In the present embodiment, two fixing holes 4 are provided, and the two fixing holes 4 correspond to the two mounting holes 2 one by one. The diameter of the fixing hole 4 is the same as the diameter of the mounting hole 2, so that the pin shaft 6 can pass through smoothly, and the accuracy and stability of the transition beam 3 during installation are improved.

[0020] Referring to Figure 1 and Figure 2 , the pin shaft 6 comprises a middle long rod and fixing heads at both ends. The diameter of the fixing head is greater than the diameter of the fixing hole 4, reducing the possibility of the pin shaft 6 falling off.

[0021] Referring to Figure 2 , the height of the adjusting hole 5 in the vertical direction is less than the height of the mounting hole 2. This design makes the position of the adjusting hole 5 not affected by the position of the mounting hole 2, and does not interfere with the use of the fixing hole 4 and the mounting hole 2.
