Setting group number and position are corresponding, and in the present embodiment, limiting slot 92 is provided with 6, and is along the circumferential direction distributed.Transposition plate 21 exists
When circumferencial direction rotation transposition, limited post 91 cooperates with 71 upper limit position groove 92 of upper support frame respectively, realizes that transposition plate 21 limits；It changes
When position disk 21 replaces, due to having spring structure on limited post 91, driving unit driving limited post 91 overcomes the bullet of its own
Power cooperates so that limited post 91 jumps out limiting slot 92 with another limiting slot 92.
The working principle of the invention is: drive shaft 1 being connect with driving unit, driving unit drives drive shaft 1 to first
When direction of rotation rotates, since the first, second single direction rotation part 41,42 can one-directionally rotate along the first direction of rotation, so first,
Second single direction rotation part 41,42 follows drive shaft 1 to drive transposition component 2 is whole to rotate along the first direction of rotation, and then band is moved
Position wheel 22 revolves along the first direction of rotation；Since third single direction rotation part 43 can only be one-directionally rotated along the second direction of rotation, so
When drive shaft 1 rotates along the first direction of rotation, third single direction rotation part 43 is not able to rotate, so driving wheel 3 will not rotate.
Transposition wheel 22 revolution to the aerial position for needing to adjust angle of declination, and to the output wheel of corresponding first output at the position
612 and second driven wheel 611 be meshed and holding position is constant.
When driving unit drives drive shaft 1 to rotate to the second opposite direction of rotation, due to the first, second single direction rotation part
41, it 42 can only one-directionally rotate along the first direction of rotation, so the first, second single direction rotation part 41,42 is not able to rotate at this time, so
Transposition plate 21 will not rotate, i.e., holding position is constant at this time for transposition plate 21；Since third single direction rotation part 43 can be along the second rotation
Turn direction one-directional rotation, so third single direction rotation part 43 rotates, and then band when drive shaft 1 is rotated along the second direction of rotation
Dynamic driving wheel 3 carries out power output；Driving wheel 3 drives the first driven wheel 5 being engaged with to rotate to the first direction of rotation；First
Driven wheel 5 drives the second driven wheel 611 being engaged with to rotate along the second direction of rotation in turn；Second driven wheel 611 rotate into
And drive the rotation along the first direction of rotation of transposition wheel 22 being engaged with；The rotation and then drive of transposition wheel 22 are engaged with defeated
612 rotation of wheel out, the rotation of output wheel 612 drive the output wheel set 622 being engaged with to rotate, so that the angle of declination to antenna carries out
It adjusts.
Disclosed another technical solution: a kind of multifrequency antenna, including (figure is not at least one phase-shifting unit
Show) and above-mentioned antenna drive device, phase-shifting unit is connected with the output wheel 612 of output precision or output wheel set 622, passes through output
The corresponding angle of declination for adjusting phase-shifting unit of the rotation output of wheel 612 or output wheel set 622.
Technology contents and technical characteristic of the invention have revealed that as above, however those skilled in the art still may base
Make various replacements and modification without departing substantially from spirit of that invention, therefore, the scope of the present invention in teachings of the present invention and announcement
It should be not limited to the revealed content of embodiment, and should include various without departing substantially from replacement and modification of the invention, and be this patent Shen
