[0028] The elevation parts are used to establish the tooling coordinate system to adjust the relative positions between the positioning structures and the positioning connection structures.

[0029] The utility model is used as an example Figure 3 As shown, to use the device, first remove the old horizontal tail actuator connector from the helicopter's slant beam. Then, position the center and tail reduction platforms at each end of the device onto the corresponding positions on the helicopter's tail structure and use locating pins to position the device on the tail structure. The new horizontal tail actuator connector is positioned using the horizontal tail actuator connector positioning structure in the center of the device. At this point, assemble the new horizontal tail actuator connector to the slant beam according to the assembly process requirements. After completing the relevant assembly operations, remove the device to complete the replacement of the horizontal tail actuator connector.
