    • Mounting device for connecting a drill bit (4) to a hand drill (1), to allow drilling through one of two adjoining surfaces parallel to and with insignificant spacing from the negligible other of said surfaces, the device comprising a rigid arm (6) which at one of its ends is provided with means (7) for attachment to the said hand drill (1) and at its other end provides a journal (8) for a holder (9) intended to carry the drill bit (4). The journalled holder (9) is connected to the hand drill (1) through torque and impact transmitting means comprising rigid rods (10) and universal joints means (11). The journalled holder (9) is offset relative to the hand drill (1) and the drill bit (4) is attached to the journalled holder (9) through a radially restricted connection means so as to allow the drilling close to and parallel to such a surface.
    • 用于将钻头(4)连接到手钻(1)的安装装置,以允许钻穿与两个相邻的表面平行并且与所述可忽略的其他所述表面间隔不大的两个邻接表面之一,所述装置包括刚性臂(6) 在其一个端部处设置有用于附接到所述手钻(1)的装置(7),并且在其另一端处提供用于承载钻头(4)的保持器(9)的轴颈(8)。 轴承座(9)通过包括刚性杆(10)和万向节装置(11)的扭矩和冲击传递装置连接到手钻(1)。 轴颈支架(9)相对于手钻(1)偏移,并且钻头(4)通过径向限制的连接装置附接到轴颈支架(9),以允许钻孔靠近并平行于该钻头 一个表面。
