[0037] Furthermore, a spline groove 51 is provided at one end of the barrel shaft 5 passing through the actuator fixture 4, and this spline groove 51 is used to install the spline shaft at the bottom of the actuator to be measured.

[0038] In order to prevent the torque sensor 2 from shaking during the working process of the running-in tooling, a support 8 is provided between the torque sensor 2 and the base 1. The support 8 is provided with a U-shaped groove, and the torque sensor 2 is placed in the U-shaped groove.

[0039] Furthermore, mounting holes 11 are respectively provided on the base 1 corresponding to the bracket 3 and the support 8, and the bracket 3 and the support 8 are mounted on the base 1 through the mounting holes 11.
