[0002] In modern manufacturing industry, metal heat treatment is a crucial process link, and is widely used in aerospace, automobile manufacturing, machining, energy and many other fields. Its purpose is to accurately control the structure and performance of metal through a series of operations such as heating, heat preservation and cooling of metal materials, so as to meet the strict use requirements of various complex engineering parts.

[0003] In view of the above problems, the patent with publication number CN221051943U discloses a clamp for metal heat treatment, which comprises a base and two support frames. The upper surface of the base is provided with lifting lugs, the support frames are symmetrically arranged on the top left side of the base and are symmetrically arranged front and back, a plurality of support pieces are symmetrically arranged on the left and right sides of the support frame, the support frame is in triangular structure, a plurality of moving blocks are symmetrically arranged on the bottom left and right sides of the support frame, and a plurality of rollers are rotatably connected to the bottom of the moving blocks. A sliding groove is formed in the top of the base and is in sliding connection with the corresponding left and right rollers. A support rod is arranged on the top of the base between the front and back of the two support frames, and a cross bar is arranged between the top of the support rod. However, the above structure does not take into account the radial size of the shaft tool. When processing shaft workpieces with large radial size, it is difficult for the fixed support piece to support the shaft. When the radial size of the shaft workpiece is small, it is difficult for the fixed support piece to fix the shaft workpiece. If there is a bump during heat treatment, the shaft workpiece will shake, thereby affecting the heat treatment effect. When processing disc workpieces, the patent uses a rotating bidirectional screw to push the clamp to clamp the disc workpiece. If the operator is not skilled or applies too much force, the clamp will be damaged when clamping, and the shape of the disc workpiece will be damaged during hot processing. UTILITY MODEL CONTENTS
