A stretching device for extrusion blow molded products mainly solves technical problems such as improving product strength. The technical solution adopted is that a stretching mechanism capable of reciprocating movement parallel to the center line of the die head is arranged on the blow molding machine body on one side of the die head. A moving frame of the stretching mechanism is connected with a tensioning and clamping mechanism for tensioning and holding the blow molded parison. The center line of the tensioning and clamping assembly of the tensioning and clamping mechanism is collinear with the center line of the die head. It is suitable for various extrusion blow molding operations.
