Embodiment Construction

[0008] The content of the technical solution is described in detail in conjunction with the accompanying drawings.

[0009] Assembly and working order: Connect the internal thread of the connecting plate 3 with the external thread of the hub 2, seat the jack 5 in the base 8 (the base 8 is a concave-shaped original tray with 2 holes on it), and pass 2 pull rods 4 (the pull rods 4 is cylindrical, there are two milled planes in the middle, the purpose is to use a wrench during installation to avoid slipping, and both ends have internal threads), connect the base 8, the jack 5 and the connecting plate 3, and tighten them with the washer 6 and the bolt 7 Fixed, so that the connecting disc 3, the wheel hub 2, the base 8, and the pull rod 4 have become a whole. Then turn on the manual hydraulic station 1 to press the jack 5. The piston part of the jack 5 starts to work and slowly stretches out. When it contacts the hub 2, continue to press the jack 5. Using the principle of action fo...
