Single-screw long pump structure

The utility model relates to the technical field of long pump structures, in particular to a single-screw long pump structure which comprises a connecting frame, a driving box is fixedly installed at one end of the connecting frame, a main screw is fixedly installed in the driving box, a connecting sleeve is fixedly installed at one end of the main screw, and an auxiliary screw is fixedly installed at one end of the connecting sleeve. The screw has the advantages that the main screw and the auxiliary screw are connected through the connecting sleeve, the driving box drives the main screw to rotate, the main screw drives the auxiliary screw to rotate synchronously through the connecting sleeve, and the connecting sleeve rotates synchronously along with the main screw; media transmitted by the main screw rod are transmitted to the auxiliary screw rod through the threads on the surface of the connecting sleeve, the transmission effect on the media is achieved, then the screw rods can be effectively disassembled,
