The utility model has the center of the detonating device and the centers of obstacle one and obstacle two on the same horizontal plane. After the airbag is installed on the detonating device and detonated, the airbag first contacts obstacle one and obstacle two and then contacts the detection component. Obstacle one simulates an obstacle with an arc shape, and obstacle two simulates the boundary of the obstacle, so as to avoid deviation between the airbag test and the actual situation and ensure the accuracy of the test.

[0026] There are a total of multiple carrying components 3. The staff will press down the handheld carrying components 3 one by one.

When there are only a few support components 3 left on the left side of the pipe 22, the gooseneck rod 27 is directly removed from the limit sleeve 26 and the operating sleeve 28 is held. Then, the several support components 3 on the left side of the soapy water 23 are pushed downward through the bottom end of the gooseneck rod 27 until the last support component 3 moves to the right side of the pipe 22. When the device operation is completed, the device is restored.
