AI Technical Summary
Technical Problem
Existing simulated Christmas trees cause the tree to rise when the base area is reduced by rotating the legs, raising the center of gravity and affecting stability.
Method used
Design a simulated Christmas tree that uses a liftable notched gear and rack structure. The rotation and lifting of the legs are controlled by a manual drive device to adjust the support area. The lower end of the legs is lowered to compensate for the rise of the lower end, keeping the height of the lower end of the legs constant.
Benefits of technology
It allows for adjustment of the support area based on the tree's height, reducing space occupation while maintaining the Christmas tree's stability, not affecting the center of gravity, and improving ease of use.

Abstract
The utility model relates to the technical field of Christmas trees, in particular to a simulation Christmas tree which comprises a tree body, a lower cover, an upper cover, a cylinder and three supporting legs, the outer wall of the lower cover, the outer wall of the cylinder and the outer wall of the upper cover are each provided with three inserting grooves in a circumferential array, and U-shaped groove plates are welded in the inserting grooves. Notch gears capable of ascending and descending are matched with racks to control supporting legs to rotate and stretch, so that the supporting area can be adjusted according to the height of a tree body, the placing area is reduced, the supporting legs can be completely retracted into U-shaped groove plates, and the storage space is reduced; the lower end rises relative to the upper end due to rotation is compensated through downward movement of the upper end of the supporting leg, so that the height of the lower end of the supporting leg is kept unchanged, the height and the gravity center of the Christmas tree cannot be affected, and stability is kept.
