Connecting structure of single-screw machine

The utility model belongs to the technical field of single-screw machines, and particularly relates to a connecting structure of a single-screw machine, which comprises a mounting fixture block, a mounting seat is clamped on the outer side of the mounting fixture block, a guide groove is arranged on the mounting seat, a screw is fixedly connected onto the mounting seat, a fixing plate is fixedly connected onto the mounting fixture block, and the fixing plate is fixedly connected onto the mounting fixture block. A limiting block is fixedly connected to the fixing plate, a limiting block is slidably connected to the interior of the guide groove, and a nut is fixedly connected to the mounting base. By arranging parts such as the fixing plate and the limiting block, the mounting clamping block can be limited leftwards and rightwards when the mounting clamping block is connected with the mounting seat, so that the mounting clamping block cannot move leftwards and rightwards, and by arranging the screw and the nut,
