Mouse

A mouse, comprising:

• a main housing;
• a key structure, having a connecting end, a free end, and an elastic section, wherein the connecting end is connected to the main housing, and the elastic section is located between the connecting end and the free end;
• and
• a pressing force adjusting component, movably disposed on the main housing and having a limiting portion, wherein the limiting portion limits elastic deformation of the elastic section, and a location of the pressing force adjusting component on the main housing is adapted to be changed to change a location of the limiting portion at the elastic section, wherein a distance exists between the connecting end and the free end, the distance is constant when the pressing force adjusting component moves along the main housing,
• wherein a first distance exists between a first location on the elastic section and the free end, a second distance exists between a second location on the elastic section and the free end, the distance is greater than the second distance, the second distance is greater than the first distance, and the pressing force adjusting component is adapted to move along the main housing to drive the limiting portion to move between the first location and the second location.
