AI Technical Summary
Technical Problem
Existing underground salvage tools can easily cause the mushroom head to be hit and deformed when picking up the underground equipment, and it is inconvenient to disassemble it on the ground after picking up.
Method used
A self-sliding underground fishing tool is designed, which adopts a combination of a fixed mechanism and a positioning mechanism, and uses structures such as hinge plates, sliding plates, trapezoidal parts, and electromagnetic plates to achieve natural lifting and limiting of underground equipment to avoid impacts.
Benefits of technology
It effectively avoids the deformation of the mushroom head of the downhole equipment, simplifies the salvage and removal process of the downhole equipment, and improves the convenience and safety of the operation.

Abstract
The utility model relates to a self-sliding type underground fishing tool which comprises an outer cylinder, a fixing mechanism is arranged on the outer side of the outer cylinder, a positioning mechanism is arranged in the outer cylinder, and an inner cylinder is arranged in the outer cylinder. According to the self-sliding type underground fishing tool, when a mushroom head of a fished underground appliance enters an inner cylinder, two hinge rods on the upper side start to push two hinge plates to start to turn over respectively, so that two trapezoidal pieces on the lower side are clamped into the inner cylinder, and at the moment, two electromagnetic plates make contact with two magnetic attraction blocks respectively and magnetically attract the two magnetic attraction blocks; at the moment, the fished downhole tool can be fished through connection of the hanging ring and an external steel rope, the purposes of naturally jacking the fished downhole tool, conveniently limiting the fished downhole tool and facilitating fishing are achieved, the purpose of preventing the fished downhole tool from being impacted is achieved, and the beneficial effect that a mushroom head of the fished tool is prevented from being hit and deformed is achieved; the problem that a mushroom head of a fished appliance is hit and deformed is solved.
