Fishing-line locking device, fixable to a draw wire for trolling

摘要

Fishing-line locking device fixable to a draw wire for trolling which comprises an easy to grip body (1) having jaw means (2a, 2b) at one of its ends with two opposing locking surfaces and means for fixing the body to the draw wire at the other end. Perpendicular to the locking surfaces, a non rotating through pin (9) is provided whose ends have threading of different pitches, the one with the fine pitch (9b) engaging in a adjustment bushing (10) and the one with the coarse pitch (9c) engaging in tightening means (11) of said jaw means. Reference means (10c, 12) are provided for tightening the jaw means at a pre-established pressure. The device is fixed to the draw wire by means of a groove (13), inside which the draw wire is housed and a slider (14) elastically forcing on the draw wire and is held in a gripping position by a second slider (15) which wedges itself between the first slider (14) and the body (1) of the device. <MATH>
