[0003] A Chinese patent discloses a maintenance and testing platform for aircraft crew seats (authorization announcement number CN 210942305U). The patented technology can fix the crew seat on a test platform through a positioning clamp, a clamp body and a limit rod. No personnel assistance is required when repairing and testing the crew seat, which reduces the number of operators and reduces labor costs. The platform is connected to the base through a telescopic cylinder, so the platform can be placed horizontally on the base or vertically on one side of the base, which is easy to access and operate, and facilitates the maintenance and testing of various parts on the crew seat. However, the device has a weak clamping force on the aircraft crew seat when in use, and a low separation and adjustment force between the seat back and the seat cushion, which reduces the maintenance and testing efficiency of the aircraft crew seat and causes a waste of time and human resources.
