[0044] Working principle: If the rotating speed of the motor 3 is to be tested, the rotating disc 4 is fixed on the output end of the motor 3, and then the motor 3 is started. The motor 3 drives the rotating disc 4 to rotate. In the process of rotation, the protrusions 17 in the annular groove 5 also rotate. When the protrusions 17 pass the top block 6, the top block 6 is lifted upward, and the top block 6 extrudes the spring 7 under the action of the fixed plate 9, so that the spring 7 deforms and generates elastic force. When the top block 6 is lifted upward, the sliding column 8 fixedly connected with the top block 6 moves upward and touches the counter 10, and the counter 10 records the number of collisions with the sliding column 8. When the protrusions 17 rotate away from the top block 6, the top block 6 moves downward into the annular groove 5 under the action of the elastic force of the spring 7, and at this time, the sliding column 8 is away from the counter 10. Therefore, when the motor 3 rotates one round, the sliding column 8 touches the counter 10 once, so that the number of revolutions of the rotating disc 4 within a certain time can be calculated according to the number of collisions recorded by the counter 10, and the rotating speed of the motor 3 can be calculated, that is, the measurement of the rotating speed of the motor 3 can be realized, which reduces manual intervention, saves time and effort, has high working efficiency, and avoids the problem of inaccurate measurement of the rotating speed of the motor caused by human error.

[0045] Before measurement, the motor 3 needs to be fixed, so the telescopic rods 201 are started. When the two telescopic rods 201 are extended, the two clamping blocks 206 are brought close to each other through the two sliding rods 202, so that the two clamping blocks 206 clamp and fix the motor 3, which is firm and can avoid the problem that the motor easily shakes during the measurement of the rotating speed of the motor, thereby ensuring the accuracy of the measurement result and guaranteeing the final test result of the motor.
