When the nut is used, the nut body is embedded into the through hole correspondingly connected, then the screw or the bolt is screwed into the nut body, and the connecting part is contracted by extruding the connecting part through the through hole of the connecting piece due to the fact that the connecting part is provided with the cutting groove, so that the screw or the bolt is fastened.
Preferably, the nut seat and the connecting part are integrally formed by injection molding.
Preferably, the inner side wall of the connecting part is provided with an internal thread for connecting with a bolt or a screw.
Preferably, the number of the cutting grooves is 2, and two cutting grooves are symmetrically arranged on the connecting part.
Preferably, the nut seat is circular, and a plurality of bumps are uniformly distributed on the outer side wall of the nut seat along the circumference, the bumps are of a conical structure, and the stability of the connection between the nut and the connecting piece is further improved through the bumps.
The utility model has the advantages that:
1. the utility model has simple structure and strong practicability, and avoids the falling off of the nut by mutually matching the nut body and the connecting piece;
2. the utility model discloses an offer the grooving along vertical direction on connecting portion, through extrusion connecting portion to make connecting portion tighten up clamping screw or bolt, thereby prevent the problem that nut or bolt that leads to because the vibration drops.
