摘要： The combination of a) a first tubular element with a first axis, a first portion with a radially outwardly facing surface and a first connecting assembly with a first circumferentially facing surface and b) a second tubular element with a second portion with a second axis, a radially inwardly facing surface, and a second connecting assembly with a second circumferentially facing surface. The first portion is extendable within the second portion. The first and second tubular elements are movable around the first and second axes between a) a first relative rotational position and b) a second relative rotational position such that the first and second connecting assemblies cooperate to draw the first and second portions axially towards each other and the first and second circumferentially facing surfaces confront each other to thereby block relative movement back into the first relative rotational position.

摘要： A power source and a human contacting portion of a portable power tool, with a vibration-proof member and a spacer placed between them, are tightened by fastening and connecting means in the direction approaching each other. The spacer serves to limit compressive power of the vibration proof member which acts between the power source and human contacting portion within effective vibration-proof range of the vibration-proof member by utilizing the fastening and connecting means, This does not cause the vibration absorbing effect of the vibration-proof member to be lost. In addition, there is no need to check the fastening degree achieved by the fastening and connecting means, thus allowing easy attachment of the vibration-proof member thereto. Alternatively, vibration-proof members may be placed between the power source side and the working member side without spacers if the vibration proof members support the power source apart from the working member. To facilitate this construction a universal power transmission, such as a flexible shaft or coupling, is used to transmit rotation power from the power source to the working member in spite of a change in the relative positional relation of the power source to the working member, caused by the vibration-proof member.
摘要翻译：便携式电动工具的动力源和人体接触部分通过紧固和连接装置在彼此靠近的方向上被紧固和连接装置紧固，其中防振构件和置于其间的间隔件。隔离件用于通过利用紧固和连接装置来限制作用在电源和人体接触部分之间的防振构件的有效防振范围内的抗震功能。这不会引起振动吸收效应的防振构件会丢失。此外，不需要检查由紧固和连接装置实现的紧固度，因此容易将防振件附接到其上。或者，如果防振构件将电源与工作构件分开支撑，则防振构件可以放置在电源侧和工作构件侧之间而不具有间隔件。为了促进这种结构，尽管电源与工作构件的相对位置关系发生变化，但是使用诸如柔性轴或联轴器的通用动力传递装置来将动力从动力源传递到工作构件，由防振构件引起。
