Positioning device for oxygen and acetylene cylinder transportation

The positioning device comprises an arc-shaped frame, a bottom plate and universal wheels, the two sides of the bottom of the arc-shaped frame are fixedly connected with the two sides of the top of the bottom plate, the left sides of the two sides of the bottom of the bottom plate are fixedly connected with the tops of the universal wheels, and the two sides of the left side of the inner wall of the arc-shaped frame are fixedly connected with limiting sleeves. According to the oxygen and acetylene cylinder fixing device, the arc-shaped limiting rods are arranged, the ends, away from the limiting sleeves, of the arc-shaped limiting rods are inserted into the connecting sleeves, oxygen and acetylene cylinders on the arc-shaped frames are limited, and the oxygen and acetylene cylinders are fixed by utilizing the advantage that the arc-shaped limiting rods are integrally hard; by arranging the arc-shaped limiting rods, the arc-shaped limiting rods cannot collide with the oxygen and acetylene cylinders in the proc
