Move position wheel 22 to revolve round the sun along the first direction of rotation；Due to the 3rd single direction rotation part 43 can only along the second direction of rotation one-directional rotation,
So when drive shaft 1 rotates along the first direction of rotation, the 3rd single direction rotation part 43 can not rotate, so driving wheel 3 also will not
Rotate.The revolution of transposition wheel 22 is to the aerial position for needing regulation angle of declination, and the first output corresponding to the opening position is defeated
Go out the driven pulley 611 of wheel 612 and second to be meshed and holding position is constant.
Driver element drive drive shaft 1 to opposite the second direction of rotation rotate when, due to first, second single direction rotation part
41st, 42 can only along the first direction of rotation one-directional rotation, so now first, second single direction rotation part 41,42 can not rotate, so
Transposition plate 21 will not also rotate, i.e., now holding position is constant for transposition plate 21；Because the 3rd single direction rotation part 43 can be along the second rotation
Turn direction one-directional rotation, so when drive shaft 1 rotates along the second direction of rotation, the 3rd single direction rotation part 43 rotates, and then band
Dynamic driving wheel 3 carries out power output；Driving wheel 3 drives the first driven pulley 5 being engaged with to be rotated to the first direction of rotation；First
The second driven pulley 611 that driven pulley 5 and then drive are engaged with rotates along the second direction of rotation；Second driven pulley 611 rotate into
And the transposition wheel 22 that is engaged with is driven along the first direction of rotation rotation；The rotation and then drive of transposition wheel 22 are engaged with defeated
Go out wheel 612 to rotate, output wheel 612, which rotates, drives the output wheel set 622 being engaged with to rotate, so as to carry out the angle of declination of antenna
Regulation.
Another technical solution disclosed in the utility model：A kind of multifrequency antenna, including at least one phase-shifting unit (figure
Do not show) and above-mentioned antenna drive device, phase-shifting unit is connected with the output wheel 612 or output wheel set 622 of output precision, by defeated
Go out the angle of declination of the corresponding regulation phase-shifting unit of rotation output of wheel 612 or output wheel set 622.
Technology contents and technical characteristic of the present utility model are had revealed that as above, but those skilled in the art still may be used
A variety of replacements and modification without departing substantially from the utility model spirit can be made based on teaching of the present utility model and announcement, therefore, this
