摘要： The invention relates to a powered reciprocating saw, in particular to a pruning saw. To simplify use of the saw a clamping mechanism is provided which holds an object in position while it is sawn. The clamping mechanism is mounted at the front portion 4 of the housing of the saw near the saw blade 20. The clamping mechanism comprises: a slide element 30 for sliding movement in cutting direction C of the saw blade, a supporting member 30; and a clamping arm 40 being rotatably mounted on the slide element 30, by means of a one way rotary clutch 42 such that the arm can freely rotate in one direction only, in which direction the clamping arm 40 moves towards the support member 30 to clamp an object therebetween in a clamping position below the saw blade for sawing it. When the saw is in use, it vibrates due to its reciprocating parts. Since the clamping arm 40 has a moment of inertia with respect to this axis of rotation of the one way rotary clutch 42, the oscillating movement is transformed into a stepwise, progressive rotational movement of the clamping arm which thereby closes automatically to clamp an object to be sawn.

摘要翻译：本发明涉及动力往复锯，特别涉及一种修剪锯。为了简化锯的使用，提供了一种夹持机构，其在被锯锯时将物体保持就位。夹紧机构安装在靠近锯片20的锯齿壳体的前部4处。夹紧机构包括：用于在锯片的切割方向C上滑动的滑动元件30，支撑部件30; 并且夹紧臂40通过单向旋转离合器42可旋转地安装在滑动元件30上，使得臂可以仅在一个方向上自由旋转，夹紧臂40朝着该方向朝向支撑构件30移动以夹紧它们之间的对象位于锯片下方的夹紧位置，用于锯切锯片。当锯被使用时，它由于其往复运动部件而振动。由于夹紧臂40相对于单向旋转离合器42的该旋转轴线具有惯性矩，因此摆动运动被转换成夹紧臂的逐步的，渐进的旋转运动，从而自动关闭以夹持物体被锯

摘要： A cyclone dust extractor 1 comprising a housing 3 defining a first cyclone separator 23 and a second cyclone separator 33 in series, a centrifugal fan 11 for producing cyclones within the cyclone separators 23,33 and a motor 9 for driving the fan 11, wherein at least one of the cyclone separators 23 has an inlet portion 27 and an outlet portion 31 which are separated by a wall 35. As a result, the outlet portion 31 of the first cyclone separator 23 can act as a third cyclone separator. Additionally, unwanted turbulence between the inlet flow and the outlet flow of the cyclone through the first cyclone separator 23 is avoided.
