Abstract: A table saw includes a workbench, a support frame, a cutting assembly, a mounting device, and a first lighting mechanism. The workbench has a workplane. The support frame is used for supporting the workbench. The cutting assembly includes a cutting element, where the cutting element is disposed at least partially above the workplane, and a drive device that drives the cutting element to rotate around a rotational axis in a cutting plane. The mounting device is disposed above the cutting element. The first lighting mechanism is disposed on the mounting device and generates a first lighting region toward the cutting assembly.

Abstract: A tool attachment device for assisting a power tool in performing nailing includes a shell assembly, a rocker, a connection device, a driving wheel, and a transmission assembly. A side of the shell assembly is formed with a hole passage. The rocker is partially placed in the hole passage and is rotatable in the hole passage. The connection device is connected to the rocker and rotates synchronously with the rocker. Nail feeding structures are formed on the driving wheel along a circumferential direction of the driving wheel. The transmission assembly is connected to the driving wheel and the connection device and is configured to drive the driving wheel to rotate unidirectionally. The transmission assembly is disposed between the connection device and the driving wheel.

Abstract: A power saw includes a base plate, housing, and spring. The base plate is configured to move along a workpiece, and includes a pivot mount and a first retaining member defining an arcuate slot. The housing is configured to receive a cutting tool, includes a pivoting member and a second retaining member, and has a center-of-mass located between the pivot mount and first retaining member. The pivoting member is engaged with the pivot mount to pivotably mount the housing thereto. The second retaining member is received in the slot to guide a pivot of the housing. The spring is engaged between the base plate and housing, and is exerts a spring force acting against the weight of the housing such that a resultant force is sufficient to enable engagement of the cutting tool with the workpiece.

Abstract: Methods of manufacturing a variety of circuit protection devices are provided as well as devices so manufactured. In an embodiment, a surface mount electrical device having a substrate and a pair of conductive electrodes connected to an electrical protection component for sensing current or voltage is provided. The method includes the steps of: (i) providing a substrate having a first surface and a second surface; creating a first and second aperture, plasma etching a through-hole, slot or bore through the substrate; (ii) depositing a conductive material on the substrate and through the apertures to form the electrodes, wherein the conductive material extends through the apertures and on the first and second surfaces of the substrate, respectively; and (iii) depositing the electrical protection component on the first surface of the substrate to electrically connect the electrodes.

Abstract: Embodiments of the invention relates to an electric tool, in particular a circular saw, jigsaw or milling machine comprising a housing and a shaping tool that can be installed in a dismountable and rotatable way in the housing and wherein a laser unit is installed on or in the housing, which is outfitted to project a reference line that runs in the plane of an object to be shaped between the two sides of the installed shaping tool in its working direction and of which at least one side runs in or very close to the plane of one side of the shaping tool and wherein the laser unit can project a further reference line that runs in the plane of the object to be shaped between the two sides of the installed shaping tool in its working direction and of which at least one side runs in or very close to the plane of the other side of the shaping tool.
