In order to simplify the structure and reduce the manufacturing cost, the fixture only slides back and forth in the range of the straight line section of the cutter head ruler main body. In use, as the cutter head of the shield machine generally has a small number of side hobs, when the distance of the side hobs needs to be measured, the distance can be visually observed through the scribed line marks on the arc module. When the diameter of the cutter head changes, the use requirements of different cutter head diameters can be met by increasing and decreasing the splicing number of the linear modules. When the edge shape of the cutter head changes, the requirements of different edge shapes of the cutter head are met by replacing the arc module.

As the utility model discloses a further improvement, foretell locking mechanical system is the hand wheel structure, and the hand wheel structure is provided with the height adjustment structure to install on fixture through the height adjustment structure, the during operation, through the relative height of adjustment hand wheel mechanism with fixture, change fixture and blade disc chi main part sliding gap, thereby realize fixture slip or lock state around on blade disc chi main part.

As the utility model discloses a further improvement, foretell hand wheel structure is when locking fixture in blade disc chi main part, for preventing that hand wheel structure or fixture from causing the abrasion damage to blade disc chi main part, foretell hand wheel structure is provided with the gasket, and this gasket is located hand wheel structure and blade disc chi main part contact department, and gasket hardness slightly is less than blade disc chi main part hardness.

As the utility model discloses a further improvement, foretell height adjustment structure is helicitic texture, and the structural bolt pole that has the external screw thread that sets up of hand wheel, and be provided with on the fixture can with the bolt pole matched with screw hole of hand wheel structure.
