请参阅图4，对于所述卡爪组件300，其包括基座310、至少一个外延臂320以及至少一个卡爪330，所述基座310与所述外延臂320连接，一所述卡爪330对应安装于一所述外延臂320，所述基座310与所述导向组件200连接，并且所述基座310沿着所述导向组件200移动。具体地，所述基座310设有两个导向孔311，两个所述导向孔311用于供所述第一导向柱210以及所述第二导向柱220安装使用，即所述第一导向柱210依次穿过两个所述卡爪组件300的一所述导向孔311，所述第二导向柱220依次穿过两个所述卡爪组件300的另一所述导向孔311，随后通过两个所述连接片230将所述第一导向柱210以及所述第二导向柱220连接。由此，实现了所述卡爪组件300与所述导向组件200的连接，所述卡爪330随所述基座310的滑动而进行移动。在本实施例中，一所述卡爪组件300的所述外延臂320的数量为两个，所述卡爪330的数量也为两个，并且两个所述卡爪330一一对应安装于两个所述外延臂320，并且对称设置。因此，所述轮毂夹持装置900安装于所述轮毂时，通过四个所述外延臂320上的四个所述卡爪330共同夹持所述轮毂，从而确保两个所述卡爪组件300的中心与所述轮毂的中心对齐。
请结合图5与图6，对于所述牵引模块400，其包括转动板410、第一连杆420以及第二连杆430，所述转动板410可转动地安装于所述主体100，所述第一连杆420以及所述第二连杆430的一端均与所述转动板410连接，所述第一连杆420的另一端与一所述卡爪组件300连接，所述第二连杆420的另一端与另一所述卡爪组件300连接。具体的，所述连接板410的中心处设置有连接孔411，所述连接板410通过所述连接孔411套设于所述中心轴部1211，并且通过螺栓实现连接。所述第一连杆420的一端与所述转动板410连接，所述第一连杆420的另一端与一所述卡爪组件300的所述基座310连接，所述第二连杆430的一端与所述转动板410连接，所述第二连杆430的另一端与另一所述卡爪组件300的所述基座310连接。
可理解的，所述第一连杆420以及所述第二连杆430的长度可以是一样长，当然也可以是不一样的长度，例如：当所述第一连杆420的长度长于所述第二连杆430的长度时，所述第一连杆420的一端距离所述转动板410的中心的距离，相比于所述第二连杆430一端与所述转动板410中心的距离要远一些，以使所述转动板410转动时，所述第一连杆420的另一端拉着一所述卡爪组件300移动的距离，能够与所述第二连杆430的另一端拉着另一所述卡爪组件300移动的距离相同，从而确保两个所述卡爪组件300的中心与所述牵引模块400的中心重合。
优选地，所述第一连杆420与所述第二连杆430的长度相同，并且所述第一连杆420的一端与所述转动板410中心的距离，以及所述第二连杆430的一端与所述转动板410中心的距离，此两者的距离相同，从而可以更好地确保两个所述卡爪组件300在所述牵引模块400的作用下移动相同的距离。值得说明的是，两个所述卡爪组件300在安装于所述导向组件200时，两个所述卡主组件300的所述基座310距离所述转动板410的中心距离需确保相同，从而当一所述卡爪组件300移动后，在所述牵引模块400的作用下，才能使得另一所述卡爪组件300移动后所述转动板410的中心轴线处于两个所述卡爪组件300的中心处。
通过上述结构，所述轮毂夹持装置900在安装于轮毂时，用户拉动一所述卡爪组件300移动，另一所述卡爪组件300受所述牵引模块400的作用移动了相同的距离，待调整到两个所述卡爪组件300张开的幅度与所述轮毂的外形尺寸相适配时，仅需将两个所述卡爪组件300的所述卡爪330分别插装到所述轮毂与轮胎的安装缝隙处，即可将所述轮毂夹持装置900快速地安装到所述轮毂上，从而对车轮进行定位和测量。
请结合图7-10所示，在一些实施例中，所述轮毂夹持装置900还包括锁紧模块500，所述锁紧模块500安装于所述主体100，所述锁紧模块500用于锁紧所述牵引模块400，以使所述卡爪组件300卡紧所述轮毂。在本实施例中，所述锁紧模块500安装于所述安装板120。
所述锁紧模块500包括锯齿条510、棘爪组件520、限位杆530以及手柄 540，所述锯齿条510安装于所述转动板410，所述限位杆530的一端与所述棘爪组件520连接，所述限位杆530的另一端转动地连接于所述主体100，所述棘爪组件300连接所述手柄540，所述手柄540的一端可转动地安装于所述主体100。当所述手柄540转动时，所述棘爪组件520随所述手柄540移动，并且当所述棘爪组件520咬合所述锯齿条510时，所述转动板410处于锁紧状态，当所述棘爪组件520与所述锯齿条510分离时，所述转动板410处于解锁状态。
具体的，所述锯齿条510安装于所述转动板410的侧部，并且所述锯齿条510的锯齿朝远离所述转动板410的方向设置。所述限位杆530的一端与所述棘爪组件520铰接，所述限位杆530的另一端套设于所述安装板120的所述中心轴部1211，并且所述限位杆530的整体长度大于所述转动板410的转动半径。所述手柄540可转动地与所述转动板410的第一凸柱1212铰接。由此，当所述手柄540以所述第一凸柱1212的中心轴线为转动中心转动时，所述手柄540带动所述棘爪组件520移动，以间接带动所述棘爪组件520移动，使得所述棘爪组件520咬合或不咬合所述锯齿条510。
在一些实施例中，所述锯齿条510与所述转动板410一体成型，即所述转动板410的侧端开设处若干锯齿，以形成所述锯齿条510。当然，所述锯齿条510与所述转动板410也可以独立设置，在本实施例中，所述锯齿条510与所述转动板410一体成型，以减小所述夹持装置900的组装难度，同时确保所述棘爪组件520与所述锯齿条510装配的准确性。
请参阅图9，在一些实施例中，所述棘爪组件520包括活动块521、棘爪522以及连接件523，所述活动块521与所述限位杆530连接，所述棘爪522的一端可转动地安装于所述活动块521，所述棘爪522的另一端用于勾抓所述锯齿条510，所述连接件523的一端与所述活动块521连接，所述连接件523的另一端与所述手柄540连接。在本实施例中，所述活动块521整体形状呈U形状，其包括第一凸耳部5211、第二凸耳部5212以及弧部5213，所述弧部5213的一端与所述第一凸耳部5211连接，所述弧部5213的另一端与所述第二凸耳部5212连接，所述第一凸耳部5211以及所述第二凸耳部5212间隔设置，以形成一容纳空间，其中，所述第一凸耳部5211上设有安装部52111，所述弧部5213设有连接孔52131。所述棘爪522可转动地安装于所述第一凸耳部5211以及所述第二凸耳部5212之间，可以是通过一安装轴依次穿过所述第一凸耳部5211、所述棘爪522以及所述第二凸耳部5212以实现所述棘爪522安装于所述活动块521，也可以是所述第一凸耳部5211或者所述第二凸耳部5212向所述容纳空间内延伸以形成供所述棘爪522安装的位置。所述连接件523的一端连接于所述活动块521，所述连接件523的另一端与所述手柄540连接。
可理解的，所述连接件523可以是一杆状的连杆，此时该连杆的一端与所述活动块521铰接，连杆的另一端与所述手柄铰接；当然，所述连接件523 也可以是拉簧，该拉簧的一端与所述活动块521的所述连接孔52131连接，拉簧的另一端与所述手柄540连接。在本实施例中，所述连接件523为拉簧。由此，当所述手柄540朝远离所述棘爪522的方向转动，即所述手柄540沿着预设方向转动时，所述手柄540逐渐拉伸所述拉簧，待所述手柄540转动到所述棘爪522咬合所述锯齿条510时，所述手柄540仍沿着预设方向转动并且拉伸所述拉簧，以使所述转动板410具有朝预设方向转动的趋势，从而所述转动板410通过第一连杆420以及所述第二连杆430来带动两个所述卡爪组件300朝中心靠拢的趋势，以便所述牵引模块400两侧的卡爪330共同夹紧所述轮毂。在本实施例中，所述预设方向为逆时针方向。
在一些实施例中，所述锁紧模块500还包括扭簧550，所述扭簧550安装于所述活动块521，且所述扭簧550的一端与所述活动块521抵接，另一端则与所述棘爪522抵接，所述扭簧550用于向所述棘爪522提供朝向所述锯齿条510的压力。具体的，所述扭簧550套设于所述安装部52111，并且所述扭簧550的一端与所述弧部5213抵接，所述扭簧550的另一端与所述棘爪522抵接。
当所述棘爪522朝所述抬升块1215的方向运动，以使所述抬升块1215插入所述棘爪522和所述锯齿条510之间，将所述棘爪522和所述锯齿条510分离时，所述转动板410处于解锁状态，当所述棘爪522朝远离所述抬升块1215的方向运动，以使所述棘爪522和所述锯齿条510不再受所述抬升块1215分离时，在所述扭簧550的作用下，所述棘爪522朝向所述锯齿条510运动，并且咬合所述锯齿条510，以使所述转动板410处于锁紧状态。
在一些实施例中，所述锁紧模块500还包括连接轴560，所述手柄540设有第一滑槽541以及第二滑槽542，所述第一滑槽541与所述第二滑槽542对称设置于所述手柄540的两侧，所述连接轴560安装于所述第一滑槽541与所述第二滑槽542之间，所述连接件523连接所述连接轴560，转动所述手柄540，以使所述连接轴560于所述第一滑槽541以及所述第二滑槽542内滑动，从而拉动所述活动块521带动所述棘爪522移动。可理解的，当所述手柄540朝所述预设方向转动时，所述连接轴560逐渐移动到所述第一滑槽541以及所述第二滑槽542的端部，所述手柄540继续朝所述预设方向转动，所述棘爪522咬合所述锯齿条510，从而带动所述转动板410转动，以便两个所述卡爪组件300共同夹紧所述轮毂。
在一些实施例中，所述锁紧模块500还包括限位块570，所述限位块570的一端与所述主体100转动连接，所述限位块570的另一端与所述手柄540转动连接。具体的，所述限位块570的一端与所述安装板120的所述第二凸柱1213连接，所述限位块570的另一端与所述手柄540铰接。可理解的，当所述棘爪522咬合所述锯齿条510时，继续转动所述手柄540，当所述第二凸柱1213的中心、所述活动块521与所述限位杆530连接点处以及所述连接轴560的中心三者处于同一直线时，所述活动块521、所述限位杆530、所述限位块 570以及所述手柄540之间处于卡死状态，所述手柄440继续沿所述预设方向转动，所述拉簧绷直而不动弹，此时两个所述卡爪组件300紧紧卡接所述轮毂，当沿着与所述预设方向相反的方向转动时，所述拉簧逐渐恢复变形，从而使所述锁紧模块逐渐解锁。
在一些实施例中，所述锁紧模块500还包括回复件580，所述回复件580的一端固定于所述主体100，所述回复件580的另一端连接于所述棘爪522。在本实施中，所述棘爪522上连接有转轴(未标示)，所述回复件580的一端连接所述第三凸柱1214，所述回复件580的另一端连接于所述棘爪522的所述转轴。

请再次参阅图1，在一些实施例中，所述轮毂夹持装置900还包括把手600，所述把手600安装于所述卡爪组件300，所述把手600受外部拉动以提供所述卡爪组件300移动的外力。在本实施例中，所述把手600安装于所述卡爪组件300的所述基座310，使用时，用户仅需握持所述把手，并朝着靠近或远离所述主体100的方向拉动，即可带动所述卡爪组件300靠近或远离所述主体100。
安装使用时，用户仅需移动其中一个卡爪组件300，在所述牵引模块400的作用下，所述转动板410绕着所述主体100的中心轴线转动一定的角度，从而带动另一所述卡爪组件300移动相同的距离。待两个所述卡爪组件300的所述卡爪330张开的幅度适配所述轮毂的外形尺寸后，仅需将两个所述卡爪组件300的所述卡爪330卡接于所述轮毂与轮胎中间的安装缝隙中，即可将所述轮毂夹持装置900依附于车轮上。进一步地，为了提高所述夹持装置900与所述车轮之间的稳固性，所述轮毂夹持装置900还设置有锁紧模块500，具体的，用户仅需掰动所述手柄540，使得所述活动块521、所述限位杆530、所述限位块570以及所述手柄540之间处于卡死状态，以使所述锁紧模块500处于完全锁紧状态，在所述手柄540移动的过程中，所述棘爪522从所述抬升块1215脱离，并且咬合所述锯齿条510，随后所述拉簧被拉伸，待所述拉簧绷直后，所述手柄540继续转动，所述棘爪522带动所述转动板410转动，两个所述卡爪组件300朝所述主体的中心轴线略微移动，从而所述轮毂夹持装置900更好地夹紧所述轮毂，待所述手柄540处于卡死状态时，松开手柄540，此时若无外力作用，所述锁紧模块500将一直保持锁死状态。其中，两个所述卡爪组件300对称设置于所述主体100的两侧，并且关于所述主体100的中心轴线对称。加上两个所述夹爪组件200通过两个对称设置的连杆间接地与所述转动板410连接，可以确保两个所述卡爪组件300的时刻移动相同的距离，从而确保了所 述夹持装置900安装于所述车轮时，所述主体100的中心轴线与所述轮毂的中心轴线重合。可理解的，当需要将所述轮毂夹持装置900自车轮上卸下时，仅需将所述手柄朝着与所述预设方向相反的方向转动，使得所述锁紧模块500处于解锁状态，随后再解除两个所述卡爪组件300的卡爪330自所述安装缝隙中取出，即可实现将所述轮毂夹持装置900自车轮上卸除，安装及拆卸极为方便。
