[0042] The specific operation mode of the utility model is as follows:

[0043] First, when the body controller is placed on the test platform 10, the body controller contacts the pressure sensor 70. The pressure sensor 70 senses the pressure and transmits a signal to the tester 20. After receiving the signal, the controller in the tester 20 automatically starts the electric push rod 33 and the servo motor 41 to operate. The operation of the electric push rod 33 makes the movable block 32 approach the body controller to position the body controller. The operation of the servo motor 41 makes the screw rod 42 rotate, and then the L-shaped nut block 43 drives the movable frame 44 and the data plug 50 toward one end of the body controller until the data plug 50 is inserted into the data interface of the body controller, completing the electrical connection between the body controller and the tester 20, and then the test can be carried out. After the test is completed, the servo motor 41 and the electric push rod 33 operate in the opposite direction again to complete the removal of the data plug 50 and release the fixation of the body controller.
