Among them, the "Injection molding with injection molding positioning structure" disclosed in the application number "CN202021122075.4" The "machine" is also an increasingly mature technology. Insert one end of the hose into the copper storage chamber with a rubber connecting plug on the left, and apply sealant to the contact point between the hose and the rubber connecting plug. Engage the other end of the hose with the small hole on the top of the injection pen, and apply sealant to its engagement point, so that the heated and softened plastic will not flow out of the connection gap due to excessive pressure. Place the injection pen in the middle of the slider, place buckles on the upper and lower ends of the slider, pick up the screw and align the sharper end of the screw with the hole on the upper part of the buckle, rotate clockwise and press down, so that the screw fixes the buckle on the slider, which is not only convenient for the installer to install, but also convenient for replacement when maintenance is needed.
