A button with a torsion spring is hinged to the pressure plate, forming a press-to-unlock structure. When in use, the button is pressed to open the locking structure of the pressure plate and the hook. The buckle ring can be taken off and put on. When the button is released, the pressure plate and the hook are locked by the torsion spring. The operation is very quick and convenient. It is easy to adjust under the condition of tension of the leg ring. The wearing efficiency is high, and the comfort performance of the safety belt leg ring is improved.
