摘要

The fishing rod (1) is fastened to a support frame (2). A mounting (6''c) on the frame member (2a) nearest the tip of the rod carries a pivot (6'c) with a horizontal axis (A). A horizontal rod (6a) attached to this pivot carries a tilt switch (7) with a LED (Light Emitting Diode) (10) connected (11,12a) with a battery box (8). The rod carries a weight (6b) near the end remote from the first pivot. An extension rod (6d) is connected to a second pivot on a horizontal axis (B). A clip (6'd) on a swivel mounting (6''d) pulls the fishing line (4) out of a straight line. A tug on the line can cause the clip to slip. The weighted rod then drops, a contact in the tilt switch is made, and the LED glows.
