The main function of the wire rope thimble is to adjust the clamping force, ensuring that the clamp can firmly clamp the file without damaging it. The wire clamp usually consists of two curved wire clamp arms, which are connected by a thimble. The number and position of the thimbles can adjust the width of the clamp and the clamping force. The more thimbles there are, the greater the clamping force of the clamp, but too many thimbles may cause damage to the clamp. When using it, you need to adjust the size of the clamp according to the thickness of the file to ensure that the file is firmly clamped without damaging it.
