[0003] In the prior art, the patent application with application number "CN210023613U" has applied for: "A hot-rolled spring processing tooling". This patent drives the adjusting threaded rod to rotate by turning the handle, thereby realizing the movement of the fixed plate. In this way, the steel bars can be firmly fixed and can support each other well to ensure that the shape of the steel bars will not change, thereby greatly ensuring the forming quality of the steel bars, and is worthy of promotion and use.

[0004] However, the steel bar is fixed by turning the handle to adjust the rotation of the threaded rod. After long-term use, it cannot be ensured that the threaded rod will not loosen, thereby affecting the fixation of the steel bar. Utility Model Content

[0006] To achieve the above-mentioned purpose, a hot-rolled spring processing tool is provided, comprising: a fixed plate, a threaded rod is screwed inside the fixed plate, a rotating handle is integrally formed on the top of the threaded rod, and it is characterized in that a limit rod is movably inserted into the surface of the rotating handle, the bottom of the limit rod is movably inserted in a limit groove, and the limit groove is opened at the top of the fixed plate.

[0007] According to a hot-rolled spring processing tooling, the rotating handle is a "cross" shaped plate structure, a movable groove is opened on the surface of the rotating handle, the movable groove is a circular groove structure, and the limit rod is movably inserted in the movable groove, and the limit rod is a "T" shaped column structure.

[0008] According to a hot-rolled spring processing tool, a support spring is arranged between the top of the rotating handle and the limit rod, the support spring is sleeved on the outside of the limit rod, and two groups of limit rods are arranged, and the two groups of limit rods are symmetrically distributed about the center of the rotating handle.

[0009] According to a hot-rolled spring processing tool, a sliding groove is provided on the surface of the limit rod, the sliding groove is an annular groove structure, the surface of the sliding groove is slidably connected to a limit ring, the limit ring is an annular plate structure, and the limit ring is movably inserted in the limit slot, and the limit slot is provided at the bottom of the rotating handle.

[0010] According to a hot-rolled spring processing tool, a rotating opening is opened on the top of the rotating handle, and the rotating opening is a "T"-shaped cylindrical groove. The inner rotation of the rotating opening is connected with a rotating rod, and the rotating rod is a "T"-shaped cylindrical structure.

[0011] According to a hot-rolled spring processing tool, a limiting clamping plate is arranged on the top of the rotating rod, the limiting clamping plate is in a square plate-shaped structure, and the bottom of the limiting clamping plate contacts the top of the limiting rod.

[0012] According to a hot-rolled spring processing tool, the surfaces of the limiting clamping plate in contact with the limiting rod are both provided with damping pads.

[0013] The above scheme has the beneficial effect: under the action of the damping pad, the limit clamping plate and the limit rod will not be easily separated, thereby preventing the bottom of the limit rod from being separated from the limit groove, and the two sets of limit rods can be limited, which plays a role in limiting the threaded rod as a whole, preventing the threaded rod as a whole from loosening during long-term use.
