该外定位装置40，设于该外伸缩座20之中，且可由该外横管21处控制其嵌入或脱离该两管座10的多个外定位孔13的其中一者，以达到将该两外伸缩管22定位于适当伸缩长度的目的。
该内定位装置50，设于该内伸缩座30之中，且可由该内横管31处控制其嵌入或脱离该两管座10的多个内定位孔14的其中一者，以达到将该两内伸缩管32定位于适当伸缩长度的目的。
在本实施例中，该两管座10分别由两管体并排结合而成，且内侧的管体短于外侧的管体，使一端可形成一空间供容纳该内横管31。当然该两管座10也可利用管体、杆体、片体等结构将其链接成一体或直接一体成型为一体，此仅是上述实施例的简单延伸设计，故不再另加以赘述。
请再配合参阅图3～5所示，指出：
该两外伸缩管22，外侧面靠近末端处分别各设有贯通到内部的一外穿孔23。
该两内伸缩管32，外侧面靠近末端处分别各设有贯通到内部的一内穿孔33。
该外定位装置40，包含一外压钮41、多个外弹簧42、两外枢柱43及两外定位杆44。该外压钮41可活动地设于该外横管21之中。该多个外弹簧42设于该外压钮41与该外横管21之间，可提供弹力使该外压钮41部份凸露出该外横管21的内侧面。该两外枢柱43直立地结合于该两外伸缩管22与该外横管21的交接处内部。该两外定位杆44分别对称地设于该两外伸缩管22内，每一外定位杆44包含有一外勾段440、一外延伸段441及一外枢环442，该外勾段440的一端具有一外勾部443可供穿设于外穿孔23及相对应的该外定位孔13之中以产生定位的作用，该外延伸段441由该外勾段440的另一端延伸到该外横管21之中，且端部与该外压钮41可略为活动地连结。该外枢环442结合在该外勾段440与该外延伸段441的交接处，且可转动地套设于该外枢柱43上。当将该外压钮41压入该外横管21时会连动该两外定位杆44分别以该外枢柱43为轴心摆动，以使该外勾部443脱离相对
应的该外定位孔13，进而使该两外伸缩管22能于该两外滑孔11中伸缩；当伸缩至预定长度时，放开该外压钮41，则该多个外弹簧42会使该外压钮41弹回原位，同时会连动该两外定位杆44分别以该外枢柱43为轴心摆动，以使该外勾部443插入相对应的该外定位孔13，以达到伸缩定位的目的。
该内定位装置50，包含一内压钮51、多个内弹簧52、两内枢柱53及两内定位杆54。该内压钮51可活动地设于该内横管31之中。该多个内弹簧52设于该内压钮51与该内横管31之间，可提供弹力使该内压钮51部份凸露出该内横管31的内侧面。该两内枢柱53直立地结合于该两内伸缩管32与该内横管31的交接处内部。该两内定位杆54分别对称地设于该两内伸缩管32内，每一内定位杆54包含有一内勾段540、一内延伸段541及一内枢环542，该内勾段540的一端具有一内勾部543可供穿设于内穿孔33及相对应的该内定位孔14之中以产生定位的作用，该内延伸段541由该内勾段540的另一端延伸到该内横管31之中，且端部与该内压钮51可略为活动地连结。该内枢环542结合在该内勾段540与该内延伸段541的交接处，且可转动地套设于该内枢柱53上。当将该内压钮51压入该内横管31时会连动该两内定位杆54分别以该内枢柱53为轴心摆动，以使该内勾部543脱离相对应的该内定位孔14，进而使该两内伸缩管32能于该两内滑孔12中伸缩；当伸缩至预定长度时，放开该内压钮51，则该多个内弹簧52会使该内压钮51弹回原位，同时会连动该两内定位杆54分别以该内枢柱53为轴心摆动，以使该内勾部543插入相对应的该内定位孔14，以达到伸缩定位的目的。
如此，当无需增加承载空间时，便可将该外伸缩座20与该内伸缩座30收合于该两管座10的两侧呈收合状态，以缩小体积，减少空间的占用(如图4、5所示)。当需增加承载空间时，便可将该外伸缩座20与该内伸缩座30于该两管座10的两侧拉出呈伸张状态，以使可增加承载空间供载运物品(如图2、3所示)。
请参阅图6、7所示，为本发明应用于一行李箱60的实施例。其中指出，可将该两管座10结合固定在该行李箱60的底部，然后于该
两管座10、该外伸缩座20及该内伸缩座30的底部设置多个轮子61。当无需额外增加承载空间时，便可将该外伸缩座20与该内伸缩座30收合于该两管座10的两侧呈收合状态，以缩小体积减少空间的占用，并作为一般行李箱使用。当需额外增加承载空间时，便可将该外伸缩座20与该内伸缩座30于该两管座10的两侧拉出呈伸张状态，以使可增加承载空间供载运物品。而且，该两管座10可依不同需要而以不同方向结合在该行李箱60的底部，以使外伸缩座20及该内伸缩座30可朝前、后伸缩(如图6所示)，或是朝两侧伸缩(如图7所示)。
请参阅图8、9所示，为本发明应用于一推车70的实施例。其中指出，可将该两管座10结合固定在该推车70的附加电路板71上。当无需额外增加承载空间时，便可将该外伸缩座20与该内伸缩座30收合于该两管座10的两侧呈收合状态，以缩小体积减少空间的占用，并作为一般推车使用。当需额外增加承载空间时，便可将该外伸缩座20与该内伸缩座30于该两管座10的两侧拉出呈伸张状态，以使可增加承载空间供载运物品。而且，该两管座10可依不同需要而以不同方向结合在该推车70的附加电路板71上，以使外伸缩座20及该内伸缩座30可朝前、后伸缩(如图8所示)，或是朝两侧伸缩(如图9所示)。
本发明所提供的可扩充空间的延伸座体，当无需增加承载空间时，便可将该外伸缩座20与该内伸缩座30收合于该两管座10的两侧呈收合状态，以缩小体积，减少空间的占用。反之，当需增加承载空间时，则可将该外伸缩座20与该内伸缩座30于该两管座10的两侧拉出呈伸张状态，以大幅增加承载空间供载运物品。且当应用于行李箱60时，则可分别于该两管座10、该外伸缩座20及该内伸缩座30的底部设置多个轮子61，使其于伸张状态时，可分别藉由底部的轮子61的良好支撑而具有较佳的承载稳定性。特别是，本发明的结构较为简单，而制作成本低廉，组装上也非常的简单、方便及快速。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围
之内。
