Abstract? The invention relates to a hinge device, which is installed between a cover and a main body of a flip electronic device and has a pivot connected with the cover and a shaft sleeve connected with the main body. The flat part of the shaft sleeve is provided with a butt joint unit, and a concave-convex butt joint part is formed on the butt joint unit to form a positioning effect. The concave-convex arrangement of the butt joint can improve the torque value during positioning, increase the contact point during pivoting, and further increase the stability of pivoting.
