摘要： A mechanical pencil has an axially elongated hollow pencil body in which is slidable a tubular seat member. A lead-protecting sleeve is axially displaceable in the pencil body between a front position and a rear position and is urged into the front position with a relatively strong spring force. At least two jaws are axially displaceable on the seat and are moved radially closer as they move backwardly from the tip so as to grip a lead that projects backwardly from the lead-projecting sleeve. A relatively weak spring urges these jaws backwardly in the seat. An O-ring is provided in the lead-projecting sleeve so that each time the pencil tip is lifted from the writing surface the lead is automatically pulled forwardly by the strong spring force through the jaws. Similarly forward displacement of the seat in which the jaws rest allows for manual advance of a lead gripped by the jaws and passing through the lead-protecting sleeve.

摘要翻译： 一种自动铅笔具有轴向细长的中空铅笔体，其中可滑动的管状座椅构件。 引线保护套筒可以在铅笔本体中在前位置和后位置之间轴向移动，并以相对较强的弹簧力推动到前部位置。 至少两个钳口在座椅上可轴向移动，并且当它们从尖端向后移动时，其径向更靠近地移动，以便夹持从引导突出套筒向后突出的引线。 相对较弱的弹簧将这些颚向后推到座位上。 在引导突出套筒中设置有O形环，使得每当笔尖从书写表面抬起时，引线将被强力弹簧力自动地向前拉过钳口。 类似地，其中夹持件的座椅的向前位移允许手动前进由钳口夹持并穿过引线保护套筒的引线。

摘要： A device for receiving a writing implement has a housing, a resiliently yieldable sealing member in the housing and adapted to sealingly abut against a writing tubular member of the writing implement, and a wetting member in the housing and located in spaced relationship with a pressure-equalizing passage of the writing implement as well as communicating with the passage. The resiliently yieldable member may be composed of two axially movable balls which are received in a cylindrical portion of the housing and axially limited by two axially spaced collars. The cylindrical portion may be connected with a conical extension which, in turn, may be connected with a further cylindrical portion received in the receiving opening of the housing. These portions may be of one-piece with each other so as to form a one-piece insert member.

摘要翻译： 一种用于接收书写工具的装置，具有壳体，该壳体中的可弹性收缩的密封构件，并适于密封地抵靠书写工具的书写管状构件，以及位于壳体中的润湿构件， 平衡书写工具的通过以及与通道的通信。 弹性屈服构件可以由两个可轴向移动的球组成，其被容纳在壳体的圆柱形部分中并且轴向地由两个轴向间隔开的轴环限制。 圆柱形部分可以与圆锥形延伸部连接，圆锥形延伸部又可以与容纳在壳体的接收开口中的另外的圆柱形部分连接。 这些部分可以彼此成一体，以便形成一体的插入部件。
