This utility model relates to the field of optocoupler lead cutting technology, and in particular to an optocoupler de-adhesive cutting and lead-removing block. By setting a relief surface with a specific projection relationship at the bottom of the upper cavity, when the optocoupler is raised due to impurities, the inclined or arc-shaped structure of the relief surface changes the contact point between the lead pin and the lead-removing block from vertical shearing to progressive contact.
