带有工作装置附件的动力工具
摘要：
一种便携式动力工具，其包括设置有用于手动支持工具的柄部(11)的壳体(10)以及驱动连接至输出轴(17)的旋转马达。连接装置(19)旨在将工作装置附接至输出轴(17)，并且包括锥形插座部分(25)和工作装置锁定筒夹(28)，所述锥形插座部分(25)与输出轴(17)一体形成并且与输出轴(17)共轴，其中，筒夹保持套筒(29)通过螺纹连接(30)支承在输出轴(17)上，并且具有内侧径向凸缘(24)，所述内侧径向凸缘(24)限定用于引入工作装置的前部开口(27)。螺纹连接(30)旨在使保持套筒(29)能够轴向移动，并且使得保持套筒(29)通过凸缘(24)在筒夹(28)上产生轴向推力。凸缘(24)的前部开口(27)的直径(d1)大于筒夹(28)的内直径(d2)。
摘要（英）：

A portable power tool comprising a housing (10) provided with a handle (11) for manual support of the tool, and a rotation motor drivingly connected to an output shaft (17). A connection device (19) is intended for connecting a working implement to the output shaft (17) and comprises a conical socket portion (25) formed integral and coaxially with the output shaft (17) and a working implement locking collet (28), wherein a collet retaining sleeve (29) is carried on the output shaft (17) via a thread connection 30 and has an inner radial flange (24) defining a front opening (27) for introduction of a working implement. The thread connection (30) is intended to enable an axial displacement of the retaining sleeve (29) and to make the latter produce an axial thrust force on the collet (28) via the flange (24). The front opening (27) of the flange (24) has a diameter (d1) that is bigger than the inner diameter (d2) of the collet (28).
