Abstract: A central processing unit (CPU) assembly is disclosed having: a CPU; a socket removably receiving the CPU; a heat sink removably attaching atop the CPU; and a fastening device removably fastening the heat sink, the CPU, and the socket together. The fastening device is characterized by consisting: an elongated resilient body upon which a contacting surface is disposed for contacting the heat sink and pressing the heat sink against the CPU; two lever bars extending from opposite ends of the resilient body for exerting forces on the fastening device so as to fasten or remove the fastening device; and two latching arms extending from the ends of the resilient body for engaging the fastening device with the socket in an engage position, the latching arms in the engage position exerting an inward resilient force upon the socket at opposite sides thereof.

Abstract: The invention disclosed a mounting structure for supporting data storage device via sliding and securing mechanisms, wherein sliding rails and at least one securing hole are installed to each parallel side of the data storage device. The mounting structure comprises a case, one pair of sliding slots and at least one recess. The case serves as a container for the data storage device. One pair of sliding slots, formed at internal side of the case is arranged for the sliding rails of the data storage device to slide onto. The recess, formed at external side of the case, is next to an opening formed through the case thereof. When the data storage device slides in the case, the position of the opening is in line with the position of the securing hole thereof. As a result, the data storage device is mounted to the case through the opening and the securing hole with screws.

Abstract: A screw-less fixing structure is provided for users to mount the add-on card onto a PC. The screw-less fixing structure comprises a support plate, a rotational pressing plate, a positioning device, and a spring wire. When a user attempts to replace an old add-on card with a new one, he needs only to release the screw-less fixing structure by grasping and pulling the handling portion of the spring wire, replace the old add in card with the new one, and finally tighten the screw-less fixing structure by grasping and pushing the spring wire to reach the tightening state. In the above procedures for replacing the add-on card, the user does not need any additional tool nor screw so that the present invention has the advantages of safe, fast, easy and convenient to use.

Abstract: A receiving device is introduced for collecting goods such as CDs. The receiving device includes a cabinet and a storage element. The cabinet further comprises a fixing hole and the storage element further comprises a respective fixing rod with an inverted-V top for mating with the fixing hole. The storage element is located inside the cabinet while the fixing rod engages with the fixing hole. The storage element further provides a panel. While the panel rotates to disengage the fixing rod from the fixing hole, the storage element can be separated from the cabinet.
