Multi-angle locked-rotor locking mechanism for testing electric drive assembly

The invention discloses a multi-angle locked-rotor locking mechanism for testing an electric drive assembly, which is characterized in that a locked-rotor assembly is arranged on a base, a brake assembly is matched with the locked-rotor assembly, a through hole is formed in the locked-rotor assembly, the base or a clutch assembly is in sliding fit with a slide rail, a driver is connected with the base or the locked-rotor assembly or the clutch assembly, and the brake assembly is matched with the locked-rotor assembly. The locked-rotor assembly and the clutch assembly are combined or separated under the driving force of the driver, the locking assembly is connected with the base or the clutch assembly, the locking assembly is matched with the sliding rail, and the locked-rotor assembly surrounds the clutch assembly; the clutch assembly comprises a first coupling assembly, a second coupling assembly and a driven disc used for being combined with or separated from a through hole of the locked-rotor assembly, the
