We are using ultra small stainless steel clamp. We use one to six pieces at an interval of 2 to 300 mm to fix the long work. The fixation force per piece is considerably inferior to the vice, but because it is one touch, even if there are many fixation points, it does not matter. It is quite convenient for repetitive fixation removal of objects whose shape is fixed. Repeat durability is in use for 2 to 30 times / day for more than 2 years. Since the clamp rotating part is still worn out, it is caulked in a timely manner and it is used. We are currently considering fixing the fixing jig by using a jig.
