[0021] The present invention has the following beneficial effects:

[0022] When the present invention places the motor to be tested into the interior of the testing frame, the connection between the electric push rod and the pull rod pushes the top cover to move upwardly from the testing frame. When the top cover is separated from the top of the testing frame, the motor is placed in the clamping frame to contact with the supporting component, and the supporting component is used to support and limit the motor, thereby improving the convenience of the motor during clamping and disassembly. When the supporting component drives the motor to move downwardly from the clamping frame, the supporting component pushes the clamping component to clamp and fix the motor, thereby avoiding shaking of the motor during noise detection, resulting in errors in the detection results. At the same time, the supporting component pushes the extrusion component to extrude the clamping component, thereby further improving the stability of the clamping component when fixing the motor. After the motor is fixed inside the clamping frame, the top cover contacts the inner wall of the testing frame through the electric push rod. At this time, the motor is started to rotate, and the noise generated by the motor is detected using a noise detector. Placing the motor inside the testing frame can avoid the influence of external sounds on the detection of motor noise.

[0023] After the motor is placed inside the clamping frame, the bottom of the motor will contact the top of the supporting plate, and the driving motor is started to drive the rotating rod to rotate. When the rotating rod rotates, the driving ring drives the driving ring to rotate inside the clamping frame through the rotating frame, and the gear drives the threaded rod to rotate inside the groove plate by meshing with the driving ring. The moving block pulls the bottom of the push plate toward the outer end of the clamping frame by the rotation of the threaded rod, so that the support plate is pushed to move downward of the clamping frame by the push plate, and the motor is limited by the inner wall of the clamping frame to avoid the motor from tilting during noise detection, resulting in unstable operation of the motor, thereby further improving the stability of the motor during noise detection.

[0024] When the support plate of the present invention moves downward, it pushes the force-bearing plate to move. When the force-bearing plate moves, it pushes the top of the clamping rod to move toward the inside of the clamping frame through the spring sheet. When the clamping rod moves, it pushes the protective frame to move toward the surface of the motor through the elastic rod. The protective frame pushes the rubber block to squeeze and clamp the motor through the pressure of the clamping rod, thereby improving the stability of the motor when working and avoiding the error in the detection result of the noise detector caused by the noise generated by vibration when the motor is working.

[0025] When the moving block of the present invention moves, the lifting frame is pushed upward by the elastic telescopic rod, and the lifting frame moves on the surface of the slide plate, thereby improving the stability of the lifting frame when squeezing the pressure plate. When the lifting frame moves, the pressure plate is pushed by the bent plate to squeeze the clamping rod, thereby increasing the strength of the clamping rod to clamp and fix the motor, further improving the stability of the motor when working.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the support plate 26 moves downward, it pushes the force plate 35 to move. When moving, the force plate 35 pushes the top of the clamping rod 37 to move toward the inside of the clamping frame 10 through the spring sheet 32, and the clamping rod 37 pushes the protective frame 36 toward the motor through the elastic rod 33 when moving. The protective frame 36 pushes the rubber block 34 to squeeze and clamp the motor through the pressure of the clamping rod 37, thereby improving the stability of the motor during operation and preventing the motor from generating noise due to vibration during operation, which may cause errors in the detection results of the noise detector 13. When moving, the moving block 22 pushes the lifting frame 44 to move upward through the elastic telescopic rod 43, and the lifting frame 44 moves on the surface of the slide plate 46 to improve the stability of the lifting frame 44 when squeezing the pressure plate 47.
