Wherein, the first bowl-shaped seat is connected with the first assembly plate or the second assembly plate 109 at the corresponding position, the second bowl-shaped seat 505 is detachably connected on the lower end face of the chain plate, one ends of the two connecting rods 502 far away from each other are respectively provided with a connecting ball head 504, the two connecting ball heads 504 are respectively movably assembled in the corresponding first bowl-shaped seat and the second bowl-shaped seat 505, one ends of the two connecting rods 502 near each other are respectively connected with two ends of the adjusting sleeve 501 in a threaded manner, and the axes of the adjusting sleeve 501 and the two connecting rods 502 coincide. In this embodiment, a lock nut 503 is screwed on each connecting rod 502, and the lock nut 503 is locked on the corresponding end face of the adjusting sleeve 501. After the universal pulling member 500 is tensioned when pulling the chain plate, when the chain plate bears external force and buffers the external force, the chain plate vibrates or displaces to a certain extent, at this time, the end parts of the two connecting rods 502 on the universal pulling member 500 can twist correspondingly with the first bowl-shaped seat and the second bowl-shaped seat 505, so as to adapt to the action of the chain plate, so that the chain plate is always in a tensioned state, and part of the external force is unloaded onto the universal pulling member 500 by the chain plate, thereby avoiding the influence of the concentrated stress of the chain plate on the service life of the chain plate. Meanwhile, part of external force can be shared by the steel wire ropes 108 connected with the chain plate, and the steel wire ropes 108 have certain flexibility and toughness, so that the performance of the steel wire ropes is directly reflected on the chain plate, and the buffering capacity of the chain plate is improved.
