摘要： A multiband antenna transmission, including: a driving gear, a shifter, and a plurality of screw assemblies. The position and the driving gear are coaxially and rotatably arranged, and the shifter comprises a plate and a boss protruding from a side of the plate. The plurality of screw assemblies are arranged in a circumferential direction of the driving gear. Each of the plurality of screw assemblies includes: a lead screw, a driven gear selectively connected with or separated from the lead screw, and a first elastic member arranged between the lead screw and the driven gear. The boss is configured to sequentially push the driven gear of the respective screw assembly during rotation of the shifter, such that the driven gear is connected with the corresponding lead screw and whereby the driven gear is in mesh with the driving gear for transmission.

摘要： The multi-frequency antenna transmission, including a drive gear, a gear train with parallel gear shafts, screw assemblies and a shifter. The transmission gears are connected to the stoppers of the screw assemblies one by one, the drive gear drives the various transmission gears to rotate, and all the stoppers rotate. The shifter pushes the stopper of one of the screw assemblies, such that the first elastic member disposed between the connection member and the stopper is compressed, and the connection member is connected to corresponding lead screw, thus the power of the stopper is transmitted to corresponding lead screw through the compressed first elastic member and the connection member, and drives the lead screw to rotate.
