The specific embodiment:

Embodiment 1: extremely shown in Figure 5 as Fig. 1, damping pen cap 2 is positioned at a shell 1 front end, this damping pen cap 2 has back-moving spring 3, the rear end that rotation control lever 4 is arranged in the shell 1 and its head exposes a shell 1, one end of pen core 6 is connected with damping pen cap 2, the other end then connects pen core actuator 5, and the bar portion monodisplacement of this pen core actuator 5 and rotation control lever 4 cooperates, and constitutes pen core monodisplacement mechanism.The monodisplacement fit form of pen core actuator 5 and rotation control lever 4 can have multiple, the rotation control lever 4 of present embodiment is provided with unidirectional tooth bar 7, the top of pen core actuator 5 is provided with elastic fin 8, and the free end of elastic fin 8 and unidirectional tooth bar 7 match, and constitutes pen core monodisplacement mechanism.

In the use, after the pen core 6 that exposes damping pen cap 2 had been write, the front end of damping pen cap 2 touched paper naturally, and damping pen cap 2 moves back some distances in shrinking under writing pressure, and pen core 6 was also withstood by pen core actuator 5 and kept fixing this moment.When damping pen cap 2 is mentioned when leaving paper slightly, back-moving spring 3 is with damping pen cap 2 elastic recoverys, can be pulled outwardly pen core 6 by damping action this moment, pen core actuator 5 also is pulled, because moving along unidirectional tooth bar 7, lifts the free end of elastic fin 8, can not block tooth portion, pen core 6 can be pulled out one section and expose damping pen cap 2 and describe for writing automatically like this.Touching paper in the front end writing process of pen core 6 also is under pressure, but pen core actuator 5 is when pushing inward trend, and the free end of elastic fin 8 is pressed down against unidirectional tooth bar 7, the radical length expansion, firmly block unidirectional tooth bar 7, pen core actuator 5 can't move together with pen core 6 like this.

During use, rotation control lever 4 can rotate the cooperation that contacts of the unidirectional tooth bar 7 of control and elastic fin 8.Be used when too short in pen core 6 length, when namely pen core actuator 5 also moves on to unidirectional tooth bar 7 ends, can rotate the cooperation that breaks away from unidirectional tooth bar 7 and elastic fin 8, pen core 6 can be taken out fully and changes like this.

The top of the pen core actuator 5 of present embodiment is provided with two elastic fins 8, generally as shown in Figure 4, is staggeredly arranged in opposite directions, certainly also can be as shown in Figure 6, and two elastic fins 8 distribute for V-type.Unidirectional tooth bar 7 on the rotation control lever 4 also has two, and with two elastic fin 8 corresponding matching, screens is more reliable so respectively.Below elastic fin 8 is free-ended, on the top of pen core actuator 5, also can be provided with smooth filler strip 9, constitute the flaps down supporting construction, can prevent 8 times compressive strains of elastic fin like this, support more firm.In fact, the sidewall of pen core actuator 5 also is provided with pin 10, can prevent from rotating.
