Fixing mechanism and motor fault detection equipment

The invention discloses a fixing mechanism and motor fault detection equipment, and belongs to the technical field of motor fault detection. The fixing mechanism comprises a mechanical arm, a first rotating disc, a second rotating disc and a clamping mechanism which are connected in sequence. The first rotating disc and the second rotating disc are sequentially arranged from top to bottom and arerotationally connected. The clamping mechanism comprises a first clamping body and a second clamping body which are oppositely arranged. Each of the first clamping body and the second clamping body comprises a connecting head part and an arc-shaped clamping part connected with the connecting head part. The connecting head is in sliding fit with the second rotating disc. The fixing mechanism facilitates troubleshooting of the end position and observation of the internal condition of a motor, and meanwhile, motor fault detection equipment with the fixing mechanism facilitates troubleshooting ofthe disassembly position o
