Device for detecting fixation of stylus and intelligent interactive board

A device for detecting a fixation of a stylus, comprising:

• a first support;
• a switch assembly arranged on the first support;
• a magnet assembly, wherein a side of the magnet assembly being away from the first support is used to adhere the stylus;
• and
• an elastic assembly,
• wherein the switch assembly comprises a micro switch, the micro switch comprises a triggering button, the triggering button of the micro switch is arranged facing the magnet assembly, and the magnet assembly comprises a triggering part;
• the magnet assembly is movably connected with the first support, and the elastic assembly is arranged at a movable joint between the magnet assembly and the first support;
• responsive to the device detecting the stylus, the magnet assembly moves away from the first support under an impact of an adhesive force of the stylus, and the triggering part is not in contact with the triggering button;
• responsive to the device failing to detect the stylus, the elastic assembly causes the magnet assembly and the first support to be in a bonding state, and the triggering part is in contact with the triggering button.
