第二实施例：
该第二实施例中的伸缩式快速夹与第一实施例的区别在于第二实施例中的第一夹钳30和第二夹钳40与第一实施例的第一夹钳3和第二夹钳4的结构是不相同的。请详细参见图5所示，图5为本发明的第二实施例的结构示意图。
图5中，第一夹钳30为一方形，其下端设有通孔。所述第一夹钳30通过通孔套设并固定于第一尺杆1上。在第一夹钳的上端设有第一夹头5。
第二夹钳40包括一设有内腔的方形主体，所述第二尺杆2穿过所述内腔，所述内腔内设有锁紧所述第二尺杆的机构，并通过一设于所述内腔外的按钮控制（图中未详细描述出）。方形主体上端设有一螺纹通孔。所述驱动手柄70为一前端设有螺纹旋杆701的手柄。所述螺纹旋杆701穿过所述方形主体上端的螺纹通孔与所述第二夹头6相连接，通过旋转所述手柄带动所述第二夹头6向所述第一夹钳上的第一夹头5靠近或远离。
为了调节喉深，该第二实施例中在所述第一夹钳30的本体上设有可拉伸以调整所述第一夹头高度的伸缩结构，所述第二夹钳40的本体上设有可拉伸以调整所述第二夹头高度的伸缩结构。参见图6所示，图6为本发明的第二实施例的一使用状态结构示意图。在此使用状态中，将第一夹钳的本体和第二夹钳的本体进行拉伸以调节第一夹钳的本体和第二夹钳的本体的伸展高度。伸缩结构并不限定唯一，任何可以实现伸缩的结构都可以用于其上。
第二实施例的使用与第一实施例相同，第一夹钳30和第二夹钳40均可以在相应的第一尺杆1和第二尺杆2上进行方向和距离的调节。同时，所述第一夹钳30和所述第二夹钳40的上端连接所述第一夹头5和所述第二夹头6处分别设有滑槽，所述第一夹头和所述第二夹头沿着所述滑槽可移动并固定在所述第一夹钳和所述第二夹钳上的合适的位置，可以进一步的实现喉深的距离调节。
第三实施例：
参见图7所示，图7为本发明的第三实施例的结构示意图。与第二实施例的区别在于：第三实施例的第一夹钳31的形状与第二实施例中的第一夹钳30的形状不相同。在该第三实施例中，第一夹钳31的本体并非第二实施例里的方形本体，第三实施例中的第一夹钳31的外侧面呈现有弧度，以便更好的与工件匹配。
在第三实施例中，第一夹钳31的本体和第二夹钳41的本体上设有的伸缩结构为滑槽和滑块的方式。当然，伸缩结构也可以是其他的方式，并不限定。
第四实施例：
参见图8和图9所示，图8为本发明的第四实施例的局部结构示意图；图9为本发明的第四实施例的结构示意图。
所述第一夹钳3上设有一按钮开关30，当按压所述按钮开关32时，所述按钮开关32与所述第一尺杆1解锁，所述第一夹钳3可相对所述第一尺杆1任意滑动。当松开所述按钮开关32时，所述按钮开关32可自动对准所述第一尺杆上的固定孔并与该固定孔锁紧以固定所述第一夹钳和所述第一尺杆。如图9所示，所述第二尺杆2上设有至少一个限位孔，且所述第二尺杆上设有一按钮开关20，当按压所述按钮开关20时，所述按钮开关20解锁所述第一尺杆1和所述第二尺杆2，所述第一尺杆1和所述第二尺杆2可相对滑动。当松开所述按钮开关20时，所述按钮开关20对准所述第一尺杆1上任一所述固定孔以及所述第二尺杆2上一限位孔并将所述固定孔和所述限位孔锁紧以固定所述第一尺杆和第二尺杆的位置。该设计可以免去繁琐的人工孔位对准步骤，连接时操作简单，省时省力。
第五实施例：
参见图10所示，图10为本发明的第五实施例的结构示意图。该第五实施例与第三实施例不同之处在于：第五实施例的驱动手柄还包括一旋盖702，所述旋盖702设于所述螺纹旋杆701与手柄70之间，所述手柄70为棘轮式驱动结构，通过调节旋盖可实现所述手柄的往复式旋转，易于使用者的操作。同时，第一尺杆1和第二尺杆2通过按钮开关20固定在一起。
第六实施例：
参见图11所示，图11为本发明的第六实施例的结构示意图。该第六实施例与第三实施例的不同之处在于：第六实施例的手柄70相对所述螺纹旋杆701可以转动，更加方便使用者的使用。同时，第一尺杆1和第二尺杆2通过按钮开关20固定在一起。
为了便于更清楚的了解移动的位置，所述第一尺杆和所述第二尺杆的两侧分别设有公/英制对应的长度单位。
作为本申请的延伸，还可以有其余的更多的实施例。如尺杆的数量并不只有两根，还包括多根加长尺。在实施时，其中一加长尺连接并固定在所述第二尺杆上，其余各所述加长尺分别依次连接并固定，所述第二夹钳可连接并固定在任一所述加长尺上，所述第二夹钳可沿着任一所述加长尺直线移动。
应理解，这些实施方式仅用于说明本发明而不用于限制本发明的范围。此外应理解，在阅读了本发明讲授的内容之后，本领域技术人员可以对本发明作各种改动或修改，这些等价形式同样落于本申请所附权利要求书所限定的范围。
