Kind Code:
B2
Abstract:
An unconventional bolt comprises a main body (52) having two heads (521), and two threaded rods (51) respectively formed at the external surface of each head (521) coaxially with the main body (52), wherein the cross section of each head (521) has a noncircular shape, and the axial projection of the cross section of the middle of the main body (52) is located in the noncircular axial projection of each head (521) of the main body (52). The unconventional bolt (5) has a simple structure and a convenient assembly, and can improve the strength and rigidity of the nested profiled components after the connection; and the fastening device using the unconventional bolt (5) can not only support the component but also reinforce it, thus effectively preventing the nested profiled components from transforming.
