An exhaust assembly of a sanding device includes a first passage and an extension tube which are respectively defined in a hosing of the casing of the sanding device. The hosing has an inlet and an outlet. The first passage communicates with the outlet and inlet, and the extension tube extends from the hosing. The extension tube is engaged with an annular cover which communicates with the sanding pad and has an exhaust tube. A control valve is rotatably received in the first passage to block or ...

A sander comprised of a high voltage direct current motor for providing rotational torque to the sander is disclosed. In an exemplary embodiment, a motor housing generally encompasses the motor for enclosure of the motor. The motor housing being generally contoured to be received by a human hand and sized to a generally sized human hand. Further, a sanding assembly is operationally coupled to the motor housing for providing an abrasive surface to be used to sand a desired surface. The use of a v...

A vacuum-assisted pole sander includes a sanding means attached at the end of the main pole, which in turn is supported in its middle section by a support pole. Both the support pole and the main pole are hollow and adjustable in length. The vacuum is transmitted from the sanding means of the device through the main pole to the vacuum connector in the supporting pole such that a vacuum can be attached on to ensure dust removal during operation. The combination of the support pole and the main po...

There is provided a structure for use in a power driven tool (1) for collecting dust generated by the operation of the tool. The structure includes: an outer housing; a commutation motor (5) disposed within the housing and including a main shaft (6) which has a tip end and a commutator (7) on the main shaft; a pair of brush assemblies (29) radially disposed around, and in contact with, the commutator of the motor; and a dust collecting fan (9) mounted on the main shaft of the commutation motor. ...

The preferred embodiment of a rotary hand tool attachment is intended for coupling to a rotary power hand tool of the type that has a housing with a substantially cylindrical nose portion and a motor having an output shaft with a mounting coupling for receiving a drive shaft extending forwardly therefrom. The attachment includes a housing having an output shaft configured to drive a rotating tool, and an input shaft configured to couple with the drive shaft so that the motor output shaft, drive ...

A variable camber sanding board includes a generally planar and flexible sanding base, which is adapted to receive abrasive sheet material. A front frame is pivotably linked to a mid handle via a front pivot connection. The front pivot connection includes a pin passing through coaxial bores formed in the mid handle and front frame. A mid handle includes a slotted attachment member which is pivotably secured to a trigger link, forming a middle pivot connection. The trigger link is pivotably secur...

A polishing machine consists of a housing to which a handle is fastened pivotally. A motor is mounted in the interior of the housing such that an output end of the motor is fastened with a linking mechanism. Two reciprocating members are fastened pivotally with the housing such that the reciprocating members are actuated by the linking mechanism to engage in a linear reciprocating motion. Two rubbing members are fastened respectively with the two reciprocating members such that the rubbing membe...
