Abstract: An improved structure of a CPU securing seat comprising a seat body, a covering body and a controlling device, characterized in that the seat body is provided with a plurality of triangular holes, and each of the triangular holes is provided with an inverted V-shaped clipping disc having securing legs extended from the bottom section thereof, the inverted V-shaped clipping disc is extended upward to the pore of the covering seat, and two lateral sides of the top section of the hole are extended to form a protruded rail and the covering body is provided with a plurality of triangular pores and one side of the pore is extended to form a notch, the bottom section of the pore is extended to form an engaging slot; the controlling device is mounted at the top section of the covering body to control the forward and backward movement of the seat body, thereby the controlling device is used to control the covering body to move backward so that the inverted V-shaped clipping disc is clipped by the notch to form an inve

Abstract: A track device for supporting a CPU in an extension port of a mother board, including a mounting frame fastened to the mother board at one side of the extension port and defining a vertical sliding track for guiding an inserted CPU into the expansion slot, and a support frame pivoted to the mounting frame and alternatively set between a collapsed position, a vertical position in vertical alignment with the vertical sliding track of the mounting frame for guiding an inserted CPU into the vertical sliding track of the mounting frame and the expansion port of the mother board, and stop means adapted to stop the support frame in position when the support frame it set in the vertical position.
