When the loosening barrel assembly 50 is disassembled, the abutting frame body 295 is pulled outwards, so that the abutting rod is separated from the supporting bent plate 282, the supporting bent plate 282 drives the two arc-shaped engaging plates 2825 to ascend under the action of the pressure spring to support the two discs 51, the penetrating barrel 292 moves outwards to be separated from the overturning round cover 271, so that the overturning round cover 271 can be overturned out and is perpendicular to the supporting plate 22, and the driving shaft which is just pulled out can be conveniently supported because the penetrating barrel 292 is not arranged in the arc-shaped supporting groove 2255 on the overturning round cover 271. The surface of the seal circular plate 2715 is adapted to be aligned with the top surface of the arc plate 53 positioned lowermost therein so that the drive shaft can smoothly slide onto the arc support groove 2255. The rigid frame 29 can support the supporting bent plate 282 to separate from the two circular discs 51, and can position the circular discs 51, facilitate fixing the sealing circular plate 2715, and facilitate injecting lubricating oil, thereby achieving multiple purposes.
