base (310), and a handle (330) connected to the frame (320). The touch panel (400) is disposed in the frame (320) and electrically connected an electrical line (410) in the case (100). The components in the case (100) can be controlled via the touch panel (400) and thus the industrial computer can be easily maintained.

Abstract: A hex wrench assembly includes a tubular body having a reinforcement protrusion extending radially outward from a mediate portion of the body. A plurality of passages are defined in the body and a plurality of recesses are defined radially in an outer periphery of the body. Each recess shares a common axis of respective one of the passages. The head of a hex wrench is inserted in the passage and the handle of the wrench extends out from the recess.
