The telescopic end of the telescopic cylinder 5 is rotatably connected to the turntable 42, that is, when the turntable 42 rotates, the telescopic end of the telescopic cylinder 5 rotates relatively to the telescopic end of the telescopic cylinder 5, and the telescopic end of the telescopic cylinder 5 is fixed. The support arm 43 of the turntable 42 is connected with the loosening motor 6, the loosening motor 6 is connected with the buckle head 61, the buckle head 61 can be buckled and connected with the nut 211 of the locking bolt 21, and after the buckle head 61 is buckled on the nut 211, the loosening and tightening operation of the nut 211 can be realized by forward and reverse rotation of the loosening motor 6.
Principle of operation: as shown in fig. 5, it is assumed that the flange port 11 and the cover 2 are connected by 6 lock bolts 21. When the device is normally used, the control system controls the adjusting motor 4 to periodically start and rotate to drive the buckling head 61 to be in butt joint with the first nut 211a, then the telescopic cylinder 5 is started to enable the buckling head 61 to be buckled on the first nut 211a, and finally the loosening motor 6 starts to rotate positively and negatively to loosen (i.e. loosen the nut first and then tighten the nut) the first nut 211 a.
