    • A drill (100) for drilling a material (104) with a drill bit (102) which is specially adapted for use by inexperienced users is provided. The drill (100) includes a rotatable helix screw (132) having a helix groove (134). A support block (136) travels up and down the helix screw (132) when the helix screw (132) is rotated via a handle section (120). A key pin (138) is mounted in the support block (136) to ride in the helix groove (134). Preferably, the center of mass of the support block (136) is tangential to the helix screw (132). A short level section (304) is formed in the bottom of the helix groove (134) such that the key pin (138) rests in the level section (304) when not in use. The drill (100) may comprise an overhead support mechanism (108) for rotatably supporting the drill (100).
    • 提供了一种用于钻出具有特别适合无经验用户使用的钻头(102)的材料(104)的钻(100)。 钻头(100)包括具有螺旋槽(134)的可旋转螺旋螺钉(132)。 当螺旋螺钉(132)经由手柄部分(120)旋转时,支撑块(136)在螺旋螺钉(132)上上下移动。 钥匙销(138)安装在支撑块(136)中以骑在螺旋槽(134)中。 优选地,支撑块(136)的质心与螺旋螺钉(132)相切。 在螺旋槽(134)的底部形成有短的水平部(304),使得当不使用时,键销(138)搁置在水平部(304)中。 钻头(100)可以包括用于可旋转地支撑钻头(100)的顶部支撑机构(108)。
