Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1 and Figure 2 As shown, the utility model provides a universal tool for pulling out a bearing seat, comprising a hydraulic jack 1 and a bearing seat 2, a seat disassembly tool 3 is arranged between the hydraulic jack 1 and the bearing seat 2, and one side of the seat disassembly tool 3 is threadedly connected to the outer surface of the hydraulic jack 1, and the other side of the seat disassembly tool 3 is fixedly connected with a connecting flange 4, and the surface of the connecting flange 4 is connected to the bearing seat 2 through a clamping assembly, and three clamping assemblies are arranged, and a torsion bar 5 is assembled inside the bearing seat 2, and the torsion bar 5 passes through one side of the inside of the seat disassembly tool 3 and is fixedly connected with a torsion bar end 6, and a threaded protective sleeve 7 is sleeved on one side of the torsion bar end 6, and the seat disassembly tool 3 is arranged in a sleeve shape.

[0025] Through the arrangement of the above structure, after the seat disassembly tool 3 is connected to the bearing seat 2, the hydraulic pump is pressurized until the seat component is separated from the torsion bar, so that the bearing seat 2 is easily pulled out.
