[0024] After the aircraft landing gear model is vertically lifted upward by the lifting lifting device 2, the adapter part at the top of the aircraft landing gear model can be inserted into the adapter part of the landing gear top adapter 6, and the adapter part at the top of the drive rod (a telescopic rod used to drive the aircraft landing gear model to overturn and adjust) of the aircraft landing gear model can be overturned to the adapter part of the landing gear drive rod adapter 7, and an external adapter pin shaft is inserted and installed between the two to realize hoisting.

[0025] It should be noted that the C-shaped frame body 1 is fixedly installed with a fixed plate 12, the lifting lifting device 2 comprises a table plate 21 fixedly installed in the C-shaped frame body 1, a threaded rod 22 rotatably installed between the table plate 21 and the fixed plate 12, two directional rods 23 fixedly installed between the table plate 21 and the C-shaped frame body 1, a servo motor 24 fixedly installed on the upper surface of the table plate 21, the output end of the servo motor 24 is fixedly connected with the top end of the threaded rod 22 through a shaft coupling, a lifting platform 25 is screwed on the outer surface of the threaded rod 22, the lifting platform 25 is slidingly installed between the two directional rods 23, and a bracket 26 is fixedly installed on the front surface of the lifting platform 25, a bracket groove 261 is formed in the upper surface of the bracket 26;

[0026] The servo motor 24 is a pulse forward and reverse motor, which is connected with an external controller for use, the external controller controls the forward rotation or reverse rotation of the servo motor 24 by sending a pulse signal to the servo motor 24, and after the servo motor 24 is started, the threaded rod 22 can be driven to rotate forward or reverse, thereby driving the lifting platform 25 and the bracket 26 to lift.

[0027] When using the lifting device 2 to lift the aircraft landing gear model, after placing the cross beam between the two wheel bodies of the aircraft landing gear model into the trough 261 of the bracket 26, use the limiting device 3 to clamp and fix the vertical axis perpendicular to the cross beam on the aircraft landing gear model. After keeping the vertical fixation of the aircraft landing gear model, use the servo motor 24 to drive the rotation of the threaded rod 22, drive the lifting platform 25 to move upward, and then use the bracket 26 to lift the entire aircraft landing gear model upward to a suitable installation position below the lifting plate 5.
