Abstract: A flame adjusting device for a gas burning device includes a flame adjusting wheel securely mounted to a disk of a valve on a gas tank and a neck extends from a side of the flame adjusting wheel and a ring is mounted to the neck. A protrusion extends from the ring and is accessible for the users. When shifting the protrusion, the ring and the flame adjusting wheel rotate to adjust the gas released via the valve. When a user wants to change the volume of gas released via the valve, he/she holds the protrusion and rotates the flame adjusting wheel so that the disk of the valve is rotated while the ring is remained still.

Abstract: A ratchet tool includes a cartridge having one end engaged in a handle and having an orifice for rotatably receiving a gear of a sleeve. One or more tool members may be engaged in the sleeve for driving various kinds of fasteners. A ratchet device is engaged in the cartridge for controlling the driving direction of the sleeve relative to the cartridge. A pair of pawls are slidably received in a pair of channels of the cartridge and are biased to engage with the gear. The gear may be selectively disengaged from the gear to control the driving direction of the sleeve.

Abstract: A tool handle device includes a handle having a base and a cover pivotally secured to the base for enclosing the interior of the base. The cover includes one or more retainers for securing tool members to the handle. The base includes one or more spaces for receiving the tool members and a tool, such as a plier device, particularly a foldably plier device. The handle includes two end pieces, the base is secured between the end pieces. An opening is formed between the end pieces for receiving the cover. A block is secured to a driving stem for receiving tool bits.

Abstract: A camera includes a casing having an optical device disposed in the front portion and a film disposed in the rear portion. One or more image sheets are detachably securing to the middle portion of the casing and between the film and the optical device by magnetic members. The magnetic members of the casing or the magnetic members of the image sheets are different from each other for checking the image sheets at the correct position. The casing includes a window having an additional image sheet for checking whether the image sheets are at the correct position.

Abstract: A power supply plug structure for a notebook computer includes a housing, two elongated sheet-shaped connecting legs, and two conducting pieces. An operation space is formed in the housing and has two sides each defining a receiving recess. Two opposite pivot holes are each defined in the operation space. Each of the two connecting legs is pivotally mounted in the receiving recess and includes a rotation shaft having two ends each having a pivot axle received in the pivot hole of the housing. A drive gear is mounted on the rotation shaft, and a conducting hook is integrally formed on the rotation shaft. Each of the conducting pieces detachably contacts with the conducting hook when the two connecting legs are pivoted to a fixed position. A plurality of meshing driven gears each mesh with the drive gear of the rotation shaft of each of the two connecting legs.

Abstract: A faucet includes a tubular body having an open end with a filter member received in the tubular body and the filter member has an outlet defined through one of two ends thereof. The tubular body has a head member connected to the open end thereof and the tubular body has an engaging tube which is connected to the outlet of the filter member. The head has a separating plate through which two apertures are defined and the engaging tube communicates one of the apertures. A valve device is pivotably received in the head member and has a first hole and a second hole defined through therein which alternately communicate with the two holes of the head member by operating the valve device so that the water filtered by the filter member flows from the first hole and the water not filtered flows from the second hole.

Abstract: A tool includes a handle having one or more orifices formed in one end for receiving tool members and having a peripheral groove communicating with the orifices for allowing the users to view and to obtain the required the tool member. The handle includes one or more chambers and one or more cavities communicating with each other for receiving tool members. A driving stem is secured to the handle for driving the tool members. A telescopic tube is further engaged in the handle and has a magnet extendible to attract the tool members. A door may enclose the chamber of the handle.

Abstract: A pumping device includes a main body having a passage defined therein and communicated with an air source. A retainer is slidably received in the main body and includes a chamber communicated with the passage of the main body. A nozzle is received in the chamber of the retainer and includes a nozzle passage communicated with the chamber. A plastic nozzle head is securely mounted in the main body and includes a valve chamber defined therein and communicated with the nozzle passage. A lever is provided for switching the retainer between a first inoperative position and a second operative position in which when the retainer is switched to the second operative position, the retainer exerts an inward force upon an outer periphery of the plastic nozzle head.

Abstract: A tool includes a handle having a bore for slidably receiving a stop and a link. The link has one end pivotally coupled to the stop for allowing the link to be rotated relative to the stop when the link is extended outward of the handle. A driving stem is pivotally coupled to the link for allowing the driving stem to be rotated relative to the link when the link is extended outward of the handle. A ratchet mechanism is disposed in the handle and is selectively engaged with the stop for controlling the driving direction of the driving stem.

Abstract: A portable put out device for cigarettes includes a heat-durable casing including an ash compartment and a butt compartment. A heat-durable meshy plate is mounted in the ash compartment. An upper lid is pivotally mounted to an open upper end of the casing. A heat-durable bottom plate is removably mounted to and thus encloses an open lower end of the casing. A carriage member is secured to the casing to allow the put out device to be attached to an article worn by a user.

Abstract: A dart board includes a score portion and a zero zone, the zero zone having a plurality of apertures defined by longitudinal ridges and latitudinal ridges, each of the longitudinal ridges and latitudinal ridges has two inclined surfaces defined in two sides thereof so that when the dart hits the ridges, the tip of the dart will be guided into the apertures.
