The existing patent, patent announcement number CN214243496U, discloses a high-strength inner lifting arm, whose structure includes an arm body, a fixed joint groove is provided at one end of the arm body, and a rotating groove is provided at the other end. A gear ring is sleeved in the fixed joint groove, and a rotating positioning sleeve is provided in the rotating groove. An even number of limit blocks are equidistantly provided on the outer ring of the gear ring. A limit groove corresponding to the limit block is provided on the inner wall of the fixed joint groove, and an assembly groove communicating with the two limit grooves at the same time is provided on the outer wall of the fixed joint groove. The gear ring is made of high-strength cemented carbide material, has strong deformation resistance, and effectively improves the service life. If the tooth block structure in the gear ring is damaged, the fixing bolts at both ends of the fixed plate can be screwed out to release the displacement restriction of the limit block. The limit block plays a role in positioning and strengthening the linkage coordination between the gear ring and the fixed joint groove. The staff takes out the damaged gear ring for replacement by tools, and there is no need to replace the entire inner lifting arm, thereby reducing the output cost.
