具体实施方式
为了更清楚的阐释本申请的整体构思，下面再结合说明书附图以示例的方式进行详细说明。
需说明，在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
另外，在本申请的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或组件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连，可以是两个组件内部的连通或两个组件的相互作用关系。但注明直接连接则说明连接地两个主体之间并不通过过度结构构建连接关系，只通过连接结构相连形成一个整体。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。
本申请的扣具100可应用到如儿童推车、儿童安全座椅、婴幼儿背带等产品上，但本申请不以此为限。
以下将描述本申请的第一实施例。
参见图1和图2，扣具100可包括第一扣件1和第二扣件2。第二扣件2上可设有释锁操作件3。第一扣件1和第二扣件2可沿第三方向Z彼此对插配合，从而彼此锁定而不可分离。释锁操作件3可被致动，从而使第一扣件1和第二扣件2解锁。释锁操作件3可沿第一方向X设置在第二扣件2上，并且释锁操作件3可伸出第二扣件2。需指出，在本申请中，“第一扣件”和“第二扣件”仅用于区分两个扣件，而并非具有特定的含义，“第一扣件”和“第二扣件”的名称也可互换。释锁操作件3整体上可形成为沿第一方向X延伸的长条形。释锁操作件3的两端可被按压而被压缩。第一扣件1的体积可大于第二扣件2的体积，但本申请不以此为限。
参见图1，第一扣件1的一端(例如，沿第二方向Y的一端)可具有连接孔111。连接孔111可以是长方形的通孔。连接杆112可沿第一方向X在连接孔111内延伸。第一扣件1可借助连接孔111和连接杆112而以可调整的方式连接一系带(未示出)。例如，系带可从连接杆112的一侧沿一个方向穿过连接孔111，然后绕过连接杆112并从连接杆112的另一侧沿相反方向穿过连接孔111，最后再次绕过连接杆112并从连接杆112的上述一侧沿上述一个方向再次穿过连接孔111。以上的系带穿过连接孔111的方式仅为示例，系带还可以其他方式穿过连接孔111，本申请不以此为限。当系带被束缚到连接孔111和连接杆112之后，第一扣件1可连接到系带，并且连接到第一扣件1的系带的长度可被调整。替代地，连接孔111内可不具有连接杆112或者具有彼此平行且相距一定距离的两个连接杆112。
参见图2，第二扣件2的两端(例如，沿第二方向Y的两端)均可具有连接孔211。两根系带可分别穿过两个连接孔211而连接到第二扣件2。在本实施例中，第二扣件2可以是固定的，而第一扣件1可以是活动的，但本申请不以此为限。替代地，连接孔211内也可设置连接杆。
参见图3，第一扣件1可具有第一扣件壳体11和第一扣件本体12。第一扣件壳体11可具有内部空间，并且第一扣件本体12可设置在第一扣件壳体11的内部空间。第一扣件本体12可形成为框架。第一扣件1可设有第一磁体5。第二扣件2可设有第二磁体6。第一扣件壳体11可包括凸台113。凸台113可具有圆形的第一凸台部1131和从第一凸台部1131沿径向向外伸出的第二凸台部1132。
参见图3、图4和图4A，第一扣件本体12可形成为近似长方形的框架。第一扣件本体12可包括外框架121以及连接外框架121的第一侧和第二侧(沿第二方向Y的两侧)的连接臂123。连接臂123可沿第二方向Y延伸，并且连接臂123的两端可连接到外框架121。连接臂123可平分第一扣件本体12。连接臂123上可具有第一磁体容置部122。第一磁体容置部122可用于容纳第一磁体5。第一磁体容置部122可将连接臂123分成第一连接臂部1231和第二连接臂部1232。在本实施例中，第二连接臂部1232的长度可以比第一连接臂部1231的长度更长，但本申请不以此为限。外框架121可包括凸耳部1211，凸耳部1211可向上突起，从而对应于第二凸台部1132凸出的距离。外框架121相对的两个拐角处可分别具有凹入部1212。外框架121在凹入部1212处可具有锁定弹臂1217。锁定弹臂1217沿第二方向Y延伸，且具有一自由末端。锁定弹臂1217的自由末端上形成阻挡柱1215。阻挡柱1215在锁定弹臂1217上沿第三方向Z延伸。第一扣件壳体11的内侧可具有限位阻挡凸起115。限位阻挡凸起115沿第一方向X向第一扣件壳体11的内部延伸。当第一扣件本体12固定在第一扣件壳体11内时，阻挡柱1215与限位阻挡凸起115抵接，以阻止第一扣件本体12离开第一扣件壳体11的内部。限位阻挡凸起115上可具有导向斜面1151。相应地，阻挡柱1215上可具有配合斜面1216。导向斜面1151可位于限位阻挡凸起115远离阻挡柱1215的一侧。当第一扣件本体12沿第二方向Y插入第一扣件壳体11时，导向斜面1151接触配合斜面1216以使得锁定弹臂1217弹性变形，以允许第一扣件本体12进入到第一扣件壳体11内部。外框架121沿第一方向X的两侧的下部可分别具有第一被卡合部1213和第二被卡合部1214。也就是说，相对于连接臂123来说，第一被卡合部1213和第二被卡合部1214分别形成在外框架121的第三侧和第四侧。
继续参见图3和图4，释锁操作件3可包括第一按钮31、第二按钮32、第一卡合部33、第二卡合部34和弹性部35。第一按钮31和第二按钮32可位于释锁操作件3的两端。第一按钮31和第二按钮32可形成为长方体的形状，但本申请不以此为限。第一按钮31的内侧可具有第一卡合部33。第二按钮32的内侧可具有第二卡合部34。第一卡合部33和第二卡合部34可分别沿垂直于第一按钮31和第二按钮32的移动方向延伸。换言之，第一卡合部33和第二卡合部34可沿第三方向Z向上延伸。第一卡合部33和第二卡合部34可分别形成为沿第一方向X且径向向外(或彼此背离)的钩部。弹性部35可位于第一卡合部33和第二卡合部34之间。第一卡合部33和第二卡合部34可通过径向向外卡合第一扣件1的内周而将第一扣件1与第二扣件2锁定。具体地，第一卡合部33和第二卡合部34可分别与第一被卡合部1213和第二被卡合部1214卡合。
在另一实施例中，第一扣件1上可设有释锁操作件3，并且第一卡合部33和第二卡合部34可通过径向向外卡合第二扣件2的内周而将第一扣件1与第二扣件2锁定。
可以理解，在一些实施例中，第一按钮31、第二按钮32、第一卡合部33、第二卡合部34和弹性部35可以一体成型。在其他实施例中，释锁操作件3可仅具有第一卡合部33或第二卡合部34。相应地，第一扣件本体12可仅具有第一被卡合部1213或第二被卡合部1214。
弹性部35可包括中间部352和位于中间部352两侧的多个弹臂351。多个弹臂351的每一个可具有弯曲的形状。第一按钮31和第二按钮32朝向沿第一方向彼此移动引起多个弹臂351弹性变形。例如，中间部352的两侧分别可具有两个弹臂351。每个弹臂351的一端可连接到中间部352，每个弹臂351的另一端可连接到第一按钮31、第二按钮32、第一卡合部33和第二卡合部34中的一个。又例如，弹性部35整体上可形成为类似数字“8”的形状。释锁操作件3可以一体成型。
在其他实施例中，中间部352的两侧分别可具有一个、三个或四个弹臂351。在其他未示出的实施例中，中间部352可以省略，第一按钮31和第二按钮32可以通过弹臂351连接。
第二扣件2可具有第二扣件本体21。第二扣件本体21上可居中地设有第二磁体容置部212。第二磁体容置部212用于容纳第二磁体6。第二扣件本体21可具有缺口部213。具体地，第二磁体容置部212沿第一方向X的两侧可分别具有一个缺口部213。第一按钮31和第二按钮32可至少部分地位于缺口部213。如图4所示，内缺口部213可为第一按钮31、第二按钮32、第一卡合部33和第二卡合部34的移动提供空间。
参见图3和图5，第一磁体5被固定在第一磁体容置部122和第一容置部盖1221所包围的空间内。第一磁体6被固定在第二磁体容置部212和第二容置部盖2121所包围的空间内。弹性部35可通过中间部352固定到第二扣件2。中间部352可具有孔3521。孔3521可以是螺孔，并且释锁操作件3可通过螺钉(未示出)固定到第二容置部盖2121。这样，当按压第一按钮31和/或第二按钮32时，对应的弹臂351收缩变形，并且第一按钮31和/或第二按钮32朝向中间部352移动。在其他实施例中，释锁操作件3可通过其他方式(例如，铆钉、卡扣配合，等等)固定在第二扣件2上。当第一扣件1与第二扣件2彼此锁定时，第一磁体5靠近第二磁体6，并且第一磁体5和第二磁体6沿对插配合的方向(即，第三方向Z)至少部分地重叠，使得第一磁体5和第二磁体6的磁力能够互相影响。第一磁体5和第二磁体6面向彼此的磁极可以是相反的，从而产生吸引力，以在第一按钮31和第二按钮32被误触时保持第一扣件1与第二扣件2彼此不分离。替代地，第一磁体5和第二磁体6面向彼此的磁极可以是相同的，从而产生排斥力。
第一扣件壳体11的下方可设有开口，以供第二扣件2和释锁操作件3的至少一部分沿第三方向Z从下向上至少部分地插入第一扣件1内。第一被卡合部1213上可具有第一斜面12131，第二被卡合部1214上可具有第一斜面12141。第一卡合部33上可具有第二斜面331，第二卡合部34上可具有第二斜面341。
当第二扣件2沿第三方向Z从下向上插入第一扣件1内时，第二斜面331、341分别接触第一斜面12131、12141，使得第一斜面12131、12141沿径向向内的方向致动第二斜面331、341，从而引起弹臂351弹性变形而收缩。这样，第一卡合部33和第二卡合部34将不会阻挡第二扣件2进一步插入到第一扣件1内。当第一卡合部33和第二卡合部34移动到第一被卡合部1213和第二被卡合部1214的上方时，弹臂351由于自身的弹性回复力而恢复到未变形的状态，此时第一被卡合部1213和第二被卡合部1214将阻挡第一卡合部33和第二卡合部34沿第三方向Z向下移动，使得第二扣件2与第一扣件1彼此锁定。在第一卡合部33和第二卡合部34恰好移动到第一被卡合部1213和第二被卡合部1214的上方时，第二磁体容置部212抵接第一磁体容置部122从而阻止第二扣件2进一步插入到第一扣件1内。
当需要使第一扣件1与第二扣件2解锁时，可沿第一方向X径向向内分别按压第一按钮31和第二按钮32，此时第一卡合部33和第二卡合部34随着第一按钮31和第二按钮32径向向内移动而不被第一被卡合部1213和第二被卡合部1214阻挡。然后，克服第一磁体5和第二磁体6的磁性吸引力而将第二扣件2从第一扣件1的内部拔出，从而分离第二扣件2和第一扣件1。也就是说，第一按钮31和第二按钮32彼此移动，带动第一卡合部33和第二卡合部34彼此靠近而释锁。
以下将描述本申请的第二实施例。
参见图6和图7，扣具100可包括第一扣件1和第二扣件2。第二扣件2上可设有释锁操作件3。第一扣件1和第二扣件2可沿第三方向Z彼此对插配合，从而彼此锁定而不可分离。释锁操作件3可被致动，从而使第一扣件1和第二扣件2解锁。释锁操作件3可沿第一方向X设置在第二扣件2上，并且释锁操作件3可伸出第二扣件2。释锁操作件3整体上可形成为沿第一方向X延伸的长条形。释锁操作件3的两端可被按压而被压缩。第一扣件1的体积可大于第二扣件2的体积，但本申请不以此为限。
第二实施例的连接孔111、211和连接杆112可参见第一实施例。
参见图8，第一扣件1可具有第一扣件壳体11。第一扣件壳体11可具有内部空间，并且外框架121可设置在第一扣件壳体11的内部空间。第一扣件1可设有第一磁体5。第二扣件2可设有第二磁体6。可以理解的是，第二实施例也可以不设置外框架121。
第一磁体5可被固定在第一磁体容置部122和第一容置部盖1221所包围的空间内。第一磁体6可被固定在第二磁体容置部212和第二容置部盖2121所包围的空间内。第二实施例的弹性部35可以与第一实施例中的相同。第二实施例的弹性部35的结构及其与第二扣件2的连接方式可参见第一实施例。第二实施例的第一磁体5和第二磁体6的相互作用可参见第一实施例。第二实施例与第一实施例的区别在于第一卡合部33和第二卡合部34可以分别与第一扣件壳体11卡合。
第一扣件壳体11的下方可包括下边缘114。下边缘114的内侧可限定开口，以供第二扣件2和释锁操作件3的至少一部分沿第三方向Z从下向上至少部分地插入第一扣件1内。第一卡合部33上可具有第二斜面331，第二卡合部34上可具有第二斜面341。
当第二扣件2沿第三方向Z从下向上插入第一扣件1内时，第二斜面331、341分别接触开口两侧的下边缘114，使得下边缘114沿径向向内的方向致动第二斜面331、341，从而引起弹臂351弹性变形而收缩。这样，第一卡合部33和第二卡合部34将不会阻挡第二扣件2进一步插入到第一扣件1内。当第一卡合部33和第二卡合部34移动到第一被卡合部1213和第二被卡合部1214的上方时，弹臂351由于自身的弹性回复力而恢复到未变形的状态，此时下边缘114将阻挡第一卡合部33和第二卡合部34沿第三方向Z向下移动，使得第二扣件2与第一扣件1彼此锁定。在第一卡合部33和第二卡合部34恰好移动到第一被卡合部1213和第二被卡合部1214的上方时，第二磁体容置部212抵接第一磁体容置部122从而阻止第二扣件2进一步插入到第一扣件1内。
当需要使第一扣件1与第二扣件2解锁时，可沿第一方向X径向向内分别按压第一按钮31和第二按钮32，此时第一卡合部33和第二卡合部34随着第一按钮31和第二按钮32径向向内移动而不被下边缘114阻挡。然后，克服第一磁体5和第二磁体6的磁性吸引力而将第二扣件2从第一扣件1的内部拔出，从而分离第二扣件2和第一扣件1。
以下将描述本申请的第三实施例。
参见图9和图10，扣具100可包括第一扣件1和第二扣件2。第二扣件2上可设有释锁操作件3。第一扣件1和第二扣件2可沿第三方向Z彼此对插配合，从而彼此锁定而不可分离。释锁操作件3可被致动，从而使第一扣件1和第二扣件2解锁。释锁操作件3可设置在第二扣件2上，并且释锁操作件3可伸出第二扣件2的一侧。释锁操作件3的一端可被按压而滑动。第一扣件1的体积可小于第二扣件2的体积，但本申请不以此为限。
参见图9，第二扣件2的一端(例如，沿第二方向Y的一端)可具有连接孔231。连接孔231可以是长方形的通孔。枢轴234可沿第一方向X在连接孔231内延伸。第二扣件2可借助连接孔231和枢轴234而以可调整的方式连接一系带(未示出)。当系带被束缚到连接孔231和枢轴234之后，第二扣件2可连接到系带，并且连接到第二扣件2的系带的长度可被调整。替代地，连接孔231内可具有一个或多个连接杆。替代地，连接孔231内可不具有枢轴234。
参见图10，第一扣件1的两端(例如，沿第二方向Y的两端)均可具有连接孔111。两根系带可分别穿过两个连接孔111而连接到第一扣件1。替代地，连接孔111内可设置连接杆。
参见图11，第二扣件2可具有第二扣件壳体22和第二扣件外壳23。第二扣件外壳23可具有内部空间，并且第二扣件壳体22可设置在第二扣件外壳23的内部空间。第二扣件外壳23的侧部可具有壳体容纳孔233，以供第二扣件壳体22插入其中。第二扣件外壳23可具有两个枢轴孔232，以用于安装枢轴234。两个枢轴孔232可设置在连接孔231的两侧。释锁操作件3可部分地插入第二扣件壳体22内。
第一扣件1可具有第一扣件本体12。第一扣件本体12沿第二方向Y的两端可分别具有翼部124。翼部124可便于操作者用手捏住而控制第一扣件1。第一扣件本体12可设有锁合部125。锁合部125可位于第一扣件本体12的中心位置，但本申请不以此为限。第一扣件1可设有第一磁体5。第一磁体5可位于锁合部125的内部。第二扣件2可设有第二磁体6。第二扣件壳体22可具有第二磁体容置部221以容纳第二磁体6。
释锁操作件3可包括按钮31、臂部36、过渡部37和卡合部33。释锁操作件3可以一体形成。释锁操作件3可包括两个臂部36。两个臂部36可从按钮31向卡合部33平行地延伸，并且分别位于锁合部125沿第二方向Y的相反两侧。在其他实施例中，两个臂部36可彼此成角度地延伸。释锁操作件3仅包括一个按钮31，其可从第二扣件2在第一方向X上的一侧至少部分地伸出。卡合部33可形成为圆弧形。具体地，卡合部33可形成为半圆弧形。在其他实施例中，卡合部33可形成为大于半圆的圆弧形或小于半圆的圆弧形。卡合部33可以与锁合部125的外周的一部分卡合。释锁操作件3可包括两个过渡部37。两个过渡部37可分别将两个臂部36的一端连接到卡合部33的两端。两个过渡部37可相对于两个臂部36呈一角度，这样卡合部33与两个臂部36在第三方向Z上处于不同的平面。过渡部37可垂直于与其相连的臂部36或卡合部33，但本申请不以此为限。卡合部33在第三方向Z上的尺寸可小于臂部36在第三方向Z上的尺寸，即，卡合部33的厚度可小于臂部36的厚度。按钮31的厚度较大可以提高按钮31的强度，并为复位件7提供支撑点。卡合部33的厚度较小，从而便于和第一扣件1的锁合部125的锁合槽1251(以下将详细描述)卡合。在其他实施例中，臂部36的厚度可以与卡合部33的厚度相同。释锁操作件3可形成环形。换言之，按钮31、臂部36、过渡部37和卡合部33可合围一定的空间。锁合部125可位于该空间内。按钮31和卡合部33可分别位于锁合部125沿第一方向的相反两侧。
参见图11和图14，扣具100可包括复位件7。复位件7可以是螺旋弹簧，但本申请不以此为限。复位件7可设置在第二扣件2与释锁操作件3之间，以提供使卡合部33趋于与锁合部125卡合的复位力。按钮31的面向卡合部33的一侧形成有复位件容纳槽311。复位件7的一端可位于复位件容纳槽311内。复位件7的另一端可固定到第二扣件壳体22的弹簧安装部235。弹簧安装部235可位于第二扣件壳体22的内壁上。
参见图11和图14，锁合部125的内部可具有第一磁体容置部122。第一磁体容置部122可以是一侧敞开的凹部。盖体13可封闭第一磁体容置部122的敞开的一端，从而将第一磁体5固定在第一磁体容置部122内。位于第二磁体容置部221中的第二磁体6可分别被第二扣件外壳21和第二磁体容置部221固定。
参见图14和图15，锁合部125可从第一扣件本体12沿第三方向Z向上凸出。锁合部125可具有锁合槽1251和第三斜面1252。锁合部125可形成为圆柱形，并且锁合槽1251和第三斜面1252均在锁合部125的外周形成为一圈。锁合槽1251用于与卡合部33卡合。卡合部33可具有第二斜面331。第三斜面1252和第二斜面331可彼此配合以沿第一方向X致动卡合部33。
参见图12到图15，当第一扣件1沿第三方向Z从下向上插入第二扣件2内时，第三斜面1252可向上抵接第二斜面331，使得释锁操作件3克服复位件7的复位力而沿第一方向X向右移动。这样，卡合部33避开锁合部125，使得释锁操作件3可进一步向上移动。在锁合部125经过第三斜面1252后，复位件7将推动释锁操作件3，使得卡合部33进入到锁合槽1251。此时，第一扣件1与第二扣件2抵接，使得第一扣件1不能进一步进入第二扣件2，并且卡合部33被卡合在锁合槽1251中，使得第一扣件1不能与第二扣件2分离(即，第一扣件1与第二扣件2彼此锁定)。
当第一扣件1与第二扣件2彼此锁定时，第一磁体5沿第三方向Z靠近第二磁体6，并且第一磁体5和第二磁体6沿对插配合的方向(即，第三方向Z)至少部分地重叠，使得第一磁体5和第二磁体6的磁力能够互相影响。第一磁体5和第二磁体6面向彼此的磁极可以是相反的，从而产生吸引力，以在按钮31被误触时，保持第一扣件1与第二扣件2彼此不分离。替代地，第一磁体5和第二磁体6面向彼此的磁极可以是相同的，从而产生排斥力。
当需要使第一扣件1与第二扣件2解锁时，可沿第一方向X按压按钮31，此时按钮31克服复位件7的复位力而移动，使得卡合部33离开锁合槽1251。然后，克服第一磁体5和第二磁体6的磁性吸引力而将第一扣件1从第二扣件2的内部拔出，从而分离第一扣件1和第二扣件2。
以下将描述本申请的第四实施例。
参见图17和图18，扣具100可包括第一扣件1和第二扣件2。第二扣件2上可设有释锁操作件3。第一扣件1和第二扣件2可沿第三方向Z彼此对插配合，从而彼此锁定而不可分离。释锁操作件3可被致动，从而使第一扣件1和第二扣件2解锁。释锁操作件3可设置在第二扣件2上，并且释锁操作件3可伸出第二扣件2的一侧。释锁操作件3的一端可被按压而滑动。第一扣件1的体积可小于第二扣件2的体积，但本申请不以此为限。
参见图17，第二扣件2的一端(例如，沿第二方向Y的一端)可具有连接孔231。连接孔231可以是长方形的通孔。第二扣件2在连接孔231处可形成斜坡，使得越靠近边缘处的厚度越薄。枢轴234可沿第一方向X在连接孔231内延伸。连接孔231内可具有一个或多个连接杆236。第四实施例的连接杆236可参见第一实施例的连接杆112，在此不再赘述。替代地，连接孔231内可具有与第三实施例相同的枢轴。
参见图18，第一扣件1的两端(例如，沿第二方向Y的两端)均可具有连接孔111。第四实施例的连接孔111可与第三实施例相同，在此不再赘述。
参见图20，第二扣件2可具有内部空间。释锁操作件3可部分地插入第二扣件壳体22内。
参见图19和图20，第一扣件1可设有锁合部125。锁合部125可位于第一扣件1的中心位置，但本申请不以此为限。第一扣件1可设有第一磁体5。第一磁体5可位于锁合部125的内部。
释锁操作件3可设有第二磁体6。释锁操作件3可具有第二磁体容置部38以容纳第二磁体6。释锁操作件3可包括按钮31、臂部36和卡合部33。释锁操作件3可以一体形成。释锁操作件3可包括两个臂部36。两个臂部36可从按钮31向卡合部33平行地延伸，并且分别位于锁合部125沿第二方向Y的相反两侧。在其他实施例中，两个臂部36可彼此成角度地延伸。释锁操作件3仅包括一个按钮31，其可从第二扣件2在第一方向X上的一侧至少部分地伸出。卡合部33面向按钮31的一侧边缘可形成为圆弧形。具体地，卡合部33面向按钮31的一侧边缘可形成为半圆弧形。在其他实施例中，卡合部33面向按钮31的一侧边缘可形成为大于半圆的圆弧形或小于半圆的圆弧形。卡合部33可以与锁合部125的外周的一部分卡合。释锁操作件3在第三方向Z上的尺寸(即，厚度)可以是均匀的或者相等的。释锁操作件3可形成环形。换言之，按钮31、臂部36、卡合部33可合围一定的空间。锁合部125可位于该空间内。
第四实施例可具有与第三实施例相同的复位件7，在此不再赘述。
第四实施例的第一磁体5的设置方式与第三实施例相同，在此不再赘述。
参见图18到图20，第二扣件2可具有第二磁体容置部38。第二磁体容置部38可位于卡合部33远离按钮31的一侧。第二磁体容置部38可密封有第二磁体6。
第一磁体5和第二磁体6中的至少一个可以是长方体或立方体的形状。优选地，第一磁体5和第二磁体6均为长方体或立方体的形状。第一磁体5的体积可大于第二磁体6的体积，但本申请不以此为限。替代地，第一磁体5和第二磁体6中的一个可以是长方体或立方体的形状，而第一磁体5和第二磁体6中的另一个可以是圆柱体的形状。
当第一扣件1与第二扣件2彼此锁定时，第一磁体5和第二磁体6可沿第一方向X至少部分地重叠(即，沿第一方向X至少部分地对准)。
参见图19，锁合部125可从第一扣件本体12沿第三方向Z向下凸出。锁合部125可具有锁合槽1251和第三斜面1252。锁合部125可形成为圆柱形，并且锁合槽1251和第三斜面1252均在锁合部125的外周形成为一圈。锁合槽1251用于与卡合部33卡合。卡合部33可具有第二斜面331。第三斜面1252和第二斜面331可彼此配合以沿第一方向X致动卡合部33。
当第一扣件1沿第三方向Z从上向下插入第二扣件2内时，第三斜面1252可向下抵接第二斜面331，使得释锁操作件3克服复位件7的复位力而沿第一方向X向右移动。这样，卡合部33避开锁合部125，使得释锁操作件3可进一步向下移动。在锁合部125经过第三斜面1252后，复位件7将推动释锁操作件3，使得卡合部33进入到锁合槽1251。此时，第一扣件1与第二扣件2抵接，使得第一扣件1不能进一步进入第二扣件2，并且卡合部33被卡合在锁合槽1251中，使得第一扣件1不能与第二扣件2分离(即，第一扣件1与第二扣件2彼此锁定)。
当第一扣件1与第二扣件2彼此锁定时，第一磁体5沿第一方向X靠近第二磁体6，并且第一磁体5和第二磁体6沿第一方向Z至少部分地重叠，使得第一磁体5和第二磁体6的磁力能够互相影响。第一磁体5和第二磁体6面向彼此的磁极可以是相反的，从而产生吸引力，以在按钮31被误触时，保持第一扣件1与第二扣件2彼此不分离。具体地，参见图19，第一磁体5和第二磁体6可分别位于锁合槽1251和卡合部33沿第一方向X的两侧，以提高锁合槽1251与卡合部33锁定可靠性。
当需要使第一扣件1与第二扣件2解锁时，可沿第一方向X按压按钮31，此时按钮31克服复位件7的复位力以及第一磁体5和第二磁体6的磁性吸引力而移动，使得卡合部33离开锁合槽1251。然后，沿第三方向Z将第一扣件1从第二扣件2的内部拔出，从而分离第一扣件1和第二扣件2。
以下将描述本申请的第五实施例。
参见图21和图22，扣具100S可包括第二扣件1S和第一扣件2S。第二扣件1S上可设有释锁操作件3S。第二扣件1S和第一扣件2S可沿第三方向Z彼此对插配合，从而彼此锁定而不可分离。释锁操作件3S可被致动，从而使第二扣件1S和第一扣件2S解锁。释锁操作件3S可沿第三方向Z设置在第二扣件1S上，并且释锁操作件3S可伸出第二扣件1S。也就是说，如图21所示，释锁操作件3S可活动地设置在第二扣件1S的上侧。释锁操作件3S可以是圆形，但本申请不以此为限。
需指出，在本申请中，“第一扣件”和“第二扣件”仅用于区分两个扣件，而并非具有特定的含义，“第一扣件”和“第二扣件”的名称也可互换。
参见图21，第二扣件1S的一端(例如，沿第二方向Y的一端)可具有连接孔111S。连接孔111S可以是长方形的通孔。连接杆112S可沿第一方向X在连接孔111S内延伸。第二扣件1S可借助连接孔111S和连接杆112S而以可调整的方式连接一系带(未示出)。例如，系带可从连接杆112S的一侧沿一个方向穿过连接孔111S，然后绕过连接杆112S并从连接杆112S的另一侧沿相反方向穿过连接孔111S，最后再次绕过连接杆112S并从连接杆112S的上述一侧沿上述一个方向再次穿过连接孔111S。以上的系带穿过连接孔111S的方式仅为示例，系带还可以其他方式穿过连接孔111S，本申请不以此为限。当系带被束缚到连接孔111S和连接杆112S之后，第二扣件1S可连接到系带，并且连接到第二扣件1S的系带的长度可被调整。替代地，连接孔111S内可不具有连接杆112S或者具有彼此平行且相距一定距离的两个连接杆112S。
在本申请中第一方向X、第二方向Y和第三方向Z可以两两互相垂直。
参见图22，第一扣件2S的两端(例如，沿第二方向Y的两端)均可具有连接孔23S。两根系带可分别穿过两个连接孔23S而连接到第一扣件2S。在本实施例中，第一扣件2S可以是固定的，而第二扣件1S可以是活动的，但本申请不以此为限。替代地，连接孔23S内也可设置连接杆。
参见图23和图24，第二扣件1S可具有第二扣件壳体11S和第二扣件本体12S。第二扣件壳体11S可具有内部空间，并且第二扣件本体12S可设置在第二扣件壳体11S的内部空间。第二扣件本体12S可形成为框架。第二扣件1S可设有第一磁体5S。第一扣件2S可设有第二磁体6S。
第二扣件壳体11S的下方可设有开口，以供第一扣件2S的至少一部分沿第三方向Z从下向上至少部分地插入第二扣件1S内。

外框架121S可包括凸耳部1211S，凸耳部1211S可向上突起。外框架121S相对的两个拐角处可分别具有凹入部1212S。外框架121S在凹入部1212S处可具有锁定弹臂1217S。锁定弹臂1217S沿第二方向Y延伸，且具有一自由末端。锁定弹臂1217S的自由末端上形成阻挡柱1215S。阻挡柱1215S在锁定弹臂1217S上沿第三方向Z延伸。第二扣件壳体11S的内侧可具有限位阻挡凸起(未示出)。限位阻挡凸起沿第一方向X向第二扣件壳体11S的内部延伸。当第二扣件本体12S固定在第二扣件壳体11S内时，阻挡柱1215S与限位阻挡凸起抵接，以阻止第二扣件本体12S离开第二扣件壳体11S的内部。限位阻挡凸起上可具有导向斜面(未示出)。相应地，阻挡柱1215S上可具有配合斜面1216S。导向斜面可位于限位阻挡凸起远离阻挡柱1215S的一侧。当第二扣件本体12S沿第二方向Y插入第二扣件壳体11S时，导向斜面接触配合斜面1216S以使得锁定弹臂1217S弹性变形，以允许第二扣件本体12S进入到第二扣件壳体11S内部。
第一扣件2S可设有配锁部21S。配锁部21S可位于第一扣件2S的中心位置，但本申请不以此为限。第二扣件1S可设有锁定部125S和顶推斜面117S。顶推斜面117S可形成在第二扣件壳体11S的内表面上。锁定部125S可位于释锁操作件3S与顶推斜面117S之间。释锁操作件3S可包括释锁顶推部32S。释锁顶推部32S可形成为圆环形，但本申请不以此为限。释锁顶推部32S可沿第三方向Z延伸。锁定部125S可包括能与配锁部21S锁定的锁头1253S。如图24所示，释锁顶推部32S、锁头1253S和顶推斜面117S可沿第三方向Z至少部分地对齐，但本申请不以此为限。顶推斜面117S和释锁操作件3S可位于锁头1253S沿第三方向Z的两侧。
在其他实施例中，释锁操作件3S、锁定部125S和顶推斜面117S可设置在第一扣件2S上，配锁部21S可设置在第二扣件1S上。
释锁操作件3S可沿第二扣件1S与第一扣件2S对插配合的方向(即，第三方向Z)对锁头1253S施加压力，使得锁头1253S沿着顶推斜面117S远离所述配锁部21S移动，从而与配锁部21S解除锁定。也就是说，如图24所示，当释锁顶推部32S向下推动锁头1253S时，锁头1253S沿着顶推斜面117S沿第一方向X和第三方向Z(向外且向下)移动。具体地，释锁顶推部32S将推动锁头1253S的锁头受力部1257S(参见图23)。
参见图23，锁定部125S还可包括弹臂1254S。弹臂1254S可与锁头1253S一体形成且连接到所述第二扣件本体12S。在一些实施例中，锁定部125S处于锁定状态时，弹臂1254S可平行于连接臂123S。弹臂1254S可对锁头1253S施加趋于使锁头1253S与配锁部21S锁定的弹力。弹臂1254S可以弹性变形。
在本实施例中，第二扣件1S可包括两个锁定部125S，每个锁定部125S可包括一个弹臂1254S和一个锁头1253S。两个锁定部125S可对称地位于连接臂123S的两侧。两个锁定部125S的锁头1253S可共同围绕第一磁体容置部122S的外周的大部分。
参见图24，锁头1253S上可形成锁头平面1255S和锁头斜面1256S。配锁部21S可具有顶推部211S、锁定槽212S和配锁部开口213S。顶推部211S上可形成配锁斜面2111S和锁定平面2112S。当第一扣件2S与第二扣件1S对插配合时，配锁斜面2111S与锁头斜面1256S配合以推动锁头1253S远离配锁部21S。然后，第一扣件2S与第二扣件1S可进一步靠近彼此并互相锁定。当第一扣件2S与第二扣件1S彼此锁定时，锁头平面1255S位于锁定槽212S内且抵接锁定平面2112S以形成锁定。当锁头1253S与配锁部21S解除锁定时，释锁操作件3S被按压，使得顶推斜面117S与锁头斜面1256S配合以推动锁头1253S远离配锁部21S。
参见图24，释锁操作件3S和第一磁体容置部122S之间可设置操作件复位件7S。操作件复位件7S可以是螺旋弹簧，但本申请不以此为限。操作件复位件7S可分别抵接释锁操作件3S的内表面和第一磁体容置部122S的复位件容纳部1223S。释锁操作件3S可包括通孔31S。通孔31S位于释锁操作件3S远离第二扣件1S的一侧(即，位于释锁操作件3S的上侧)。通孔31S可便于观察到第二扣件1S的内部，且便于安装、拆卸和维护。
参见图25，当第二扣件1S与第一扣件2S对插配合时，第一磁体5S与第二磁体6S可沿对插配合的方向(第三方向Z)至少部分地对齐，使得第一磁体5S和第二磁体6S的磁力能够互相影响。在本实施例中，第一磁体5S与第二磁体6S可在第二方向Y上部分地错开。在其他实施例中，第一磁体5S与第二磁体6S可在第一方向X上部分地错开，或者第一磁体5S与第二磁体6S可在第一方向X和第二方向Y上部分地错开。第一磁体5S和第二磁体6S面向彼此的磁极可以是相反的，从而产生吸引力，以在第一按钮31S和第二按钮32S被误触时保持第二扣件1S与第一扣件2S彼此不分离。替代地，第一磁体5S和第二磁体6S面向彼此的磁极可以是相同的，从而产生排斥力。
参见图26，配锁部开口213S可暴露第二磁体6S。也就是说，第二磁体容置部22S面向第一磁体容置部122S的一侧是敞开的，从而使第一磁体5S和第二磁体6S彼此更接近。可选地，第一磁体容置部122S面向第二磁体容置部22S的一侧是敞开的，或者第一磁体容置部122S和第二磁体容置部22S面向彼此的一侧均是敞开的。
以下将描述本申请的第六实施例。

参见图36，操作件容纳部24S可具有避让孔241S，以允许释锁顶推部32S穿过操作件容纳部24S。避让孔241S的数量可与释锁顶推部32S的数量相同。
参见图34A和图34B，第二扣件本体12S可具有避让凹部1218S。避让凹部1218S可形成在外框架121S的底部，以允许释锁顶推部32S穿过第二扣件本体12S。避让凹部1218S的数量可与释锁顶推部32S的数量相同。
参见图34C，第二扣件壳体11S可具有底部开口119S和避让凹部1218S。避让凹部1218S可靠近第二扣件壳体11S的底部，以允许释锁顶推部32S穿过并进入第二扣件壳体11S。避让凹部1218S的数量可与释锁顶推部32S的数量相同，也可以不同。配锁部21S可通过底部开口119S进入到第二扣件壳体11S内部。避让凹部1218S和底部开口119S可彼此连通，但本申请不以此为限。
参见图34A，扣具100S还包括锁头复位件8S。锁头复位件8S可设置在第二扣件本体12S的外框架121S与锁头1253S之间，以对锁头1253S施加趋于使锁头1253S与配锁部21S锁定的弹力。锁头复位件8S可以是螺旋弹簧，但本申请不以此为限。具体地，扣具100S包括两个锁头1253S和与两个锁头1253S对应的两个锁头复位件8S。两个锁头1253S可沿第一方向X设置在连接臂123S的两侧。锁头1253S可借助锁头复位件8S实现与配锁部21S的锁定或释锁。具体地，锁头1253S可借助锁头复位件8S连接第二扣件本体12S。锁头复位件8S一端抵接第二扣件本体12S的第三侧或第四侧(沿第一方向X的一侧)，并且锁头复位件8S的另一端抵接锁头1253S外侧中间位置，但本申请不以此为限。在其他未示出的实施例中，锁头1253S也可以通过其他固定结构可活动地设置于第二扣件1S内。
参见图34A到图36，当需要使第二扣件1S与第一扣件2S解锁时，按压释锁操作件3S。释锁操作件3S沿第二方向Y移动，使得释锁顶推部32S的顶推斜面321S抵接锁头1253S，并且将锁头1253S沿第一方向X向外侧推动，从而使锁头1253S与配锁部21S脱离锁定。

第七实施例的其他特征可参见第五实施例。
以下将描述本申请的第八实施例。
参见图37和图38，第八实施例的扣具100S与第七实施例的扣具100S具有类似的第二扣件1S和第一扣件2S的外形。释锁操作件3S上可设有盖体34S，从而封闭通孔31S。盖体34S可以是可拆卸的。
参见图39到图41，扣具100S可具有一个锁定部125S。锁定部125S可具有一个锁头1253S和一个弹臂1254S。锁头1253S、弹臂1254S和外框架121S可一体形成，但本申请不限于此。在一些实施例中，锁头1253S、弹臂1254S和外框架121S也可以是单独的结构，并且锁头1253S可通过弹臂1254S连接至外框架121S。锁头1253S可设置在第一磁体容置部122S沿第二方向Y的远离所述释锁操作件3S的一侧。换言之，锁头1253S可位于配锁部21S沿第二方向Y远离释锁操作件3S的一侧。锁头可以具有半圆弧形结构，但不以此为限。弹臂1254S可位于锁头1253S的远离释锁操作件3S的一侧。弹臂1254S可形成为折线形状，从而沿第二方向Y提供弹力。释锁操作件3S可具有释锁顶推部32S。释锁顶推部32S可以是笔直的且逐渐变细，但不以此为限。释锁操作件3S可具有两个释锁顶推部32S，但本申请不以此为限。
第二扣件本体12S可包括第一连接臂部1231S(也就是说，在第八实施例中，连接臂123S仅包括第一连接臂部1231S而不包括第二连接臂部1232S)。第一连接臂部1231S可设置在第二扣件本体12S的第一侧(例如，沿第二方向Y靠近释锁操作件3S的一侧)。弹臂1254S可设置在相对的第二侧(例如，沿第二方向Y远离释锁操作件3S的一侧)。在一些实施例中，第一连接臂部1231S和弹臂1254S的位置和互换，即，弹臂1254S可设置在靠近释锁操作件3S的一侧，释锁顶推部32S可以对锁头1253S施加拉力。第一连接臂部1231S可沿第二方向Y延伸，并且第一连接臂部1231S的两端可连接到外框架121S和第一磁体容置部122S。
参见图39，第二扣件本体12S可具有避让凹部1218S。避让凹部1218S可形成在外框架121S的底部，以允许释锁顶推部32S穿过第二扣件本体12S。避让凹部1218S的数量可与释锁顶推部32S的数量相同。在其他实施例中，避让凹部1218S的数量可与释锁顶推部32S的数量不同。
第一磁体容置部122S和第二磁体容置部22S可以是圆形。相应地，第一磁体5S和第二磁体6S可以是圆形。
参见图41，第二扣件壳体11S可包括饰盖113S。饰盖113S可覆盖第二扣件壳体11S的一部分，从而起到装饰作用。饰盖113S大体可以是矩形平板，且在一侧形成为弧形，但本申请不以此为限。
参见图39到图41，当第一扣件2S与第二扣件1S对插配合时，配锁部21S的配锁斜面2111S推动锁头1253S沿第二方向Y远离配锁部21S。然后，第一扣件2S与第二扣件1S可进一步靠近彼此并互相锁定。当第一扣件2S与第二扣件1S彼此锁定时，锁头1253S的一部分位于锁定槽212S内使得锁头1253S被配锁部21S锁定。当锁头1253S与配锁部21S解除锁定时，释锁操作件3S被按压，使得两个释锁顶推部32S沿第二方向Y推动锁头1253S，以使锁头1253S在第一方向X和/或第二方向Y上远离配锁部21S，使得锁头1253S不再与配锁部21S卡合，从而允许配锁部21S离开第二扣件1S。
第八实施例的其他特征可参见第五实施例和第七实施例。
以下将描述本申请的第九实施例。
参见图42到图46，扣具100T可包括第一扣件1T、第二扣件2T和释锁操作件3T。扣具100T还可包括两个弹性件6T。第二扣件2T内可设有锁定部4T，第一扣件1T可包括对插配锁部5T。对插配锁部5T可用于与锁定部4T配合。第一扣件1T与第二扣件2T沿对插方向(如图49中箭头P所指方向，也可称为“第一方向”)对插，以使锁定部4T沿扣具100T的侧面方向(如图47中箭头M1和M2所指的方向，也可称为“第二方向”)与对插配锁部5T锁定。对插方向可以与侧面方向交错。优选地，对插方向可以与侧面方向垂直。释锁操作件3T可设置于第二扣件2T并与锁定部4T连动。具体地，释锁操作件3T可部分地设置在第二扣件2T内。释锁操作件3T沿侧面方向的运动可顶推锁定部4T沿侧面方向运动，以使锁定部4T与对插配锁部5T解锁。锁定部4T可以与第二扣件2T独立地形成，而并非一体形成。
在此实施例中，第一扣件1T可为第一扣件，第二扣件2T可为母扣，当然，根据实际情况需要，在另一实施例中，第一扣件可为母扣，第二扣件可为公扣，故不以此为限。
参见图42和图47，释锁操作件3T内嵌于第二扣件2T并与锁定部4T连动设置。释锁操作件3T还可部分地外露于第二扣件2T的侧壁，并可相对于第二扣件2T沿所述侧面方向移动。如图47到图50所示，释锁操作件3T可在沿所述侧面方向移动的过程中，驱使锁定部4T沿第二扣件2T的所述侧面方向做远离对插配锁部5T的运动，从而使锁定部4T与对插配锁部5T释锁。释锁操作件3T的移动方向与释锁操作件3T驱使锁定部4T的释锁方向相同，以使得操作者作用在释锁操作件3T上的力能够沿着其移动方向全部传递至锁定部4T，且锁定部4T受到释锁操作件3T的全部作用力而释锁。这避免了操作者所施加的力在所述侧面方向之外的其他方向上分散，从而使得用户释锁操作更加省力，释锁更便捷。
参见图42和图43，对插配锁部5T位于第一扣件1T的正面处，第二扣件2T开设有供对插配锁部5T插入的对插孔21T。第一扣件1T与第二扣件2T的对插方向(如图49中箭头P所指方向)与释锁操作件3T的移动方向(如图47中箭头M1、M2所指方向)相交错。优选地，第一扣件1T与第二扣件2T的对插方向与释锁操作件3T的移动方向互相垂直。这使得在制造过程中可减小扣具100T在对插方向上的厚度，从而提高扣具100T内部的空间利用率。
参见图42和图43，第一扣件1T的上下两端可分别具有翼部12T。翼部12T可便于将第一扣件1T车缝在座部上。在其他实施例中，第一扣件1T的上端或下端可具有翼部12T。可选地，第一扣件1T上可形成有与连接带(未示出)相连的孔。
参见图42到图44，第二扣件2T可包括第一壳体201T、第二壳体202T和枢轴203T。第一壳体201T和第二壳体202T可彼此结合以包围一定的内部空间。枢轴203T可设置在第一壳体201T的孔内，以便于与连接带(未示出)相连。参见图44，锁定部4T可具有弹性结构。释锁操作件3T驱使锁定部4T沿第二扣件2T的所述侧面方向做远离对插配锁部5T的运动，以使弹性结构发生弹性形变，并且锁定部4T与对插配锁部5T释锁。
具体地，参见图44，锁定部4T包括位于对插配锁部5T的一侧的第一锁定部4aT及位于对插配锁部5T相对的另一侧的第二锁定部4bT。第一锁定部4aT和第二锁定部4bT可沿所述侧面方向抱合对插配锁部5T。释锁操作件3T可包括与第一锁定部4aT同侧布置的第一释锁操作件3aT及与第二锁定部4bT同侧布置的第二释锁操作件3bT。第一释锁操作件3aT抵靠第二锁定部4bT。第二释锁操作件3bT抵靠第一锁定部4aT。通过第一释锁操作件3aT驱使第二锁定部4bT远离对插配锁部5T及第二释锁操作件3bT驱使第一锁定部4aT远离对插配锁部5T，从而使第一锁定部4aT及第二锁定部4bT脱离与对插配锁部5T的锁合。因此，借助第一释锁操作件3aT、第二释锁操作件3bT、第一锁定部4aT及第二锁定部4bT之间的相互配合，使得锁合与释锁两个过程更加可靠。
在其他实施例中，释锁操作件和锁定部可分别为一个、三个或四个，等等。
参见图44，第一锁定部4aT包括用于与对插配锁部5T锁合的第一锁头42aT和设置在第一锁头42aT与第二扣件2T之间的第一复位件44aT。第一复位件44aT可以是螺旋弹簧，但本申请不以此为限。第一复位件44aT恒具有驱使第一锁头42aT沿所述侧面方向与对插配锁部5T相互锁合的趋势。第二释锁操作件3bT用于驱使第一复位件44aT做远离对插配锁部5T的弹性形变，以使第一锁头42aT与对插配锁部5T释锁。
第二锁定部4bT包括用于与对插配锁部5T锁合的第二锁头42bT和设置在第二锁头42bT与第二扣件2T之间的第二复位件44bT。第二复位件44bT可以是螺旋弹簧，但本申请不以此为限。第二复位件44bT恒具有驱使第二锁头42bT沿所述侧面方向与对插配锁部5T相互锁合的趋势。第一释锁操作件3aT用于驱使第二复位件44bT做远离对插配锁部5T的弹性形变，以使第二锁头42bT与对插配锁部5T释锁。
参见图44和图47，所述顶推部沿所述第二方向延伸且抵接所述锁头。第一释锁操作件3aT沿所述侧面方向凸伸有第一顶推部31aT，第二锁头42bT上设有与第一顶推部31aT连动设置的第二配顶部43bT，第一释锁操作件3aT在沿所述侧面方向移动的过程中通过第一顶推部31aT对第二配顶部43bT的顶推而使第二锁头42bT抵抗第二复位件44bT的复位力而远离对插配锁部5T，从而使第二锁头42bT与对插配锁部5T释锁。第二释锁操作件3bT沿所述侧面方向凸伸有第二顶推部31bT，第一锁头42aT上设有与第二顶推部31bT连动设置的第一配顶部43aT，第二释锁操作件3bT在沿所述侧面方向移动的过程中通过第二顶推部31bT对第一配顶部43aT的顶推而使第一锁头42aT抵抗第一复位件44aT的复位力而远离对插配锁部5T，从而使第一锁头42aT与对插配锁部5T释锁。第一配顶部43aT可位于第一锁头42aT的上端(靠近第一释锁操作件3aT的一端)。第二配顶部43bT可位于第二锁头42bT的上端(靠近第二释锁操作件3bT的一端)。
可选地，第一配顶部43aT可沿所述侧面方向与第二顶推部31bT相对齐，第二配顶部43bT可沿所述侧面方向与第一顶推部31aT相对齐，从而使得释锁操作件3T的顶推更加精确，并且释锁操作更加省力。
第一顶推部31aT和第二顶推部31bT可沿对插方向P至少部分地重叠，从而节省第二扣件内的空间。具体地，第一配顶部43aT在扣具100T的对插方向P(也称为“高度方向”)上与第二配顶部43bT呈一高一低的布置，第一顶推部31aT在扣具100T对插方向P上与第二顶推部31bT呈一高一低的布置。这样，第一顶推部31aT及第二顶推部31bT的顶推运动分别位于不同的高度，从而使第一顶推部31aT及第二顶推部31bT沿所述侧面方向的移动不会彼此干涉，故保证了释锁的可靠性。
举例而言，第二顶推部31bT与第一配顶部43aT的高度相同，第一顶推部31aT与第二配顶部43bT的高度相同，并且第二顶推部31bT与第一配顶部43aT的高度高于第一顶推部31aT与第二配顶部43bT的高度，但本申请不以此为限。
在一个实施例中，第一配顶部43aT还沿所述侧面方向与第二配顶部43bT相错开，第一顶推部31aT还沿所述侧面方向与第二顶推部31bT相错开，从而减小了第一配顶部43aT及第二配顶部43bT在高度方向的空间占用。将第一配顶部43aT及第二配顶部43bT沿所述侧面方向错开，更有利于扣具100T的空间布置。
在一个实施例中，第一顶推部31aT及第二配顶部43bT在垂直所述对插方向与所述侧面方向的凸伸方向(如图47中箭头Q所指方向，也可称为“第三方向”)上位置超前于第二顶推部31bT及第一配顶部43aT在所述凸伸方向上的位置，但不以此为限。也就是说，如图47所示，第一顶推部31aT及第二配顶部43bT比第二顶推部31bT及第一配顶部43aT更靠上方。
参见图44、图49和图50，对插配锁部5T具有顶推结构51T及配锁结构52T。顶推结构51T在第一扣件1T与第二扣件2T对插过程中顶推第一锁头42aT及第二锁头42bT以引起第一复位件44aT和第二复位件44bT被压缩，然后使第一锁头42aT及第二锁头42bT移动至与配锁结构52T相锁合的位置。第一释锁操作件3aT和第二释锁操作件3bT可被按压以驱使第一锁头42aT及第二锁头42bT远离配锁结构52T而释锁。
可选地，顶推结构51T的端部具有倾斜于所述对插方向的第一倾斜结构511T，并且第一锁头42aT及第二锁头42bT可分别具有与第一倾斜结构511T匹配的第二倾斜结构421T。在第一扣件1T与第二扣件2T对插过程中，借助第一倾斜结构511T对第二倾斜结构421T的顶推而使顶推结构51T越过锁头并移动至配锁结构52T与锁头锁合的位置。举例而言，配锁结构52T为环形凹槽，锁头用于卡入所述环形凹槽。
参见图44、图47和图48，扣具100T可包括弹性件6T。弹性件6T可设于释锁操作件3T与第二扣件2T之间，弹性件6T恒具有驱使释锁操作件3T沿远离锁定部4T的方向移动的趋势，以通过弹性件6T的弹性使得释放释锁操作件3T后能让释锁操作件3T复位。具体地，第二扣件2T设有抵接弹性件6T的第一挡板24T和第二挡板26T。第一挡板24T抵接弹性件6T的一端，而第二挡板26T抵接弹性件6T的上侧。第一挡板24T和第二挡板26T可一体形成且彼此交错。优选地，第一挡板24T和第二挡板26T可呈90°。具体地，扣具100T可包括两个弹性件6T。两个弹性件6T的每一个均抵接一个第一挡板24T和一个第二挡板26T。两个第一挡板24T位于两个弹性件6T之间。
释锁操作件3T的第一释锁操作件3aT与第二释锁操作件3bT分别设有限位凸起33T，第二扣件2T具有与限位凸起33T抵挡配合的两个限位挡块25T，第二扣件2T在限位挡块25T与限位凸起33T相抵挡的作用下阻挡释锁操作件3T的第一释锁操作件3aT与第二释锁操作件3bT从第二扣件2T处滑落。
参见图44到图47，锁定部4T与第二扣件2T卡合连接。较优的是，锁定部4T与第二扣件2T呈可拆卸的卡合连接，故锁定部4T或者第二扣件2T中任一者损坏即可更换，另外，使得本申请的扣具100T的制造工艺更为简单。
第二扣件2T内可具有不同方向的定位杆27T。定位杆27T可抵接锁定部4T从而避免锁定部4T在第二扣件2T内不期望地移动。锁定部4T可包括定位叉46T。定位叉46T可以与一个沿凸伸方向Q延伸的定位杆27T配合以共同限位第二磁性结构8T。可选地，定位叉46T也可用来与其左右两侧的定位杆27T共同限位锁定部4T。定位叉46T的左右两侧(图47或图48中的左右两侧)的定位杆27T可设置第二扣件2T的壳体(第一壳体201T或第二壳体202T)上，且位于锁定部4T远离第一配顶部43aT和第二配顶部43bT的一侧。定位叉46T的左右两侧的定位杆27T主要用来限位锁定部4T的运动。当操作释锁操作件3T释锁时，释锁操作件3T与定位叉46T的左右两侧的定位杆27T配合以使锁定部4T的第一端(靠近第一配顶部43aT或第二配顶部43bT的一端)能够稳定地移动张开，并挤压弹性件44T。当释放释锁操作件3T时，弹性件44T可以提供回复力，使锁定部4T稳定地回复到与对插配锁部5T卡合的位置。锁定部4T上还设置有定位部45T。具体地，第一锁头42aT和第二锁头42bT上均设置有定位部45T。弹性件44T的一端抵接定位部45T，另一端抵接第二扣件2T的第一壳体201T。定位部45T可位于第一锁头42aT和/或第二锁头42bT的中间位置。
参见图44、图49和图50，本申请的扣具100T还包括第一磁性结构7T及第二磁性结构8T。第一磁性结构7T设于第一扣件1T上，第二磁性结构8T设于第二扣件2T上。第一磁性结构7T与第二磁性结构8T在第一扣件1T与第二扣件2T对插过程中相互磁性吸附。这使得第一扣件1T与第二扣件2T的扣合更快速，并且即使锁定部4T与对插配锁部5T之间脱离锁合，第一扣件1T与第二扣件2T也因第一磁性结构7T及第二磁性结构8T相互磁性吸附而保持接合状态，从而预防意外释锁，并且保证本申请扣具100T的安全性。
在另一实施例中，第一磁性结构7T与第二磁性结构8T可在第一扣件1T与第二扣件2T的对插过程中相互磁性排斥，以使得释锁更加便捷。
第一扣件1T开设有第一嵌设腔11T，第二扣件2T开设有第二嵌设腔23T。第一磁性结构7T嵌设于第一嵌设腔11T内，第二磁性结构8T嵌设于第二嵌设腔23T内。第一嵌设腔11T沿对插方向与第二嵌设腔23T相对齐，以使得第一磁性结构7T及第二磁性结构8T之间的吸附作用力更强，但本申请不限于此。具体地，第二嵌设腔23T沿所述对插方向正对第一锁头42aT与第二锁头42bT之间的空间，以使得本申请的扣具100T体积小巧且空间利用率高。覆盖件9T可覆盖第一嵌设腔11T，从而将第一磁性结构7T与外界隔绝。
参见图47到图50，现对本申请的扣具100T的工作原理进行说明。释锁操作时，用户克服两个弹性件6T的弹力而同时按下第一释锁操作件3aT及第二释锁操作件3bT。第一释锁操作件3aT的第一顶推部31aT顶推第二配顶部43bT，第二释锁操作件3bT的第二顶推部31bT顶推第一配顶部43aT，从而带动第一锁头42aT及第二锁头42bT克服第一复位件44aT和第二复位件44bT的复位力而分别远离对插配锁部5T运动。此时，扣具100T处于可释锁状态。在保持按下第一释锁操作件3aT及第二释锁操作件3bT的状态下，可将第一扣件1T与第二扣件2T相互拔离，以使扣具100T完全释锁。在松开第一释锁操作件3aT及第二释锁操作件3bT后，弹性件6T驱使第一释锁操作件3aT及第二释锁操作件3bT复位。第一复位件44aT和第二复位件44bT分别驱使第一锁头42aT及第二锁头42bT复位。当需要锁定第一扣件1T与第二扣件2T时，将对插配锁部5T对准对插孔21T并插入。顶推结构51T同时顶推第一锁头42aT及第二锁头42bT向两侧远离对插配锁部5T，以使第一锁头42aT及第二锁头42bT分别移动至与配锁结构52T相锁合的位置。
在第九实施例中虽然描述了第一释锁操作件3aT和第二释锁操作件3bT，可以理解，在其他实施例中，扣具100T可仅具有第一释锁操作件3aT或第二释锁操作件3bT。同样地，在其他实施例中，扣具100T可仅具有一个顶推部、一个锁定部、一个配顶部或一个复位件。
以下将描述本申请的第十实施例。
参见图51和图52，锁定部4T可包括第一锁头42aT、第二锁头42bT、第一弹臂41aT和第二弹臂41bT。第一锁头42aT与第一弹臂41aT可一体形成。第二锁头42bT与第二弹臂41bT可一体形成。第一弹臂41aT和第二弹臂41bT可分别替代第一复位件44aT和第二复位件44bT，以对第一锁头42aT和第二锁头42bT提供弹性复位力，使得第一锁头42aT和第二锁头42bT趋于与对插配锁部5T互相锁定。第一弹臂41aT可形成在第一锁头42aT的远离弹性件6T的一端(即，图51中的下端)。第二弹臂41bT可形成在第二锁头42bT的远离弹性件6T的一端(即，图51中的下端)。第一弹臂41aT可平行于第二弹臂41bT，但本申请不以此为限。
锁定部4T还可包括卡合支撑架44T。第一弹臂41aT远离第一锁头42aT的一端以及第二弹臂41bT远离第二锁头42bT的一端可与卡合支撑架44T一体形成。卡合支撑架44T可包括连接部分442T和延伸部分443T。连接部分442T可基本垂直于第一弹臂41aT或第二弹臂41bT。换言之，连接部分442T可沿侧面方向(如图47中箭头M1和M2所指的方向)延伸。延伸部分443T可在第一弹臂41aT与第二弹臂41bT之间，从连接部分442T伸出。延伸部分443T可形成为类似“T”形。延伸部分443T可限制第一弹臂41aT和第二弹臂41bT向内的变形程度，以避免第一弹臂41aT和第二弹臂41bT被损坏。
锁定部4T还可包括第一固定部411aT和第二固定部411bT。第一固定部411aT和第二固定部411bT可位于连接部分442T的两端，且呈圆环形。第一固定部411aT和第二固定部411bT可起到固定作用，以将锁定部4T稳定地固定于第二扣件2T。
第一锁头42aT上设有与第二顶推部31bT连动设置的第一配顶部43aT。第一配顶部43aT在第一锁头42aT上沿对插方向(如图49中箭头P所指方向)延伸。第二释锁操作件3bT在沿所述侧面方向移动的过程中通过第二顶推部31bT对第一配顶部43aT的顶推而使第一弹臂41aT弹性变形并且使第一锁头42aT远离对插配锁部5T，从而使第一锁头42aT与对插配锁部5T释锁。第二锁头42aT上设有与第一顶推部31aT连动设置的第二配顶部43bT。第二配顶部43bT在第二锁头42aT上沿对插方向(如图49中箭头P所指方向)延伸。第一释锁操作件3aT在沿所述侧面方向移动的过程中通过第一顶推部31aT对第二配顶部43bT的顶推而使第二弹臂41bT弹性变形并且使第二锁头42bT远离对插配锁部5T，从而使第二锁头42bT与对插配锁部5T释锁。
参见图52，第二配顶部43bT可位于第二锁头42bT沿第三方向Q的中间位置。第一配顶部43aT在第三方向Q上可位于第二配顶部43bT与第一弹臂41aT之间。也就是说，如图52所示，第一配顶部43aT到第一锁头42aT的上端的距离大于第一配顶部43aT到第一锁头42aT的下端的距离。
第一配顶部43aT可包括第一部段431aT和第二部段432aT。第一配顶部43aT的第一部段431aT可垂直于第一配顶部43aT的第二部段431bT，使得第一配顶部43aT形成为“L”形。第二配顶部43bT可包括第一部段431bT、第二部段432bT和第三部段433bT。第二配顶部43bT的第一部段431bT和第三部段433bT可位于第二配顶部43bT的第二部段432bT的两端。在其他实施例中，第一配顶部43aT和第二顶配部43bT可具有相同的形状，并且均具有两个或三个部段。
可选地，第一配顶部43aT可位于第一锁头42aT在凸伸方向(如图47中箭头Q所指方向)的靠下部分(靠近第一弹臂41aT的部分)，第二配顶部43bT可位于第二锁头42bT在凸伸方向的中间部分。
可选地，第一配顶部43aT可沿所述侧面方向与第二顶推部31bT相对齐，第二配顶部43bT可沿所述侧面方向与第一顶推部31aT相对齐，从而使得释锁操作件3T的顶推更加精确，并且释锁操作更加省力。
第一顶推部31aT和第二顶推部31bT可沿对插方向P至少部分地重叠，从而节省第二扣件内的空间。具体地，第一配顶部43aT在扣具100T的对插方向P(也称为“高度方向”)上与第二配顶部43bT呈一高一低的布置，第一顶推部31aT在扣具100T对插方向P上与第二顶推部31bT呈一高一低的布置。这样，第一顶推部31aT及第二顶推部31bT的顶推运动分别位于不同的高度，从而使第一顶推部31aT及第二顶推部31bT沿所述侧面方向的移动不会彼此干涉，故保证了释锁的可靠性。在其他未示出的实施例中，第一顶推部31aT和第二顶推部31bT可沿对插方向P不重叠，使得第二扣件2T的厚度更薄。
第一配顶部43aT的第一部段431aT可限位第一顶推部31aT沿所述侧面方向的移动，从而使第一顶推部31aT的移动更稳定。第二配顶部43bT的第一部段431bT可限位第二顶推部31bT沿所述侧面方向的移动，从而使第二顶推部31bT的移动更稳定。第一配顶部43aT的第一部段431aT可提高第一配顶部43aT的结构强度。第二配顶部43bT的第一部段431bT和第三部段433bT可提高第二配顶部43bT的结构强度。第一配顶部43aT和第二配顶部43bT可位于锁定部4T的同侧，即，在对插方向P上远离对插配锁部5T的一侧。这样，第一配顶部43aT和第二配顶部43bT可以不影响第一扣件1T和第二扣件2T的配合，并且第二扣件2T的厚度可以更薄。
以下将描述本申请的第十一实施例。
参见图53，本申请的扣具100F可包括第一扣件1F和第二扣件2F。第一扣件1F和第二扣件2F可彼此对插配合。第一扣件1F和第二扣件2F可彼此锁定或解锁。需指出，在本申请中，“第一扣件”和“第二扣件”仅用于区分两个扣件，而并非具有特定的含义，“第一扣件”和“第二扣件”的名称也可互换。
第一扣件1F可包括本体11F。本体11F可具有对称的形状，但本申请不以此为限。本体11F上可具有配锁部12F。配锁部12F可居中地设置在本体11F上，并且可从本体11F突出。配锁部12F可具有柱形，但本申请不以此为限。配锁部12F的内部可形成空腔(参见图57A)，第一磁体5F可位于配锁部12F的内部。密封件14F可将第一磁体5F密封在配锁部12F的内部。本体11F的两侧分别可形成带孔13F。带孔13F可与织带连接以约束第一扣件1F相对于织带的位置。配锁部12F上可形成有顶推斜面121F和锁定槽122F。顶推斜面121F可位于配锁部12F的顶端的外周。锁定槽122F可位于顶推斜面121F与本体11F之间，且环绕配锁部12F一圈。第一扣件1F可形成为大体矩形的形状，但本申请不以此为限。
第二扣件2F可包括壳体20F和释锁组件23F。壳体20F可包括底座21F和盖件22F。释锁组件23F可设置在底座21F和盖件22F之间。第二扣件2F中可设有第二磁体6F。底座21F和盖件22F可包围一定的空间以形成容纳释锁组件23F的腔室。该腔室可具有开口以允许释锁组件23F的部分地伸出。第二扣件2F可形成为大体矩形的形状，但本申请不以此为限。
参见图54，释锁组件23F可包括按压部231F、弹性结构232F和卡合头234F。按压部231F可至少部分地伸出由底座21F和盖件22F包围的腔室，从而可在所述腔室的外部按压按压部231F。按压部231F可相对于底座21F和盖件22F沿横向X滑动。弹性结构232F的一端可连接到按压部231F。弹性结构232F的另一端可连接到卡合头234F。
参见图54和图55，弹性结构232F可以是弯曲的线条形结构。弹性结构232F的弯曲都是在扣具100F的侧向上。在本申请中，“竖直方向”是第一扣件1F和第二扣件2F彼此对插配合的方向，“侧向”是指垂直于竖直方向Z的平面上的方向，或者是由横向X和纵向Y构成的平面内的方向。弹性结构232F可包括第一区段2321F和第二区段2323F。盖件22F可包括凸柱221F。凸柱221F可形成为圆柱形，但本申请不以此为限。在其他实施例中，凸柱221F可形成为正方形、长方形或其他形状的突起。凸柱221F可设置在壳体20F上。具体地，凸柱221F可设置在盖件22F上，并且从盖件22F朝向底座21F沿竖直方向Z延伸。在另一实施例中，凸柱221F可设置在底座21F上。凸柱221F可接触底座21F，但本申请不以此为限。凸柱221F在竖直方向Z上的尺寸可大于第一区段2321F在竖直方Z向上的尺寸。弹性结构232F可抵接凸柱221F。具体地，如图55所示，凸柱221F接触弹性结构232F的内侧。第一区段2321F在凸柱221F靠近按压部231F的一侧，而第二区段2323F在凸柱221F远离按压部231F的一侧。当从第二扣件2F的外部向内按压按压部231F时，第一区段2321F随着按压部231F一起向内运动，并且发生弹性变形。由于凸柱221F抵接弹性结构232F，第二区段2323F向外运动(朝向第二扣件2F的外周运动)。具体而言，在按压部231F被致动时，第一区段2321F的形变方向与第二区段2323F的运动方向相反。
可选地，弹性结构232F可具有凸出部2322F。凸出部2322F的曲率可与弹性结构232F的其他部分的曲率不同(例如，凸出部2322F的曲率大于弹性结构232F的其他部分的曲率)，且向所述第二扣件的外周突出。也就是说，凸出部2322F可以通过弯折弹性结构232F而形成。凸出部2322F可形成在第二区段2323F，且靠近弹性结构232F接触凸柱221F的部分，但本申请不以此为限。
参见图54和图55，卡合头234F可形成为片状。卡合头234F可连接到弹性结构232F远离按压部231F的一端。也就是说，卡合头234F可连接到第二区段2323F的一端。底座21F可包括接纳孔211F。当未致动按压部231F时，卡合头234F可部分地位于接纳孔211F内。当致动按压部231F时，弹性结构232F可变形，进而引起卡合头234F远离接纳孔211F移动。
参见图53和图57A，配锁部12F可插入接纳孔211F以与卡合头234F锁定。具体地，卡合头234F可沿扣具100F的侧向插入配锁部12F的锁定槽122F，从而阻止配锁部12F沿竖直方向Z离开接纳孔211F。
可选地，释锁组件23F包括卡合头连接部233F。卡合头连接部233F具有弯曲的形状并且将卡合头234F与弹性结构232F连接。卡合头连接部233F可具有一定的弹性。卡合头连接部233F和卡合头234F的延伸方向可垂直于按压部231F的运动方向，但本申请不以此为限。因此，第一区段2321F和第二区段2323F在壳体20F的外侧沿周向延伸，而卡合头234F在壳体20F的内侧沿周向延伸。
如图54和图55所示，释锁组件23F可包括两个按压部231F、四个弹性结构232F和四个卡合头234F。两个按压部231F分别位于底座21F的两侧。每个按压部231F与四个弹性结构232F中的两个弹性结构232F连接。每个弹性结构232F连接四个卡合头234F中的一个卡合头234F(例如，经由一个卡合头连接部233F连接)。
在一个实施例中，释锁组件23F可包括一个按压部231F、两个弹性结构232F和两个卡合头234F。一个按压部231F位于底座21F的一侧。按压部231F与两个弹性结构232F连接。每个弹性结构232F连接两个卡合头234F中的一个卡合头234F。
在一个实施例中，释锁组件23F可包括两个按压部231F、两个弹性结构232F和两个卡合头234F。两个按压部231F分别位于底座21F的两侧。每个按压部231F与两个弹性结构232F中的一个弹性结构232F连接。每个弹性结构232F连接两个卡合头234F中的一个卡合头234F。
参见图54，第二扣件2F可具有磁体容纳部216F。第二磁体6F可固定在磁体容纳部216F中。磁体容纳部216F和第二磁体6F均可以是圆形的，但本申请不以此为限。底座21F可具有带孔215F。带孔215F可与织带连接以限制第二扣件2F相对于织带的位置。
底座21F可包括纵向导向肋212F。纵向导向肋212F可以是笔直的，并且沿垂直于按压部231F的移动方向的方向(即，纵向Y)延伸。磁体容纳部216F的两侧均可具有纵向导向肋212F。纵向导向肋212F可连接磁体容纳部216F和底座21F的外周。纵向导向肋212F可从磁体容纳部216F到底座21F的外周逐渐变细，但本申请不以此为限。磁体容纳部216F两侧的纵向导向肋212F处于一条直线上。纵向导向肋212F可居中地设置在底座21F上。弹性结构232F的远离按压部231F的一端可抵接纵向导向肋212F。纵向导向肋212F可包括第一部分2121F和第二部分2122F。第一部分2121F的厚度可大于第二部分2122F的厚度，但本申请不以此为限。
在一个实施例中，底座21F可仅包括一个纵向导向肋212F。也就是说，仅磁体容纳部216F的一侧具有纵向导向肋212F。
底座21F还可包括横向导向肋213F和导向块214F。横向导向肋213F可以是笔直的。磁体容纳部216F的两侧均可具有横向导向肋213F。横向导向肋213F可连接磁体容纳部216F。导向块214F可形成为圆柱形的突起，但本申请不以此为限。在其他实施例中，导向块214F可形成为正方形、长方形或其他形状的突起。按压部231F的一侧(朝向磁体容纳部216F的一侧)可具有导向臂235F。导向臂235F可位于横向导向肋213F和导向块214F之间，使得横向导向肋213F和导向块214F可限制导向臂235F的运动方向。换言之，横向导向肋213F与导向块214F之间的距离基本等于导向臂235F的宽度。横向导向肋213F可垂直于纵向导向肋212F。换言之，横向导向肋213F的延伸方向与按压部231F的运动方向相同。横向导向肋213F可包括第三部分2131F和第四部分2132F。第三部分2131F的厚度可大于第四部分2132F的厚度，但本申请不以此为限。
在本实施例中，每个按压部231F可具有彼此平行的两个导向臂235F。一个横向导向肋213F可位于两个导向臂235F之间。底座21F可包括两个导向块214F。两个导向块214F位于两个导向臂235F的外侧。
在一个实施例中，底座21F可仅包括一个横向导向肋213F。也就是说，仅磁体容纳部216F的一侧具有横向导向肋213F。
在一个实施例中，每个按压部231F可具有一个导向臂235F。底座21F可包括一个导向块214F。
参见图55和图56，盖件22F可具有限位肋222F。限位肋222F可从盖件22F向底座21F突出。限位肋222F可具有直线的形状。可选地，限位肋222F可具有弯曲的形状、“T”形，等等。限位肋222F可限制弹性结构232F和卡合头235F在竖直方向Z的不期望的移动。在本实施例中，盖件22F可具有四个限位肋222F。在其他实施例中，盖件22F可具有一个、两个、六个、八个或其他数量的限位肋222F。
以下将描述扣具100F的操作。
参见图55到图57A，当第一扣件1F与第二扣件2F锁定时，第一扣件1F沿竖直方向Z与第二扣件2F结合。第一扣件1F的配锁部12F进入第二扣件2F的接纳孔211F。配锁部12F上的顶推斜面121F推动卡合头234F沿侧向往离开接纳孔211F的方向移动，以允许配锁部12F继续进入第二扣件2F。在此过程中，卡合头234F的侧向移动引起卡合头连接部233F变形。当配锁部12F移动到锁定槽122F对准卡合头234F时，卡合头连接部233F恢复到未变形的状态，并将卡合头234F推动到锁定槽122F内，从而使卡合头234F与锁定槽122F卡合。此时，第一扣件1F与第二扣件2F完成锁定。
当欲使第一扣件1F与第二扣件2F解除锁定时，按压两侧的按压部231F，以使两个按压部231F朝向接纳孔211F移动。两个按压部231F朝向接纳孔211F的移动带动弹性结构232F的第一区段2321F朝向接纳孔211F移动。由于弹性结构抵接凸柱221F，第一区段2321F朝向接纳孔211F的移动引起弹性结构232F的第二区段2323F沿远离接纳孔211F的方向移动。连接到第二区段2323F的卡合头234F随着第二区段2323F一起远离接纳孔211F移动，从而使卡合头234F离开锁定槽122F。此时，配锁部12F未被卡合头234F锁定，从而可沿与卡合头234F插入接纳孔211F的方向的相反方向移动到第二扣件2F之外，从而实现第一扣件1F与第二扣件2F的分开。
在其他实施例中，例如，卡合头连接部233F不具有弹性。在第一扣件1F的配锁部12F进入第二扣件2F的接纳孔211F，且配锁部12F上的顶推斜面121F推动卡合头234F沿侧向往离开接纳孔211F的方向移动过程中，卡合头234F的侧向移动引起弹性结构232F(例如，第二区段2323F和凸出部2322F)变形。
以下将描述本申请的第十二实施例。第十二实施例与第十一实施例相同的部分将省略以避免重复。
参见图57B，凸柱221F可包括凸柱本体2211F和凸柱限位部2212F。凸柱本体2211F可形成为圆柱形，但本申请不以此为限。在其他实施例中，凸柱本体2211F可形成为正方形、长方形或其他形状的突起。凸柱本体2211F可设置在壳体20F上。具体地，凸柱本体2211F可设置在盖件22F上，并且从盖件22F朝向底座21F沿竖直方向Z延伸。在另一实施例中，凸柱本体2211F可设置在底座21F上。
凸柱限位部2212F从凸柱本体2211F的一端沿侧向延伸，用于限制弹性结构232F和卡合头235F在竖直方向Z的不期望的移动。凸柱本体2211F在竖直方向Z上的尺寸可大于或等于第一区段2321F和凸柱限位部2212F在竖直方Z向上的尺寸之和。由于弹性结构232F可在不同位置分别被凸柱限位部2212F和限位肋222F限位，弹性结构232F和卡合头235F在竖直方向Z上会具有更好的稳定性。
第十二实施例的其他内容可参见第十一实施例。
以下将描述本申请的第十三实施例。第十三实施例与第十一实施例相同的部分将省略以避免重复。
参见图58，扣具100F可包括第一扣件1F和第二扣件2F。第一扣件1F和第二扣件2F可彼此对插配合。第一扣件1F和第二扣件2F可彼此锁定或解锁。第二扣件2F可包括底座21F、盖件22F以及设置在底座21F和盖件22F之间的释锁组件23F。本实施例的盖件22F可不包括凸柱221F。
参见图59到图61，释锁组件23F可包括按压部231F、弹性结构232F和卡合头234F。弹性结构232F的一端可连接到按压部231F。弹性结构232F的另一端(末端)可连接到卡合头234F。释锁组件23F包括卡合头连接部233F。卡合头连接部233F具有弯曲的形状并且将卡合头234F与弹性结构232F连接。卡合头连接部233F和卡合头234F的延伸方向可垂直于按压部231F的运动方向。
释锁组件23F还可包括延伸部236F。延伸部236F可形成为直线形杆件且连接到弹性结构232F的远离按压部231F的一端。延伸部236F与卡合头234F和卡合头连接部233F相邻。卡合头234F可位于延伸部236F与按压部231F之间。
底座21F可包括纵向导向肋212F。纵向导向肋212F可以是笔直的，并且沿垂直于按压部231F的移动方向的方向延伸。延伸部236F可以与纵向导向肋212F平行且接触纵向导向肋212F。
延伸部236F的数量可与弹性结构232F的数量相同。在本实施例中，释锁组件23F可包括四个延伸部236F。
在其他实施例中，释锁组件23F可包括一个、两个或其他数量的延伸部236F。
以下将描述扣具100F的操作。
参见图60到图62，当第一扣件1F与第二扣件2F锁定时，第一扣件1F从下方与第二扣件2F结合。第一扣件1F的配锁部12F进入第二扣件2F的接纳孔211F。配锁部12F上的顶推斜面121F推动卡合头234F沿侧向移动离开接纳孔211F，以允许配锁部12F继续进入第二扣件2F。在此过程中，卡合头234F的侧向移动引起卡合头连接部233F变形。当配锁部12F移动到锁定槽122F对准卡合头234F时，卡合头连接部233F恢复到未变形的状态，并将卡合头234F推动到锁定槽122F内，从而使卡合头234F与锁定槽122F卡合。此时，第一扣件1F与第二扣件2F完成锁定。
当欲使第一扣件1F与第二扣件2F解除锁定时，按压两侧的按压部231F，以使两个按压部231F朝向接纳孔211F移动。两个按压部231F朝向接纳孔211F的移动带动弹性结构232F的与按压部231F相连的一端移动。此时，弹性结构232F的末端以及延伸部236F与纵向导向肋212F抵接，使弹性结构232F发生变形。同时，弹性结构232F的末端以及延伸部236F沿着纵向导向肋212F的抵触面往外(沿纵向Y远离接纳孔211F)滑移，从而带动卡合头234F离开接纳孔211F。此时，由于配锁部12F未被卡合头234F锁定，配锁部12F可沿与配锁部12F插入接纳孔211F的方向的相反方向移动到第二扣件2F之外，从而实现第一扣件1F与第二扣件2F的分开。
第十三实施例的其他内容可参见第十一实施例。
在本申请的实施例中，弹性结构具有纵向的区段(第十一实施例和第十二实施例中的第一区段2321F，或者第十三实施例中的延伸部236F)，用来在第二扣件2F的按压部231F被操作时与第二扣件2F的壳体20F上的抵接部(凸柱221F或者纵向导向肋212F)抵接，使沿横向的操作(按压部231F横向的位移或者弹性结构232F的第一端的横向位移)转换成弹性结构232F的第二端的纵向位移，或者使沿横向的操作(按压部231F向内的运动或者弹性结构232F的第一端向内的运动)转换成弹性结构232F的第二端向外的运动。
第一磁体5F与第二磁体6F在第一扣件1F和第二扣件2F的对插过程中相互磁性吸附或磁性排斥。第一扣件1F或第二扣件2F还具有活动地设置于其上的释锁操作件(按压部231F)。当操作释锁操作件使锁定部(卡合头234F)与配锁部12F之间释锁以允许第一扣件1F与第二扣件2F相互拔出时，第一磁体5F与第二磁体6F磁性吸附而使第一扣件1F与第二扣件2F保持对插状态；或者，第一磁体5F与第二磁体6F磁性排斥而使第一扣件1F与第二扣件2F相互分离。
在本申请的实施例中，当操作释锁操作件使锁定部(卡合头234F)与配锁部12F之间释锁以允许第一扣件1F与第二扣件2F相互拔出时，第一磁体5F与第二磁体6F可保持相对位置关系。
在本申请的实施例中，当操作释锁操作件使锁定部(卡合头234F)与配锁部12F之间释锁以允许第一扣件1F与第二扣件2F相互拔出时，第一磁体5F与第二磁体6F可保持沿第一扣件1F和第二扣件2F彼此对插配合的方向的对准。
