[0082] The spanwise adjustment washer compensation measure intersection structure is used to adjust the installation tolerance between the first link 1, the second link 2, the third link 3, and the fourth link 4 closed loop and the wing fixed structure 13. There are 17 intersections in the whole set of motion mechanisms, and only the K intersection needs to be manually adjusted according to the actual gap. The adjustment method is as follows:
