具体实施方式
下面结合附图对本发明做进一步描述。
实施例1：
如图1至7所示的一种自锁旋转提拉笔，包括第一杆体1、第二杆筒2、笔芯3和复位弹簧4，上述笔芯3和复位弹簧4皆套接于第一杆体1内，上述第一杆体1和笔芯3套接于第二杆筒2内。上述第一杆体1由握笔部11和套接部12组成，上述套接部12上设有一个及其以上异型组合槽13，上述异型组合槽13由安装切入槽131、十字槽132和配合槽133依次排列组成。上述异型组合槽13内还设有延伸内杆14，上述延伸内杆14自安装切入槽131起，一直延伸到配合槽133内，上述延伸内杆14上设有安装凸起141和异型凸块142。上述安装凸起141具体位于安装切入槽131和十字槽132之间，上述异型凸块142具体位于配合槽133内。上述配合槽133被异型凸块142分割成配合切换区135、配合进入区136、配合回落区134和回落复位坡137。上述第二杆筒2内设有可移动于异型组合槽13的配合倒钩21。上述异型凸块142其表面还设有辅助坡道1421，靠配合切换区135端还设有配合凹槽1422。上述配合倒钩21在异型组合槽13内的位置关系，决定两种配合状态，具体配合状态如下：
一、使用状态，此时配合倒钩21位于异型凸块142内，具体位于配合凹槽1422内，此时，笔芯的笔尖部分处于部分露出第一杆体1的状态。
二、携带状态，此时配合倒钩21位于十字槽132内，此时，笔芯完全隐藏于第一杆体1和第二杆筒2内。
为了实现笔芯的露出和隐藏，主要通过配合倒钩在异型组合槽内的移动，产生的两个具有稳定性的静态位置，分别实现了笔芯露出时，第一杆体和第二杆筒的配合状态。笔芯隐藏时的配合状态，而两个状态之间的切换，则为配合倒钩21在异型组合槽13的活动轨迹。上述配合倒钩21在异型组合槽13的活动轨迹具体如下：
一、自安装切入槽131，通过安装凸起141，进入十字槽132。
二、自十字槽132进入配合槽133。
三、在配合槽133内，通过配合进入区136使其与异型凸块142发生接触，通过辅助坡道1421使得异型凸块142往轴心偏移，即延伸内杆14发生形变，随后进入配合切换区，进入配合切换区后，延伸内杆14其形变复位，即异型凸块142结构复位，使得配合倒钩21被固定于配合凹槽1422内。
四、随后可通过旋转第二杆筒2使得配合倒钩21往左或右移动，使其脱离配合凹槽 1422，进入配合回落区134。
五、进入配合回落区134后，会受到复位弹簧4的弹力作用，使其配合倒钩21自动往回落复位坡137处移动。
六、而回落复位坡137则会引导配合倒钩21脱离配合槽133的范围，重新进入十字槽132内。
七、若无需更换笔芯，则重复第二到第六步骤即可。
八、若需要更换笔芯，则完成第六步骤后，通过安装凸起141自十字槽132移动到安装切入槽131，随后离开异型组合槽13即可。
为了使得使用状态切换到携带状态的快速和省力。上述配合凹槽1422的两侧设有导出辅坡1423，其开口往外，帮助配合倒钩21从配合凹槽1422两侧离开配合凹槽1422。
为了避免配合倒钩21初入配合槽时，进入除配合进入区以外的其他部分，从而影响其完成上述步骤3的操作，影响进入使用状态。上述异型凸块142其靠配合进入区136端，还设有导向进入坡1424。上述导向进入坡1424其开口朝外，帮助配合倒钩21自配合进入区136进入辅助坡道1421。其导向进入坡1424可以很好的防止配合倒钩的移动轨迹发生偏移。
为了使得延伸内杆具有良好的弹性和形变能力，确保异型凸块和安装凸起的具有一定的弹性，方便其和配合倒钩进行后续的配合。而安装凸起只是在安装和更换笔芯时需要用到，故此，其配合倒钩和安装凸起的卡合力度，应该大于配合倒钩和异型凸块的卡合力度，这样可以在确保配合倒钩和异型凸块的配合状态稳定的前提下，确保配合倒钩不易通过安装凸起，避免发生配合倒钩意外脱离异型组合槽的情况。上述延伸内杆14与十字槽132和配合槽133之间设有间隙，其并不产生接触，故此，异型凸块142也不和配合槽133产生接触。上述延伸内杆14与安装切入槽131两边也设有间隙，但是延伸内杆14其底边与安装切入槽131相连，故此，安装凸起141也不和十字槽132或安装切入槽131产生接触。但，由于延伸内杆14其底边是与安装切入槽131相连。而安装凸起141相较于异型凸块142，其离延伸内杆14的底边较近。故此，其受到同等外力产生形变的幅度，小于异型凸块142受到外力压迫，从而导致延伸内杆14产生的形变幅度。即，配合倒钩通过安装凸起14的所需力度，大于配合倒钩通过异型凸块142的所需力度。
为了使得配合倒钩只能滑入异型凸块的配合凹槽，却无法原路离开配合凹槽，只能通过侧移的方式，离开配合凹槽。使其能够在配合倒钩进入配合凹槽后，确保第一杆体和第二筒体的结构配合稳定性，方便书写人，书写着力。上述配合倒钩21其结构为朝内弯曲的倒钩状结构，便于其勾住配合凹槽1422，使其极易横向进入配合凹槽1422但却无法横向脱离配合凹槽1422。但，不影响其通过配合凹槽1422左右两侧，滑出配合凹槽1422。
作为本发明的进一步优选：上述第一杆体1的握笔部11上可套接设有握笔套。上述第二杆筒2上可套接设有虎口套。上述握笔套和虎口套皆为软胶套。
实施例2：
如图8至15所示的一种自锁旋转提拉笔，包括第一杆体1、第二杆筒2、笔芯3和复位弹簧4，上述笔芯3和复位弹簧4皆套接于第一杆体1内，上述第一杆体1和笔芯3套接于第二杆筒2内。上述第二杆筒2由千叶件22和杆筒体21组成，上述千叶件22上延伸设有2个及其以上的延伸千叶杆221，上述千叶件22和杆筒体21卡合连接，上述杆筒体21可相对千叶件22旋转。上述第一杆体1由握笔部11和套接部12组成。上述握笔部11上设有与延伸千叶杆221数量一 致的千叶槽111。上述延伸千叶杆221滑动安装于千叶槽111内。上述套接部12上设有一个及其以上异型组合槽13，上述异型组合槽13由安装切入槽131、十字槽132和配合槽133依次排列组成。上述异型组合槽13内还设有延伸内杆14，上述延伸内杆14自安装切入槽131起，一直延伸到配合槽133内，上述延伸内杆14上设有安装凸起141和异型凸块142。上述安装凸起141具体位于安装切入槽131和十字槽132之间，上述异型凸块142具体位于配合槽133内。上述配合槽133被异型凸块142分割成配合切换区135、配合进入区136、配合回落区134和回落复位坡137。上述杆筒体21内设有可移动于异型组合槽13的配合倒钩21。上述异型凸块142其表面还设有辅助坡道1421，靠配合切换区135端还设有配合凹槽1422。
上述配合倒钩21在异型组合槽13内的位置关系，决定两种配合状态，具体配合状态如下：
一、使用状态，此时配合倒钩21位于异型凸块142内，具体位于配合凹槽1422内，此时，笔芯的笔尖部分处于部分露出第一杆体1的状态。
二、携带状态，此时配合倒钩21位于十字槽132内，此时，笔芯完全隐藏于第一杆体1和第二杆筒2内。
为了实现锁定第一杆体和第二杆筒上下移动的功能，使其在外出携带时，避免笔芯受到外力影响而露出。上述十字槽132的两侧还分别设有自锁槽1322。上述自锁槽1322和十字槽132之间还分别设有辅助进坡1323和自锁辅坡1321。上述自锁槽1322与辅助进坡1323和自锁辅坡1321之间还设有防脱凸起13221。上述配合倒钩21可通过辅助进坡1323和自锁辅坡1321，在克服防脱凸起13221的阻力后，进出自锁槽1322。使其具有第三种配合状态，即：自锁状态，此时配合倒钩21位于自锁槽1322内，笔芯完全隐藏于第一杆体1和第二杆筒2内，且第一杆体1和第二杆筒2的上下移动关系被锁定，第一杆体1无法和第二杆筒2发生上下移动。
为了实现笔芯的露出和隐藏，主要通过配合倒钩在异型组合槽内的移动，产生的三个具有稳定性的静态位置，分别实现了笔芯露出时，第一杆体和第二杆筒的配合状态。笔芯隐藏时的配合状态。笔芯隐藏，同时锁定了第一杆体和第二杆筒上下移动功能时，第一杆体和第二杆筒的配合状态。而这三个状态之间的切换，则为配合倒钩21在异型组合槽13的活动轨迹。上述配合倒钩21在异型组合槽13的活动轨迹如下：
一、自安装切入槽131，通过安装凸起141，进入十字槽132。
二、自十字槽132进入配合槽133。
三、在配合槽133内，通过配合进入区136使其与异型凸块142发生接触，通过辅助坡道1421使得异型凸块142往轴心偏移，即延伸内杆14发生形变，随后进入配合切换区，进入配合切换区后，延伸内杆14其形变复位，即异型凸块142结构复位，使得配合倒钩21被固定于配合凹槽1422内。
四、随后可通过旋转第二杆筒2使得配合倒钩21往左或右移动，使其脱离配合凹槽1422，进入配合回落区134。
五、进入配合回落区134后，会受到复位弹簧4的弹力作用，使其配合倒钩21自动往回落复位坡137处移动。
六、而回落复位坡137则会引导配合倒钩21脱离配合槽133的范围，重新进入十字槽132内。
七、若无需更换笔芯，则重复第二到第六步骤即可。
八、若需要更换笔芯，则完成第六步骤后，通过安装凸起141自十字槽132移动到安装切入槽131，随后离开异型组合槽13即可。
九、若需结构自锁，则完成第六步骤后，通过旋转第二杆筒2，使得配合倒钩21往左或右移动，使其克服防脱凸起13221的阻力后，进入自锁槽1322。
十、若想解除自锁状态，则完成第九步骤后，通过旋转第二杆筒2，使得配合倒钩21往左或右移动，使其克服防脱凸起13221的阻力后，重新进入十字槽132内。
为了使得使用状态切换到携带状态的快速和省力。上述配合凹槽1422的两侧设有导出辅坡1423，其开口往外，帮助配合倒钩21从配合凹槽1422两侧离开配合凹槽1422。
为了避免配合倒钩21初入配合槽时，进入除配合进入区以外的其他部分，从而影响其完成上述步骤3的操作，影响进入使用状态。上述异型凸块142其靠配合进入区136端，还设有导向进入坡1424。上述导向进入坡1424其开口朝外，帮助配合倒钩21自配合进入区136进入辅助坡道1421。其导向进入坡1424可以很好的防止配合倒钩的移动轨迹发生偏移。
为了使得延伸内杆具有良好的弹性和形变能力，确保异型凸块和安装凸起的具有一定的弹性，方便其和配合倒钩进行后续的配合。而安装凸起只是在安装和更换笔芯时需要用到，故此，其配合倒钩和安装凸起的卡合力度，应该大于配合倒钩和异型凸块的卡合力度，这样可以在确保配合倒钩和异型凸块的配合状态稳定的前提下，确保配合倒钩不易通过安装凸起，避免发生配合倒钩意外脱离异型组合槽的情况。上述延伸内杆14与十字槽132和配合槽133之间设有间隙，其并不产生接触，故此，异型凸块142也不和配合槽133产生接触。上述延伸内杆14与安装切入槽131两边也设有间隙，但是延伸内杆14其底边与安装切入槽131相连，故此，安装凸起141也不和十字槽132或安装切入槽131产生接触。但，由于延伸内杆14其底边是与安装切入槽131相连。而安装凸起141相较于异型凸块142，其离延伸内杆14的底边较近。故此，其受到同等外力产生形变的幅度，小于异型凸块142受到外力压迫，从而导致延伸内杆14产生的形变幅度。即，配合倒钩通过安装凸起14的所需力度，大于配合倒钩通过异型凸块142的所需力度。
为了使得配合倒钩只能滑入异型凸块的配合凹槽，却无法原路离开配合凹槽，只能通过侧移的方式，离开配合凹槽。使其能够在配合倒钩进入配合凹槽后，确保第一杆体和第二筒体的结构配合稳定性，方便书写人，书写着力。上述配合倒钩21其结构为朝内弯曲的倒钩状结构，便于其勾住配合凹槽1422，使其极易横向进入配合凹槽1422但却无法横向脱离配合凹槽1422。但，不影响其通过配合凹槽1422左右两侧，滑出配合凹槽1422。
作为本发明的进一步优选：上述第一杆体1的握笔部11上可套接设有握笔套。上述第二杆筒2上可套接设有虎口套。上述握笔套和虎口套皆为软胶套。

    九、若需结构自锁，则完成第六步骤后，通过旋转第二杆筒(2),使得配合倒钩(21)往左或右移动，使其克服防脱凸起(13221)的阻力后，进入自锁槽(1322)；
    十、若想解除自锁状态，则完成第九步骤后，通过旋转第二杆筒(2),使得配合倒钩(21)往左或右移动，使其克服防脱凸起(13221)的阻力后，重新进入十字槽(132)内。
  6. 根据权利要求1～5所述的一种自锁旋转提拉笔，其特征在于：所述配合凹槽(1422)的两侧设有导出辅坡(1423),其开口往外，帮助配合倒钩(21)从配合凹槽(1422)两侧离开配合凹槽(1422)。
  7. 根据权利要求6所述的一种自锁旋转提拉笔，其特征在于：所述异型凸块(142)其靠配合进入区(136)端，还设有导向进入坡(1424)；所述导向进入坡(1424)其开口朝外，帮助配合倒钩(21)自配合进入区(136)进入辅助坡道(1421)。
  8. 根据权利要求7所述的一种自锁旋转提拉笔，其特征在于：所述延伸内杆(14)与十字槽(132)和配合槽(133)之间设有间隙，其并不产生接触，故此，异型凸块(142)也不和配合槽(133)产生接触；所述延伸内杆(14)与安装切入槽(131)两边也设有间隙，但是延伸内杆(14)其底边与安装切入槽(131)相连，故此，安装凸起(141)也不和十字槽(132)或安装切入槽(131)产生接触；但，由于延伸内杆(14)其底边是与安装切入槽(131)相连；而安装凸起(141)相较于异型凸块(142),其离延伸内杆(14)的底边较近；故此，其受到同等外力产生形变的幅度，小于异型凸块(142)受到外力压迫，从而导致延伸内杆(14)产生的形变幅度；即，配合倒钩通过安装凸起(14)的所需力度，大于配合倒钩通过异型凸块(142)的所需力度。
  9. 根据权利要求8所述的一种自锁旋转提拉笔，其特征在于：所述配合倒钩(21)其结构为朝内弯曲的倒钩状结构，便于其勾住配合凹槽(1422),使其极易横向进入配合凹槽(1422)但却无法横向脱离配合凹槽(1422)；但，不影响其通过配合凹槽(1422)左右两侧，滑出配合凹槽(1422)。
  10. 根据权利要求1～9任一所述的一种自锁旋转提拉笔，其特征在于：所述第一杆体(1)的握笔部(11)上可套接设有握笔套；所述第二杆筒(2)上可套接设有虎口套；所述握笔套和虎口套皆为软胶套。
