Abstract: A chassis includes an electronic device. The electronic device includes a box body, a fixed member, and a slidable member. The box body includes a first side plate. The first side plate includes a corresponding portion. The fixed member is fixed to the first side plate and includes a positioning structure. The slidable member is slidably arranged on the fixed member and includes a matching structure and a mismatch-proof structure. The mismatch-proof structure is arranged in the corresponding portion. The matching structure selectively matches the positioning structure to cause the mismatch-proof structure to be slidably arranged in the corresponding portion.

Abstract: A connecting module is provided, including a housing, a circuit board, a sliding member, a first guiding member, and a second guiding member. The housing has an inserting portion. The circuit board is disposed on the housing, and includes a first connecting port and a second connecting port. The sliding member is movably disposed on the housing. The first guiding member is disposed between the inserting portion and the first connecting port. The second guiding member is disposed on the sliding member and situated between the inserting portion and the second connecting port. Owing to the aforementioned structure, different electronic members can connect to the first connecting port and the second connecting port. The connecting module can therefore support different electronic members.

Abstract: A wheel rim processing device for conducting wheel rim boring process. The wheel rim processing device comprises a base platform, a plurality of locators, a plurality of grippers, and a cutter unit. The base platform allows the wheel rim to be placed thereon and has a central slot hole corresponding to the spoke portion formed thereon and a long slot hole corresponding to the annular portion. The cutter unit can conducting boring process to the spoke portion and the annular portion respectively through the central slot hole and the long slot hole. The scraps generated in the process will fall from the hollow portion of the wheel rim rather than be accumulated on the base platform, which prevents the scraps or residues accumulated on the base platform during the wheel rim positioning process and the boring process.
