The present disclosure relates to an engine-driven tool (1) comprising a rotatable work tool (2), an engine (4) that is arranged to propel the rotatable work tool (2), a shielding cover (8) for shielding the rotatable work tool (2), and a dust channel (11) that is formed between the shielding cover (8) and the rotatable work tool (2). A dust hose (14) is arranged to connect the dust channel (11) to a dust container (17) and an electrically driven fan (16) that is arranged to convey air from the dust channel (11) into the dust container (17) via the dust hose (14). The engine-driven tool (1) comprises an electrical generator (18) that is electrically connectable to the fan motor (26) and is arranged to be at least indirectly driven by the engine (4). The electrical generator (18) is furthermore arranged to generate an electrical current when driven, where said electrical current at least indirectly is arranged to propel the fan motor (26).

Pipe cutting machine

A pipe cutting machine comprises: rotary blades in a pair, with a plane at a right angle to a center line of a pipe, the rotary blades being arranged to face each other on both sides of a y axis in such a manner that blade edges of the rotary blades overlap each other in an x-axis direction; a straightforward driving mechanism that drives the rotary blades straightforward in opposite directions of a y-axis direction so as to make the rotary blades pass each other on the x axis and in the vicinity of the x axis; and power direction conversion mechanisms that move the rotary blades outwardly to get farther from the y axis for avoiding interference between the blade edges when the rotary blades pass each other on the x axis and in the vicinity of the x axis.

A cutting machine reduces cost increase associated with production equipment and has design flexibility for different types of batteries. A cutting machine for cutting a workpiece includes a cutting machine body including a cutting blade, a motor that drives the cutting blade, and a motor housing accommodating the motor, and an adapter including a body holder attached to the cutting machine body and a battery holder in which a battery to power the motor is installable.

SAW BLADE STABILIZER AND METHOD
20200078877 · 2020-03-12 · ·

A saw blade stabilizer is provided. The saw blade stabilizer includes a housing and a shaft at least partially within a cavity of the housing. A piston is connected to one end of the shaft. A mechanical wedge is connected to a second end of the shaft in the housing. A stabilizer contact element slideably receives a portion of the mechanical wedge. Movement of the piston slides the portion of the mechanical wedge within the stabilizer contact element and moves the stabilizer contact element in a first direction not in line with the movement of the piston.

A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved.
