1. A rolling mechanism comprising:
a base;
a circuit module disposed on the base;
a roller module disposed on the circuit module and movable on the base, wherein the roller module comprises:
a roller; and
a shaft passing through and connected to the roller;

an encoding element disposed on the circuit module and electrically connected with the circuit module, wherein the shaft of the roller module is directly connected to the encoding element;
a limiting element disposed on the base, directly contacting the base and configured to support the roller module, wherein the limiting element is independent of the encoding element and spaced apart from the encoding element, and the limiting element has two protruding structures connected to the base, each protruding structure has a limiting space, the shaft is pivotally disposed on the limiting spaces; and
an elastic element disposed between the roller module and the encoding element, wherein the elastic element is propped against the roller module.
