Abstract

The utility model relates to a safety belt clamping structure. The safety belt clamping structure is arranged at one side of a safety belt retractor of an automobile and is connected with a shaft rod of the safety belt retractor. The safety belt clamping structure comprises a shell, an actuating component and a stopping component which are arranged in the shell, wherein the shell is provided with a supporting seat at the position of the bottom of an inner space thereof so as to lead a steel ball of the stopping component to be arranged on the supporting seat and then the swinging clamping rod is used for pressing on the steel ball in a butting manner, wherein a through punched hole is formed on the supporting seat, and an opening is formed at the bottom end of the shell. By means of the design, when mud sand or sandy dust enters the clamping structure, the mud sand can be naturally discharged out of the clamping structure by the punched hole at the bottom end of the supporting seat and the opening at the bottom end of the shell, so that the mud sand or the sandy dust is avoided being deposited in the supporting seat to influence the due moving function of the steel ball, and the safe actuation of the clamping structure can be ensured.
