A collar system for a dust extractor is provided including: a collar including a drill passage extending through the collar and an extension forming an internal passage that connects at one end with the drill passage, the extension being attachable to a housing of the dust extractor to enable the internal passage to connect to a suction passage of the dust extractor; and a cover mounted adjacent an entrance of the drill passage, the cover being moveable between a first position where it covers the entrance and a second position where is remote from the entrance, wherein the cover comprises at least hole that passes through the cover.

An engraving device includes a material processing platform disposed on a base frame and including suction holes and a pneumatic joint communicating with the suction holes; a gantry bracket disposed across both sides of the base frame; a spindle motor disposed on the gantry bracket; a processing bit operatively connected to the spindle motor; a dust collector disposed on the processing bit; and a driving mechanism operatively connected to the spindle motor and configured to move along the X-axis, Y-axis, and Z-axis.

A suction device for a handheld power tool that is adapted to be driven in oscillation and that is equipped with a gearbox extension housing for mounting of the suction device. The suction device having a body mounted on the gearbox extension housing of the handheld power tool via a mounting section and an air duct formed in the body, the air duct being delimited at one end by an air inlet and at an other end by an air outlet on which a suction apparatus or a dust exhauster is adapted to be detachably mounted. The mounting section of the body is formed essentially as a hollow cylinder and extends between a first plane and a second plane, which are substantially parallel.

An attachment (110) for a hand-held power tool (200), in particular a screwdriver or drill, wherein the attachment (110) has an attachment housing (113) and a drive element (123) on a drive side (111), which drive element can be coupled to a machine output element (221) of the hand-held power tool (200) in order to drive the attachment (110) and is firmly connected to an output element (120A) of the attachment (110) or is motion-coupled via a gear (530) in order to drive a working tool (242), wherein the attachment (110) has a fastening device (105) on the drive side (111) for detachable fastening to the hand-held power tool (200), wherein the fastening device (105) has at least one support surface (232) that is stationary with respect to the attachment housing (113) for providing support on the hand-held power tool (200) in the direction of a support axis (ST) and at least one locking body (150) adjustable between a locking position and an unlocking position and loaded into the locking position by a spring assembly (157).

The objective of the present invention is to provide a conveyor for discharging scraps of a laser notching machine. The present invention comprises: a conveyor (20); a suction duct (52) which is connected to the conveyor (20) so as to suck, from the conveyor, scraps (2S) generated when a tab (2C) is formed on a pole plate (2) passing through the conveyor (20); and a scrap discharge hole (34) for sucking and discharging the scraps (2S) from the conveyor (20), wherein the conveyor (20) includes: a conveyor body (22); and a conveyor belt (24) for performing a continuous track motion so as to pass the upper and lower surfaces of the conveyor body (22), wherein the conveyor body (22) has a vacuum sector (22VS) and a vacuum release sector (22RS), the vacuum sector (22VS) is configured to have a vacuum suction hole communicating from the inner space portion of the conveyor body (22) to the bottom surface of the conveyor body (22), and the scrap discharge hole (34) is disposed under the vacuum release sector (22RS).

A dust collector operable to collect dust and debris generated during operation of a power tool includes a mounting base configured to couple to the power tool. The mounting base defines a longitudinal axis. The dust collector also includes a shroud extending from the mounting base. The shroud includes a first end adjacent the mounting base, a second end operable to contact a workpiece, a sleeve extending between the first end and the second end, and a spring biasing the second end away from the first end.
