At this time, the inclined plate 11 on the opening is aligned with the fixed slot of the slot. By rotating the screw rod 6, the screw rod 6 rotates stably in the opening through the bearing seat 7. The screw rod 6 passes through the screw hole of the sliding block 8, which can make the sliding block 8 move in the adjustment slot. The sliding block 8 can move linearly in the adjustment slot through the guide mechanism. The sliding block 8 drives the inclined block 9 to move. The inclined block 9 contacts the inclined part of the inclined plate 11, and then the inclined plate 11 moves linearly in the opening. The elastic component 10 is squeezed and deformed by the connecting frame, and the inclined plate 11 rests on In the fixed groove, the maintenance plate 3 is firmly fixed in the groove. During use, the external protection mechanism can facilitate the external connection of the pipeline of the hydraulic servo mechanism 4, and can also play a role in sheltering from rain. When regularly inspecting or maintaining the hydraulic servo mechanism 4, the personnel open the side door 5, and then only need to reversely rotate the screw rod 6 to make the sliding block 8 move straightly in the adjustment groove, and the inclined block 9 leaves the inclined plate 11.
