The two U-shaped clamping plates 17 located on the same side are symmetrically and threadedly connected to the corresponding double-headed screw 18. It is worth noting that the double-headed screw 18 can be limited by the sliding groove 19, so that it cannot rotate, and can only linearly slide.

[0027] Each clamping mechanism comprises a U-shaped seat 10, and the U-shaped seat 10 is fixedly installed on the outer side of the rotating frame 8; a second electric telescopic rod 11 is fixedly installed on the outer side of each U-shaped seat 10; a square frame 12 is fixedly installed at one end of each second electric telescopic rod 11; each square frame 12 penetrates through the rotating frame 8 and extends into the rotating frame 8; a clamping plate 13 is installed on the outer side of each square frame 12; the clamping plate 13 is guided to avoid deviation by sliding on the rotating frame 8 through the square frame 12; and the extension distance of the clamping plate 13 can be extended.
