The invention discloses a novel tea packaging device. The device comprises a socket and a plug connected with the packaging device. An insertion column is fixedly installed on the plug. An annular groove is arranged in the periphery of the insertion column. An installation groove which is equipped with a downwards opening and matches the insertion column is arranged in the socket. A sliding rack which is capable of up-down sliding is installed in the installation groove. A power supply groove matching a conductive head is arranged in the base wall of the sliding rack. A power supply sheet is installed in the power supply groove. First sliding grooves which left-right extend and communicate with installation grooves are left-right symmetrically arranged in the inner wall of the installationgroove. Up-down extending second sliding grooves are left-right symmetrically arranged in the socket. The second sliding grooves penetrate through the first sliding grooves and have downwards openings. First sliding plates which are capable of left-right sliding are installed in the first sliding grooves.
