Preferably, the screw head is internally provided with a standard plum blossom groove of the screw, and the standard plum blossom groove is in a hollow plum blossom shape.
Preferably, the two end ports of the second elastic slot are zigzag.
Preferably, the outer diameter of one end of the screw rod contacting the screw head is smaller than the outer diameter of the other end of the screw rod.
Compared with the prior art, the beneficial effects of the utility model are that: this self-locking screw, the one end of screw head and the one end welding of screw rod, the surface of screw rod is provided with the screw thread, screw rod and screw head looks welded position are provided with second elasticity grooving, second elasticity grooving is located the perpendicular intersection of the welding department of screw head and first elasticity grooving, the both ends port of second elasticity grooving is the zigzag, the one end external diameter of screw rod contact is less than the other end external diameter of screw rod, then the screw rod is inside to be hollowed out, be equipped with first elasticity grooving and second elasticity grooving, make the screw rod have elasticity, when locking matched with hole screw thread like this. Can utilize elasticity to carry out the auto-lock to the port of second elasticity grooving is the cockscomb structure, and dual fixed is easily loosened, and the inside of screw head is provided with screw standard plum blossom groove, and effectual messenger installation space reduces.
