A nut securing arrangement is provided comprising a nut arrangement and a locking clamp. The opposite sides of the bottom of the nut assembly are provided with a pair of projections, which are formed separately by projections projecting outwards. The retaining bracket comprises a pair of approaches and a pair of receiving channels, wherein the pair of approaches is each arranged at the opposite ends of the retaining bracket and extends in the direction of the nut arrangement, and the pair of receiving channels is configured, to penetrate each pair of approaches,where at least one of the pairs of approaches is an adjustable approach; the adjustable attachment has a locking part and an elastic part; and the distal end of the elastic part is designed so that it is movable under the drive of an external force relative to the distal end of the blocking part, such, that the corresponding projection in the pair of projections can enter through a space between the distal end of the blocking part and the distal end of the elastic part into the corresponding receiving channel,and the protrusion entering the receiving channel can be held by means of the distal end of the elastic part in the receiving channel. In the present application, the nut assembly and the retaining bracket do not tend to separate.
