Abstract

A roller wheel module includes a roller wheel, an elastic member, and an adjustment assembly. The roller wheel includes a ratchet structure and has a configuration surface. The configuration surface is divided into a blank region and a ratchet region. The ratchet structure is disposed on the configuration surface and is located in the ratchet region. The elastic member is disposed next to the roller wheel and has a first end and a second end opposite to each other. The first end of the elastic member is connected to the adjustment assembly, and the adjustment assembly drives the second end of the elastic member to move between the blank region and the ratchet region. The roller wheel module allows the user to switch between a ratchet rotating mode and a smooth rolling mode according to requirements, and allows the user to quickly scrolling and have a better touch feel.
