The invention belongs to the technical field of clamping structures in vegetable-washing devices, and especially relates to a novel clamping structure for vegetable washing. The novel clamping structure for vegetable washing comprises an upper clamping unit arranged in a washing frame, a clamping ring unit arranged on the upper clamping unit, and a clamping control unit for controlling clamping and taking-out of ball-shaped vegetables; and a lower clamping unit for clamping lower parts of the ball-shaped vegetables is arranged below the clamping ring unit. The novel clamping structure for vegetable washing is capable of effectively fixing the ball-shaped vegetables one by one for washing, so that influence to the appearance integrities of the vegetables caused by collision is avoided. The invention has the following advantages: the novel clamping structure for vegetable washing is simple and effective in structure, convenient and rapid for fixing and taking-out the ball-shaped vegetables, good in washing effects, and high in vegetable appearance protection levels.
