  • Patent number: 8733854
    Abstract: A cabinet with electrical locks forms a first through hole larger than a diameter of a horizontal rod for manually lifting a longitudinal track to unlock. A second through hole larger than a diameter of a pivoting arm for lifting the longitudinal track mechanically is also formed. Thereby, the first and the second through holes provide excess space for the horizontal rod and the pivoting arm, so the horizontal rod and the pivoting arm may not interfere each other when driven to lift the longitudinal track up. Thus, the pivoting arm may not be damaged when the longitudinal track is lifted manually.
