The utility model relates to a to drawing screw rod sleeve pipe and a stencil assembly. Wherein, include sleeve pipe body and second supporting part to drawing the screw rod sleeve pipe, the sleeve pipe body includes first supporting part and is the pipe shaft portion of round platform form, and first supporting part is connected with the major diameter end of pipe shaft portion, first supportingpart and the integrated into one piece of pipe shaft portion, and the external diameter of first supporting part is unchangeable or crescent to its free end from its link, and the external diameter oflink is not less than the external diameter of the major diameter end of pipe shaft portion, and the minor diameter of sleeve pipe body is held to dismantle and is connected with the second supporting part that is the round platform and describes. Through respectively dismouting sleeve pipe body and second supporting part, can simplify drawing screw rod sleeve pipe dismouting process, simultaneously, be the round platform form to drawing pipe shaft portion and second supporting part in the screw rod sleeve pipe, first supporting part is set to from its external diameter unchangeable or crescent from the link to the free end, and the external diameter of link is not less than the external diameter of the major diameter end of pipe shaft portion, does benefit to to break away from in drawing screw rod sleeve pipe follow wall body.
