[0008] Furthermore, a threaded hole is provided at the center of the limiting top plate for tightening the bolt to lock the track.

[0009] Furthermore, the end of the limiting top plate and the end of the supporting bottom plate are both arranged with arc-shaped chamfers to facilitate turning over of the tooling.

[0010] The advantages of the present invention are:

[0011] 1) In the present invention, the tooling is split into three structures: a clamping plate, a supporting bottom plate, and a limiting top plate. When the track is hoisted, the tooling can be clamped from the track end or assembled on site. This structure is applicable to I-shaped tracks of different sizes.
