Next, a locking support of the flag pole 300 according to the present exemplary embodiment will be further described.

In some embodiments of the present application, the locking nut base 100 is provided with an internal threaded hole 101, and the internal threaded hole 101 is axially penetrating through the locking nut base 100, so that one end of the locking nut base 100 is inserted into the flag pole 300, and the other end of the locking nut base 100 can be screwed into the locking screw pole 200. The locking screw rod 200 is provided with an external thread 201, the external thread 201 is matched with an internal thread of the internal threaded hole 101, and the internal threaded hole 101 is tapered, so that the locking screw rod 200 is screwed into the locking nut seat 100 more tightly, thereby improving the locking force and preventing easy loosening. The locking screw rod 200 is provided with a locking hole 202 along the axial direction thereof, when the locking screw rod 200 is screwed into the locking nut seat 100, the locking hole 202 is communicated with the internal threaded hole 101, wherein the screwing direction of the locking screw rod 200 is consistent with the tapering direction of the internal threaded hole 101, namely, when the flagpole 300 is inserted from one end of the locking nut seat 100, the locking screw rod 200 can be directly inserted into the locking hole 202 of the locking screw rod 200, and the screwing direction of the locking screw rod 200 is the tapering direction of the internal threaded hole 101, so that the locking screw rod 200 is increasingly tightened with the flagpole 300 in the screwing process, and is locked and fixed; the screw-in end of the locking screw rod 200 is cut with at least one slit 203 along the axial direction thereof to form an elastic locking portion 204, and after being screwed into the locking nut seat 100, the elastic locking portion 204 is tightly locked on the flag pole 300 under the extrusion of the tapered internal threaded hole 101, thereby increasing the locking force.

As a preferred embodiment, one end of the locking screw shaft 200 is a hexagonal screw head, and the other end of the locking screw shaft 200 is extended with a tapered portion 205, wherein the slit 203 of the locking screw shaft 200 is simultaneously extended to the tapered portion 205.
