According to the invention, the first locking piece 1 and the screw 901 are locked and fixed by the design that the flat-cutting groove 121 is arranged on the screw thread of the screw 901 close to the screw head 1001 and the fixture block 131 in the flat-cutting groove is embedded in the inner wall of the first screw through hole 3, so that the first locking piece 1 is prevented from rotating on the screw 901 and is used for screwing the screw 901 and the fastener B, and the phenomenon that the screw 901 is loosened is avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
