摘要： The invention refers to a plate-like backing pad (20) adapted for releasable attachment to a hand-held polishing or sanding power tool (2). The backing pad (20) comprises a center axis (34), a top surface (50), a damping layer (52) made of resilient plastic material and attached to the top surface (50), an even bottom layer (22) attached to a bottom surface (56) of the damping layer (52) and adapted for releasable attachment of a polishing or sanding member (24), and an attachment member (38) provided on the top surface (50) and adapted for releasable attachment to a corresponding attachment element (32) of the hand-held power tool (2), in particular of a tool shaft (28) or an eccentric element (30) of the hand-held power tool (2). It is suggested that the top surface (50) of the backing pad (20) has a central region (58) extending around the center axis (34) and an external region (60) surrounding the central region (58), that the central region (58) is recessed in respect to the surrounding external region (60), and that the attachment member (38) is provided in the recessed central region (58) of the top surface (50) with the center axis (34) extending through the attachment member (38) and at least part of the central region (58) surrounding the attachment member (38).

摘要： The invention refers to power tool (10) comprising a tool housing (12), a motor (24) located therein and a tool shaft (36) with a rotational axis (40) and actuated by the motor (24) when in operation. A distal end of the tool shaft (36) is accessible from outside the tool housing (12). The power tool (10) further comprises a polishing pad (38) releasably attachable to the distal end of the tool shaft (36) from outside the tool housing (12) in an axial direction parallel to the rotational axis (40) and, after attachment to the tool shaft (36), held in respect to the tool shaft (36) in the axial direction by means of an axial holding arrangement (80). The axial holding arrangement (80) comprises a first element (36; 38) constituted by the polishing pad (38) or the tool shaft (36) and a second element (38; 36) constituted by the other one of the tool shaft (36) or the polishing pad (38), and at least one locking element (70) held in the first element (36; 38) movably in a radial direction between a retracted position and a locking position, at least one radially extending recess (76) provided in the second element (38; 36) and configured to receive part of the at least one locking element (70) when in its locking position. The locking elements (70) and the second element (38; 36) in and/or around the at least one radial recess (76) are made of a magnetic or ferromagnetic material so that the locking elements (70) are automatically held in their locking positions and in the at least one radial recess (76) by magnetic force.

摘要： The invention refers to hand-held power tool (10) comprising a tool housing (12), a motor (24) and a tool shaft (36) having a rotational axis (40) and actuated by the motor (24), and further comprising a working element (38) releasably attachable to the tool shaft (36) from outside the tool housing (12) in an axial direction and, after attachment to the tool shaft (36), held in respect to the tool shaft (36) by means of an axial holding arrangement (80). The axial holding arrangement (80) comprises a first element (36; 38) constituted by one of the working element (38) and the tool shaft (36) and a second element (38; 36) constituted by the other one of the working element (38) and the tool shaft (36), and at least two locking elements (70) assigned to the first element (36; 38) movably in a radial direction between a retracted position and a locking position, at least one recess (66) assigned to the second element (38; 36) for receiving the locking elements (70) when in their locking positions. The locking elements (70) or the second element (38; 36) in and/or around the at least one radial recess (66) comprises a magnetic material and the at least other one of the locking elements (70) and the second element (38; 36) in and/or around the at least one radial recess (66) comprises a magnetic material or a ferromagnetic material. The locking elements (70) are automatically moved into and held in their locking positions and in the at least one radial recess (66) by means of magnetic force after attachment of the working element (38) to the tool shaft (36).

摘要： A hand-held electric power tool comprising an elongated tool housing, that supports an electric motor, and a moveable backing plate protruding externally from the tool housing. The electric motor actuates the backing plate, and the backing plate performs a rotational, random-orbital, orbital or gear-driven working movement in its plane of extension. A bottom surface of the backing plate detachably holds a polishing or sanding member. The tool housing has a rear part formed to be gripped by a hand of a user of the power tool thereby holding the power tool during its intended use and a tubular front part from which the backing plate protrudes, the front part having a smaller diameter than the rear part and being attached to the rear part. At least part of the electric motor may be accommodated in the tubular front part of the tool housing.
