[0006] The top of the support seat is provided with a calibration device for driving the working plate to move, which includes a groove, the groove is opened at the top of the support seat, and a positioning block is fixedly connected to the inner center of the groove, a hinge one and a hinge two are provided between the surface of the positioning block and the inner wall of the groove, an electric telescopic rod one is provided between the opposite surfaces of the hinge one and the hinge two, one end of the hinge one is hinged on the surface of the positioning block, and the other end is provided at the bottom of the electric telescopic rod one, one end of the hinge two is hinged at the output end of the electric telescopic rod one, and the other end is provided with the electric telescopic rod two, the bottom of the electric telescopic rod two is fixedly connected with a hinge three, and the output end is hinged with a hinge four, the hinge four is hinged to the bottom of the working plate, a positioning assembly is provided on the top of the positioning block, and includes a support column and a protective box, the inner wall of the protective box is fixedly connected with a limited block, the interior of the protective box is slidably connected with a positioning plate, and the surrounding sides of the positioning plate are slidably connected to the interior of the protective box and the surface of the limit block.

[0007] Furthermore, an infrared adapter is provided at the top center of the working board and cooperates with the video crosshair display. Specific infrared signals may be emitted through the infrared adapter and captured by the receiver on the video crosshair display. The receiver converts the received signals into video signals or digital signals, thereby providing effective support for calibration.

[0008] Furthermore, an accordion protective cloth is arranged between the working plate and the groove to form a protection between the support seats. The protection is to prevent dust, debris, liquid or other contaminants from entering the mechanical parts or moving parts in the area below and causing interference or damage thereto. There is a certain gap between the groove and the working plate, and this gap needs to be closed by the accordion protective cloth.

[0009] Furthermore, the electric telescopic rod 1 and the electric telescopic rod 2 are respectively provided with four groups, and are respectively arranged at four positions of the groove.

[0011] Furthermore, the bottom of the support column is fixedly connected to the top of the positioning block, and the top is fixedly connected with a nut 1, and the internal thread of the nut 1 is connected with a threaded rod 1. Through the rigid connection between the positioning block, the support column and the nut 1, the entire mechanism obtains good stability in the vertical direction.

[0013] Furthermore, both ends of the threaded rod 2 are rotatably connected with clamping columns, and the clamping columns are provided with four groups, and are respectively fixedly connected to the top surface of the clamping columns. The clamping columns are distributed on the positioning plate through the four groups, so that the force exerted on the positioning plate is evenly distributed.
