• wherein the mounting seat comprises an upper housing and a lower housing which are detachably and fixedly connected, a receiving cavity is formed between the upper housing and the lower housing, and the wire spool is provided in the receiving cavity and is connected with the upper housing and/or the lower housing in a circumferentially rotating and axially fixed manner;
• wherein a secondary circuit board is connected to the upper housing or the lower housing and is located in the receiving cavity, the secondary circuit board is electrically connected to the main circuit board, and the output data cable is electrically connected to the secondary circuit board;
• wherein the wire spool comprises a planar portion, a support portion with a port, and a planar coil-shaped elastic portion, the elastic portion is placed in the port of the support portion, and an outer free end of the elastic portion is arranged in an elastic structure;
• and when the output data cable is wound over the support portion, the output data cable is in contact connection with the elastic structure;
• and
• wherein the support portion comprises a first arc-shaped section and a second arc-shaped section, a first gap and a second gap are formed between the first arc-shaped section and the second arc-shaped section, an outer free end of the elastic portion extends out of the first gap and is folded back into the port of the support portion via the first arc-shaped section and the second gap, the outer free end of the elastic portion is arranged in a protruding shape near the first gap and towards one side of the output data cable to constitute an elastic reset structure, and the elastic reset structure is in contact connection with the output data cable.
