Abstract: An illuminating device includes an insulative housing, at least two electrodes and a light source. The insulative housing has opposite front and rear surfaces and is formed with at least two through holes. Each of the through holes is defined by a hole wall and penetrates the front and rear surfaces. Each of the electrodes includes a first conductive segment formed proximate the front surface, a second conductive segment formed proximate the rear surface, and a connecting segment formed inside a respective one of the through holes and interconnecting electrically the first and second conductive segments. The light source is disposed on the front surface and includes first and second connecting terminals each being electrically coupled to the first conductive segment of a corresponding one of the electrodes.

Abstract: A composite structure for an electronic device includes: a metallic base part made from a metallic material and having at least one bonding region; at least one porous protrusion made from a sintered metal powder and bonded to and protruding from the bonding region; and at least one feature molded over the porous protrusion.

Abstract: The invention related to a subsidiary vent channel of a nailing gun having a subsidiary vent hole at an internal plug of a rear cap. A subsidiary vent channel is disposed at a corresponding place of a rear cap. In this way, the compressed gas from the outside can be simultaneously injected into a nail-feeding air chamber of the gun body and the subsidiary vent channel. The gas injected into the nail-feeding air chamber serves for nailing. The gas injected into the subsidiary vent channel is available for different purposes.

Abstract: A firing mechanism of a nailing machine with a gun body and a nail cartridge having a telescopic safety member mounted on a front part of a gun barrel and coupled with a push bar within a fixing sleeve disposed at the bottom of a gas chamber whereby the displacement of the push bar permits a contact with a compression tongue of a trigger unit to proceed with a discharge process. An arched slot is correspondingly provided in a groove at both sides of the trigger unit. The compression tongue is pivotally connected to the trigger unit by a hidden displaceable pivot pin that is movable along the arched slot. The movement of the pivot pin along the arched slot of the trigger unit allows an adjustment of the contact area of the compression tongue to the push bar, thereby achieving a continuous discharge mode or a single discharge mode.

Abstract: A firing apparatus of a nailing gun with a gun body and a nail cartridge having a telescopic safety member mounted on a front part of a gun barrel and coupled with a push bar within a fixing sleeve disposed at the bottom of a gas chamber whereby the displacement of the push bar permits a contact with a compression tongue of a trigger unit to proceed with a discharge process. A three-stage longitudinal slot is correspondingly provided in a pair of side flanks of the trigger unit. The compression tongue is pivotally connected to the trigger unit through a pivot pin that is movable along the three-stage longitudinal slot whereby the movement of the pivot pin along the three-stage longitudinal slot of the trigger unit allows an adjustment of the position of the compression tongue relative to the push bar, thereby achieving three operating modes: continuous discharge, single discharge and out-of-action mode.

Abstract: The invention relates to a single-firing trigger mechanism for a nailing machine with a receptacle for receiving a swiveling element pivotably on a second positioning shaft. The other end of the swiveling element with a torsion spring is pivotally connected to a contact element on a third positioning shaft and, in addition, the top end of the contact element is disposed at a height to be in contact with a safety lever. The safety lever should be extended into the inside of the trigger and pressed against the contact element so as to be shifted in the direction of the firing pin. Thereafter, the user can press down the trigger again, thereby causing the contact element to be in contact of the firing pin for the next single-firing operation.

Abstract: The present invention relates to an air valve switch of an air brad nailer which includes a valve block, a valve shaft, a compression spring and two sealing rings. The valve block contains an axial through hole and a plurality of guide holes. A hindering rim is situated in the through hole so that the valve shaft can be plugged from the rear side of the through hole of the valve block into the front side thereof. Moreover, a thickened section rests against the hindering rim inside the through hole. And the compression spring is installed at the rear end of the valve shaft.

Abstract: A magazine for a rivet gun, generally comprised of a magazine body, a catch, a pusher, a stopper, a coil spring and a muzzle, wherein the magazine body includes a guide plate and a cover plate, the catch being controlled by the stopper and engaged with one end of the magazine body, a coil spring inserted at one end in the catch being able to apply the action of returning to its original form to move the pusher forward, thereby pushing the rivets along the pushing slot of the cover plate to the muzzle in an intermittent manner.
