[0051] Among them, the two symmetric parts of the traction connection assembly 2 are respectively arranged on the vehicle bottom plate 1 of the conveying device and the rear transportation section, and then inserted. When the two locking plugs 204 are inserted into each other's connection pair slots 202, the locking rotating blocks 210 inside rotate under the action of the inner wall of the locking plug 204, and at the same time, the spring pull rod 216 connected to the unlocking handle 211 is pulled. After the two locking rotating blocks 210 are spliced together, in the locking rotating groove 207 formed by the combination of the two rotating circular groove shells 206, it is pulled back to its original state under the action of the spring pull rod 216, and the splicing boundary rotates and is stuck in the locking rotating groove 207 to form a lock. When one unlocking handle 211 is pulled to align its splicing boundary with the slot calibration plate 205, it can be pulled out for unlocking.
