Abstract: A prop stand includes a guide seat mounted to a rear side of an electronic device or a protective case thereof, a revolving seat rotatably assembled to the guide seat, and a propping unit movably connected to the revolving seat via a plurality of links pivotally connected to between the revolving seat and the propping unit. The links, the revolving seat and the propping unit together form a four-bar or five-bar linkage and a rotatable structure, such that the propping unit is movable by the links between a folded and an extended position and rotatable by the revolving seat to different angular positions relative to the guide seat. Therefore, the prop stand can be easily operated to conveniently prop the electronic product in a horizontally upright position, a vertically upright position or an inclined typing position. An electronic product protective case structure with the above-described prop stand is introduced.
