其中，底座2的中部设有圆柱，旋转盘3的中部设有旋转孔，底座2和旋转盘3通过圆柱与旋转孔的配合来实现相互旋转连接；第一侧释锁件10和第二侧释锁件20相互对称设置在底座2的左右两侧，释锁拉手4前后移动的过程中，第一侧释锁件10和第二侧释锁件20可以在左右方向上相互靠近和远离，以此来实现旋转盘3相对于底座2旋转到90°位置时前卡钩5和后卡钩6的释锁和锁定，结构简单可靠，操作方便。
在旋转盘3相对于底座2旋转到90°位置时并需要解锁椅身1时，使用者先作用力于释锁拉手4上以拉动释锁拉手4向前移动，使得第一侧拨块101带动前驱动块711左移，以及同时使得第二侧拨块201带动后驱动块811右移，后驱动块811移动带动后钩锁止限位杆82移动以使后钩锁止限位杆82与后卡钩6相互脱离，前驱动块711移动带动前钩锁止限位杆72移动以使前钩锁止限位杆72与前卡钩5相互脱离，从而实现前卡钩5和后卡钩6同时释锁，完成椅身1的解锁。
可选地，结合图1至图7、图14至图19所示，所述释锁拉手4设有第一圆柱43和第二圆柱44，所述第一侧释锁件10设有与所述第一圆柱43滑动配合的第一侧斜槽102，所述第二侧释锁件20设有与所述第二圆柱44滑动配合的第二侧斜槽202，所述底座2设有供所述第一侧释锁件10和所述第二侧释锁件20左右滑动的导轨21。
其中，第一侧斜槽102的前端向右倾斜，使得释锁拉手4前移时第一侧释锁件10向左移动，第二侧斜槽202的前端向左倾斜，使得释锁拉手4前移时第二侧释锁件20向右移动；第一侧斜槽102和第二侧斜槽202均具有一定的长度，以便第一圆柱43能在第一侧斜槽102内滑动以及第二圆柱44能在第二侧斜槽202内滑动；第一侧斜槽102的宽度与第一圆柱43的外径相近，第二侧斜槽202的宽度与第二圆柱44的外径相近，以尽量减少结构的窜动。
椅身1被锁定时，第一圆柱43位于第一侧斜槽102的后端，第二圆柱44位于第二侧斜槽202的后端，当拉动释锁拉手4时，第一侧释锁件10通过与导轨21的配合及通过第一侧斜槽102与第一圆柱43的配合实现左移，从而也带动前钩释锁驱动件71左移，最终实现前卡钩5释锁，同时第二侧释锁件20通过与导轨21的配合及通过第二侧斜槽202与第二圆柱44的配合实现右移，从而也带动后钩释锁驱动件81右移，最终实现后卡钩6释锁。
本实施例中，在底座2上设置导轨21及在释锁拉手4上设置第一圆柱43和第二圆柱44，使得第一侧释锁件10和第二侧释锁件20在释锁拉手4前移释锁时只能沿着导轨21的长度方向移动，从而确保拉动释锁拉手4时前卡钩5和后卡钩6能被顺利释锁，结构简单，操作方便。
可选地，结合图1至图25所示，还包括拉压两用件50，所述旋转盘3与所述底座2旋转连接，所述释锁拉手4和所述拉压两用件50均与所述底座2活动连接，所述底座2还活动连接有与所述旋转盘3锁定的旋转释锁组件60，所述旋转释锁组件60和所述释锁拉手4均与所述拉压两用件50活动连接；当向下按压所述拉压两用件50时，所述旋转释锁组件60与所述旋转盘3脱离以实现所述旋转盘3的旋转释锁，当向前拉动所述拉压两用件50时，所述拉压两用件50带动所述释锁拉手4移动以解锁所述椅身1。
其中，旋转盘3上可拆卸安装有椅身，当拉压两用件50处于初始状态时，椅身与旋转盘3锁定使得椅身牢固安装，旋转盘3与旋转释锁组件60锁定使得旋转盘3不能相对于底座2旋转，即使得椅身不能相对于底座2旋转；释锁拉手4向前移动时能使得椅身与旋转盘3之间的锁定结构被释锁，从而实现椅身能从旋转盘3上被拆卸下来；旋转释锁组件60受到压力作用移动时能与旋转盘3相互脱离，从而实现旋转盘3在旋转方向的释锁使得椅身可进行旋转。
本实施例中的具有联动释锁功能的儿童安全座椅，通过设置一个拉压两用件50，并通过按压拉压两用件50和拉动拉压两用件50这两个动作，来分别实现椅身旋转功能的释锁和椅身拆卸功能的释锁，不仅部件少，成本低，且释锁的操作也很便捷，能轻松完成两个功能的释锁。
可选地，结合图20至图25所示，当向下按压所述拉压两用件50时，所述旋转释锁组件60与所述旋转盘3脱离以实现所述旋转盘3的旋转释锁；所述底座2设有腰型槽23，所述拉压两用件50设有与所述腰型槽23活动连接的第一销轴501，当向下按压所述拉压两用件50时，所述拉压两用件50绕着所述第一销轴501转动，所述第一销轴501与所述腰型槽23旋转连接；当向前拉动所述拉压两用件50时，所述第一销轴501在所述腰型槽23内向前移动，所述第一销轴501与所述腰型槽23滑动连接。
其中，腰型槽23具有一定的长度，其长度方向与拉压两用件50的前后移动方向一致，以便实现拉压两用件50相对于底座2进行前后移动；腰型槽23的宽度大小与第一销轴501的外径相近，以方便实现拉压两用件50绕第一销轴501进行旋转；通过第一销轴501与腰型槽23的配合，来按压实现拉压两用件50的旋转动作及拉动实现拉压两用件50的平移，结构简单，动作实现可靠。
可选地，结合图21、图23至图25所示，当需要向下按压所述拉压两用件50来实现所述旋转盘3的旋转释锁时，所述第一销轴501与所述腰型槽23的后端抵接。
其中，腰型槽23前后两端的半圆的直径与第一销轴501的外径相近，当向前拉动拉压两用件50时，第一销轴501会移动到腰型槽23的前端位置，此时可实现椅身拆卸功能的释锁；拉压两用件50在可以进行旋转盘3的旋转释锁操作时，将第一销轴501设计成与腰型槽23的后端进行抵接，一方面使得拉压两用件50在转动过程中绕第一销轴501旋转的轴线位置相对于底座2固定，不易跑偏，确保拉压两用件50能始终作用于旋转释锁组件60，另一方面使得实现椅身旋转功能释锁时和椅身拆卸功能释锁时，第一销轴501在腰型槽23内的位置不同，使得两个功能的释锁可以单独进行，从而防止两个功能释锁时发生相互干扰。
可选地，结合图20至图23所示，所述旋转释锁组件60包括旋转释锁块601和旋转释锁弹性件602，所述旋转释锁块601设有第二销轴6013，所述底座2设有与所述第二销轴6013铰接连接的铰接孔22，所述旋转释锁弹性件602的两端分别与所述旋转释锁块601和所述底座2连接，所述旋转释锁块601与所述拉压两用件50抵接；当未向下按压所述拉压两用件50时，所述旋转释锁块601与所述旋转盘3锁定；当向下按压所述拉压两用件50时，所述旋转释锁块601受到向下压力并绕所述第二销轴6013发生转动后与所述旋转盘3脱离，以实现所述旋转盘3的旋转释锁。
其中，拉压两用件50设有倾斜设置的拨动杆，拨动杆与旋转释锁块601配合使用；第二销轴6013设置在旋转释锁块601的前端，旋转释锁块601的后端与旋转盘3锁定，旋转释锁弹性件602为压缩弹簧，旋转释锁弹性件602的上端与旋转释锁块601的后端下表面抵接，使得在拉压两用件50撤销按压时，在旋转释锁弹性件602的弹力作用下旋转释锁块601的后端能牢固与旋转盘3进行锁定；当按压拉压两用件50时，拉压两用件50能推动旋转释锁块601绕着第二销轴6013转动，旋转释锁块601的后端会与旋转盘3脱离，实现对旋转盘3的旋转释锁，从而实现椅身旋转的功能。
可选地，结合图20、图22所示，所述旋转盘3的边缘间隔设有多个安装槽33，多个所述安装槽33择一与所述旋转释锁块601插接锁定连接。设置多个间隔设置的安装槽33，使得椅身可以旋转锁定在多个位置，通过安装槽33与旋转释锁块601插接连接实现锁定，结构简单，且在旋转释锁块601受到拉压两用件50的按压作用时能顺利从安装槽33内脱出，结构可靠。
可选地，结合图20至图25所示，所述旋转释锁块601开设有让位槽6012，以使向前拉动所述拉压两用件50时所述拉压两用件50与所述旋转释锁块601脱离。
其中，当旋转释锁块601与旋转盘3锁定时，旋转释锁块601处于前低后高的倾斜状态，让位槽6012开设在旋转释锁块601的上表面，拉压两用件50在初始状态时拉压两用件50的后端刚好能与旋转释锁块601的后端位置接触或挨近，这样在向前移动拉压两用件50时，原本与旋转释锁块601前端接触或挨近的拉压两用件50在向前移动后能与旋转释锁块601脱离，因此在释锁椅身拆卸功能时不会与旋转释锁块601产生干涉，确保释锁的有效性和稳定性。
可选地，结合图23所示，所述旋转释锁块601设有与所述拉压两用件50后端抵接的凸起6011。凸起6011设置在旋转释锁块601的上表面，且靠近旋转释锁块601的后端进行设置，以确保拉压两用件50能推动旋转释锁块601绕第二销轴6013转动，增加转动的行程。

其中，拉压两用件50的上表面设有供用户手指放置的凹槽，以便用户能顺利向前拉动拉压两用件50；拉压两用件50在初始状态时或向下按压拉压两用件50时，抵接台45不与抵接面502接触，防止两个功能释锁时产生干扰，只有向前拉动拉压两用件50时，抵接台45才与抵接面502接触，在抵接面502的推力作用下，释锁拉手4实现向前移动，完成对椅身拆卸功能的释锁。
可选地，结合图20至图29所示，包括相互旋转连接的底座2和旋转盘3，所述底座2连接有与所述旋转盘3锁定的旋转释锁块601，所述旋转释锁块601设有第一铰接部，第一铰接部优选为第二销轴6013，所述底座2设有与所述第一铰接部铰接连接的第二铰接部，第二铰接部优选为铰接孔22，当所述旋转释锁块601受到向下压力并绕所述第一铰接部发生转动后与所述旋转盘3脱离，以实现所述旋转盘3释锁。
其中，第二销轴6013可以为轴，则铰接孔22为轴孔，除此之外第二销轴6013也可为轴孔，则铰接孔22为轴，通过轴与轴孔的配合实现旋转释锁块601与底座2之间的铰接连接；第二销轴6013设置在旋转释锁块601的一端，在未受到向下压力时旋转释锁块601的另一端与旋转盘3锁定，当受到向下压力时旋转释锁块601的另一端与旋转盘3脱离，实现旋转盘3释锁，即解锁了椅身旋转的功能。第二销轴6013设置在旋转释锁块601的前端，第二销轴6013的外径与铰接孔22的内径尺寸相近，第二销轴6013能在铰接孔22内自由转动，通过第二销轴6013与铰接孔22的配合来实现旋转释锁块601与底座2的铰接连接，结构简单可靠，组装方便。
本实施例中的具有联动释锁功能的儿童安全座椅，设置与底座2铰接连接的旋转释锁块601，并通过旋转释锁块601与旋转盘3锁定，当旋转释锁块601受到向下压力时会与旋转盘3脱离实现旋转盘3的解锁，结构简单，部件少，操作方便。
可选地，结合图28所示，所述第二销轴6013的周壁上设有缺口60131。缺口60131的数量为四个，四个缺口60131对称均匀设置，设置缺口60131能减少第二销轴6013与铰接孔22的接触面积，能降低旋转释锁块601相对于底座2转动时所产生的噪音。
可选地，结合图20至图29所示，还包括旋转释锁弹性件602，所述旋转释锁弹性件602的两端分别与所述旋转释锁块601和所述底座2连接。旋转释锁弹性件602为压缩弹簧，旋转释锁弹性件602的上端与旋转释锁块601的后端下表面抵接，使得未受到向下压力时，在旋转释锁弹性件602的弹力作用下旋转释锁块601的后端能牢固与旋转盘3进行锁定。

可选地，结合图20至图29所示，所述安装槽33为L型槽，所述旋转释锁块601设有插接部6014，当所述旋转释锁块601与所述旋转盘3锁定时，所述插接部6014的上表面与所述L型槽插接抵接连接。
其中，L型槽一部分与旋转盘3的旋转平面平行、另一部分与旋转盘3的旋转平面垂直，当旋转释锁块601与旋转盘3锁定时，插接部6014的插入L型槽内，且插接部6014的上表面与L型槽中与旋转盘3旋转平面垂直的那部分抵接配合，不仅确保旋转释锁块601能牢固插接在旋转盘3内，且旋转释锁块601向下转动时能顺利与旋转盘3的安装槽33脱离，不会与安装槽33的其他部位产生干涉，方便解锁。
旋转释锁块601置于底座2与旋转盘3之间，旋转释锁块601的下方设有旋转释锁弹性件602，当旋转盘3旋转到所设位置时，旋转释锁弹性件602推动旋转释锁块601自动复位插入旋转盘3上所预设的安装槽33内，达到旋转限位锁止的作用；当旋转释锁块601受外力向下按压时，旋转释锁块601将绕底座2向下旋转运动，旋转释锁块601预先插入旋转盘3安装槽33中的插接部6014将自动脱离其限位位置，达到解锁旋转功能，当旋转盘3再旋转到另一所设位置时，旋转释锁弹性件602推动旋转释锁块601自动复位插入旋转盘3上所预设的另一安装槽33内，又可达到旋转限位锁止作用。
