Rapid extraction device

Abstract

The invention belongs to the field of extraction devices, and particularly relates to a rapid extraction device which comprises a first extractor and a second extractor, a first connecting pipe is arranged on the first extractor, a second connecting pipe is arranged on the second extractor, and the first connecting pipe is in contact with the second connecting pipe. By designing a rotating rod, a rotating block, a rotating ring, a first bearing, a first bevel gear, a second bevel gear and other components, the rotating rod is rotated to drive the positive and negative screw rod and other components to rotate, the positive and negative screw rod rotates to make threaded motion with a threaded sleeve, and then the semicircular sealing sleeve and other components move; after the semicircular sealing sleeve moves to make contact with the first extractor and the second extractor, the joint of the first extractor and the cover body and the joint of the second extractor and the cover body are sealed, and liquid in the device is prevented from leaking from the joint of the first extractor and the cover body and the joint of the second extractor and the cover body.
