Computer mouse having interchangeable modules adaptable to left/right hand use

A computer mouse having interchangeable modules adaptable to left/right hand use, comprising:

• a mouse body including a first joint portion and a second joint portion, wherein the first joint portion and the second joint are symmetrically arranged with respect to one another;
• a first input unit including a first base and a first button disposed on the first base, wherein the first base and the first button are arc-shaped, and the first button is configured to be depressed downwardly relative to the first base;
• and
• a second input unit including a second base and a second button disposed on the second base, wherein the second base and the second button are arc-shaped, and the second button is configured to be depressed downwardly relative to the second base;
• wherein a shape of the first base is corresponding to that of the first joint portion and a shape of the second base is corresponding to that of the second joint portion such that the first input unit and the second input unit are interchangeably respectively disposed on the first joint portion and the second joint portion;
• wherein the mouse body includes a processing unit disposed therein, the processing unit has a main resistor, the first input unit has a first divider resistor, and the second input unit has a second divider resistor;
• wherein, when the first input unit and the second input unit are interchangeably respectively disposed on the first joint portion and the second joint portion, the first input unit and the second input unit are electrically connected to the processing unit, and the main resistor, the first divider resistor and the second divider resistor are in series to correspondingly generate a divided voltage to the processing unit such that the processing unit determines a current operation mode to be a right-handed mode, a left-handed mode, or a normal mode according to the divided voltage;
• wherein the processing unit determines the current operation mode to be the normal mode when the divided voltage is a first divided voltage;
• wherein the processing unit determines the current operation mode to be the right-handed mode when the divided voltage is a second divided voltage;
• and wherein the processing unit determines the current operation mode to be the right-handed mode when the divided voltage is a third divided voltage.
