The invention discloses a clip structure for preventing a vehicle safety belt from being too tight. The structure comprises an upper clip, a middle clip, a lower clip, a pin, a torsional spring, a lug boss, a silica-gel head, a safety belt and the like, and that is to say, the twisting force of the torsional spring is adopted to fixedly clamping the safety belt which is installed between the upper clip and the lower clip, so that the safety belt cannot slide optionally. The structure has the advantages that the structure aims at achieving the purpose that drivers and passengers can adjust the tightness degree of safety belts on bodies at any time to feel more comfortable when the drivers and the passengers fasten the safety belts, clothes are effectively prevented from abrasion caused by the repeated friction between the clothes and the safety belts, and various potential safety hazards are effectively alleviated, wherein the potential safety hazards are harmful to safe driving and caused by too tight vehicle safety belts. Meanwhile, the structure is very simple in structure, very low in cost, suitable for the installation and usage of various safety belts, and conductive to vigorous promotion.
