The rotatable mounting seat comprises a base, a connecting plate, a locking/unlocking mechanism, a slewing bearing and a top plate, the connecting plate is fixedly connected to the top of the base, and the locking/unlocking mechanism is mounted on the connecting plate and comprises a guide cylinder, a spring, a positioning pin, a connecting rod, a bent pull rod and a wrench. The bottom of the top plate is fixedly provided with a limiting blocking piece corresponding to the guide cylinder, the top plate is further provided with a positioning hole matched with the positioning pin, and when the guide cylinder abuts against the limiting blocking piece, the top of the positioning pin can stretch into the positioning hole under the action of restoring force of the spring. The bending pull rod and the connecting rod can be sequentially driven by pulling the wrench, and then the positioning pin is driven to overcome the elastic force of the spring to be separated from the positioning hole of the top plate. The rotatable mounting seat and the seat are simple in structure, convenient to adjust, low in failure rate and high in bearing capacity.
