The application provides a wire SI performance test board for rapid docking, comprising a test mainboard, a plurality of test output interfaces are arranged on the front surface of the test mainboard, a first SMA interface is arranged on the upper side of the test output interface, a second SMA interface is arranged on the left side of the test output interface, a test input interface is arranged on the back surface of the test mainboard, the test input interface is provided with a first magnetic attraction assembly, the test mainboard further comprises a test input connector, the test input connector is provided with a second magnetic attraction assembly, one end of the test input connector is rapidly docked with the test input interface through the second magnetic attraction assembly and the first magnetic attraction assembly, and the other end of the test input connector is provided with a wire docking interface. The application can significantly improve the wire connection / detaching efficiency, is simple and reliable to operate, reduces interface abrasion, and has good adaptability.

The liftable tea basket assembly comprises a cover body, a lifting shaft and a tea basket, the lifting shaft penetrates through the cover body, a lifting button is arranged at the top end of the lifting shaft, the bottom end of the lifting shaft is connected with the tea basket, a first magnetic attraction piece is contained in the lifting shaft and close to the bottom end, and a second magnetic attraction piece is contained in the lifting shaft and close to the bottom end of the lifting shaft. A second magnetic attraction piece is contained in the position, close to the lifting shaft, of the interior of the cover body, the lifting shaft ascends to enable the tea basket to be separated from the beverage, and the first magnetic attraction piece and the second magnetic attraction piece can be attracted in the radial direction. The first magnetic attraction piece is arranged in the lifting shaft, the second magnetic attraction piece is arranged in the cover body, and the first magnetic attraction piece and the second magnetic attraction piece cannot make contact with the beverage, so that the quality of the beverage can be prevented from being affected, and corrosion of the beverage to the magnetic attraction pieces can be effectively avoided.
