The limiting slide groove 18 is opened on the inner side of the shell 1.
[0021] The concave plate 3 is in the shape of a Chinese character "concave", and the outer side of the concave plate 3 is movable inside the shell 1. There are a number of slope blocks 6 fixedly connected to the inner side of the concave plate 3, which facilitates the movement of the concave plate 3 to drive the slope block 6 to move, thereby moving the guide rod 14. The shape of the support shell 10 is in the shape of an inverted "concave", and a groove is provided on the inner side of the support shell 10. The rotating block 12 slides inside the groove inside the support shell 10 through the slider 11. The number of the rotating blocks 12 is the same as the slope block 6, which plays the effect of limiting the position of the rotating block 12 through the slider 11 when the rotating block 12 moves. The rotating blocks 12 are not on the same horizontal line, and the number of the second gears 8 is the same as that of the rotating blocks 12. The first gear 5 and the second gear 8 are not on the same horizontal line, the rotating block 12 and the second gear 8 are on the same horizontal line in a one-to-one correspondence, which facilitates the meshing effect between the first gear 5, the third gear 15 and the second gear 8.

[0022] Working process: when the device is in use, the external power supply is energized. When the downward tilt angle of the phase shifter needs to be adjusted, the electric telescopic rod 2 fixedly connected to the inner side of the lower end of the shell 1 is started, and one end of the electric telescopic rod 2 moves upward. The movement of the electric telescopic rod 2 drives the motor 4 fixedly connected to the upper end to move. The movement of the motor 4 drives the first gear 5 fixedly connected to the end of the main shaft to move. The concave plate 3 moves and drives the slope block 6 fixedly connected inside to move. When one end of the slope block 6 collides with the guide rod 14, according to the shape of the sliding hole 16, the sliding hole 16 gradually moves and drives the guide rod 14 to gradually interact with the inner side of the sliding hole 16 opened on the inner side of the support shell 10. The guide rod 14 moves and drives the rotating block 12 fixedly connected on one side to move. The movement of the rotating block 12 drives the third gear 15 rotatably connected inside to move. The rotating block 12 is slidably connected to the inner side of the support shell 10 through the slider 11 fixedly connected on the outside, which has the effect of limiting the movement of the rotating block 12. When the rotating block 12 moves, one side of the rotating block 12 is fixedly connected The spring 13 is stretched, and the spring 13 has the effect of resetting the rotating block 12. The supporting shell 10 is fixedly connected to one side of the lower end of the shell 1 through the fixing plate 9. When the middle end of the slope block 6 and the middle end of the guide rod 14 are at the same horizontal line, the outer side of the first gear 5 is meshed with the outer side of the third gear 15, and the outer side of the third gear 15 is meshed with the outer side of the second gear 8. The motor 4 fixedly connected to one side of the concave plate 3 is started, and the main shaft of the motor 4 rotates to drive the first gear 5 fixedly connected to the end of the main shaft to rotate. The first gear 5 rotates to drive the third gear 15 meshing on the outside to rotate. The third gear 15 rotates to drive the second gear 8 meshing on the outside to rotate. The second gear 8 rotates to drive the transmission screw 7 fixedly connected on the inside to rotate on the inside of the shell 1. The transmission screw 7 rotates to drive the transmission spiral 17 spirally connected on the outside to slide on the inside of the limiting slide groove 18, which has the effect of limiting the transmission spiral 17. At this time, the adjustment can be completed. When it is necessary to adjust the downward inclination angle of other phase shifters, the same principle can be used.
