[0041] In some embodiments, the locking assembly 300 includes a latch pin 330, a tension spring 340, and a third disk 130. A limiting protrusion ring 333 is provided on the latch pin 330. The tension spring 340 is sleeved on the latch pin 330, with one end pressing against the limiting protrusion ring 333 and the other end pressing against the third disk 130. The bottom end of the latch pin 330 passes through the first plug hole 111, the through hole and the second plug hole 121 in sequence.

[0042] By arranging a tension spring 340 on the latch pin 330, one end of the tension spring 340 presses against the limiting convex ring 333 of the latch pin 330, and the other end presses against the third disk 130. It is only necessary to set the tension spring 340 to be in an initial state when the latch pin 330 is inserted into the mounting platform, and the tension spring 340 is in a compressed state when the latch pin 330 rises and leaves the mounting platform. The elastic force of the tension spring 340 itself can be utilized. When in use, the latch pin 330 can be automatically inserted into the first plug hole 111, the through hole and the second plug hole 121 under the elastic force of the tension spring 340, thereby improving the locking convenience and stability of the vertical pole 100 and the horizontal pole 200.
