[0032] The torque loading mechanism 16 includes a pull rod 18, and two detachable first clamping plates 19 are connected to the middle of the pull rod 18. The first clamping plates 19 clamp the corresponding rudder wings 7 in the left and right directions. The first clamping plates 19 located on the inner side are fixed to the pull rod 18, and the ends of the first clamping plates 19 located on the outer side are provided with L-shaped limit cards 20. The first clamping plates 19 are clamped on the same side ends of the inner first clamping plates 19 through the L-shaped limit cards 20, and a positioning groove for positioning and clamping the rudder wings 7 is formed between them. The outer first clamping plates 19 are also provided with L-shaped limit cards 20. A first spring latch 21 with a locking end positioned and passed through the rudder wing through hole 9, the first spring latch 21 includes a mounting groove 22 opened on the inner side of the outer first clamping plate 19, and a pin shaft 23 coaxially arranged with the through hole 9 of the corresponding rudder wing 7 passes through the mounting groove 22, the pin shaft 23 extends outward from the outer first clamping plate 19 and is connected with a nut 24, a spring 25 is arranged between the pin shaft 23 and the bottom of the mounting groove 22, and the spring 25 is used to push the locking end of the pin shaft 23 to lock in the through hole 9 of the corresponding rudder wing 7.

During the downward process of the steering gear outer tube 4, the steel ball 13 is pushed to compress the compression spring 14 inward. When the position of the mounting countersunk hole 8 corresponds to the position of the steel ball 13, the compression spring 14 pushes the steel ball 13 to be locked in the mounting countersunk hole 8, so that the positioning installation of the steering gear outer tube is realized. After that, the butterfly screw 12 is tightened to prevent the steering gear outer tube 4 from accepting up and down displacement.

[0037] When disassembling, the servo outer tube 4 can be taken out by twisting the butterfly screw 12 outwards.

[0038] When the torque loading mechanism 16 is connected, first pull out the pin 23 of the first spring latch servo outer tube 421, clamp the L-shaped limit card 20 of the outer first clamping plate on the same side end of the inner first clamping plate 19, and clamp the rudder wing 7 in between, then release the first spring latch 21 to lock the pin 23 in the through hole 9 corresponding to the rudder wing 7.
