The rocker column 26 is slidably connected to the inner wall of the guide sleeve 24, and the outer wall of the rocker column 26 is fixedly installed with a sliding column 28 that is used to slide and fit with the inclined groove 23 and the guide groove 25. The rocker cap 27 is fixedly installed on the top of the rocker column 26. The outer wall of the rocker cap 27 is used to avoid the clearance groove 12. The outer wall of the rocker cap 27 is used to limit the sliding with the side wall of the limiting plate 13. The transmission component 9 is connected to the outer wall of the rotating sleeve 22.

[0057] The protective component 3 includes a housing 31 and a slide 32. The housing 31 is fixedly installed on the upper rear end of the unmanned vehicle. There are four slides 32, which are symmetrically opened on the front and rear side walls of the housing 31.

The inclined groove 23 on the rotating sleeve 22 rotates and drives the sliding column 28 on the rocker arm 26 to slide along the inclined groove 23 and the guide groove 25. The sliding column 28 drives the rocker arm 26 to slide along the inclined groove 23 and the guide groove 25. As the guide sleeve 24 slides upward along its inner wall, the rocker arm column 26 drives the rocker arm cap 27 to move. The rocker arm cap 27 slides along the side wall of the limiting plate 13 until the outer wall of the rocker arm cap 27 disengages from the limiting plate 13. Then, the rack 92 disengages from the gear 91. At this time, the rocker arm cap 27 extends out of the clearance groove 12, and the operator can operate the rocker arm cap 27. The rocker arm cap 27 indirectly drives the upper operating end of the wired rocker arm body 21 to move, thereby realizing reliable wired rocker arm control.

[0060] When in use, this utility model provides sealing protection for the wired rocker body 21 when it is not in use through the housing 31 and the rear cover 11.
