Embodiment 1
[0054] Such as Figure 1~9 A barrel reset pen shown includes a front rod 1, a rear pen holder assembly, a pen core 4, a return spring 41, an adjusting inner screw 47 and a reset movement. Both the above-mentioned return spring 41 and the pen core 4 are located in the body of the front rod 1, and the above-mentioned return spring 41 is specifically stuck between the pen core 4 and the front rod 1 . Above-mentioned back-moving spring 41, pen core 4 and reset movement are packed in the front bar 1 successively, and above-mentioned pen core 4 tail ends conflict with reset movement. The above-mentioned reset movement is engaged with the front rod 1, so that it is not easy to disengage from the front rod 1, thereby forming a positive pressure elastic reset pen. The positive pressure elastic reset pen has two forms, that is, the use state and the non-use state. The specific differences, form transformation process and form change principle are as follows:
[0055] The specific diff...
Embodiment 2
[0069] Such as Figure 1~4 And a kind of cylinder back reset pen shown in 10~15, comprises front rod 1, rear pen holder assembly, pen core 4, back-moving spring 41, adjusts internal rotation part 47 and resets movement. Both the above-mentioned return spring 41 and the pen core 4 are located in the body of the front rod 1, and the above-mentioned return spring 41 is specifically stuck between the pen core 4 and the front rod 1 . Above-mentioned back-moving spring 41, pen core 4 and reset movement are packed in the front bar 1 successively, and above-mentioned pen core 4 tail ends conflict with reset movement. The above-mentioned reset movement is engaged with the front rod 1, so that it is not easy to disengage from the front rod 1, thereby forming a positive pressure elastic reset pen. The above-mentioned positive pressure elastic reset pen has two forms, that is, an in-use state and a non-use state. The specific differences, form transformation process and form change princ...
Embodiment 3
[0083] Such as Figure 1~4 And a kind of cylinder back reset pen shown in 16~19, comprises front rod 1, rear pen holder assembly, pen core 4, back-moving spring 41, adjusts internal rotation part 47 and resets movement. Both the above-mentioned return spring 41 and the pen core 4 are located in the body of the front rod 1, and the above-mentioned return spring 41 is specifically stuck between the pen core 4 and the front rod 1 . Above-mentioned back-moving spring 41, pen core 4 and reset movement are packed in the front bar 1 successively, and above-mentioned pen core 4 tail ends conflict with reset movement. The above-mentioned reset movement is engaged with the front rod 1, so that it is not easy to disengage from the front rod 1, thereby forming a positive pressure elastic reset pen.
[0084] The above-mentioned positive pressure elastic reset pen has two forms, that is, an in-use state and a non-use state. The specific differences, form transformation process and form cha...
