US Patent 11957258 Top item holder

A top item holder is configured to be placed on top of a screen. The top item holder includes an anti-tilt device, at least one slider, a slide rail and at least one holder unit. The anti-tilt device is for preventing the top item holder from being relatively tilting with respect to the screen. The slide rail is disposed at a top of the anti-tilt device. The slider is slidably disposed on the slide rail and can slide in a sliding direction within a sliding travel. The holder unit is disposed on the slider. Thereby, top space of the screen can be effectively utilized, and relocation of the holder unit becomes more convenient.
