The utility model relates to a bore hole pump cylinder liner screw thread circle handling instrument, the inner wall welding of cylinder steel ring has six can block the bellied jack catch of bore hole pump cylinder liner screw thread circle periphery respectively, and each jack catch shape size is the same and follow same circumference evenly distributed, and each jack catch all lies in the axial middle part of cylinder steel ring inner wall, and the welding has the axis of outwardly directed handle, the axis perpendicular to cylinder steel ring of handle on the outer wall of cylinder steel ring. Be equipped with the U-shaped recess on the jack catch respectively, the shape size of each U-shaped recess respectively with the bellied shape of bore hole pump cylinder liner screw thread circle periphery size looks adaptation, the opening of each U-shaped recess is respectively towards the tangential direction of cylinder steel ring. The opening position of each U-shaped recess is equipped with the horn mouth that outer imperial palace is little respectively. This instrument can not followed the screw thread and circled and drop, does not need other people supplementary construction, and the operator's operation of being convenient for reduces operating personnel's potential safety hazard to bore hole pump cylinder liner screw thread circle is done benefit to by the tangential force and produces the rotation.
