A button-type commemorative medal and its rotatable multifunctional mechanism structure, wherein pressing the button lever drives the slide bar to move, the slide bar drives the rack to move and stretches the first spring, thereby causing the rack to drive the meshing gear to rotate, causing the first gear to rotate the rotating shaft, which in turn drives the cover plate to rotate, allowing the user to change the display content of the commemorative medal through operation, displaying the second pattern through the through hole, thereby increasing the interactivity and viewing experience of the commemorative medal and enhancing the fun of playing with it. The provided storage seat can be used to place small items such as small photos and commemorative coins. The transparent protective cover not only provides protection but also allows people to clearly see the items inside, increasing the functionality of the commemorative medal. At the same time, the transparent protective cover is rotated to slide along the guide groove. When the through hole and the transparent protective cover are aligned, the elastic force of the second spring pushes the fixed seat and the storage seat upward, causing the storage seat and the transparent protective cover to extend out of the cover plate through the through hole, thereby making it convenient for people to view the small objects placed in the storage seat. The commemorative medal has multiple functions such as rotating display of patterns and storage of small items, greatly enhancing the value and appeal of the commemorative medal.

[0016] 2. This button-type commemorative medallion and its rotatable multifunctional mechanism structure rotates the connecting rod by rotating the cover plate, which in turn drives the ring gear to rotate. The ring gear drives the meshing gear 2 to rotate, which in turn drives the rotating rod to rotate. The rotating rod drives the mounting plate and the pattern 3 thereon to rotate, exposing the pattern 3 from the bottom of the base for display, thus realizing the rotating display of multiple layers of patterns, greatly enriching the display effect of the commemorative medallion and increasing its ornamental value and interest.

[0017] 3. This button-type commemorative medal and its rotatable multifunctional mechanism structure effectively reduce the friction of the cover when sliding in the inner cavity of the base through the provided ball bearings, making the sliding of the cover smoother, reducing wear and tear, and extending the service life of the commemorative medal. The provided oil filling hole allows users to add lubricant to the slide groove regularly, further reducing friction and maintaining the smooth operation of the various components of the commemorative medal. The provided sealing bolt blocks the oil filling hole, thereby enhancing the sealing of the slide groove and avoiding leakage of internal lubricant. At the same time, it can also prevent dust and other impurities from entering the slide groove, ensuring the lubrication effect.

[0018] 4. This button-type commemorative medal and its rotatable multifunctional mechanism structure can be conveniently hung on a key chain, backpack or display stand through the provided hanging legs and hanging holes. It is easy to carry and can be displayed as a decoration, which increases the usage scenarios of the commemorative medal. BRIEF DESCRIPTION OF THE DRAWINGS
