[0041] In one of the embodiments, the first driver 100 comprises an electric cylinder, which provides power to the push rod 400.
[0042] In other embodiments, the first driver 100 can be an oil cylinder or an electric motor.
[0043] In one of the embodiments, the universal joint 700 comprises a rotating piece 710 and a locking piece 720, the rotating piece 710 is arranged at the power output end of the second driver 600; the rotating piece 710 is formed with a receiving notch 701 for receiving the connecting part of the side door of the BOP, and the locking piece 720 is arranged to pass through the through hole of the connecting part of the side door of the BOP, and the locking piece 720 is movably connected with the rotating piece 710.

[0049] In order to move the push rod 400 in the vertical direction, an electric cylinder, an oil cylinder, a motor or an air cylinder can be used to drive the movement of the push rod 400. In one of the embodiments, the first driver 100 includes an electric cylinder, which provides power to the push rod 400.
[0050] In other embodiments, the first driver 100 can be an oil cylinder, a motor or an air cylinder.
[0051] In order to make the universal joint 700 move in a straight line in the horizontal direction, the movement of the universal joint 700 can be driven by an electric cylinder, an oil cylinder, an electric motor or an air cylinder.
