As the application range of stainless steel bars is becoming more and more extensive, such as the foundation of high-rise buildings in cold areas, isolation nets beside highways, household items, etc., the hot rolling production of stainless steel bars has been greatly developed. Clamping is required when processing the outer surface of stainless steel bars.

[0003] After searching, the utility model patent with announcement number CN218254054U discloses a clamping device for stainless steel rod processing, including an equipment base, a moving block is symmetrically installed on the upper end of the equipment base, a screw is installed on the upper end of the moving block, a clamping roller is rotatably installed on the upper end of the moving block and on the screw, two rubber blocks are symmetrically installed on the clamping roller, a fixed structure is installed on the clamping roller, the fixed structure includes a base ring and a fixed column, there are four fixed columns and they are symmetrically installed on the lower end of the base ring, a limiting structure is installed on the screw and above the fixed structure, the limiting structure includes a nut and a limiting plate, the limiting plate is installed on the outer wall of the nut, by arranging the rubber block, because the rubber block is soft in texture, the stainless steel rod that is clamped and limited can be protected, thereby avoiding direct contact and friction between the clamping roller and the stainless steel rod, and finally reducing the probability of the stainless steel rod being scratched or crushed; by arranging the fixed structure and the limiting structure, the rubber block can be easily disassembled and replaced quickly.

[0004] However, the above patents still have the following shortcomings: when adjusting the position of the stainless steel bar, the user needs to manually adjust the displacement of the stainless steel bar between the clamping rollers, which is not convenient; and it is not convenient to adjust the processing surface of the stainless steel bar. For this reason, we propose a clamping and positioning tool for processing the outer surface of steel bars. Utility Model Content
