Measurement device for thrust line of rocket launching unmanned aerial vehicle

The invention relates to a measurement device for an unmanned aerial vehicle, in particular to a measurement device for a thrust line of a rocket launching unmanned aerial vehicle. The technical problems are solved that for an existing measurement device for a thrust line of a rocket launching unmanned aerial vehicle, measurement is inconveniently conducted, and the measurement efficiency and precision are low. According to the technical scheme, the measurement device for the thrust line of the rocket launching unmanned aerial vehicle comprises an upper steel wire rope, a thrust bearing connection rod fixedly and axially connected with the upper steel wire rope, a thrust bearing connection sleeve sleeving the exterior of the thrust bearing connection rod, a thrust bearing arranged betweenthe thrust bearing connection rod and the thrust bearing connection sleeve, a lower steel wire rope, a rectangular measurement cylinder sleeving the exterior of the lower steel wire rope, and a measurement ruler for measuring
