Chassis module without using securing tool

Abstract

A chassis module includes a chassis unit, a movable retaining unit and a switch unit. The chassis unit has a chassis body, at least one first retaining element on the chassis body and a movable cover separably disposed on the chassis body. The movable retaining unit is disposed on an inner surface of the movable cover, and the movable retaining unit has at least one second retaining element selectively cooperating with the first retaining element. The switch unit is assembled on the chassis body. The switch unit has a control portion exposed from the chassis body and a push portion connected to the control portion for selectively separating the first retaining element and the second retaining element from each other. Therefore, after operating the control portion to lift the movable cover up, a user can install or detach data access devices in/from the chassis body easily.
