Using the above structure, when in use, the driving ball and rubber plug are under the influence of gas along the path of steel pipe
Movement, the driving ball contact with driving wheel and drive driving wheel in indentation, there, and the driving ball can be with the groove of driving wheel
Cooperation;Rubber plug crimp under the promotion of gas, and capable of being bonded with the inner wall of steel pipe, by air seal in steel pipe,
Pressure to generate bigger pushes driving ball movement.
To sum up, the beneficial effects of the utility model are:When automobile collides, generator receives the ECU points of vehicle
Fiery signal, generator detonation, generates the steel ball in gas push steel pipe, while ribbon is recycled, and occupant is reduced to play
The effect of injury, the pre-pressing structure increase rubber plug can better seal gas, to promote preload force value, improve pre-tighten away from
From, and play the role of preferably protecting to driver and occupant when pre-tightening and constraint.
