[0002] Metal heat treatment is a process in which a metal workpiece is heated to a suitable temperature in a certain medium, kept at this temperature for a certain period of time, and then cooled at different speeds in different media to control its performance by changing the surface or internal microstructure of the metal material.

[0003] For example, a cooling mechanism for heat treatment of metal parts disclosed in a Chinese patent document (Announcement No.: CN215209546U) "comprises a fixed box, characterized in that: a driving motor is fixedly installed inside the fixed box, and a reducer located above the driving motor is fixedly installed inside the fixed box, a connecting shaft is fixedly sleeved above the output shaft of the driving motor, the top end of the connecting shaft extends to the top of the fixed box and a turntable is fixedly installed, a guide plate located below the turntable is fixedly installed above the fixed box, and electric telescopic columns located on both sides of the turntable are fixedly installed on the top of the fixed box, a telescopic rod is movably sleeved inside the electric telescopic column, a movable column is fixedly installed at the end of the telescopic rod, a cooling hood is fixedly installed at the end of the movable column, a spray base is fixedly sleeved inside the cooling hood, a refrigeration unit is fixedly installed on the back of the fixed box, and a cooling pipe is fixedly connected between the refrigeration unit and the spray base."

[0004] Although the above-mentioned existing cooling mechanism for heat treatment of metal parts has achieved the effect of "through the coordinated use of the driving motor and the connecting shaft as well as the turntable and the cooling cover, the cooling mechanism for heat treatment of metal parts can place the metal parts to be cooled above the turntable, and then the two cooling covers wrap the metal parts under the coordinated use of the electric telescopic column and the telescopic rod, and then the cooling water is injected into the inside of the spray base through the refrigeration unit and the cooling pipe, so that the metal parts located inside the cooling cover are quickly cooled, and at the same time, the driving motor drives the turntable to rotate slowly through the connecting shaft, so that the cooling effect of the metal parts is more uniform", the existing cooling mechanism for heat treatment of metal parts has the following problems after the metal parts are placed above the turntable due to the lack of the fixing function of the metal parts:

[0005] Instability: Since the metal parts are not fixed on the turntable, but simply placed on it, when the drive motor of the existing cooling mechanism for heat treatment of metal parts drives the turntable to rotate through the connecting shaft, the metal parts are prone to move or shake on the turntable, resulting in instability during the cooling process, which in turn easily affects the cooling effect;

[0006] Uneven cooling: Since the metal parts are not fixed in one position, the position of the metal parts will change during the cooling process, resulting in uneven cooling, and some areas will be affected by over-cooling or under-cooling. Utility Model Content
