[0031] The pumping mechanism comprises a reciprocating screw rod 21, which is rotatably connected in the pumping box 2. The screw rod 21 is threadedly connected with a screw rod sleeve 22. The outer side of the screw rod sleeve 22 is jointly provided with a piston 24 through a plurality of connecting columns 23.
