I have an old one with a similar stand. I shimmed the clamp with a thin 1/8 in piece of foam, cardboard would work, where the clamp attaches to the scope body to make that contact tight and lightly sanded the balls on the swivel to get a better grip.

Once you set it to the desired angle you will not need to move it much.

I also made a mat with black ¼ in black craft foam, 2 bucks at Wally mart and glued a strip on one edge to make a raised ledge to rest the razor on so the bevel is parallel to the lens. I lay the razor with the handle open, so the scales are 90 degrees to the spine and hanging off the edge of the pad to hold the razor in place. This puts the razor in the right angle for my set up.

Move the camera, not the razor, I have seen where guys have glued magnetic sheet to the pad, so it does not move. I weigh the scope base down with my keyboard.

I was going to make a larger base from MDF for the weight, but have used the keyboard for years now…

Mine looks identical to yours, if so there are 2 magnifications, low and high power. If you run the focus knob all the way in the opposite direction you will switch to high magnification, mine is supposed to be 60X and 400X once you switch to high you have to sneak up on focus.

Been wanting to buy a new scope, I have dropped mine several times and alignment is a bit wonky and photo are not as clear as newer ones.
