The utility model provides a this pressure equipment is put, including cleanness portion, cleanness portion sets up on the supporting part, and the length direction that can follow the supporting part eradicates the residual that attaches to the supporting part upper surface, adopts eradicant clean mode promptly, and rapid removal compares in the current artifical manual scheme of getting rid of the residual of cleaning attached to the intractable residual of supporting part upper surface, and clean effect is better, and is clean efficient, labour saving and time saving, and then improve product yield and equipment utilization ratio.
