The invention relates to an arrangement for attaching a bar (1) of a hand-held motor driven tool, such as a chain saw, to a body (2) of the tool, the arrangement comprising at least one bolt (3), having a first part (3a), securely arranged to the body (2), and a second part (3b) extending from the body, the second part having an engagement portion (3c) for engaging a nut (5, 15), a cover portion (4, 14) adapted to bear against a bar (1) such that the bar is arranged between the cover portion (4, 14) and the body (2), and at least one nut (5, 15), captively attached to the cover portion (4, 14). The nut is adapted to engage the engagement portion (3c) of the bolt (3) for securing a bar (1) between the cover portion (4, 14) and the body (2), the nut (5, 15) having a rotation axis (X). The nut is also arranged to move a first distance (A) along the engagement portion (3c) of the bolt (3), in a direction of its rotation axis (X), for securing a bar (1) between the cover portion (4, 14) and the body (2). When the bolt (3) and the nut (5, 15) are not engaged, the nut (5, 15) is captively attached to the cover portion (4, 14) in such a way that it is movable a second distance (B) relative the cover portion (4, 14) in a direction of its rotation axis (X), wherein the second distance (B) is larger than the first distance (A).Thereby, an attachment arrangement is achieved that facilitates changing of bars when the nut used in the attachment arrangement is captively arranged to the cover portion. |
