An oil sealing push groove is provided on the upper end face of the rotating sleeve corresponding to the oil inlet fixing screw hole at the right end, and the sealing push groove can be correspondingly plugged with the plug-in sealing block, a connecting rod is fixedly connected to one side of the inner end of the oil inlet pipe, and a sealing piston is fixedly connected to the upper end face of the connecting rod, and the sealing piston can be correspondingly plugged with the sealing pipe.

[0006] Preferably, the upper end and the left and right ends of the front end surface of the oil delivery pipe are fixedly connected with oil delivery fixing screw holes, and the oil delivery fixing screw holes can be fastened with corresponding bolts of the oil inlet fixing screw holes.

[0007] Preferably, the rotating sleeve is rotatably connected to the front end of the oil inlet pipe.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model provides a temporary blocking device, so that when leakage occurs at the joint, it can be temporarily blocked by simple operation before the arrival of relevant technical personnel, thereby avoiding excessive leakage of substances in the oil pipe and the waste of resources caused. At the same time, it can also avoid some unexpected accidents such as explosions, and the safety of the device is also improved to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS
