Claims

[Claims for Utility Model Registration] (1) The extension spring part 2 of the fine movement handle device 1 with a spring extension part, which is used in the mount of a telescope, etc., is attached around the rotation shaft bearing part 3 which is the base thereof. A fine movement handle device characterized in that it is rotatably passed through a fixed bendable tube 4. (2) Claims for registration of a utility model characterized in that a sliding ring 5 is fixed to the outside of the extension spring portion 2, and a sliding ring 6 is also fixed to the inside of the bendable tube 4 corresponding thereto. The fine movement handle device according to item 1. (3) A utility model registration claim characterized in that a sliding ring 7 is rotatably fixed to the outside of the extension spring portion 2, and this sliding ring 7 is also rotatable within the bendable tube 4. 1st
Fine movement handle device as described in section. (4) Near the end of the bendable tube 4,
The corresponding extension spring 2 or the straight rod portion 12 extending from the end of the extension spring 2,
The fine-movement handle device according to claim 1, characterized in that a convex portion and a concave portion are provided that engage with each other.
