A kind of rotational structure of Electric burning pen, main system is comprising pen body and sets the cutter head of what pen body, scalable Smoking pipe, and combines the rotating member of what pen body end, is pivotally connected the conduit of the what rotating member. Wherein, which is equipped with an articulated section, which includes within can relatively rotating, outer ring body, so that rotating member is nested with the articulated section of what pen body, and conduit is made to be nested with the outer rim of what rotating member outer ring body. In order to work as Electric burning pen what in use, be able to make Smoking pipe by the rotating member and conduit be in relative to rotation, and then Electric burning pen is enable freely to rotate, with the operation of sharp what Electric burning pen.一種電燒筆之轉動結構,主要係包含筆身及設於筆身之刀頭、可伸縮之吸煙管,以及結合於筆身末端之轉動件、樞接於該轉動件之導管。其中,該筆身末端係設有一樞接部,該轉動件係包含可相對轉動之內、外圈體,使轉動件套置於筆身之樞接部,且使導管套置於轉動件外圈體的外緣。俾當電燒筆於使用時,得以藉由該轉動件使吸煙管與導管呈相對之轉動,進而使電燒筆得以自由的轉動,以利於電燒筆的操作。
