The rotating mechanism 300 is connected to the part to be tested, allowing the rotating mechanism 300 to rotate and stretch the part. The synchronous belt mechanism 400 is used to control the up and down movement of the telescopic group 210. In order to enable the synchronous belt mechanism 400 to control the up and down movement of the telescopic group 210, this application, through the above settings, allows the rotating mechanism to rotate repeatedly while also moving up and down, repeatedly stretching, and testing the service life of the part.
