[0006] The clamping member includes a support for supporting the I-shaped part; positioning bars are arranged on both sides of the support, and the two positioning bars are mounted on the same threaded rod; as the threaded rod rotates, the two positioning bars approach each other to clamp and fix the lower panel of the I-shaped part.

[0007] Preferably, at least one pin hole is provided on the support, and a positioning pin penetrates through the pin hole and is inserted into an adjustment groove arranged along the length direction of the adjustment track to fix the clamping member at any position on the adjustment track.

[0008] Preferably, two pin holes are provided, symmetrically distributed on both sides of the support.

[0009] Preferably, a trapezoidal slider is arranged below the positioning bar, and the trapezoidal slider slides back and forth in the support.

[0010] Preferably, the trapezoidal slider is internally machined with an internal thread, and is threadedly connected to the threaded rod through this internal thread.

[0011] Preferably, the internal thread directions of the two trapezoidal sliders are opposite. As the threaded rod rotates, the two trapezoidal sliders drive the two positioning bars to approach or move away from each other respectively.

[0012] Preferably, the contact surfaces of the two positioning bars and the I-shaped part are machined with internal chamfers.

[0013] Preferably, a rotating handle is provided at the end of the threaded rod, and the threaded rod is driven to rotate through the rotating handle.
