Multi-pressure-sensing identification capacitance pen and working method thereof

The invention discloses a multi-pressure-sensing identification capacitance pen and a working method thereof, and belongs to the technical field of capacitance pens, the multi-pressure-sensing identification capacitance pen comprises a pen body, the side wall of the pen body is provided with an induction sensor, the side wall of the induction sensor is provided with sliding holes which are oppositely arranged, the sliding holes are internally provided with limiting assemblies, the inner wall of the induction sensor is fixedly connected with an upper conductive disc, and the inner wall of the upper conductive disc is fixedly connected with a lower conductive disc. The bottom end of the upper conductive disc is fixedly connected with a conductive barrel; s1, adjusting the length of the pen point assembly; s2, switching the state of the disc type pen point; and S3, the state of the sharp and thin pen point is switched. By arranging the limiting assembly, the moving shaft, the limiting piece and the keeping press
