Dragging, butting and adjusting device for forming cylinder body of 3D printer

The utility model discloses a 3D printer forming cylinder dragging butt joint adjusting device which comprises a sleeve frame, the bottom of the sleeve frame is fixedly connected with foot stools, the foot stools are symmetrically arranged, the inner side of the sleeve frame is fixedly connected with a forming cylinder, and a forming chamber is matched with a lifting ring to be lifted to an insertion hole in the inner side of a foot pad to be connected with a first screw rod. Then, according to the position deviation between the forming chamber and the forming cylinder, a second screw rod is rotated to drive a contact on one side of the bearing to move towards the forming chamber, foot pads with the inner diameter larger than the outer diameter of the first screw rod are matched, all corner positions of the forming chamber are pushed, fine position adjustment is carried out, and after the forming chamber is finely adjusted to the needed position, the forming cylinder is driven to rotate; nuts are in threaded
