It can be appreciated that the shield 122 protects the head of the rail 170 from colliding with the rail 170 during lifting or removal.
In an alternative embodiment, as shown in fig. 1 to 4, the clamping pincers 150 comprise two clamping arms 151, the two clamping arms 151 are movably arranged on the box 120 through two rotating shafts 152, and the two clamping arms 151 rotate synchronously.
It can be understood that the two clamping arms 151 have the same structure and are movably or rotatably disposed on the box 120 through the rotating shaft 152, and the opening angle between the two clamping arms 151 is reduced or increased through the synchronous rotation of the two clamping arms 151.
In an alternative embodiment, there is a gap between the two clamping arms 151, and the wedge 140 is inserted into the gap.
It will be appreciated that there is a gap between the two clamping arms 151 which receives the wedge 140, wherein the shape of the wedge 140 and the gap match each other.
