Abstract

An accommodating cylinder, a touch pen assembly, and a protective case are provided. The accommodating cylinder includes a cylinder body, a first magnetic member, a second magnetic member and a pen base. The cylinder body has an accommodating cavity. The first magnetic member is configured to generate a first magnetic field, and is arranged in the accommodating cavity. At least one of the first magnetic member and the second magnetic member is a coil, and the second magnetic member is arranged in the accommodating cavity and movable between a retracted position and an extended position. The pen base is connected with the second magnetic member. The second magnetic member is configured to move relative to the first magnetic member from the retracted position to the extended position, and to drive the pen base to move from an inserted position to a pop-up position in a first power-on state.
