The conventional pump pipe 6 is arranged inside the shell 1, and the pump pipe 6 has certain limitation on the volume and the length, so that the utility model ensures that the suction force generated when the single negative pressure rod 7 works is strong enough by arranging the pump pipe 6 externally, thereby avoiding sucking the focus for many times and relieving the pain of the patient; when the negative pressure buckle 8 is pressed down, the negative pressure rod 7 is ejected forwards by the contact end to drive the L-shaped sealing ring 10 to move simultaneously, so that air is sucked into the pump pipe 6.

Because the pump pipe 6 needs to generate negative pressure continuously when in use, the ventilation part 4 comprises the air pipe 11, the one-way valve 12 and the inner pipe limiting joint 13, so that air can move towards the direction of the pump pipe 6 only through the one-way valve 12, and the phenomenon of sudden pressure relief in the use process is avoided.
