The protection mechanism 2 comprises a connecting plate 201, the protection mechanism 2 is of a rectangular shell structure with a notch formed in the bottom, the connecting plate 201 is arranged on the rear end face of the protection mechanism 2, and ten T-shaped sliding grooves are formed in the left side face, the right side face and the top end face of the interior of the protection mechanism 2; connecting plate 201 is Contraband font structure, and the inside left and right sides face of connecting plate 201 all is equipped with four bar sliders, and both ends face middle part all is equipped with a latch mechanism 4 about connecting plate 201, and the distance equals between the both ends face about the inside left and right sides face of connecting plate 201 and the installation plate 1 outside, and when protection mechanism 2 was in the mounted state with installation plate 1, four bar sliders were connected with four bar spouts slip respectively to it is more firm when installing to installation plate 1 to make protection mechanism 2.

The angle adjusting part 8 comprises a first connecting frame 801, a second connecting frame 802, a locking bolt 803 and a limiting flower gear 804, the first connecting frame 801 is rotatably connected to the rear side of one upper connecting plate part 102 through a rotating shaft, the lower end of the first connecting frame 801 is rotatably connected with the second connecting frame 802 through the rotating shaft, the other end of the second connecting frame 802 is rotatably connected with the upper part of the front side of the supporting plate part 3 through the rotating shaft, and the front end face and the rear end face of the second connecting frame 802 are respectively provided with an anti-loosening assembly 9; a thread through hole is formed in each of the front end face and the rear end face of the second connecting frame 802, a locking bolt 803 is connected in each thread through hole, a limit flower gear 804 is arranged at each of the back ends of the two locking bolts 803, the opposite ends of the two locking bolts 803 penetrate through the arc-shaped through holes in the front side face and the rear side face of the first connecting frame 801 respectively, and the locking bolts 803 are screwed down to turn clockwise.

In another embodiment, strip-shaped sliding grooves are formed in the upper side surface and the lower side surface of the rectangular sliding shell 901, and the upper end surface and the lower end surface of the rectangular sliding block 902 located in the rectangular sliding shell 901 are respectively provided with a roller which is in rolling connection with the strip-shaped sliding grooves of the rectangular sliding shell 901, so that the rectangular sliding block 902 is more labor-saving in pulling operation and has smaller friction loss.

When in use: the arrangement of the protection mechanism 2 can ensure that the outside of the antenna main body 10 can be effectively protected, when the outer wall of the protection mechanism 2 is damaged by exposure to sunlight and rain, the two elastic buckles 403 are manually pinched in opposite directions to ensure that the elastic buckles 403 and the strip-shaped bayonets on the clamping plate 101 lose the clamping relationship, so that the protection mechanism 2 loses the limiting function on the front side of the installation plate 1, then, the protection mechanism 2 is slid forward and removed, and then the antenna main body 10 is taken out from the inside of the protection mechanism 2, then, the antenna main body 10 is installed inside the replaced protection mechanism 2, and then the replaced protection mechanism 2 is clamped to the front side of the installation plate 1 through the clamping mechanism 4, so that the protection mechanism 2 can be easily detached in the whole detaching process without detaching a large number of bolts, and the assembling and disassembling efficiency of the protection mechanism 2 on the antenna device is greatly improved;

when the angle of the antenna device is adjusted, the locking bolt 803 is loosened, then the first connecting frame 801 and the second connecting frame 802 are rotated and adjusted, and the locking bolt 803 is fastened after the angle is adjusted, through the arrangement of the anti-loosening assembly 9, the locking bolt 803 is screwed and turned clockwise, the locking bolt 803 needs to be rotated anticlockwise when the locking bolt is loosened, and the triangular limiting block at the head end of the rectangular sliding block 902 is always in close contact with the outer peripheral surface of the limiting spline gear 804 under the action of the external spring of the pull rod 903, so that the limiting spline gear 804 cannot be rotated anticlockwise at the moment, the locking bolt 803 cannot be loosened, and the stability of the antenna device after the angle is adjusted is improved;

when installing this antenna device to outside branch, at first unscrew fastening nut 702 and take off, then rotate movable splint 502 and open, then overlap solid fixed splint 501 and movable splint 502 outside the branch, then close movable splint 502, make fastener 7 pass bar opening 503, then tighten fastening nut 702 to fastener 7 on, through screwing up fastening nut 702, make movable splint 502 to gu fixed splint 501 department press from both sides tight operation, thereby make this antenna device can install to outside branch fast, and then improved the installation effectiveness when this antenna device is installed greatly.
