The slider 13 and the slide groove 14 can conveniently limit the movable rod 4, thereby preventing the movable rod 4 from deviating when moving. A handle 19 is fixedly connected to the top of the threaded rod 18, and the handle 19 can conveniently drive the threaded rod 18 to rotate when in use.

[0036] Working principle: when the fan 6 is supported and fixed and prevented from tipping over, the motor 20 drives the gear 21 to rotate, and when the gear 21 rotates, it drives the rack plate 1 22 and the rack plate 2 23 to move at the same time, and when the rack plate 1 22 and the rack plate 2 23 move at the same time, they drive the two extension blocks 15 to extend to both sides, and when they extend to the required position, the handle 19 is turned to drive the threaded rod 18 to rotate at the same time, and when the threaded rod 18 rotates, it drives the support block 17 to move downward, thereby preventing the fan from tipping over.

[0037] When the height of the fan 6 needs to be adjusted, the pull rod 8 is pulled to move it. When the pull rod 8 moves, the limit block 9 will be driven to move at the same time. When the limit block 9 moves, the spring 10 will be squeezed. At the same time, the limit block 9 will drive the card block 11 to move, so that the card block 11 is disengaged from the card slot 12. When the card block 11 is disengaged from the card slot 12, the movable rod 4 can be pulled to move, so that the height of the fan 6 can be easily adjusted and locked after adjustment.
