Hand-held power tool as well as axial holding arrangement and working element for such a power tool

An axial holding arrangement (80) for holding a working element (38) of a hand-held power tool (10) in respect to a tool shaft (36) of the power tool (10) in an axial direction extending parallel to a rotational axis (40) of the tool shaft (36), after releasable attachment of the working element (38) to a distal end of the tool shaft (36) in the axial direction,

• characterized in that the axial holding arrangement (80) comprises
• a first element (36;
• 38) constituted by one of the following elements, the working element (38) and the tool shaft (36), and a second element (38;
• 36) constituted by the other one of the elements, the working element (38) and the tool shaft (36), and
• at least one locking element (70) assigned to the first element (36;
• 38) movably in a radial direction between a retracted position, in which the at least one locking element (70) is retracted in the first element (36;
• 38), and a locking position, in which the at least one locking element (70) protrudes from the first element (36;
• 38) radially towards the second element (38;
• 36),
• at least one radial recess (66) assigned to the second element (38;
• 36), the at least one radial recess (66) being configured to receive part of the at least one locking element (70) when in its locking position and after attachment of the working element (38) to the tool shaft (36),
• wherein at least one of the at least one locking element (70) and the second element (38;
• 36) in, or around, or in and around the at least one radial recess (66), comprises a magnetic material, and
• at least one other of the at least one locking element (70) and the second element (38;
• 36) comprises the magnetic material or a ferromagnetic material,
• so that the at least one locking element (70) is automatically moved into and held in its locking position 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), thereby engaging with the at least one radial recess (66) and holding the working element (38) in respect to the tool shaft (36) in the axial direction.

A working element (38) of a hand-held power tool (10), configured for releasable attachment to a distal end of a tool shaft (36) of the power tool (10) in an axial direction extending parallel to a rotational axis (40) of the tool shaft (36) and further configured to be held in respect to the tool shaft (36) in the axial direction by means of an axial holding arrangement (80), after attachment of the working element (38) to the tool shaft (36) in the axial direction,

• characterized in that
• the working element (38) comprises a first element, wherein a second element makes part of the tool shaft (36), or the working element (38) comprises a second element, wherein a first element makes part of the tool shaft (36), and
• if the working element (38) is the first element, at least one locking element (70) is assigned to the working element (38) movably in a radial direction between a retracted position, in which the at least one locking element (70) is retracted in the working element (38), and a locking position, in which the at least one locking element (70) protrudes from the working element (38) radially towards the tool shaft (36), wherein at least one radial recess (66) is assigned to the tool shaft (36), the at least one radial recess (66) being configured to receive part of the at least one locking element (70), when in its locking position and after attachment of the working element (38) to the tool shaft (36), or
• if the working element (38) is the second element, at least one radial recess (66) is assigned to the working element (38), the at least one radial recess (66) being configured to receive part of the at least one locking element (70), wherein the at least one locking element (70) is assigned to the tool shaft (36) movably in a radial direction between a retracted position, in which the at least one locking element (70) is retracted in the tool shaft (36), and a locking position, in which the at least one locking element (70) protrudes from the tool shaft (36) radially towards the working element (38), when the at least one locking element (70) is in its locking position and after attachment of the working element (38) to the tool shaft (36),
• wherein at least one of the at least one locking element (70) and the second element (38;
• 36) in, or around, or in and around the at least one radial recess (66), comprises a magnetic material, and
• at least one other of the at least one locking element (70) and the second element (38;
• 36) comprises the magnetic material or a ferromagnetic material,
• so that the at least one locking element (70) is automatically moved into and held in its locking position 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), thereby engaging with the at least one radial recess (66) and holding the working element (38) in respect to the tool shaft (36) in the axial direction.
