TECHNICAL FIELD The present invention belongs to the technical field of sunshade umbrellas, and specifically relates to an outdoor sunshade umbrella with an umbrella column lifting structure. BACKGROUND As an outdoor leisure appliance, sunshade umbrellas are widely used in leisure venues such as squares, beaches, parks, and courtyards, providing people with comfortable places for leisure and cooling. In the prior art, the Chinese patent with Publication No. “CN211632046U” discloses a Roman umbrella, which includes a stand column, a base, a diagonal rod, two pull rods, and an umbrella body. The stand column is sleeved on the base, one end of the diagonal rod is hinged to a sliding block, the diagonal rod is in sliding connection with the stand column through the sliding block, the other end of the diagonal rod is hinged to the top of the umbrella body, one end of each of the two pull rods is hinged to the top of the stand column, and the other end of each of the two pull rods is hinged to a middle portion of the diagonal rod. According to the sunshade umbrella in the above patent, a single stand column is provided, and an umbrella face is supported by the stand column. By adopting this connection method, the height of the umbrella face cannot be adjusted, and the needs of customers for multi-scenario application cannot be met. Meanwhile, in the process of opening the umbrella face, a range of motion of umbrella ribs is small, and a path for opening the umbrella is single. Therefore, the umbrella is prone to colliding with people or being blocked by obstacles, and cannot be adjusted according to the usage environments, obstacles or people. SUMMARY To make up for the deficiencies of the prior art, the present invention provides an outdoor sunshade umbrella with an umbrella column lifting structure, so as to solve a technical problem that the sunshade umbrella is easily affected by external factors such as environments, obstacles or people when being opened.

The umbrella column assembly includes an upper umbrella column and a lower umbrella column. The upper umbrella column and the lower umbrella column are in sliding fit and have a lifting adjustment mechanism arranged therebetween. The lifting adjustment mechanism is configured to implement ascending or descending of the upper umbrella column relative to the lower umbrella column and can be locked at any height. The umbrella frame assembly is mounted on the upper umbrella column and can be ascended or descended under driving of the upper umbrella column. The upper umbrella column is provided with an armrest shell assembly in a matched manner. The armrest shell assembly is slidably connected to the upper umbrella column and can be locked at any position. The armrest shell assembly can control opening and closing of the umbrella frame assembly during sliding. Further, the lifting adjustment mechanism includes an adjusting assembly and a lifting driving assembly. The adjusting assembly includes a mounting base, a screw rod, and a receiving part. The mounting base is fixed on the upper umbrella column. The screw rod is rotatably connected to the mounting base and can rotate under driving of the lifting driving assembly. The receiving part is fixed on the lower umbrella column and is in threaded fit with the screw rod. Further, the lifting driving assembly includes a transmission rod, a connecting member, and a first bevel gear and a second bevel gear that are meshed with each other.
