[0029] The limit frame 9 is arranged in a fan shape and the shaft center is consistent with the tensioner body 6;

[0030] The first switch 15 and the second switch 16 are both slidingly clamped to the inner wall of the limit frame 9;

[0031] Among them: the controller 11 is electrically connected with the central control system of the automobile, for timely alarm;

[0032] More preferably, the automatic alarm mechanism is arranged to first hit the first telescopic rod 12 or the second telescopic rod 13 and finally press the first switch 15 or the second switch 16 to trigger the alarm 8 to issue an alarm when the belt 3 is just about to be wound around the tensioner body 6, so as to timely remind the driver to stop and maintain.
