[0015] To better understand the above technical solutions, exemplary embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.

[0016] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1 like Figure 2 , Figure 3 , Figure 5As shown, this embodiment includes a solid centering rod 10. Since the existing centering rod is a hollow structure, it is prone to wear during use and needs to be replaced frequently. At the same time, there are no auxiliary disassembly tools, and it is easy to break during disassembly. However, the application makes the centering rod more durable by setting a solid centering rod 10, and the sleeve 20 (described in detail below) can further prevent the centering rod thread 12 (described in detail below) from breaking.

[0019] The solid centering rod 10 includes a rod body 11, a centering rod thread 12 on the first end of the rod body 11, and a first slot 13 on the second end of the rod body 11. The centering rod thread 12 and the rod body 11 are integral, and the major diameter of the centering rod thread 12 is smaller than the diameter of the rod body 11. In this embodiment, the centering rod thread 12 and the rod body 11 are integral. Thus, the centering rod thread 12 is used to connect with the equipment centering device. The first slot 13 facilitates the disassembly of the solid centering rod 10 by the operator using a wrench. Furthermore, by engaging the wrench with the first slot 13, the solid centering rod can be easily disassembled, avoiding damage to the threads due to uneven force.

[0020] In this embodiment, a second slot is provided on the second end of the rod body 11. The second slot and the first slot 13 are symmetrically arranged on the second end of the rod body 11. This further facilitates the use of a wrench to clamp the second slot and the first slot 13 to disassemble the solid centering rod 10. At the same time, the setting of the second slot effectively increases the stability of the wrench clamping, prevents slippage, and ensures that the disassembly process is safe and efficient.

[0021] In this embodiment, the symmetrical layout of the second slot and the first slot 13 makes the force more even and avoids deformation of the rod or damage to the threads due to force on one side.

[0022] A sleeve 20 is fitted onto the solid centering rod 10, and the sleeve 20 and the solid centering rod 10 are in clearance fit; thus, the sleeve 20 ensures that the solid centering rod 10 will not shake during disassembly, which would cause the solid centering rod 10 to break.

[0023] In this embodiment, the sleeve 20 is provided with a sleeve thread 21, which is used to connect with the equipment drive chuck; thereby achieving a stable connection between the sleeve 20 and the equipment drive chuck, and avoiding damage to the centering rod thread when disassembling.

[0024] The sleeve 20 is also equipped with a screwing block 22, which facilitates manual tightening or disassembly and improves the ease of operation; after the sleeve thread 21 is connected to the equipment drive chuck, the screwing block facilitates the application of torque, making the overall installation more stable.

[0025] In this embodiment, the outer diameter of the screwing block 22 is larger than the major diameter of the sleeve thread 21; thus, by setting the screwing block 22, the sleeve 20 can be easily disassembled from the solid centering rod 10; at the same time, during the installation process, the screwing block 22 applies force to make the sleeve thread 21 reliably engage with the equipment drive chuck.

[0026] Example 2 like Figure 2 , Figure 4 , Figure 5 As shown, this embodiment includes a solid centering rod 10. Since the existing centering rod is a hollow structure, it is prone to wear during use and needs to be replaced frequently. At the same time, there are no auxiliary disassembly tools, and it is easy to break during disassembly. However, the application makes the centering rod more durable by setting a solid centering rod 10, and the sleeve 20 (described in detail below) can further prevent the centering rod thread 12 (described in detail below) from breaking.

[0027] The solid centering rod 10 includes a rod body 11, a centering rod thread 12 on the first end of the rod body 11, and a first slot 13 on the second end of the rod body 11. The centering rod thread 12 and the rod body 11 are integral, and the major diameter of the centering rod thread 12 is smaller than the diameter of the rod body 11. In this embodiment, the centering rod thread 12 and the rod body 11 are integral. Thus, the centering rod thread 12 is used to connect with the equipment centering device. The first slot 13 facilitates the disassembly of the solid centering rod 10 by the operator using a wrench. Furthermore, by engaging the wrench with the first slot 13, the solid centering rod can be easily disassembled, avoiding damage to the threads due to uneven force.

[0028] In this embodiment, a second slot is provided on the second end of the rod body 11. The second slot is offset from the first slot 13 and is provided on the second end of the rod body 11. Thus, the second slot allows the wrench to apply force from different angles, further improving the disassembly flexibility and stability. When the first slot 13 is worn, the second slot can serve as a backup force point, extending the service life of the solid centering rod.

[0029] A sleeve 20 is fitted onto the solid centering rod 10, and the sleeve 20 and the solid centering rod 10 are in clearance fit; thus, the sleeve 20 ensures that the solid centering rod 10 will not shake during disassembly, which would cause the solid centering rod 10 to break.

[0030] In this embodiment, the sleeve 20 is provided with a sleeve thread 21, which is used to connect with the equipment drive chuck; thereby achieving a stable connection between the sleeve 20 and the equipment drive chuck, and avoiding damage to the centering rod thread when disassembling.

[0031] The sleeve 20 is also equipped with a screwing block 22, which facilitates manual tightening or disassembly and improves the ease of operation; after the sleeve thread 21 is connected to the equipment drive chuck, the screwing block facilitates the application of torque, making the overall installation more stable.

[0032] In this embodiment, the diameter of the screwing block 22 is larger than the major diameter of the sleeve thread 21; thus, by setting the screwing block 22, the sleeve 20 can be easily disassembled from the solid centering rod 10; at the same time, during the installation process, the screwing block 22 applies force to make the sleeve thread 21 reliably engage with the equipment drive chuck.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
