[0002] Prestressed steel strands, as a high-strength and high-toughness building material, are widely used in the construction of large-scale infrastructure projects such as highways, railway bridges, high-rise buildings, and water conservancy projects. Their role in engineering is crucial; they not only require precise length dimensions but also surface grinding and rust removal to ensure strong connections and uniform stress distribution during tensioning, anchoring, and other construction phases, thereby guaranteeing the overall safety and stability of the engineering structure.

[0003] Based on the above, the inventors have discovered the following problems: the current integrated cutting and grinding machine for prestressed steel strands is difficult to grind and cut steel strands of different diameters, resulting in low versatility and affecting user experience.

[0009] Furthermore, the second adjustment mechanism includes a second bidirectional threaded rod, the top and bottom ends of which are rotatably connected to the inner top and bottom ends of the second upright, respectively.
