Mining two-stage pump convenient to fix and move

The invention discloses a mining two-stage pump convenient to fix and move, and belongs to the technical field of mining equipment.The mining two-stage pump comprises a sealing shell composed of a lower protection shell and an upper protection shell, two supports are fixedly installed on the inner wall of the lower protection shell, and a water supply mechanism is fixed to the surfaces of the supports in a penetrating mode; the opposite faces of the two water supply mechanisms are jointly provided with a reciprocating sliding piece, and a sliding rod penetrates through the inner wall of the sliding piece in a sliding mode. According to the mining two-stage pump convenient to fix and move, by arranging a transmission gear, a connecting rod and airtight cylinders, the transmission gear drives a sliding rod to move and keeps driving a sliding piece and the two airtight cylinders to move synchronously, so that when the airtight cylinders slide, the airtight cylinders correspondingly control the pressure change in
