摘要： A safety mechanism for a hedge trimmer is disclosed. Thumb catches 1032, 1048, together with corresponding locking members are initially biased downwardly relative to corresponding actuator levers 1010, 1014, as a result of which actuation of a motor of the hedge trimmer is prevented. This prevents inadvertent one-handed actuation of the hedge trimmer. In order to actuate the hedge trimmer, the user holds one of the actuator levers 1010, 1014 the corresponding thumb catch 1032 or 1048 upwardly, which causes movement of the other thumb catch towards its release position to allow pivotable movement of the actuator levers 1010, 1014 relative to a handle of the hedge trimmer. Movement of one of the actuator levers 1010, 1014 relative to the handle brings the lever 1018 into engagement with the electrical switch assembly 1008 to actuate the motor of the hedge trimmer. When the actuator levers 1010, 1014 are released, torsion springs urge the actuator levers 1010, 1014 and locking members outwardly relative to the handle housing 1004, as a result of which the locking members are urged into a locking position to prevent further actuation of actuator levers 1010, 1014 until the thumb catches 1032, 1048 have again been slid out of their locking position.

摘要： There is disclosed an actuation mechanism for actuating a power tool. The actuation mechanism comprises a cable assembly comprising at least one outer cable (41) arranged coaxially around an inner cable (40), wherein the inner cable (40) is adapted to slide axially relative to the outer cable (41). The actuation mechanism also comprises at least one electrical contact (42) connected to the cable assembly and a plurality of switch members (51, 54) connected to the cable assembly. In use, actuation of at least one predetermined one of the switch members causes the inner cable to move relative to the outer cable to close the electrical contact and actuate the power tool. By providing a coaxial cable assembly, having inner and outer cables connected to a plurality of switch members and arranged such that movement of the inner and outer cables relative to one another closes the electrical contact (42), this provides the advantage that a power tool with a two handed dual-switching mechanism can be actuated without the need for two independent electrical contacts wired in series, thereby reducing the amount of electrical wiring and components needed.

摘要： A handle assembly for a power tool is disclosed, in which the power tool has a housing, a motor provided in the housing, and an output shaft adapted to be caused by said motor to actuate a working member extending from the housing along a first axis (A-A). The handle assembly (102) comprises a front handle (106), a rear handle (107) integral with the front handle, and a mounting portion adapted to be mounted to the housing of the tool, wherein the front handle (106) forms an obtuse angle with the axis (A-A) of the working member in use. This last feature makes the power tool more comfortable for a user to operate, provided that the centre of mass of the power tool lies in the region between the front handle (106) and the rear handle (107). This will usually be the case, since the heaviest parts of the tool are generally the working member and the motor housing thereof. Thus the user does not have to stretch his forward arm as far relative to the rear handle (107) as he would have to do when using the handle assembly of a conventional power tool of this type.
摘要翻译：公开了一种用于动力工具的把手组件，其中动力工具具有壳体，设置在壳体中的电动机以及适于由所述电动机引起的输出轴，以致使沿着第一轴线从壳体延伸的工作构件（AA）。手柄组件（102）包括前手柄（106），与前手柄一体的后手柄（107）和适于安装到工具壳体的安装部分，其中前把手（106）形成与使用中的工作构件的轴线（AA）的钝角。如果电动工具的质量位于前把手（106）和后把手（107）之间的区域中，则最后的特征使得电动工具对于使用者来说更为舒适。这通常是这种情况，因为工具的最重部件通常是工作构件和其马达壳体。因此，当使用这种常规电动工具的手柄组件时，使用者不必像前后手柄（107）那样向前伸展远远的手臂。

摘要： A dog clutch for a power tool such as a chain saw for engagement and disengagement of the motor from the cutting tool comprising a first gear (32) mounted on and attached to a rotatable spindle (34), a second gear (36) rotatably mounted adjacent the first gear (32), and an engaging mechanisn (38) such as a cam ring. The second gear (36) is rotatably mounted on and axially slidable along the spindle and is biased preferably by a helical spring towards the first gear (32). The engaging mechanism (38) is rotatably mounted adjacent to and preferably about the second gear (36) in an axially slidable manner along the longitudinal axis of the spindle (34). The engaging mechanism (38) is configured so that rotational movement of the engaging mechanism (38) translates into an axial sliding movement. Rotational movement of the engaging mechanism moves the second gear (36) into and out of driving engagement with the first gear (32) depending on the direction of rotation.

摘要： A handle assembly for a power tool is disclosed, in which the power tool has a housing, a motor provided in the housing, an output shaft adapted to be caused by the motor to execute reciprocating motion, and a blade assembly (5) extending from the housing along a first axis (A-A). The handle assembly (2) comprises a front handle (6), a rear handle (7) integral with the front handle (6) and a mounting portion adapted to be mounted to the housing of the tool, wherein the rear handle (7) is displaced from the plane (A-A) of the blade assembly (5) in use. As a result of this, the knuckles of the hand of the user that is gripping rear handle (7) are raised away from the surface of the object being cut. This provides the advantage that the user's knuckles avoid any grazing or cutting resulting from contact with the object, or with the ground when carrying out low cutting.
