Wherein the connecting section 31           The connection mode with the ink tank 1 is screwed to facilitate the disassembly and assembly of the entire pencil;           The radial dimension of the inner wall of the segment 32 is greater than the radial dimension of the shaft 22 and smaller than the head 21           Radial dimension, and smaller than the radial dimension of the rod segment of the push rod 2 having the ribs 221, the limit           The inner wall of the segment 32 is provided with a groove 321 adapted to the rib 221 in the axial direction of the locking cover 3, the limit           The segment 32 is located at a distance between the rib 221 and the head 21, so that the locking can be ensured           a cover 3 connecting the ink tank 1 and the push rod 2 into one body, and ensuring that the push rod 2 is opposite to the           The reservoir 1 is twisted in the radial direction.                 
下面介绍本发明的工作原理：本发明提供的吸注两用笔胆，可通过径向 扭转所述推杆2的方式来调整所述推杆2上的凸条221与所述锁紧盖3上的 凹槽321的对位情况，进而切换整个笔胆添加墨水的方式。当所述凸条221 与所述凹槽321相互对齐时，所述推杆2可以沿其轴向往复运动，从而实现 传统的吸墨式添加墨水的过程；当所述凸条221与所述凹槽321相互错位时， 所述凸条221抵顶所述限位段32，从而实现所述推杆2在轴向上的定位，此 时采用专用的墨水瓶，将墨水瓶上的出墨针穿过所述容纳腔内的橡胶密封件 5并进入所述中心通孔201，使墨水流经所述中心通孔201向所述贮墨胆1 内添加墨水。由此可见本发明提供的笔胆同时具备吸墨与灌墨的功能，且操 作简便，适用性强。 The working principle of the present invention is described below: the suction-and-smoke pen provided by the present invention can pass through the radial direction.           Reversing the push rod 2 to adjust the ribs 221 on the push rod 2 and the locking cover 3           The alignment of the grooves 321 further switches the manner in which the entire pen is filled with ink. When the rib 221           When the grooves 321 are aligned with each other, the push rod 2 can reciprocate along its axial direction, thereby realizing           a conventional ink absorbing process of adding ink; when the rib 221 and the groove 321 are displaced from each other,           The rib 221 abuts the limiting segment 32 to achieve positioning of the push rod 2 in the axial direction.           A special ink bottle is used to pass the ink discharge needle on the ink bottle through the rubber seal in the receiving chamber                               5 and entering the central through hole 201, so that ink flows through the central through hole 201 to the ink reservoir 1           Add ink inside. It can be seen that the pen provided by the invention has the functions of ink absorption and ink filling, and           Easy to use and adaptable.                 
在本实施例中，所述头部21上设有环形卡槽，所述柔性橡胶圈4套设 于所述环形卡槽内，这样可使所述柔性橡胶圈4不易从所述头部21上脱落。 进一步，所述头部顶端为锥形，这样可以方便所述柔性橡胶圈4的安装。 In this embodiment, the head 21 is provided with an annular card slot, and the flexible rubber ring 4 is sleeved.           In the annular card slot, the flexible rubber ring 4 is not easily detached from the head portion 21.           Further, the top end of the head is tapered, which facilitates the installation of the flexible rubber ring 4.                 
在本实施例中，所述限位段32的端面于设置所述凹槽321处设有卡位 缺口322。如此，若对本发明的笔胆进行灌墨时，可使所述凸条221与所述 凹槽321错位且抵顶所述卡位缺口322，使所述凸条221仅可在所述卡位缺 口322内滑动，用以限制所述凸条221的扭转角度，从而降低使所述凸条221 从与所述凹槽321由相互错位到相互对齐的操作难度。 In this embodiment, the end surface of the limiting segment 32 is provided with a card position at the groove 321           Notch 322. Thus, when the ink of the present invention is inked, the ribs 221 and the           The groove 321 is misaligned and abuts against the card notch 322, so that the rib 221 can only be missing at the card position.           Sliding in the mouth 322 to limit the twist angle of the rib 221, thereby reducing the rib 221           The operational difficulty from being misaligned with the grooves 321 to be aligned with each other.                 
在本实施例中，所述锁紧盖31上与所述贮墨胆1螺纹连接，这样，可 以便于所述锁紧盖31的拆装。 In the embodiment, the locking cover 31 is screwed to the ink tank 1 so that           In order to facilitate the disassembly and assembly of the locking cover 31.                 
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本 发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本 发明的保护范围之内。 The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention.           Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the invention shall be included in this           Within the scope of protection of the invention.
