[0003] A surface hardness detection device for die metal products disclosed in the Chinese utility model patent application CN207964526U includes a base, a detection table, a pressing rod, and a hard pressing head. Both sides of the upper end of the base are welded with side frames. The upper end of the base is installed with a detection table through bottom columns. The inner bottom end of the side frame is installed with a driving motor. The output end of the driving motor is connected to the bottom end of a rotating disk. A threaded column is welded above the rotating disk. A fixing block is sleeved outside the threaded column. One side of the fixing block is welded with a pressing rod. The upper end of the side frame is welded with a top seat. The middle of the bottom end of the top seat is fixedly welded with a lifting column. The bottom end of the lifting column is fixedly welded with a hard pressing head. By setting structures such as a threaded column, a fixing block, a pressing rod, a driving motor, and a rotating disk, the function of pressing and fixing is realized to prevent it from slipping.
