    • A drill guide comprising a base, post fixed to the base, a carriage mounted on the post for movement toward and from the base, and an adjustable coupling on the carriage for securing a power drill thereto with the axis of the drill at a predetermined angle to the base, said carriage being adapted to be removed to enable using the drill independently of the base and to be restored without readjustment to said predetermined position. The coupling supports the drill forwardly and laterally of the post substantially centered with respect to the base and the base contains an opening through which the drill may be lowered into engagement with the work. There is means in the form of a second post for guiding the carriage as it is raised and lowered, a spring yieldably supporting the carriage above the base for movement toward the base, and means for limiting downward and upward movement of the carriage relative to the base. A gauge plate is adjustably mounted on the base below the opening and has on it intersecting gauge marks adapted to be aligned with the axis of the drill. A platen corresponding in configuration to the opening in the base is hingedly supported in the opening in which position its surface is flush with the surface of the base and for movement from the opening to a folded back position away from the opening.
    • 一种钻子引导器,其包括固定到基座的基部,柱体,安装在柱上以朝向和离开基部移动的滑架以及滑架上的可调节联接件,用于将钻头的轴线以预定角度固定在其上 所述托架适于被移除以能够独立于基座使用钻子并且在不重新调整到所述预定位置的情况下被恢复。 联接器支撑钻头的前部和侧面大体上相对于基座居中,并且基座包含开口,钻头可以通过该开口降低成与工件接合。 存在用于在升降时引导滑架的第二柱的形式的装置,弹簧可靠地支撑滑架在基座上方朝向底座移动,以及用于限制滑架相对于底座的向下和向上移动的装置 基础。 测量板可调节地安装在开口下方的基座上,并且在其上具有与钻头的轴线对准的相交的测量仪标记。 与基座中的开口相对应的压板被铰接地支撑在开口中,在该开口中,其表面与基部的表面齐平并且用于从开口移动到离开开口的折回位置。
