The shield machine cutter head is hoisted onto the upper surface of the base by a hoisting device. The transmission structure drives the moving component to move to the upper surface of the shield machine cutter head, and the shield machine cutter head is fixed by the hydraulic component. Among them, there is a transmission structure, one end of the transmission structure is provided with a moving component, and the moving component is internally provided with a hydraulic component for fixing the placed shield machine cutter head. When placing the shield machine cutter head, the transmission structure drives the moving component to move, reserving enough space for placing the shield machine cutter head, facilitating the placement of the shield machine cutter head, and preventing the problem that the shield machine cutter head collides with the hydraulic component and is damaged.

In this case, not only will it consume more working time, but it will also have an adverse impact on aspects such as processing efficiency. Content of the Utility Model
