    • The invention relates to an adjustable-length tube (10) for poles, consisting of an external tube (12), an internal tube (11) that can be telescopically inserted into said external tube (12) to adjust the tube length and an expansion device (15) that is mounted at the insertion end of the internal tube (11) and is used to axially fix the internal tube (11) inside the external tube (12). Said expansion device comprises an expansion element (16), which is equipped with an inner cone (27) and can be radially spread, an internal element (17), which is equipped with an opposed cone (22) and is held in the expansion element (16) so that it can be axially displaced and an adjusting screw (18), which is positioned along the axis, is rotatably fixed to the internal tube (11) and co-operates with an internal threaded bore (21) in the internal element (17). In order for an adjustable length tube of this type to be fixed more tightly during impact-type axial stress, rather than shifting or giving way, the internal cone (27) of the expansion element (16) extends in such a way that it opens towards the internal tube (11) and the expansion element (16) is held between an inner stop (28) on the internal tube (11) and an outer stop (26) on the free end of the adjusting screw (18), so that it can be displaced within narrow limits.

    • The present invention relates to a tool coupling comprising a holder (1), an adapter (3; 3') for at least one cutting insert for chip removing machining and a separate element (5; 5') in order to detachably connect the holder (1) and the adapter (3; 3') with each other, said holder (1) being provided with a first serration (12), having mutually parallel grooves, and the adapter (3; 3') being provided with a second serration (16), having mutually parallel grooves. The invention also relates to the holder (1) and the adapter (3; 3') per se. It is significant for the tool coupling according to the present invention that the first serration (12) is located in a plane having an extension essentially perpendicular to a longitudinal centre axis (13) of the tool coupling, and that the second serration (16) is located in a plane having an extension essentially perpendicular to said longitudinal centre axis (13).
    • 本发明涉及一种工具联接器,该工具联接器包括保持器(1),用于至少一个用于去屑加工的切削刀片的适配器(3; 3')和用于可拆卸地连接保持器(5; 5')的单独元件 (1)和适配器(3; 3')彼此相对,所述保持器(1)设置有具有相互平行的凹槽的第一锯齿(12),并且适配器(3; 3')设置有第二 锯齿(16),具有相互平行的凹槽。 本发明还涉及支架(1)和适配器(3; 3')本身。 对于根据本发明的工具联接器来说重要的是,第一锯齿(12)位于具有基本上垂直于工具联接器的纵向中心轴线(13)的延伸的平面中,并且第二锯齿(16) 位于具有基本上垂直于所述纵向中心轴线(13)的延伸部的平面中。
