摘要： A transmission switching device, comprising a linear transmission member (1), a transmission shaft (2), a transmission assembly (3), and a switching output assembly (4). The transmission assembly comprises a support (31) and a driving gear (32), the driving gear and the transmission shaft being both rotatably mounted on the support. The transmission shaft is coaxially connected to the driving gear and is used for driving the driving gear to rotate. The linear transmission member is connected to the support and is used for driving the support to reciprocate. The switching output assembly comprises a plurality of switching output shafts (41), each switching output shaft being provided with a switching output gear (42). The driving gear can be in driving connection with the plurality of switching output gears. The transmission switching device may switch and output to different phase shifters power input into the transmission assembly, so that the phase shifters are driven by fewer driving members, and thus the number of the driving members is reduced. Further provided are a driving device comprising said transmission switching device, and a base station antenna.
