Abstract: A tool includes a body having an insert groove formed in and end surface for insertion of the processing member thereinto, a pressing block disposed within the body and abutting against an inclined surface of the body for pressing against the processing member, a controlling member connected pivotally to the body and rotatable about a pivot axis, and a connecting member connected fixedly to the pressing block and connected pivotally to the controlling member, in such a manner to allow the connecting member and the pressing block to rotate about a connecting axis. The controlling member is operable to rotate about the pivot axis to thereby rotate the pressing block about the connecting axis between a first position whereat the processing member is locked in the insert groove, and second position whereat removal of the processing member from the insert groove is allowed.

Abstract: A pneumatic nail gun includes a gun body, a connecting mechanism, an acting valve, a trigger, a safety valve, and a trigger valve. The gun body includes a safety compressed air inlet and a firing compressed air inlet. The connecting mechanism is slidably disposed on the gun body. The acting valve is connected to the connecting mechanism. The trigger is connected to the gun body. The safety valve is connected to the acting valve for allowing a safety compressed air coming from the compressed air source to drive the acting valve to move the connecting mechanism forwards when the trigger is pulled. The trigger valve releases a firing compressed air coming from the compressed air source to project at least one nail only when the trigger is pulled, a workpiece blocks the connecting mechanism, and the trigger opens the trigger valve.

Abstract: The present invention relates to a hook device which can be firmly positioned on a nailer, wherein a fastener is used to insert in the rear plug by cooperating with a ring-like hook, so as to make the rear plug slightly bulge out to press against the ring-like hook, thus, the ring-like hook is firmly fixed to the rear plug. The hook device can be arbitrarily and rotatably positioned on the nailer, wherein a plurality of positioning grooves are formed on the step circular wall of the rear plug, and a ring-like hook is mounted on the rear plug. The ring-like hook is provided with a positioning unit which is to be engaged in the positioning grooves of the rear plug, so as to enable the ring-like hook to be rotatably positioned on rear plug. Thereby, the user can position the nailer arbitrarily according to real needs.

Abstract: A poly lactic acid and veneer laminar structure, in which a poly lactic acid layer is adhered to one surface or two surfaces of a wood veneer, thereby preventing the wood veneer from easily splitting apart, wherein the poly lactic acid is a polymer, the raw material of which is natural cereal crops. Moreover, a food grade wrapping paper layer is adhered to one side or two sides of the poly lactic acid layers. Accordingly, containers fabricated from the aforementioned laminar structures are biodegradable, and provide environmental protection effectiveness with regard to natural ecology.

Abstract: A box, which is fashioned from wood chip, is applicable to goods or food packaging and can be converted into a gift box by a special design. The wood chip must be thick enough to be adaptable to a knife mold and pressed with a plurality of creases. Fold over the creases preformed on the wood chip so as to turn it into a cuboid receptacle.

Abstract: The present invention provides a structure of the inner head housing, which is placed inside the nail tip cover. The structure includes a movable base of the air-resistant ring, which is placed inside the slot of the fixed liner ring. The resilient component is used to support the movable base towards the direction of the cylinder under normal circumstances. The fixed liner ring is a single component; therefore, it is easy to process and make it smooth. The inner side of the nail tip cover does not need to be processed; therefore, it greatly reduces cost of processing and becomes more practical.

Abstract: The present invention relates to a screw-feeding device for a screw-driving tool comprising: a housing; a belt carrier is rotatably disposed in the housing and provided on the outer periphery with a plurality of teeth; a motion-transmitting member is disposed in the housing for driving the belt carrier to rotate unidrectionally; a guide rod assembly having a first free engaged with the motion-transmitting member and having a second free end used to rotate the motion-transmitting member; a positioning assembly pivotally is disposed in the housing for positioning the motion-transmitting member. The screw-feeding device is not only capable of feeding the screws precisely into the firing position, but also can hold the screws firmly.

Abstract: A screw bit replacing device for screw dispensers includes a main body having a passage defined therethrough in which a shaft is rotatably received. The shaft has a threaded recess defined in an end thereof so as to be engaged with a screw bit. A barrel has a tubular portion inserted in the passage and series of screws are sent in the barrel. A slot is defined through a wall of the tubular portion of the barrel and a plate is removably inserted in the slot. The plate has at least one aperture defined therethrough which is engaged with the screw bit so that when rotating the shaft, the screw bit is easily to be connected to or disengaged from the shaft.

Abstract: A screw feeding device includes a one-piece member composed of a gar, a hollow shaft and a positioning gear, a one-direction bearing received in the hollow shaft and a biasing plate contacting the positioning gear. The one-piece member reduces the space occupied by the parts of the device. An adjusting shaft has a serrated surface at one end to contact a safety board and a plurality of notches in the other end of the adjusting shaft, the notches are engaged with a bead biased by a spring, thereby controlling a depth of the screw that penetrates in an object. The guide body of the device is composed of two halves so that the manufacturing cost is reduced.

Abstract: A screw dispensing device includes a pushing member which is connected to the slide piece so as to simplify the processes of operation of the device. A movable positioning plate allows the screws with different sizes to be easily inserted in the barrel of the device. A rotatable adjusting knob is pivotably connected to the rear end of the positioning plate and controls the movement of the positioning plate so as to adjust the depth of feeding of the screws.
