    • A percussive tool has a working tool mounted for reciprocations in a barrel. A collar is arranged between a shank and a working portion of the working tool. The shank of the working tool reciprocates in a guide bushing secured in the barrel to ensure reciprocations of the working tool. There is provide4d a member for determining the angular position of the working tool during the reciprications, the member comprising either the barrel proper in case of concrete breakers, or a hood, e.g. in chipping hammers. For positively controlling the angular position of the working tool, there is provided a spring having two portions of different cross-sectional configuration, a first portion being coupled for a combined rotation to the member determining the angular position of trhe working tool, and a second portion being of a cross-sectional configuration corresponding to the cross-sectional configuration of the working portion of the working tool.
    • 冲击工具有一个工作工具,安装在桶中往复运动。 套环位于工具的柄和工作部分之间。 加工工具的刀柄在固定在枪管中的引导衬套中往复运动,以确保工作工具的往复运动。 提供了一个用于确定加工工具在收割期间的角位置的构件,该构件包括在混凝土破碎机的情况下的桶本体,或罩,例如罩。 在碎石锤。 为了积极地控制加工工具的角度位置,提供了一种具有不同横截面构造的两个部分的弹簧,第一部分被联接成用于组合的旋转,以确定工作工具的角位置,并且第二部分 部分是与工作工具的工作部分的横截面形状对应的横截面构造。

    • The device for drilling holes in the ground comprises a body (1), a drive and a base member (3), connected with the body by means of a thread (4) and provided a with a lug (7) located on an external side surface (6). The lug (7) is intended for locking the base member (3) relative to the body (1) and is projected beyond the latter. One of the sides (10) is inclined to the generatrix of the side surface (6) of the base member (3) in the direction creating a turning-in moment at the connecting thread. Located on the base member side surface is an additional lug (12) which creates a turning-in moment at the connecting thread in case the device is reversed.
