The foot member is installed through the opening of the slider. One end corresponding to the foot member and the slider is respectively disposed a plurality of groove and a blocker. The top of the controller has an inclined part that presses against an inclined plane on one side of the slider. When a user presses the controller, the inclined part pushes the inclined plane of the slider, making the slider slide along one axis to make the blocker separated from the grooves in a parallel direction.
