[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0031] In related technologies, nuts are prone to corrosion under some harsh working conditions, making it difficult to remove the nuts from the bolts, which in turn makes it inconvenient to remove the bolts from the components.

[0032] This embodiment provides a bolt removal device that can forcefully break rusted nuts, facilitating bolt removal.

[0033] Please see Figures 1-3In this embodiment, a bolt removal device includes a cylinder 10, an adjusting rod 20, a cutting rod 30, and a connecting member 40; the end of the cylinder 10 has a limiting ring 11; the adjusting rod 20 is screwed onto the end of the cylinder 10 away from the limiting ring 11; the cutting rod 30 is slidably connected to the cylinder 10; one end of the connecting member 40 is rotatably connected to the adjusting rod 20, and the other end is engaged with the cutting rod 30; wherein, the rotation of the adjusting rod 20 can drive the cutting rod 30 to move into the limiting ring 11.

[0034] By using the technical solution of this embodiment, the cutter bar 30 is pushed into the limiting ring 11 by the adjusting rod 20, which can cut off the rusted nut located in the limiting ring 11, thus facilitating bolt disassembly.

[0035] In this embodiment, the cylinder 10 is constructed as a hollow cylinder. A circular limiting ring 11 is fixedly connected to the right end of the cylinder 10, and the axis of the limiting ring 11 is arranged perpendicular to the axis of the cylinder 10. A threaded hole 12 is provided at the end of the cylinder 10 away from the limiting ring 11, and a rectangular hole 13 is provided at the end of the cylinder 10 close to the limiting ring 11. The threaded hole 12 and the rectangular hole 13 are connected. A rectangular clearance opening 14 is also provided on the outer wall of the cylinder 10, and the clearance opening 14 is arranged at the threaded hole 12.

[0036] In this embodiment, the adjusting rod 20 is constructed as a round rod with external threads. The adjusting rod 20 is inserted into the cylinder 10 from the end away from the limiting ring 11 and screwed into the threaded hole 12. A connector 21 is fixedly connected to the inner end of the adjusting rod 20. The connector 21 is constructed as a cylinder arranged coaxially with the adjusting rod 20, and the outer diameter of the connector 21 is smaller than the outer diameter of the adjusting rod 20. An annular groove 22 is provided on the connector 21, and the annular groove 22 is arranged coaxially with the adjusting rod 20.

[0037] In this embodiment, the cutter bar 30 is constructed in a rectangular shape. The cutter bar 30 is inserted into the rectangular hole 13 in a way that fits the shape of the cutter bar 30 and can slide along the extension direction of the rectangular hole 13. A slot 31 is provided on the side wall of the cutter bar 30 facing the relief opening 14. The slot 31 extends along the axial direction of the cylinder 10 and passes through the end of the cutter bar 30 near the adjusting rod 20. A positioning groove 32 is provided at the bottom of the slot 31.

[0038] In this embodiment, the connector 40 is constructed as a rectangular plate. The connector 40 is fitted into the slot 31 with a suitable shape, and the connector 40 does not protrude from the slot 31 to ensure that the connector 40 can move into the rectangular hole 13 along with the cutter bar 30. An arc plate 41 is fixedly connected to the left end of the connector 40, and the arc plate 41 is constructed as a minor arc. The arc plate 41 is coaxially arranged with the adjusting rod 20 and is fitted into the arc groove 22 with a suitable shape. A rectangular positioning plate 42 is fixedly connected to the right end of the connector 40 and is fitted into the positioning groove 32 with a suitable shape. The connector 40 can move into the cylinder 10 from the clearance opening 14 and complete the connection with the adjusting rod 20 and the cutter bar 30, thereby connecting the adjusting rod 20 and the cutter bar 30 into one unit.

[0039] It should be noted that the connector 40 is detachably connected to both the adjusting rod 20 and the tool holder 30, making the connection and disassembly of the adjusting rod 20 and the tool holder 30 easier.

[0040] In use, first place the limiting ring 11 on the outside of the rusted nut, then rotate the adjusting rod 20 to push the cutter bar 30 toward the nut. As the adjusting rod 20 is continuously rotated, the cutter head of the cutter bar 30 forms a cut on the outer wall of the nut, and the cut is parallel to the axis of the nut, until the nut is forcefully cut off. After the nut is cut off and removed, it will be easier to remove the bolt from the component.

[0041] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
