[0075] like Figure 15 and Figure 16 As shown, the outer cylinder 2 is fixedly installed inside the support device 6 via a fixed shaft 23. The mounting rod 1 passes through the outer cylinder 2 and is connected to the first electro-hydraulic rod 41. The external thread 12 on the mounting rod 1 is screwed into the internal thread 22 on the outer cylinder 2. The first electro-hydraulic rod 41 drives the mounting rod 1 to move along the thread.

[0076] In addition, the angle monitoring chip is installed on the observation instrument mounting platform 13.
