A one-button powder box opening mechanism was designed. By setting a movable pressing part and an elastic part on the lid, the lid can be opened and the drawer can be pushed out with a one-button press. When closed, it is automatically pushed back into the drawer cavity. The structure is simple and easy to operate with one hand.
It allows for opening the lid and extending the drawer with a single button operation, and automatically returns the drawer to its original position when closed, making it easy to operate and suitable for one-handed use.
