摘要： A high-speed power tool has a housing for an electromotor, and a tool casing mounted on the motor housing. A finishing plate is mounted on the tool casing for movement relative thereto. The motor drives a transmission which includes a crank member having an eccentric portion connected to the finishing plate for imparting oscillatory motion to the latter. The arrangement for connecting the eccentric portion of the crank member to the finishing plate includes a bearing mounted on the eccentric portion of the crank member, and a sleeve surrounding the bearing and detachably connected to the finishing plate. Screws which are accessible from the exterior of the tool casing and of the finishing plate connect the sleeve to the finishing plate. The transmission includes two pulleys mounted on the output shaft of the electromotor and on the crank member, respectively, the pulley on the output shaft being bipartite, the two parts of the pulley being spaced by an interchangeable washer and urged toward one another by a screw so that tension of a V-belt trained about the pulleys can be adjusted.

摘要： A hedge trimmer has at least one moveable blade and a second blade. The second blade has trapezoidal teeth. The first blade has rectangular teeth which have a broadened end portion, but, contrary to the prior art, the teeth of the first blade are at least twice as long as those of the second blade. As in the prior art hedge trimmers, the broadest part of each tooth is defined by two juncture points, one on each side of the tooth. For additional safety, in accordance with the invention, the maximum distance between adjacent juncture points of adjacent teeth is 14 mm.

摘要： A power sander includes a casing bounding a space in which a sanding plate is mounted for cyclical motion in parallelism with a plane of a support surface of the sanding plate. A sanding element, such as sandpaper, is supported on and covers the support surface of the sanding plate, and a clamping arrangement clamps the sanding element to the sanding plate. The clamping arrangement is mounted on the sanding plate for pivoting between an engaging and an disengaging position, and is biased toward the engaging position thereof. An actuating arrangement is mounted in a transverse wall of the casing for displacement between a retracted and an extended position and is operative for abutting against and displacing the clamping arrangement toward the disengaging position thereof during the movement of the actuating arrangement toward the extended position thereof. The actuating arrangement has an actuating portion which is accessible from the exterior of the casing, and a cam portion which engages an abutment surface of the clamping arrangement during the displacement of the actuating arrangement toward the extended position. The actuating arrangement may be arrested at least in the extended position thereof to thereby retain the clamping arrangement in the disengaged position during the exchange of the sanding element. Air may be withdrawn from the space bounded by the casing so as to remove dust resulting from the sanding operation from the vicinity of the sanding plate.
摘要翻译：功率砂光机包括一个壳体，该壳体围绕一个空间，其中砂磨板安装成与打磨板的支撑表面的平面平行的循环运动。磨砂元件（例如砂纸）被支撑在砂光板的支撑表面上并且覆盖着砂板的支撑表面，并且夹紧装置将砂磨元件夹紧到砂纸板上。夹紧装置安装在打磨板上用于在接合位置和脱离位置之间枢转，并且朝向其接合位置偏置。驱动装置安装在壳体的横向壁中，用于在缩回位置和延伸位置之间移动，并且在致动装置朝向其延伸位置运动期间，用于抵靠和移动夹紧装置朝向其脱离位置。致动装置具有可从壳体的外部接近的致动部分，以及在致动装置朝向延伸位置移动期间接合夹紧装置的邻接表面的凸轮部分。致动装置可以至少在其延伸位置被阻止，从而在更换砂磨元件期间将夹紧装置保持在脱离位置。空气可以从由壳体限定的空间中取出，以便从打磨板附近去除打磨操作所产生的灰尘。
