[0030] As Figures 6-8As shown, according to another embodiment of the present utility model, the special-shaped bag cylinder welding machine further optimizes the fixing member, transmission member, clamping member and operating member it includes. The fixing member includes a fixing plate 3 fixedly connected to the side of the support portion away from the base 1. The fixing plate 3 is horizontally arranged, and a rotating groove 31 is formed at the bottom of the fixing plate 3.
