摘要： An earlobe piercer which has a pair of jaws that are movable towards and away from each other and a pressure plate mounted to one of the jaws which engages and holds the earlobe to be pierced. A slot in the pressure plate has a bottom end that supports one end of a piercing stud. The other end of the stud is disposed in an actuating mechanism which can be released to drive the stud linearly forward and through the earlobe while the stud is guided by the slot bottom. An enlarged cutout in the pressure plate provides visual access to the earlobe to be pierced to facilitate the alignment of any given point on the lobe with the stud. The piercer further provides means for positioning a stud-engaging clip which has an aperture that intercepts the travel path of the stud so that the stud engages the clip at the end of the piercing operation to thereby secure it to the earlobe.

摘要： An apparatus for piercing earlobes which comprises a pair of elongated, hand-held, parallel bars that can be moved towards and away from each other while an earlobe is positioned between the bars adjacent an end thereof. At that same end, one of the bars mounts an axially movable plunger to which an earlobe piercing stud can be attached. A compression spring drives the plunger and therewith the stud towards the second bar for piercing the ear. First and second levers are positioned for actuation by the same hand holding the piercing apparatus for retracting or cocking the plunger and for releasing it to pierce the earlobe. The second bar includes a recess into which a clip can be inserted which has an aperture for frictionally engaging the stud and retaining the stud to the earlobe after the latter has been pierced. The recess aligns the aperture with the axis of the plunger and a flat leaf spring is mounted to the second bar to bias the clip into the recess and retain it therein in its properly aligned position. The extent to which the two bars can be moved towards each other is adjustable.

摘要翻译： 一种用于刺穿耳垂的装置，其包括一对细长的手持式平行条，其可以在耳垂定位在邻近其端部的条之间而彼此移动并远离彼此。 在同一端，其中一个杆安装可轴向移动的柱塞，耳垂穿孔螺柱可以连接到该柱塞上。 压缩弹簧将柱塞驱动柱塞并使其与第二杆一起驱动以刺穿耳朵。 第一和第二杠杆被定位成由同一只手握住穿刺装置的手来致动，用于使柱塞缩回或起动并将其释放以刺穿耳垂。 第二杆包括凹部，夹子可插入该凹槽中，该凹槽具有用于摩擦接合螺柱的孔，并且在螺栓被刺穿之后将柱保持在耳垂上。 凹部将孔与柱塞的轴线对准，并且平板簧安装到第二杆以将夹子偏置到凹部中并将其保持在其适当对准的位置。 两个条可以彼此移动的程度是可调节的。
