Abstract: An auxiliary device includes a base, two rotatable arms, and an elastic member. The two arms are rotatably connected to the base and each includes a mating surface that defines a recess. The recesses of the two arms cooperatively form a through hole when the mating surface is in contact with each other. The through hole includes, from top to bottom, a first tapered hole portion, an annular groove, a second tapered hole portion, and a round hole portion. The annular groove is used to receive a head of a screw, and the round hole portion has a lateral surface is used to contact a shank of the screw to keep the screw upright. The elastic member is arranged between the two rotatable arms and applies a pushing force to the two rotatable arms.

Abstract: An assembling apparatus is disclosed. The assembling apparatus includes a base, an assembling platform, and a driving part. The assembling platform and the driving part are fixed on the base. The assembling platform defines a receiving space for receiving a semiconductor chip module, a lever chamber for receiving clips of the semiconductor chip module, and a driving groove for connecting the receiving space and the lever chamber. The assembling platform further includes a lever bar removably placed in the lever chamber for expanding the clips. The driving part includes driving shafts. An end of each of the driving shafts is in the driving groove and is movable to pass through the lever chamber and reaches the receiving space. The assembling apparatus is used to assemble a semiconductor chip module conveniently and safely.

Abstract: A hinge positioning apparatus includes a base, a first positioning unit, and a second positioning unit. The first positioning unit includes a load-supporting platform, a first locking mechanism, and a plurality of limiting blocks. The load-supporting platform is mounted on the base. The first locking mechanism is movable between a loose position and a locking position. The limiting blocks respectively mounted on the load-supporting platform and the first locking mechanism. The second positioning unit includes two coaxial supports and two second locking mechanism. The supports are mounted on the base adjacent the load-supporting platform, each defines a positioning groove in side surface facing the load-supporting platform. The second locking mechanism are mounted on the supports respectively, configured for maintaining hinges in the positioning grooves. The apparatus is used to position two hinges coaxially on an enclosure of a notebook computer.

Abstract: A screwdriver helper includes a handle, a guide, and a bit. The handle defines a through hole therein. The guide is affixed to the handle. The guide comprises a top surface, a bottom surface, and a through guide hole defined between the top surface and the bottom surface. The top surface is faced to the handle. The guide hole is corresponding to the through hole of the handle. An axis of the guide hole is perpendicular to the bottom surface. The bit is positioned in the guide hole. The bit comprises a tip and a head. The tip is in a shape of a screw head. The head defines slots in a top end thereof. The bit is movable along the axis of the through guide hole. The screwdriver helper helps screwdriver to lock screws firmly.

Abstract: A clamp tool for circuit board is disclosed. The clamp tool includes a frame, a handle, a plurality of gripping shafts, and a lock. The frame defines two vertical grooves facing each other. The handle is mounted on top of the frame. The gripping shafts are mounted beneath the frame, and include protuberant gripping heads on an end thereof. The lock includes a pull rod and a locking shaft. The pull rod passes through the vertical grooves and connects with the frame by elastic pieces. The locking shaft is mounted beneath the pull rod. The clamp tool is used to move circuit boards.

Abstract: A CPU mounting apparatus is disclosed. The CPU mounting apparatus includes a CPU receiver, two lever holders, two clips, two resilient members, a pair of levers, and a handle. The CPU receiver defines a cavity for receiving a CPU. The two clips are slidably mounted between the lever holders and the CPU receiver and include clip ends for holding the CPU. The resilient members apply resilient forces on the clips so that the clips can hold the CPU firmly. The levers are fixed on the lever holders and are positioned between the clips for pushing the clips to move. The handle is mounted on the lever holders above the levers for driving the levers to move. The CPU mounting apparatus is used to load/remove a CPU to/from a socket.
