Replaceable footpad structure for electronic device

Abstract

A replaceable footpad structure for electronic device has a shell, on which a hanging hole is configured. The footpad structure includes a rotary buckling assembly, a rotary knob and a pad body. The rotary buckling assembly has a seat plate, from which a bolt and an arm are extended. The seat plate is connected by passing through the hanging hole, and the arm is snapped in the shell by a rotary manner. The rotary knob has a threaded hole inter-engaged with the bolt, while the pad body is connected to the rotary knob. Thereby, under the circumstance without any aid of tool, the footpad structure can be dismantled from or assembled to the electronic device quickly.
