[0002] A shield machine is a tunnel boring machine that uses the shield method. The basic working principle of a shield machine is that a cylindrical steel component moves forward along the axis of the tunnel while excavating the soil. The shell of the cylindrical component is the shield, which plays a temporary support role for the excavated tunnel section that has not yet been lined, bearing the pressure of the surrounding soil layer, and sometimes also bearing the groundwater pressure and keeping the groundwater out. Excavation, soil discharge, lining and other operations are carried out under the cover of the shield.

[0003] The application number is CN202221293421.4, which discloses a shield machine, including a shield machine body and a shield machine cutter head arranged on the thrust side of the shield machine body, wherein the shield machine cutter head includes a fixed cutter head and a movable cutter head, the fixed cutter head is provided with a roller cutter and a slot hole for the movable cutter head and the crushed soil to pass through, the back of the fixed cutter head is connected to the fixed cutter head mounting frame, the other end of the fixed cutter head mounting frame is provided with a driving shaft, the other end of the driving shaft is connected to the shield machine body by transmission, the movable cutter head includes a movable cutter head and a cutter arranged on the front of the movable cutter head, the back of the movable cutter head is connected to the support rod, the support rod is connected to the shaft sleeve, the shaft sleeve is connected to the driving shaft key, and a movable cutter head drive assembly is also provided in the shield machine body, and the movable cutter head drive assembly is used to realize the extension and retraction of the movable cutter head along the slot hole. When the shield machine of the present application is excavating a tunnel, it can switch the cutter on the cutter head according to the different soil layer structures, so as to adapt to the excavation of soil layers with different hardness and softness.

[0004] A shield machine disclosed in the above document has the following defects: when the cutter assembly of the shield machine cuts the soil block, the impact force drives the cutter to push the soil block forward. When the cutter blade contacts the soil block, due to the hard soil block, a fixing structure needs to be set for the blade. The mechanism only has one cutter disc, which cannot more effectively fix the two sides of the blade, making the cutter assembly not very stable.

[0005] It can be seen that the existing shield machine does not have the function of effectively fixing the left and right sides of the cutter assembly. It is necessary to improve the existing deficiencies and provide a function that can effectively fix the left and right sides of the cutter assembly. Utility Model Content
