• the first support leg and/or the second support leg has a square-shaped section;
• the second support leg is provided with a torsion spring sleeve so that the second support leg is inserted into the corresponding sleeve holes;
• the torsion spring sleeve has a square outline, the bottom of which relatively moves along the arc-shaped stressed portion on the two sides of the hinging arm under the force applied by the torsion spring, thus generating opening force or closing force.
