[0048] In this embodiment, the lower end of the threaded rod 4 is fixedly connected with the anti-escape handle 8 with a larger diameter than the threaded sleeve 5. By fixing the anti-escape handle 8 with a larger diameter than the threaded sleeve 5 at the lower end of the threaded rod 4, it can prevent the threaded rod 4 from being excessively rotated and embedded in the threaded sleeve 5 and the connecting sleeve 7, so that the threaded rod 4 cannot be rotated. At the same time, the anti-escape handle 8 can also facilitate the worker to rotate the threaded rod 4 during installation.

[0049] Example Seven

[0050] In combination Figure 5 As shown in some optional embodiments, the vertical angle steel further comprises a vertical end 101 and a horizontal end 102, the end of the vertical end 101 is provided with a first round corner 1011, the end of the horizontal end 102 is provided with a second round corner 1021, and the vertical end 101 and the horizontal end 102 are integrally formed.

[0060] In the embodiment, the third round corner 103 can be provided at the right-angled corner of the vertical end 101 and the horizontal end 102. Since the right-angled corner is the position for connecting the vertical angle steel 1 with the horizontal angle steel 2 and the connecting square steel 6, stress concentration occurs at this position, and cracks and fractures are prone to occur under stress. The design of the third round corner 103 can make the stress distribution more uniform, reduce the stress concentration phenomenon, thereby improving the overall strength and carrying capacity of the connection, and prolonging the service life of the overall support frame.

The height adjusting mechanism is fixedly connected with the fiber distribution box 3, and can freely adjust the height of the fiber distribution box 3 on the support formed by the horizontal angle steel 2 and the vertical angle steel 1, so as to achieve the purpose that the fiber distribution box 3 can freely adjust the height to the installation position formed by the horizontal angle steel 2 and the vertical angle steel 1, and reduce the installation difficulty of the fiber distribution box 3. At the same time, since the fiber distribution box support is composed of the vertical angle steel 1 and the horizontal angle steel 2, the support structure is simple and occupies small space, and the installation is convenient, only the bottom of the vertical angle steel 1 needs to be fixed, so that the installation of the fiber distribution box 3 is no longer limited to the areas such as the outer wall of the house, the enclosing wall and the communication pole, and can be directly installed in the public area such as the green belt, so that the site selection is more flexible and the installation is simple.
