The elastic fastener includes a contact plate 72 and a spring 71 , one end of the spring 71 is integrally connected with the inner wall of the fixing ring 7 , and the free end of the spring 71 is integrally connected with the contact plate 72 . When in use, the water cup is placed on the placing plate 6, and the contact plate 72 is squeezed by the water cup and squeezes the spring 71 in the direction of the fixing ring 7. The action of this force can fix the water cup and effectively prevent the water cup from tipping over. 71 has good elastic deformation ability and can be applied to various types of water cups.

The contact plate 72 is configured as a circular arc-shaped plate. The contact plate 72 arranged in this way can well fit the outer wall of the water cup.

Five of the elastic fasteners are provided. This setting fastens the water cup in multiple directions, effectively preventing the water cup from tipping over.

The description of the above embodiment is only for understanding the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principles of the present utility model, several improvements can also be made to the present utility model, and these improvements will also fall within the protection scope of the claims of the present utility model.
