description The utility model relates to a cable loosening device for a horizontal clamp of an unmanned crown block, and belongs to the technical field of hoisting equipment. According to the technical scheme, aninner supporting shaft (1) is fixed to a horizontal clamp (9); the support spring inner support guide columns (4) are uniformly distributed on a semicircular arc on one side of the inner support shaft (1); and the alarm plug positive electrode (6) and the alarm plug negative electrode (7) are respectively arranged on the inner walls of the support spring inner support guide columns (4) and the corresponding support spring outer wrapping guide pipes (3). Winding or excessive pulling of the lower-section multi-core cable is reduced through a simple spring structure, an alarm can be given and the rotation of the clamp can be automatically stopped when pulling occurs, so that the problem that the aviation plug is damaged by pulling or the lower-section multi-core cable is broken by pulling issolved, and the problems
