    • A hand tool (1) having a drive motor (12), a depth stop (16) by which the drive motor (12) can be automatically switched off when it is in contact with a workpiece (4), and a switching mechanism (21) in an electric circuit (22). The electric circuit (22) includes a switch (24) for switching the drive motor (12) on and off, a first contact element (25) for reversing the polarity of the drive motor (12) and a second contact element (26) for switching off the drive motor (12) by the use of the depth stop (16). Also, a switching device (32) is connected to the drive motor (12) and is integrated into the electric circuit (22) so that the switching device (32) is arranged in a branch line (31) bypassing the second contact element (26) and by which the second contact element (26) can be bypassed in an open operating position caused by the depth stop (16) by actuation of the first contact element (25) for reversal of the direction of rotation of the drive motor (12), which makes it possible to switch the drive motor (12) from clockwise to counter-clockwise rotation or the reverse without the necessity of mechanical elements and without the necessity of any manual manipulation of adjustment elements.

    • In a device (1) for stirring and for dosing the mixing ratio of different kinds of liquid (2), in particular of paints (3) and a thinning agent (4), consisting of a stirring rod (6) and a reservoir container (5) in which the liquids to be mixed together are filled, it should be possible to measure the amount of liquid (2) to be added in relation to the amount of fluid (2) already contained, and to do so in a quick and easy manner using the stirring rod (6).This is achieved in that the stirring rod (6) has got at least two measuring openings (11) worked into it, which are spaced apart in the direction of the lengthways axis (7) of the stirring rod (6), and that the dimension of the particular measuring opening (11) measured parallel to the lengthways axis (7), and the measuring web (12) remaining between two adjacent measuring openings (11), are configured in relation to the fill level of the liquids (2) that are put into the reservoir container (5), or at least one jacket surface of the stirring rod (6) has got one or more measuring bodies (13) formed on it, which are spaced at intervals from one another in the direction of the lengthways axis (7) of the stirring rod (6) and in relation to the fill level in the reservoir container (5), and that the dimension of the measuring bodies (13) running in the direction of the lengthways axis (7) of the stirring rod (6) is configured in relation to the fill level in the reservoir container (5).
    • 在用于搅拌和给料不同种类的液体(2),特别是油漆(3)和稀释剂(4)的混合比例的装置(1)中,搅拌棒(6)和储存容器 (5)其中要混合的液体被填充,应该可以测量相对于已经包含的流体(2)的量添加的液体(2)的量,并且以快速 并且容易地使用搅拌棒(6)。 这是因为搅拌棒(6)具有至少两个在其中加工的测量开口(11),它们沿搅拌棒(6)的纵向轴线(7)的方向间隔开,并且 与两个相邻的测量开口(11)之间平行的纵向轴线(7)测量的特定测量开口(11)的尺寸和剩余的测量卷筒纸(12)相对于液体(2)的填充水平构成, 放入储存容器(5)中,或者搅拌棒(6)的至少一个护套表面具有形成在其上的一个或多个测量体(13),它们彼此间隔开。 搅拌棒(6)的纵向轴线(7)和相对于储存容器(5)中的填充液面的尺寸,以及沿纵向轴线(7)的方向延伸的测量体(13)的尺寸, 搅拌棒(6)相对于储存容器(5)中的填充水平构造。
