[0021] Specifically, the fastener 30 comprises a first housing 31 and a special-shaped column 32, the special-shaped column 32 is internally provided with a containing cavity 321, a first tooth ring 322 is fixedly installed on the cavity wall of the containing cavity 321, a first spring 33 is fixedly connected between the connecting shaft 41 and the bottom surface of the containing cavity 321, a second tooth ring 411 is fixedly installed on the connecting shaft 41, and the first tooth ring 322 is in meshing connection with the second tooth ring 411.

[0022] When it is needed to adjust the pitch angle position of the bracket rod 40, an operator presses the first pressing block 43, so that the connecting shaft 41 is axially moved to the inside of the fastener 30 against the elastic force of the first spring 33, the action drives the second tooth ring 411 to be disengaged from the meshing state with the first tooth ring 322, and the locking is released, at this time, the bracket rod 40 is in a free adjustment state, the connecting shaft 41 can rotate in the first shaft hole 21, the first sliding pin 42 slides along the first adjustment slot 22, and the bracket rod 40 is guided to move along a preset track, and a user can manually rotate the bracket rod 40 to a required angle.

[0023] After adjustment, the first pressing block 43 is released, the connecting shaft 41 is pushed back to the original position under the action of the elastic force of the first spring 33, the second tooth ring 411 is re-engaged with the first tooth ring 322, rigid locking is formed, and since the tooth ring engagement has high contact area and shear resistance, the cable gravity, vibration or external force impact can be effectively resisted, and displacement or loosening of the bracket rod 40 is prevented.

[0024] In order to realize stepless adjustment of the bracket rod 40, further, a first limiting table 323 is fixedly installed on the cavity wall of the containing cavity 321, and a non-slip pad 324 is fixedly installed on the opposite surface of the first limiting table 323 and the second tooth ring 411.
