Since the first and second compass feet 40, 60 rotate relative to each other, which causes the first and second compass feet 40, 60 to rotate relative to each other, the first and second housings 30, 50 also need to move accordingly.
In order to satisfy the above requirements, in the present embodiment, the main body 10 is provided with a slide rail 101, and the slide rail 101 is arc-shaped or circular.
