Abstract: Embodiments of this disclosure provide a data transmission method, a communication apparatus, a computer-readable storage medium, and a chip. The method includes: generating, by a first multi-link device, a management frame, where the management frame includes a receiver address, a transmitter address, and link indication information, and the link indication information indicates that the management frame is applied to at least one link corresponding to the link indication information; and sending the management frame to a second multi-link device on a link on which a station indicated by the receiver address or a station indicated by the transmitter address operates.

Abstract: The invention relates to the technical field of chargers, in particular to a charger comprising a plug and a base which are detachably connected. The plug is provided with sliding slots and a clamping piece. The base is provided with sliding rails corresponding to the sliding slots and a clamping plate corresponding to the clamping piece. When the plug is connected to the base, the sliding slots slide in along the sliding rails, and the clamping piece clamps the clamping plate.
