[0036] Working principle of this utility model:

[0037] When the above structure is used, the height of the ground support universal chassis 28 is first adjusted by rotating the ground support hand wheel 29 to balance the entire wooden support platform. Then, the jacking hand wheel 18 is rotated to adjust the lifting screw rod 19 to lift and lower the aircraft without rotating it, so that the lifting male and female heads 10 at the top of the lifting screw rod 19 can lift the aircraft. Finally, by rotating the lifting hand wheel 219, the lifting screw rod 216 can be lifted and lowered to fit the aircraft head to the wooden support 23 to the belly of the aircraft to support the belly of the aircraft, thereby completing the support effect on the aircraft.

[0038] It is worth mentioning that the thrust bearing 12 and the lifting nut 13 of the lifting component and the thrust bearing 20 and the lifting nut 2 17 of the adjustable wooden support structure adopt a sinker gravity bearing with an internal thread and a sliding sleeve design, so that the lifting screw 1 9 and the lifting screw 2 16 can be lifted and lowered smoothly without shaking due to the large gap, so that the lifting screw can be easily turned with one hand when bearing a load of several tons, thereby lifting the aircraft.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
