A downhole multi-purpose integrated fishing tool

Abstract

The utility model relates to the technical field of fishing tool, concretely to a downhole multipurpose integrated fishing tool, including connecting cylinder, the inside installation of connecting cylinder has the baffle, and the bottom surface middle position department of baffle installs motor, the output fixedly connected with the rotating lever of motor, and the fixed installation of rotating lever has second helical gear on, the inside both sides of connecting cylinder are equipped with screw rod. Through starting the motor drive rotating lever of baffle bottom, the second helical gear on rotating lever drives the synchronous rotation of first helical gear on screw rod, because threaded cylinder realizes axial location through the cooperation of limiting block and limiting groove, the rotation of screw rod will force threaded cylinder to move along screw rod axial, thereby promotes the guiding wheel to stretch outwards, when guiding wheel and well wall contact, can provide stable radial support and guiding effect in the process of lowering, effectively prevent fishing tool from sticking with well wall because of deflection, promote the stability and reliability of the lowering of tool, ensure the smooth implementation of fishing operation.
