Then, the rotating sleeve rod connected to the fixed column on one side of the rotating disk pulls the extension rod to move as it rotates, and then the rotating sleeve rod at the other end of the extension rod rotates along the outer circumference of the connecting rod. As it rotates, the connecting column connected to the limit block on one side of the connecting rod moves along the limit ring connected to the mounting rod on one side of the support plate, so that the soaking drum can move up and down without rotating, and the internal metal parts are shaken, which effectively prevents the uneven blackening phenomenon.

[0015] In order to protect workers, the metal parts blackening treatment device effectively prevents the immersion drum from being separated by providing a protective cover. The cover plate is pressed down so that the two rotating sleeve rods connected to it rotate along the outer circumference of the fixed rod, so that the cover plate covers the opening of the protective cover.
