Abstract: A foldable floss pick includes a grip having a first connection section at one end and a floss arch having a second connection section rotatably connected to the first connection section of the grip. A dental floss is connected between two ends of the floss arch. The floss arch defines a virtual face. When not folded, the floss arch is positioned in a first relative position where the virtual face is substantially coplanar with the grip and the floss pick is in a straight form to facilitate package. In use, the floss arch is first folded toward the grip and fixed in a second relative position by means of a latch structure disposed between the grip and the floss arch. Then a user can conveniently use the folded floss pick to clean the teeth.

Abstract: A PGA socket comprises a base, a cover slidably attached to the base, a lever and a slider. The lever is rotatablely coupled between the base and the cover to cammingly slide the cover and the slider relative to the base. A CPU having a plurality of terminals is inserted into the PGA socket. A heat sink is then attached to a top of the CPU. When the lever is rotated to a closed position, the cover slides to a closed position, electrically connecting the terminals of the CPU with the contacts in the socket. A pair of latch arms integral with the lever rotate from their open vertical position down between the fins of the heat sink to their closed horizontal position, and at the same time the cams of the lever actuate the slider to cammingly slide toward the heat sink thereby, effectively locking the heat sink into place.
