Embodiment Construction

[0010] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a pen holder 1 and a pen container 2 arranged outside the pen holder 1. A spacer 3 is arranged at the rear top of the pen case 2. The spacer 3 is movable in the pen case 2. The spacer 3 is connected to the top of the pen case 2 by a spring 4. , The gasket 3 is inlaid with a pyramid-shaped rubber stopper 5, and the pyramid-shaped rubber stopper 5 is inlaid on the gasket 3 upside down.

[0011] With the anti-missing carbon pen of the present invention, when the pyramidal rubber stopper 5 squeezes the top end of the penholder 1, after a part of the pyramidal rubber stopper 5 enters the top end of the penholder 1, the gas volume in the penholder 1 decreases due to extrusion. , the pressure becomes larger, the ink will not be missed, even if the ink rushes out of the liquid that blocks its movement, it will not overflow the pen holder 1, and because the length of differen...
