当所述第一被连接件100与所述第二被连接件200组装状态下，保证所述锁紧块310与所述锁止孔320位置相对应，之后控制所述锁紧块310向锁止孔320方向移动，直至其伸入所述锁止孔320中，实现所述第一被连接件100与所述第二被连接件200的锁定。
当需要解除所述第一被连接件100与所述第二被连接件200之间的锁定时，只需要控制所述锁紧块310向远离所述锁止孔320的方向运动，至其完全退出所述锁止孔320，实现所述第一被连接件100与所述第二被连接件200相互锁定的解除。
当然，所述锁紧块310以及所述锁止孔320的设置方式并不局限于锁紧块310设置在所述第一被连接件100上锁止孔320设置在所述第二被连接件200上，在其他实施例中，还可以将锁紧块310设置在第二被连接件200上，锁止孔320设置在第一被连接件100上。
在本实施例中所述第一被连接件100以及第二被连接件200分别为中空的管状结构，锁紧块310设置在中空的管体内部，对其的操作需要通过用于驱动所述锁紧块310运动的驱动机构进行，所述驱动机构包括驱动控制部330以及在所述驱动控制部330的作用下可移动的
驱动执行部340，所述驱动执行部340带动所述锁紧块310运动。
在本实施例中所述驱动执行部340与所述锁紧块310固定连接。
在其他实施例中还可以将所述驱动执行部340与所述锁紧块310设置为一体结构。
为了便于安装所述驱动机构，所述第一被连接件100具有用于安装所述驱动机构的驱动安装板350，本实施例所述的驱动安装板350为呈矩形中空管状结构的第一被连接件100的第一侧壁，所述驱动控制部330设置在所述驱动安装板350的一侧，该侧为管状结构的外侧，可以通过其在外部控制锁紧块310的动作，所述驱动执行部340穿过所述驱动安装板350与所述驱动控制部330传动连接。

在本实施例中，所述锁紧块310为两块，分别设置在所述连接片342的两端部。所述连接片342的中部与驱动螺杆341固定连接。
为了进一步保证锁紧效果，所述锁紧块310为锥形结构，所述锁止孔320为与所述锁紧块310外形相对应的锥形孔。
于本实施例中，所述锁止孔320为贯穿所述驱动安装板350的通孔，通过将锁止孔320设计成通孔，能够方便的在一侧观察到所述锁紧块310伸入所述锁止孔320中的距离，从而判断锁止与解锁动作的完成情况，更为合理的操作旋转把手，避免过度旋转造成旋转把手与驱动螺杆341之间的传动结构受损而影响使用效果。
在本实用新型的其他实施例中还可以将锁止孔320设置为不贯穿所述驱动安装板350的盲孔，设置为盲孔的好处为可以保证第二被连接件200外观的完整性，保证产品美观。
本实施例中还提供一种折叠车，包括作为第一被连接件100的上车体以及作为第二被连接件200的下车体，所述上车体与所述下车体采用如上所述的锁紧机构进行锁紧。
所述上车体与下车体的连接方式可以为铰接或插接，本实施例中采用铰接的方式，所述锁紧机构与所述上车体和所述下车体相互铰接的位置相对设置。
本实用新型锁紧状态时，驱动控制部330的端面与复位件挡片345的端面摩擦接触，达到摩擦力锁紧效果，保证锁紧块310在轴向方向不能产生移动。
锁紧块310插入第二被连接件200。两者是锥面紧配。通过上述动作，第一被连接件100和第二被连接件200达到锁紧效果。
本实用新型解锁时，驱动控制部330需要旋转180°才能解锁。对比附图5与附图8。
本实用新型解锁时，驱动控制部330旋转时，因为螺纹传动的作用，驱动螺杆341随着做轴向运动。因为弹性复位件343的作用，驱动螺杆341只能向内侧滑动。驱动螺杆341带动锁紧块310向内侧运动。从而锁紧块310从第二被连接件200脱出。从而第一被连接件100和第二被连接件200达到解锁效果。
需要声明的是，上述具体实施方式仅仅为本实用新型的较佳实施例及所运用技术原理，在本实用新型所公开的技术范围内，任何熟悉本技术领域的技术人员所容易想到的变化或替换，都应涵盖在本实用新型的保护范围内。
