Abstract: A frame stand includes a board, an interface plate and a supporting rack. The board is mounted on a display panel. The interface plate pivotally connects the board by a first shaft. The interface plate rotates in parallel with respect to the board and form a first rotate angle. The supporting rack connects the interface plate and has a second shaft and a supporting member. The supporting member swings a second angle by using the second shaft as an axis. The second shaft selectively approaches or moves away from a working surface. The frame stand switches between a first state and a second state. In the first state, the supporting member and the first side of display panel rest on the working surface. In the second state, the supporting member and the second side of display panel rest on the working surface.

Abstract: A lift device includes a main body unit including a first board and two racks and a lifting unit. The two racks are separately and parallely configured on the first board in a first direction. The lifting unit includes a lifting board disposed on and parallel to the first board, and being slidable with respect to the first board in the first direction; and two abutting members disposed on the lifting board between the two blocks and each having an abutting block and a first elastic member, wherein the abutting block is slidable with respect to the lifting board in a second direction perpendicular to the first direction, and the first elastic member is disposed on the lifting board to abut against one end of the abutting block for enabling the other end of the abutting block to abut against the protruding portions.
