Liquid flow stop clamp

The invention relates to a liquid flow stop clamp which is provided with a liquid flow stop clamp body. The liquid flow stop clamp body comprises an elastic support and a body fixing frame. An elastic locking flange structure is arranged on the lower portion of the elastic support. A body locking flange structure is arranged on the inner side of the body fixing frame. The free end of the body fixing frame is provided with a first opening through which an infusion tube penetrates. A second opening through which the infusion tube penetrates is arranged at the joint of the body fixing frame and the elastic support. According to the liquid flow stop clamp, the body fixing frame and the elastic support are provided with openings though which the infusion tube can directly penetrate from outside to inside, and in the actual production process, the phenomenon that the infusion tube is inserted into the liquid flow stop clamp before machining is finished is avoided, so that the production and installation efficiency of the liquid flow stop clamp is effectively improved, and the labor cost is reduced.
