Accurate placing mechanism for curbs

The invention provides an accurate kerb placing mechanism, and relates to the technical field of kerb laying. The accurate kerb placement mechanism comprises a machine base and a machine frame arranged above the machine base, a driving assembly is installed on the inner wall of the machine frame, a first connecting plate is fixedly connected to the lower surface of the driving assembly, and a fine adjustment assembly is installed in the first connecting plate; the lower surface of the fine adjustment assembly is fixedly connected with a T-shaped installation frame, and clamping assemblies are installed at the two ends of the T-shaped installation frame. By designing a first calibration assembly and a second calibration assembly, when a kerb is clamped by a clamping assembly and faces the direction of a bearing assembly through rotation of a rack, whether rays emitted by a laser pen are located on the center line of a calibration plate in the bearing assembly or not can be judged through data obtained by two i
