Pressure sensing pointer

A pressure sensing pointer, comprising:

• a housing, having an accommodating space and a port, wherein the port is in communication with the accommodating space;
• an electromagnetic unit, located inside the accommodating space, and comprising a magnet and a coil, wherein the coil is wound outside the magnet;
• a cartridge, wherein the cartridge is movably disposed at the port of the housing along an axial direction;
• a pressing member, wherein the pressing member is movably disposed in the accommodating space along the axial direction, and is connected to the cartridge;
• a first elastic member, disposed inside the housing, wherein one end is fixed on the pressing member;
• a second elastic member, disposed inside the housing, wherein one end abuts against the pressing member, the other end is fixedly disposed inside the accommodating space, and an amount of compression deformation of the second elastic member in the axial direction is greater than an amount of compression deformation of the first elastic member in the axial direction;
• and
• a pressure sensing element, fixedly disposed inside the accommodating space, wherein the pressure sensing element faces toward the other end of the first elastic member.
