Pill grinder and method for using thereof

A pill grinder, comprising:

• a base plate;
• a guiding assembly connected to the base plate and comprising an elastic returning component;
• a handle component comprising a pair of handle connecting rods, wherein, a first connecting rod is connected to a first end of each handle connecting rod, the first connecting rod is movably disposed on the guiding assembly, a roller shaft is connected between the handle connecting rods, an axial direction of the roller shaft and an axial direction of the first connecting rod are both parallel to a first direction, the elastic returning component applies a force to the first connecting rod, for keeping the first connecting rod pressed towards the base plate;
• and
• a grinding component, sleeved outside the roller shaft, wherein, when the handle component rotates around the first connecting rod, guided by the guiding assembly, the grinding component has a grinding stroke along a second direction perpendicular to the first direction, for grinding at least one pill on a surface of the base plate to pill powders.
