The invention discloses a bottle clamp, which comprises a clamp opening matched with a bottle nozzle, wherein a plurality of reinforcing ribs are arranged at the inner side of the clamp opening; one end of each reinforcing rib is connected with the inner wall of the bottle clamp, and the other end of each reinforcing rib is connected with the periphery of the clamp opening. The reinforcing ribs are added to the inner side of the clamp opening, so that the strength of the frequently used clamp opening of the bottle clamp is enhanced, and the service life of the bottle clamp is improved by five times.
