The invention relates to the technical field of model test in ship and ocean engineering, in particular to a sensor combining push-pull force of a propeller model and interference-free torque measurement. The sensor comprises a sensor body. A propeller fixing region, a pull-push force test region, a torque test region and a power transmission connection region are arranged on the sensor body. A propeller is fixedly installed in the propeller fixing region. The power transmission connection region is fixedly installed on a driving host. The sensor body is capable of measuring push-pull force and torque of the propeller in a working state through the pull-push force test region and the torque test region. According to the invention, push-pull force and torque generated by the propeller are measured from the root of the propeller, so it is ensured that the measurement of the push-pull force and the torque of the propeller is free from effects of frictional force and frictional torque between a shaft and a shaft
