    • A double-chuck mechanical pencil comprises: a barrel (1); a barrel cap (2) attached to the barrel; a lead tank (4) axially slidably inserted in the barrel; a back chuck (5) fixedly joined to the front end of the lead tank; a chuck ring (6) loosely fitted on the chucking head (5a) of the back chuck; a tubular member (7) disposed so as to surround the front portion of the lead tank; a back elastic member (8) placed in the tubular member so as to bias the lead tank backward; a coupling member (9) combined with the tubular member, and provided in its inner circumference with stopping portions with which the tubular member and the chuck ring come into contact, respectively; a front chuck (12) fixedly joined to the front portion of the coupling member; and a front elastic member (11) interposed between the barrel cap and the coupling member so as to bias the coupling member backward. A rotation prohibiting means (28) permits the axial movement of the coupling member and prohibits the rotation of the same relative to the tubular member. A tail cap (25) is attached to the back end of the barrel and a push cap (27) is put detachably on the back end of the lead tank. Another rotation prohibiting means permits the axial movement of the push cap and prohibits the rotation of the same relative to the tail cap.
    • 双卡盘自动铅笔包括:桶(1); 连接到桶的桶盖(2); 可滑动地插入筒体中的铅罐(4) 固定地连接到铅罐的前端的后卡盘(5); 松紧地装配在后夹盘的夹头上的卡盘环(6) 管状构件(7),设置成围绕铅罐的前部; 背部弹性构件(8),其放置在所述管状构件中,以将所述铅槽向后偏置; 与所述管状构件组合的联接构件(9),并且在其内周设置有分别与所述管状构件和所述卡盘环接触的止动部分; 固定地连接到所述联接构件的前部的前卡盘(12); 以及插入在所述筒盖和所述联接构件之间以便向后偏压所述联接构件的前弹性构件(11)。 旋转禁止装置(28)允许联接构件的轴向运动并且禁止其相对于管状构件的旋转。 一个尾盖(25)安装在枪管的后端,并且一个推盖(27)可拆卸地装在铅罐的后端上。 另一个旋转禁止装置允许推盖的轴向移动并且禁止其相对于尾盖的旋转。

    • A rotary pencil includes a sleeve-shaped shaft having a front end and a rear end, a threaded spindle mounted to be fixed against rotation and axially movable in said shaft and having an at least single-start external thread. At least one threaded element is fixed in axial and rotating directions relative to the shaft and engages into the external thread. The front end of the external thread is adjoined by a cylindrical spindle section which extends over the entire circumference of the spindle, namely a free-running section, and has an external diameter corresponding to a core diameter of the external thread.
    • 一种旋转式铅笔包括具有前端和后端的套筒形轴,螺纹主轴安装成固定以防止旋转并且可在所述轴中轴向移动并且具有至少一个起始的外螺纹。 至少一个螺纹元件相对于轴固定在轴向和旋转方向上并且接合到外螺纹中。 外螺纹的前端由圆柱形主轴部分相邻,圆柱形主轴部分在主轴的整个圆周上延伸,即自由运动部分,并且具有对应于外螺纹的芯直径的外径。
