The rack (25) passes through the mounting bracket (26) and is slidably connected to the rear inner wall of the mounting bracket (26). The rack (25) meshes with the gear (28).

7. The testing method of the strength testing device for motor components according to claim 6, characterized in that, Includes the following steps: S1. First, place the output shaft (3) inside the T-hole; S2, flip the baffle (4) and make the positioning pin (5) engage with the positioning ring (6) so as to position the output shaft (3); S3. Start the drive motor (27) to drive the pressure head component to move downward and apply pressure to the output shaft (3); S4. The pressure sensor (16) can be used to monitor the pressure on the output shaft (3) in real time, so as to accurately measure the maximum bending force that the output shaft (3) can withstand.
