It ensures that the shield machine can advance stably during the excavation process through structural support and reaction force transmission, avoiding equipment instability or displacement due to excessive reaction force.

[0003] The hydraulic cylinder of the shield's reverse pulling device is its important force transmission component. When reverse pulling is performed, the reverse pulling and pushing are achieved through the connection between the hydraulic cylinder and the traction steel bar. In order to ensure the normal and stable movement of the shield machine, multiple sets of hydraulic cylinders need to be installed. Each hydraulic cylinder requires multiple bolts to tighten it, which is cumbersome to operate and cannot achieve convenient installation and removal of the hydraulic cylinder. The installation and removal efficiency of the hydraulic cylinder is relatively low, and it takes a long time, which makes the work intensity of the staff higher. Summary of the Invention
