Both beam frames 101 include an H-shaped section at the front and a T-shaped section at the middle and rear. The H-shaped section is welded to the U-shaped frame 31 after being buckled into the fixed clamp 302. An 8mm thick rubber buffer pad 13 is attached to the cross beam 11 of the T-shaped section. A through long slot fixing hole 14 is opened on the cross beam 11 and the buffer pad 13. A bayonet 121 is provided on the vertical beam 12 of the T-shaped section.
