Abstract
Disclosed is a center pole fixing structure, including a center pole and a base. The base is provided with a center hole. The center pole is inserted into the center hole to be fixed. An anti-disengagement fixing structure is formed between the center pole and the base, achieves fixing by relative rotation of the center pole and the base, and constrains movement of the center pole in an axial direction thereof. A stopper for constraining the rotation of the center pole is disposed between the center pole and the base. The stopper is a movable pin, and the movable pin is controlled to enter or exit, thereby locking or unlocking the relative rotation of the center pole and the base. According to the disclosure, the center pole and the base are convenient to mount and dismount, and the fixed structure is firm and stable.
Claims19
