[0025] As shown in Figure 1 , Figure 5 The lower end of the first oscillator is sequentially connected to the fishing tool main body, the second oscillator and the bottom cone, the fishing tool main body is a cylindrical structure, and the middle part of the fishing tool main body is provided with a semi-hollow receiving groove, this design not only guarantees the strength, but also facilitates the installation and cooperation of other components, the fishing arm 13 is arranged in the semi-hollow receiving groove, the fishing arm lock wheel 12 is arranged on the fishing tool main body, and the fishing arm lock wheel 12 controls the opening and closing state of the fishing arm 13, this design makes the fishing tool open the fishing arm when needed, and effectively performs fishing operation; A plurality of strong magnetic sheets 16 are arranged in the groove, the strong magnetic sheets 16 are uniformly distributed at the bottom of the semi-hollow receiving groove in the middle part of the fishing tool main body, and the semi-hollow receiving groove in the middle part of the fishing tool main body is provided with a spring, this design makes the fishing arm 13 have certain elastic recovery force when opened, thereby improving the efficiency of fishing operation, the four-way joint is arranged at the front end of the fishing arm 13, the anti-falling sheath 14 is sleeved on the outer wall of the four-way joint of the fishing arm 13, the front end of the anti-falling sheath 14 is provided with a compression spring, the compression spring is sleeved on the joint 15, and the compression spring limits the anti-falling sheath 14, this design ensures that the screw connected with the joint 15 and the four-way joint will not be pulled out in the vibration process, thereby improving the reliability of the whole system.

[0026] AsFigure 4 As shown, the middle part of the bottom cone is a semi-hollow receiving groove, which not only ensures the strength of the bottom cone, but also facilitates the installation and cooperation of other components. The semi-hollow receiving groove in the middle part of the bottom cone is provided with a spring, which enables the positioning claw 18 to have a certain elastic restoring force when it is opened, thereby improving its adaptability and stability in complex downhole environments.
