Abstract
A tool cabinet has a stand, a drawer frame, an upper case, multiple drawers and a locking device. The locking device is mounted in the upper case to keep the drawer from sliding out from the drawer frame. The locking device has a parallelogram four-bar assembly, an upper bar, at least one locking bar and multiple locking tabs attached to the drawers. The locking bar has multiple locking holes corresponding and engaging with the locking tabs on the drawer. Accordingly, the drawers can be held in place by the locking device to keep drawers from unintentionally sliding out from the cabinet. This can keep any person from being injured by the drawers, and the safety of using and transporting the cabinet is improved.
