When the extrusion ring 6 contacts the support frame 5, the support frame 5 is squeezed and drives the single-beam depth sounder 3 to swing outward around the pin shaft inside the connecting block 4. Multiple single-beam depth sounders 3 maintain the same swing angle, so as to achieve the effect of expanding the measurement area.
