Wellhead detachment auxiliary tool

The utility model relates to a wellhead detachment auxiliary tool, and belongs to the technical field of connecting and detachment tools of wellhead flow process of oilfield producing wells or oil collecting valve assemblies. The tool consists of an adjusting cylinder, a first adjusting rod and a second adjusting rod, wherein the adjusting cylinder is in a pipe shape, the two sides of the center line of the adjusting cylinder are provided with inner threads, the inner threads comprise right-hand threads at one side and left hand threads at the other side, the two adjusting rods are respectively in an L shape, and respectively consist of a screw rod and a clamping ring, each clamping ring is welded at one end of each screw rod, and the adjusting rods are arranged at the two sides of the adjusting cylinder through the self screw rod. When the tool is used, the tool is clamped between two adjacent oil pipelines of the wellhead of an oilfield producing well, the distance between the two adjacent pipelines is adjusted through rotating the adjusting cylinder, and then the deformed and dislocated pipelines are centered and aligned, so a wellhead connecting pipe can be conveniently detached and installed, the labor strength is reduced, and the working efficiency is improved.
