Abstract: A fastening tool having a latch mechanism that performs a tool-free jam release of a jammed fastener in the nosepiece. The latch mechanism includes a latch plate that is secured to the nose portion of a nosepiece assembly by a latch member and is pivotably releasable from the nose portion by a user's fingers.

Abstract: A fastening tool having a depth adjustment mechanism mounted on a longitudinally movable door of a nosepiece assembly. The depth adjustment mechanism including a depth adjustment wheel having an internal threaded section extending along an axis and being rotatable about said axis; and an adjustment screw disposed within the depth adjustment wheel and engaging the door plate, the adjustment screw having an external threaded section that engages the internal threaded section of the depth adjustment wheel, so that a rotational movement of the depth adjustment wheel with respect to the adjustment screw effects a relative axial movement of the adjustment screw and the longitudinal movement of the door to increase and decrease the depth that a fastener is driven into a workpiece.

Abstract: A pneumatic tool has a body, a handle, a clip, a biasing member and a cap. The handle is formed on and extends from the body and has a free end and an annular shank extending from the free end. The clip is rotatably and slidably mounted on the shank and has a collar and a clip tab. The collar is rotatably and slidably mounted around the annular shank and has multiple teeth formed on a side of the collar facing away from the body. The clip tab extends from the collar. The biasing member is mounted around the annular shank and has two ends abutting respectively with the handle and the collar. The cap is detachably attached to the shank and has multiple recesses respectively corresponding to and engaging with the teeth on the collar.

Abstract: A nail gun has a body, a nail magazine, a pad supplier and a pad holding device. The pad holding device is mounted between the body and the pad supplier and has a base plate, an outer cap and a holding ring. The base plate is attached to the body, is connected to the pad supplier and has a pad channel and a holding hole. The outer cap has an outlet and a recess. The holding ring is C-shaped, is held inside the recess in the outer cap, aligns with the holding hole and has an inner diameter and an outer diameter. The inner diameter is slightly small than that of the holding hole to make the holding ring partially overlap with the holding hole to allow the holding ring to be expanded inside the recess.

Abstract: The invention discloses a drafting ruler that includes a straight ruler, a parallel ruler and a protractor, and the straight ruler includes a groove with a scale at the middle and an arc fixing groove using an end of the groove as the center. The protractor includes a semicircular protrusion corresponding to the fixing groove at the center of said straight ruler for movably connecting the straight ruler, such that the protractor can work with the groove of the straight ruler to draw an oblique line with an inclined angle, and can quickly draw several parallel lines or perpendicular lines starting from the mid-point to the length of the line by using the movably and perpendicularly connected straight ruler and parallel ruler, so that users can draw different figures or tables quickly and conveniently.

Abstract: A pneumatic nailer includes a magazine connected to the nose portion and includes two sidewalls between which a receiving space is defined so as to receive nails therein. A cover is slidably connected between the two sidewalls and a spring is connected to the cover so as to push a push plate movably located at an inside of the cover. A magnet is connected to the cover and magnetically attracts the push plate such that when the cover is pushed to close the magazine, the push plate is not move instantly with the cover. By this way, after the cover is moved to cover a part of the nails, the push plate starts to move to push the nails so as to prevent deformation of the wires connecting the nails.
