A drill press includes a base, a column, a table, a chuck, a drive member, a transmission unit, a safety guard, and an inspection structure. Thus, an operator can view and inspect the transmission unit mounted in the safety guard through the inspection structure to directly judge the rotation speed of the rotation shaft of the chuck by inspecting the engaging conditions of the belt wheels of the transmission unit without having to remove the safety guard to expose the transmission unit, thereby facilitating the operator manipulating the drill press and replacing the bits.

A reciprocating saw includes a main body, a blade holding device mounted on the main body, and a blade detachably mounted on the support seat of the main body by the blade holding device. The blade holding device includes a bushing, a slide, a sleeve, a positioning ball, a torsion spring, and a guide rod. Thus, the blade can be mounted on and detached from the support seat of the main body easily and conveniently by rotation of the sleeve, thereby facilitating the user replacing the blade.

The invention discloses a structure of cutting guide for table saw. The structure of cutting guide is provided on the worktable of table saw, with an appropriate distance is kept between the cutting guide and saw blade. The structure of cutting guide includes a alignment body, which has an accommodating space provided therein, and a pair of tracks corresponding to each other with front-and-back locations is provided inside the accommodating space for being mounted by an adjusting plate. The adjusting plate can be position-adjusted along the tracks. Besides, a mark is longitudinally provided on the adjusting plate, while a transparent cover is provided at the upper side of alignment body. Therefore, when cutting operation is performed on a workpiece, a referential baseline can be provided, so that the workpiece can be aligned with the saw blade through the referential baseline and ready for cutting.

A laser-guiding coordination device for a drilling machine has a C-base, two laser-line projectors oppositely and adjustably embedded inside the C-base. Each laser-line projector has a first adjuster, a second adjuster perpendicularly and rotatably mounted inside the first adjuster, and a laser generator accommodated inside the second adjuster to generate laser lines. By rotating the first and second adjusters, two laser-lines projected to a workpiece are moved in parallel or rotation to adjust and to define a precise laser mark without need for physically drawing lines on the workpiece.

A pneumatic nail gun has a body, a nail magazine, an actuating device, a trigger assembly and a push bar assembly. The body has a housing, a handle and a nail firing device. The actuating device is mounted between the housing and the handle. The actuating device has a channel, a piston rod, an O-ring and a first spring to provide a restitute force to the piston rod. The trigger assembly is attached to the body and has an inner cap pivotally attached to the body, an outer cap slidably attached outside the inner cap, an actuating lever pivotally attached inside the inner cap and a second spring. Accordingly, the outer cap can be moved to a lock position to keep the nails from being fired unintentionally, and the pneumatic nail gun is safe in use.
