[0037] The adjusting member 202 includes a support block 202a arranged on the upper surface of the upper plate 102 for supporting the vertical motor, a connecting wheel 202b arranged at one end of the support block 202a for cooperating with the first rack 202c to drive the support block 202a to expand or contract following the rotation of the rotating ring 201, the first rack 202c arranged on the inner wall of the rotating ring 201 and meshing with the connecting wheel 202b, the connecting shaft 202d arranged at the center of the connecting wheel 202b for cooperating with the first shaft hole 202e to enable the support block 202a to rotate, and the first shaft hole 202e arranged on the connecting wheel 202b and cooperating with the connecting shaft 202d to fix the position of the cover plate 105.

[0038] The support block 202a has an overall arc shape that matches the inner diameter of the upper plate 102, and when the vertical motor to be repaired does not need to be supported by the support block 202a, the support block 202a can be completely retracted into the upper plate 102 and the cover plate 105 to avoid affecting the personnel repair.

[0039] In use, when the outer diameter of the vertical motor to be repaired is smaller than the inner diameter of the cover plate 105, the power assembly 300 is started to drive the rotating ring 201 to rotate, the first rack 202c drives the support block 202a to rotate to the center of the cover plate 105 through the connecting wheel 202b, and the support block 202a is locked in the position when the power assembly 300 is stopped. When all the repair work is completed, the rotating ring 201 is reversed by the power assembly 300 to drive the support block 202a to retract, and the support block 202a is completely retracted into the upper plate 102 and the cover plate 105 when the support block 202a contacts the abutting block 203.
