[0024] The driving member is arranged in the vertical pipe 1 above the supporting cylinder 16 and close to the top plate of the supporting cylinder 16. The driving member includes a bevel gear 24 and a bevel gear 25. The bevel gear 24 is sleeved and fixed outside the worm 11.

One end of the driving rod 26 faces the worm 11 and is connected to the bevel gear 25 meshing with the bevel gear 24.

[0025] A friction pattern 28 is provided on the top plate of the bearing tube 16. The friction pattern 28 is a raised grid-like pattern that is integrated with the bearing tube 16. The friction pattern 28 is made of the same material as the bearing tube. A screw rod 29 is threadedly connected to the rotating plate 23. The lower end of the screw rod 29 is pressed against the friction pattern 28 or away from the friction pattern 28, and the upper end is connected to a rotating plate 30.

[0026] The other end of the driving rod 26 is located outside the vertical pipe 1 and is connected to a second rotating plate 27.

At this time, the rotating plate 1 23 is not limited, so that the rotating plate 1 23 drives the screw rod 1 22 to rotate, and the screw rod 1 22 drives the driving ring 20 to move upward. The driving block 21 on the driving ring 20 presses the spiral groove 19, thereby causing the vertical pipe 1 to rotate circumferentially, and the bearing member and the adjusting member rotate with the vertical pipe 1, and the antenna body 6 rotates circumferentially with the vertical pipe 1 The antenna body 6 rotates along with the riser 1 to the direction it needs to face; or the screw 1 22 drives the driving ring 20 to move downward, and the screw 1 22 drives the riser 1 to drive the antenna body 6 to reverse, until the antenna body 6 rotates along with the riser 1 to the direction it needs to face; then, the riser 1 is kept stationary, and the screw 29 is rotated, and the lower end of the screw 29 is pressed against the friction groove 1 28 to limit the rotation of the screw 1 22, so as to avoid the screw 1 22 rotating due to accidental touch, causing the direction of the antenna body to change, so that the riser 1 can be limited, and the direction of the antenna body 6 can be fixed; Subsequently, when the inclination angle of the antenna body 6 needs to be adjusted, the screw rod 3 32 is rotated so that the end of the screw rod 3 32 is no longer pressed against the friction groove 2 31, and the drive rod 26 is no longer limited. The drive rod 26 drives the bevel gear 25 to rotate, and the bevel gear 25 meshes with the bevel gear 1 24, so that the bevel gear 1 24 rotates forward, and the worm 11 rotates forward with the bevel gear 1 24, and the worm 11 meshes with the worm wheel 9, so that the worm wheel 9 rotates clockwise (the clockwise rotation of the worm wheel 9 is Figure 4 ), when the worm wheel 9 rotates clockwise, the worm wheel 9 drives the two gears 10 to rotate clockwise via the rotating rod 8, and the two gears 10 simultaneously mesh with the teeth 7 on the connecting plate 5 on the same side, driving the connecting plate 5 on the same side to rotate clockwise, and the two connecting plates 5 rotate clockwise with the central axis of the rotating shaft 14 as the axis, and the two connecting plates 5 drive the antenna body 6 around the rotating shaft 14 through the U-shaped plate 13 to tilt the upper end to the right until the antenna body 6 is adjusted to the required inclination angle; or the driving rod 26 is rotated in the opposite direction, and the driving rod 26 drives the worm 11 to rotate in the opposite direction, and the worm 11 meshes with the worm wheel 9 to rotate counterclockwise (the counterclockwise rotation of the worm wheel 9 is Figure 4 The two gears 10 rotate counterclockwise with the worm gear 9, and the two gears 10 drive the connecting plate 5 on the same side to rotate counterclockwise, and the antenna body 6 gradually tilts to the left at the upper end around the rotating shaft 14 along with the two connecting plates 5 until the antenna body 6 is adjusted to the required inclination angle; after the inclination angle of the antenna body 6 is adjusted, the screw rod 3 32 is rotated so that the free end of the screw rod 3 32 presses against the friction groove 2 31, and the rotation of the limit driving rod 26 is prevented from being accidentally touched. At this time, the inclination angle of the antenna body 6 is fixed; the present invention does not need to climb up to adjust the inclination angle of the antenna body 6, and the adjustment is convenient; In the present invention, after the inclination angle of the antenna body 6 is adjusted, the teeth 7 on the two connecting plates 5 are engaged and limited by the gears 10 on the same side. Due to the self-locking property of the worm wheel 9 and the worm 11, the worm wheel 9 cannot drive the worm 11 to rotate. When the worm 11 does not rotate, the two connecting plates 5 connected by the U-shaped plate 3 will not rotate under the action of external force (the external force is the force applied to the bearing member by wind and rain, etc.). Therefore, the upper end of the U-shaped plate 3 where the antenna body 6 is located is fixed by the upper ends of the two connecting plates 5, the lower end of the U-shaped plate 3 is fixed by the lower ends of the two connecting plates 5, the middle part of the U-shaped plate 3 is connected to the vertical pipe 1 via the connecting rod 4, and the U-shaped plate 3 is limited and fixed at multiple locations. Therefore, the present invention can improve the installation stability of the antenna body 6.

[0029] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Without violating the spirit of the present invention, that is, within the scope of disclosure, any multiple equivalent or equivalent modifications or replacements of the technical solutions of the invention belong to the protection scope of the present invention.
