Embodiment Construction

[0007] A leather book corner with adjustable self-weight is characterized in that: it includes two folds with a certain thickness of leather combined to form a right angle, and there are organic folds perpendicular to the folds at the inner corners of the folds. As for the glass adjusting sheet, there is a vertical protrusion on the inner contact surface of the folding leaf, and the corresponding position on the adjusting sheet is provided with a slot, and the protrusion can be snapped into the slot. All the protrusions are inverted trapezoids.

[0008] The beneficial effect of the invention is that the structure is very simple and practical. have a certain weight. The adjustment 1 can be stuck to the inner corner of the folding leaf because of its certain viscosity, and the distance below the adjustment sheet is adjusted according to the thickness of the book, so as to enclose books with a certain thickness such as dictionaries and ancient books.
