The shaft tube (5,6) has an incorporated mechanical weighting device (8) with a spring (9), which permanently strives to maintain a component (10) in the shaft, which is withdrawable from it and works in conjunction with a scale. A gainst the effect of the spring, the component can be drawn outwards so that with aid of the scale it can show the weight of the fish suspended in the hook part (2). The hook part is rigidly joined to the shaft (1) and the weighing device is arranged in the end of the shaft opposite to the hook part. The movable and spring-loaded component comprises of a bar (10), which extends outwards through a hole in a gable part (13) of the shaft tube and at a free end a hand-grip part (14) is provided. At the opposite end, is a piston-type component (15), the spring itself is of the pressure type (9), which is positioned between the piston component and the gable part. |
