摘要： The hand-held power tool has a vibration-damped main handle. The hand-held power tool has a device for fastening the main handle to a main element configured so that when the main element moves out of a stationary position toward the main handle the main element swivels around at least one swivel axis so that it is guided along a trajectory that extends with a slant of at least 10° relative to a flat surface, which extends through a longitudinal tool axis and which has a surface normal oriented in a normal direction perpendicular to the longitudinal tool axis. As a result vibrations with a movement component perpendicular to the longitudinal tool axis are damped as well as vibrations that induce motion of the main element in the direction of the longitudinal tool axis toward the main handle.

摘要： A hand machine tool is equipped with a hammer mechanism, which has a hammer (1) that moves axially back and forth in a guide tube (2); a spring mechanism (4) is provided, which exerts a force on the hammer (1) and can set the hammer (1) into a movement toward a tool (3) that can be inserted into the hand machine tool. The hammer mechanism produces a very high individual hammering energy at a relatively low hammering frequency by virtue of the fact that after each impact, the hammer (1) is set into a motion counter to the force of the spring mechanism (4) in order to stress this spring mechanism and after the stressing of the spring mechanism (4), the hammer (1) is abruptly released again so that it flies toward the tool (3).
摘要翻译：一种手动工具装备有一个锤子机构，该锤子机构具有在引导管（2）中沿轴向前后移动的锤子（1）; 提供弹簧机构（4），其在锤子（1）上施加力并且可以将锤子（1）设置成朝向可插入手动工具的工具（3）的移动。锤击机构以相当低的锤击频率产生非常高的单个锤击能量，这是因为在每次冲击之后，锤子（1）被设置成与弹簧机构（4）的力相反的运动，以便应力该弹簧机构，并且在弹簧机构（4）的应力之后，锤（1）再次突然释放，使其向着工具（3）飞行。

摘要： A percussion mechanism for a repetitively hammering hand power tool in the form of a rotary hammer has a striker movable axially forward and backward in a guide barrel and imparting impacts directly and without any intermediate parts to an end section of a tool bit that is insertable into the hand power tool, a device that exerts pressure on the striker, by which the striker is capable of being set into a forward motion in the direction of the tool bit, a blocking element, with which the striker is blockable in its forward motion, and the striking frequency of the striker is adjustable by controlling the blocking time of the blocking element, so that the striking frequency of the striker depends on how long the blocking element blocks the forward motion of the striker.
