靠近缺口处的两板1、2中部之间通过两根支杆10安装挡座9，挡座9(远离缺口方向)固定连接两根相平行且呈上下布置的杆11，杆11的另一端伸入套杆13之内，两者伸缩式配合。套杆13的另一端固定于移动座14。杆11及套杆13之外套入弹簧12，弹簧12的两端分别顶于挡座9、移动座14。
移动座14的上下面分别通过两个支点15固定连接移动条16，上下移动条16的两端之间分别通过移动杆17相连。
与缺口相对侧的上下板间固定连接一座25，该座25凸出于安装板之外，其一外侧面固接电磁铁26，电磁铁的活动杆26-1两端都伸出于外且两端分别外套弹簧27、28。锁钩18(形成钩槽的)一端之下固接顶杆33，顶杆33与活动杆 26-1其中一端相适配而动作，在触发时，活动杆的该端能顶触顶杆33；而弹簧28顶压于顶杆33，通过顶杆33的作用力而将锁钩18(的钩槽)压向相对应的支轴8。当电磁铁26失电后，蓄能弹簧27拉动活动杆26-1的一端，而使活动杆26-1的另一端顶触顶杆33，进而使锁钩18脱离了对于相应支轴8的锁定。
座25还固定安装有电机29，电机29的电机轴通过减速机构与螺杆30连动，螺杆30外套并旋接螺套31，螺套31处于座25内，螺杆30旋转能带动螺套31移动。而当螺套31向外旋出时，其能推动锁钩18作回复动作但不会阻碍其触发动作，且其一端伸出座25之外并能推动移动座14作回复动作但不会阻碍其触发动作。螺套31的两侧还垂直固定连接一导杆32，与此相对应的，座25的两侧各形成一道滑槽25-1，滑槽置入相对应的导杆32而滑动配合，从而使螺套31在移动过程中不会转动。
常态下，两侧的制动块5远离电梯导轨4，而移动杆17刚好置于顶触臂7的凹口处，弹簧12处于压缩状态；而在弹簧28的作用下，锁钩的钩槽18-1钩于对侧的支轴8，使顶触臂7处于锁定状态，不能转动。参见图5。
当夹轨装置触发动作时，电磁铁26失电，活动杆26-1的一端在蓄能弹簧27的作用下向外冲击，其另一端顶触顶杆33，通过顶杆33带动锁钩18的转动，使其钩槽18-1脱离对于相应支轴8的锁定；此时，在弹簧12的作用力下，推动移动座14运动，进而使移动条16及移动杆17运动，在此过程中，移动杆17脱离了顶触臂7的凹口，逐渐向外侧顶压顶触臂7的边沿7-3，从而使两侧顶触臂7的该端向外转动，而另一端(靠近缺口一端)则向内转动，其顶触端的顶触面7-1朝对侧方向顶压制动块5，使制动块5向对侧平移，直至两侧的制动块5夹持住电梯导轨4。参见图6。
复位过程：启动电机29，其驱动螺杆30旋转，进而推动螺套31移动，螺套31向外旋出并推动移动座14及锁钩18作回复运动，直至到位；电磁铁26得电，弹簧28顶压顶杆33；而制动块5则在内置拉簧(图中未示，其两端分别固定于制动块的背面与同侧的竖板)作用下而复位。随后，电机29反转，螺套31复位。
实施例2：
如图9-16所示，顶板1与底板2的结构相同，都呈方状，并分别开有长方形缺口1-1、2-1，顶板1与底板2上下平行布设，且两者间的缺口上下相对应，两板的缺口用于穿伸电梯导轨4。以缺口为基准，两板1、2的两侧边之间分别通过数颗螺栓19固定连接一竖板3。
于缺口两侧的两板1、2之间各滑动配合一制动块5，制动块5呈方体状， 其上下表面各形成一方形凸条5-1，凸条5-1的方向与制动块5的滑动方向一致，与此相对应的，顶板1、底板2各形成滑槽A，滑槽内置入相对应制动块的凸条5-1并滑动配合。常态下，如图13所示，制动块5的夹持面与缺口的相对应边沿所在纵向平面持平，且两制动块5的夹持面相正对。当夹轨装置动作后，其制动块5向对侧滑动，直至两侧的制动块5夹持住电梯导轨4，参见图14。
制动块5的夹持面均匀地形成数条水平状的凹槽5-2，以使其具有更强的夹持力。
以长方形缺口为基准，于两板1、2之间的两侧分别通过轴6装配两片能转动的顶触臂7，同侧的上下两片顶触臂平行布设，两侧的顶触臂7对称设置，顶触臂7的一端为顶触端，该顶触端朝对侧呈圆弧凹形7-1，该部固接顶触件24，顶触件24的外侧面朝向对侧并顶触制动块5的背面(与夹持面相对的一侧面)。同侧的顶触臂7另一端之间还装配一支轴8。其中一侧的支轴8转动配合两锁钩18的一端，两锁钩18上下平行布设，且另一端通过连杆20相连。锁钩18的局部边沿形成钩槽18-1，钩槽与其它部分边沿都呈弧形状过渡。常态下，钩槽18-1钩于对侧的支轴8。
靠近缺口处的两板1、2中部之间安装挡座9，挡座9的两侧9-1分别伸入同侧的两顶触臂7之间，且纵向穿过轴6。挡座9(远离缺口方向)固定连接两根相平行且呈上下布置的杆11，杆11的另一端伸入套杆13之内，两者伸缩式配合。套杆13的另一端固定于移动座14。杆11及套杆13之外套入弹簧12，弹簧12的两端分别顶于挡座9、移动座14。
移动座14的外侧面(远离弹簧一侧)两边角处各形成一个外凸的弧形面14-1，两弧形面14-1分别正对同侧的支轴8。
同侧的两顶触臂7之间还固定连接挡条21，挡条21垂直连接杆22，杆22的另一端活动式地穿伸过同侧的竖板3。杆22外套弹簧23，弹簧23的两端分别顶于挡条21、竖板3，弹簧23对顶触臂7的该端产生一个向内的作用力。
电磁铁40通过一直角片42固定于一侧的竖板3，电磁铁23的活动头40-1外套一蓄能弹簧41，电磁铁40在通电状态下，活动头40-1内缩并压缩弹簧41。直角片40与连杆20的上端之间还连有拉簧43。
两安装板1、2间固定装配电机44，电机44的电机轴通过减速机构而与螺杆45连动，螺杆45通过螺纹旋接螺母46，当螺杆45旋转时，螺母46会沿螺杆45移动，且其能顶推锁钩18复位，而在常态下，螺母46不会对锁钩18的触发动作构成阻碍。
常态下，两侧的制动块5远离电梯导轨4；弹簧12处于压缩状态；锁钩的 钩槽18-1钩于对侧的支轴8，从而使顶触臂7处于锁定状态，不能转动。参见图13。
电磁铁40失电时，其活动头40-1在蓄能弹簧41的作用下向外冲击，并顶触连杆20，进而使锁钩18转动，锁钩的钩槽18-1脱离了对于对侧支轴8的锁定，又在弹簧12的作用力下，推动移动座14运动，在此过程中，移动座14的两弧形面14-1分别顶压同侧的支轴8，进而带动顶触臂7的此端逐渐向外侧转动，而另一端(靠近缺口一端)则向内(对侧)转动，使顶触件24朝对侧方向顶压制动块5，使制动块5向对侧平移，直至两侧的制动块5夹持住电梯导轨4。参见图14。
启动电机44，驱动螺杆45旋转，进而推动螺母46移动，螺母46逐渐顶压锁钩18而使其复位，其它部件反之动作而复位；而制动块5则在内置拉簧(图中未示，其两端分别固定于制动块的背面与同侧的竖板)的作用下而复位。随后，电机44反转，螺母46复位。
上述电磁铁、电机及减速机构等都是现有技术。
在实施例2中，可以将靠近顶触臂7的另一端处内侧边沿7-2(由内而外)设置成朝内倾斜的斜面状，而移动座14的两侧边沿与此边沿7-2相适配，在移动座14的动作过程中，通过移动座14的两侧边沿顶压同侧的顶触臂边沿7-2并使其此端逐渐向外侧转动(即移动座14与支轴8的顶压配合结构由上述替代)，也能实现制动块5夹持住电梯导轨4的目的。
以上对本发明的优选实施例进行了详细说明，对本领域的普通技术人员而言，依据本发明提供的思想，在具体实施方式上会有改变之处，而这些改变也应视为本发明的保护范围。
