Abstract: Spool 1 for winding wire 2 comprising a hub 3, having a cylindrical external surface 4 extending around a main axis X-X, on which a channel 5 is afforded for guiding the wire 2 through the hub 3 terminating with a first hole 51 and a second hole 52. Three flanges 6,7,8 to define at least two chambers for winding the wire about the hub 3. Wherein the aforesaid hole 51 terminates with a respective terminal portion 9 made inside the cylindrical external surface 4.

Abstract: A portable sharpener for chains of chainsaws comprising sharpening means (2) and a coupling device (3). The sharpening means (2) are configured to sharpen the teeth (102) of a chain (101) of a chainsaw. The coupling device (3) supports the sharpening means (2) and is configured to be reversibly constrained to the chainsaw. Furthermore, the coupling device (3) comprises a support structure (4) which has a first plate (4a) adapted to be arranged parallel to a main extension plane of a chain guide bar (100) of the chainsaw and a second plate (4b) configured to abut against the bar (100), in such a way as to be at least partly interposed between the bar and the chain (101). The first and the second plate (4b) are arranged substantially in an L-configuration. The coupling structure further comprises one or more attachment members (5) applied to the first plate (4a) and configured to constrain the support structure (4) to the bar (100) of the chainsaw.

Abstract: A head (1) for a hedge trimmer comprising a main body (2), having a disc-shaped conformation, which can be connected to a drive shaft of a hedge trimmer to be placed in rotation about an axis of rotation (X). The main body (2) has at least one pair of primary seats (5) and one pair of secondary seats (6), each primary seat (5a) of the pair of primary seats (5) and each secondary seat (6a) of the pair of secondary seats (6) is a through seat. The pair of primary seats (5) is adapted to house a primary segment (S1) realised with a first cutting wire and arranged in a U-shaped arrangement between the primary seats (5a). The pair of secondary seats (6) is adapted to house a secondary segment (S2) realised with a second cutting wire and arranged in a U-shaped arrangement between the secondary seats (6a). Each primary seat (5a) of the pair of primary seats (5) has a primary transverse dimension (D1) and each secondary seat (6a) of the pair of secondary seats (6) has a secondary transverse dimension (D2).

Abstract: Cutting head for a hedge trimmer, comprising: a lower shell (2) and an upper shell (3), which are integral with one another with respect to the rotation around a rotation axis (X); two or more coupling pins (4), associated with the shells (2,3) and set up to enable respective cutting elements (B,W) to be coupled; the shells (2,3) are slidable in relation to one another along the rotation axis (X) between an operating position, in which they are alongside one another, and a change position, in which they are at least partially separated from one another; wherein the coupling pins (4), in the change position, have a free end (41) that is accessible to enable a cutting element (B,W) to be inserted or extracted; an elastic pusher (5) is provided that is set up for pushing the lower shell (2) and the upper shell (3) to the operating position.

Abstract: A trimmer head that includes a casing to be coupled to a driveshaft. The casing includes an upper shell and a lower shell, with the lower shell including a second toothing that protrudes upwardly. The trimmer head further includes an upper disk and a lower disk within the casing, with the lower disk including a first toothing that protrudes downwardly. A spool of cutting wire is positioned between the lower disk and the upper disk. In an engagement position, the first toothing and the second toothing are engaged and the upper disk and lower disk rotate with the lower shell. In a free position, the first toothing and the second toothing are disengaged and the upper disk and lower disk rotate with respect to the lower shell.
