Abstract: A support rack includes a support plate, a support stand, a locking member, a pen holder, an indication member, and two auxiliary clips. Thus, the support rack functions as a clipboard, a book rack, an exhibition rack, a price indication rack, a pen holder or the like, thereby enhancing the versatility of the support rack. In addition, the support stand is adjustably mounted on the locking member so as to adjust the inclined angle between the support plate and the support stand, thereby facilitating a user adjusting the inclined angle of the support rack to the optimum extent.

Abstract: A holder includes a base having a disk and a combination seat, an elastic plate mounted on the disk and having a protruding elastic portion, a sucker mounted on a bottom of the disk and having a shaft extended through the through hole of the disk and the slot of the elastic plate, and an actuating handle having an enlarged head pivotally mounted on the shaft and urged on the elastic portion of the elastic plate. Thus, the holder is assembled and disassembled easily and conveniently, thereby facilitating the user mounting the holder. In addition, the holder is assembled rigidly and stably, so that the holder will not become loosened during a long-term utilization, thereby facilitating the user using the holder.
