在一些实施例中，所述锁紧模块300还包括扭簧370，所述扭簧370安装于所述连杆组件330，并且所述扭簧370的一端与所述连杆组件330抵接，另一端则与所述棘爪340相抵接。具体的来说，所述扭簧370安装于所述限位杆331的一端，并且所述扭簧370一端与所述限位杆331相抵接，所述扭簧370的另一端与所述棘爪340相抵接。当所述棘爪340朝所述抬升块312运动时，以使所述抬升块312插入所述棘爪340和所述棘轮320之间，所述扭簧370两端受挤压，此时所述扭簧370处于挤压状态；当所述棘爪340朝远离所述抬升块312的方向运动，所述棘爪340和棘轮320不再受所述抬升块312分离时，所述扭簧370恢复原状，以驱使所述棘爪340朝所述棘轮320运动，以使所述棘爪340咬合所述棘轮320。可理解的，此时所述棘爪340不受所述轮毂夹持装置900安装位置的限定，所述轮毂夹持装置900可随意安装于轮毂上，当需要锁紧所述棘轮320时，仅需转动所述手柄350，使得所述棘爪340和棘轮320不在受所述抬升块312分离，所述扭簧370驱动所述棘爪340咬合所述棘轮。
在安装使用过程中，当需要锁紧所述驱动杆200时，用户可沿着预设方向转动所述手柄350，所述手柄350带动所述连杆组件330摆动，并在摆动的过程中使得所述棘爪340和棘轮320不再受所述抬升块312分离，所述棘爪340朝向所述棘轮320运动，并且所述棘爪340咬合所述棘轮320，从而间接锁紧所述驱动杆220，以此确保两个所述卡爪组件100在卡接于所述轮毂时，两个所述卡主组件100无法朝远离所述装夹模块400的方向移动，使得两个所述卡爪组件100卡紧所述轮毂，确保了所述装夹模块400的中心轴线与所述轮毂的中心轴线重合，提高校准设备的定位精度。同时，相较于现有的轮毂夹持装置，本发明实施例中的轮毂夹持装置，在使用过程中仅需转动所述手柄350，以使得棘爪340咬合所述棘轮320，从而间接锁定所述驱动杆220，从而快速完成对所述驱动杆220的锁定，使用起来较为方便。
请参阅图12，对于所述装夹模块400，其包括安装座410以及锁紧旋钮420，所述安装座410固定安装于所述驱动模块200，所述锁紧旋钮420活动安装于所述安装座410，其中，所述安装座410设有插孔4121，所述插孔4121用于插装辅助校准装置。当所述安装座410插装所述辅助校准工具时，拧动所述锁紧旋钮420，以使所述辅助校准装置与所述安装座410固定。
所述安装座410包括基台部411以及安装部412，所述基台部4112与所述安装部412连接，所述安装部412用于安装所述辅助校准装置。其中，所述基台部411设置第一安装孔4111以及第二安装孔4112，所述第一安装孔4111套设于所述第一导向柱211，所述第二安装孔4112套设于所述第二导向柱212，从而使得所述安装座410固定安装于所述导向组件210。所述安装部412设置有插孔4121以及螺孔4122，所述螺孔4121与所述插孔4121连通。
所述锁紧旋钮420包括螺杆421以及旋钮头422，所述旋钮头422与所述螺杆421连接，所述螺杆421螺接于所述螺孔4122。
这里要说明的是，所述辅助校准装置可以为带有校准图像的标靶、用于对 车辆校准设备进行定位或同车辆校准设备配合使用的激光器、反光装置等，在此不予限定。
使用时，旋转所述旋钮头422，以使得所述螺杆421沿着所述螺孔4122移动，当移动一定距离后，所述螺杆421的端部可抵接所述辅助校准装置，以所述辅助校准装置紧固安装于所述安装部412。其中，由于所述插孔4121的中心轴线与所述轮毂的中心轴线相重合，当所述辅助校准装置安装于所述插孔4121时，所述辅助校准装置的中心轴线与所述插孔4121的中心轴线重合，由此，所述辅助校准装置的中心轴线与所述轮毂的中心轴线重合。
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500，所述把手500安装于所述卡爪组件100。拉动所述把手500，所述驱动模块200驱动两个所述卡爪组件100同步靠近或远离所述装夹模块400。具体的，所述把手500包括把柄部510、第一连接部520以及第二连接部530，所述把柄部510的两端分别与所述第一连接部520以及第二连接部530的一端连接，所述第一连接部520的另一端与所述基座110的一端连接，所述第二连接部530的另一端与所述基座110的另一端连接。
如图13所示，安装使用时，用户只需双手握持两侧的所述把手500的所述把柄部510，并拉动两个所述卡爪组件100沿着所述导向组件210移动，在所述驱动杆220的作用下，确保了两个所述卡爪组件100移动相同的距离，使得所述装夹模块400始终处于两个所述卡爪组件100的中心处。请结合图10与图11，待两个所述卡爪组件100移动至与所述轮毂外轮尺寸相适配的位置后，将两个所述卡爪组件100的所述卡爪130插装于所述轮毂与轮胎的安装缝隙中，然后将所述手柄350沿预设方向转动，以使得所述棘爪340咬合所述棘轮320，受所述棘爪340的作用，此时所述棘轮320仅能沿所述预设方向转动，并且所述棘轮320与所述驱动杆220固定连接，因此所述驱动杆220仅能沿所述预设方向转动，从而两个所述卡爪组件100只能朝夹紧所述轮毂的方向移动，而不能朝松开所述轮毂的方向移动。由此，所述轮毂夹持装置900紧固安装于所述轮毂，并确保在使用过程中位置不发生变动，从而使所述装夹模块400的中心轴线始终与所述轮毂的中心轴线相重合。待所述轮毂夹持装置900闲置时，即无需用到所述轮毂夹持装置900时，仅需反向转动所述手柄350，使得所述棘爪340与所述棘轮320分离，从而解除所述锁紧模块的锁定，所述驱动杆220可沿与所述预设方向相反的方向转动，以使两个所述卡爪组件100朝远离所述轮毂的方向移动，从而用户可直接卸下所述轮毂夹持装置900。
本发明实施例提供的轮毂夹持装置900，包括两个卡爪组件100，用于卡接于轮毂，以使轮毂夹持装置依附于轮毂；驱动模块200，与两个所述卡爪组件100连接，所述驱动模块200包括导向组件210以及驱动件220，所述驱动件220与所述导向组件210连接，所述导向组件210用于引导两个所述卡爪组件100移动，所述驱动件220用于同步驱动两个所述卡爪组件100相互靠近或远离，且两个所述卡爪组件100的移动距离相同；锁紧模块300，安装于所述 驱动模块200，所述锁紧模块300用于锁紧所述驱动件220，以使两个所述卡爪组件100共同夹紧所述轮毂；装夹模块400，安装于所述驱动模块200，所述装夹模块400位于两个所述卡爪组件100的中心位置，所述装夹模块400用于装夹辅助校准工具；当所述驱动模块200驱动两个所述卡爪组件100移动至预设位置，以夹紧所述轮毂时，所述锁紧模块300锁紧所述驱动件220，以使所述装夹模块400的中心轴线与所述轮毂的中心轴线保持对齐。由此，在安装轮毂夹持装置时，仅需直接拉动两个所述卡爪组件100移动到所需位置，并通过锁紧模块300锁紧驱动件220，使得两个卡爪组件共同夹紧轮毂，使用起来更为方便。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
