Belt mechanism for belt tensioner and belt tensioner

A belt mechanism for a belt tensioner, comprising a clamping component and a fixing component;

• the clamping component comprises a clamping frame, a clamping torsion spring, and a clamping body;
• the clamping frame is rotatably connected to a driving arm of the belt tensioner;
• one end of the clamping torsion spring abuts against the clamping frame;
• the clamping body is fixedly provided at one end of the clamping frame;
• when the clamping component clamps and fixes excess webbing, the clamping body clamps and fixes the excess webbing to the belt tensioner;
• the fixing component comprises two fixing rods, the fixing rods are slidably fitted with the driving arm of the belt tensioner;
• the clamping frame is rotated away from the driving arm of the belt tensioner to a first position;
• when the clamping torsion spring drives the clamping frame to rotate towards the driving arm of the belt tensioner, and the clamping frame is at a second position, the fixing rods abut against the clamping frame so as to prevent the clamping frame from resetting.
