Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] The specific settings and functions of this embodiment are described in detail below. The first supporting plate 51 and the second supporting plate 52 are both used to lift the workpiece. When in use, the workpiece can be placed on the first supporting plate 51 or the second supporting plate 52, and then the laser scanner body 3 scans the workpiece from above, and the laser scanning panels 4 on both sides scan the side of the workpiece. The scanning structure is transmitted to the laser scanner body 3 in real time, thereby completing the 3D scanning of the workpiece. The bottom of the first supporting plate 51 and the second supporting plate 52 are both provided with reinforcement rods 514 to improve their own structural strength;

[0026] During the scanning process, the height and horizontal position of the second supporting plate 52 can be adjusted. When the position of the workpiece needs to be adjusted, the workpiece is placed on the second supporting plate 52, and then the reduction motor 54 is used to drive the first supporting plate 51 to rotate. The second supporting plate 52 is directly pulled by the connecting plate 510 at the end of the first supporting plate 51. The connecting plate 510 is installed on the protective plate 56, and the whole is a bent structure to ensure that the second supporting plate 52 can rotate normally.

[0027] The reduction motor 54 is installed on the side of the positioning block 57, and the positioning block 57 determines the rotation center of the first support plate 51 to ensure that there will be no problems of misalignment and wrong direction. A sub-plate 55 is set on the top of the second support plate 52. The sub-plate 55 is used to protect the second support plate 52 and limit the side of the first support plate 51. The sub-plate 55 is inserted into the second support plate 52 through a limiting rod 515.

[0028] Embodiment 2: Figure 1 and Figure 2 As shown, two tilting rods 58 in opposite directions are fixedly installed on the top of the two positioning blocks 57, one side of one tilting rod 58 is rotatably connected to the first support rod 59, and one side of the other tilting rod 58 is rotatably connected to the second support rod 512, a first connecting rod 511 is fixedly installed on the connecting plate 510 on one side of the second supporting plate 52, and the first connecting rod 511 remains parallel to the tilting rod 58 on the positioning block 57 on the same side, a second connecting rod 513 is fixedly installed on the connecting plate 510 on the other side of the second supporting plate 52, and the second connecting rod 513 remains parallel to the tilting rod 58 on the positioning block 57 on the same side, one end of the first support rod 59 is rotatably connected to one end of the first connecting rod 511, and one end of the second support rod 512 is rotatably connected to one end of the second connecting rod 513.

[0029] The effect achieved by the entire embodiment is that the first support rod 59 is connected to the first connecting rod 511, and the second support rod 512 is connected to the second connecting rod 513. Since the first connecting rod 511 and the second connecting rod 513 are both fixedly mounted on the side of the connecting plate 510, the angle between them and the connecting plate 510 is fixed. As long as the first connecting rod 511 and the second connecting rod 513 are fixed, the angle of the connecting plate 510 can be determined. The lengths of the first support rod 59 and the second support rod 512 are both fixed. Therefore, during the rotation of the first supporting plate 51, the first support rod 59 and the second support rod 512 can drive the second supporting plate 52 through the first connecting rod 511 and the second connecting rod 513, and keep the second supporting plate 52 at a horizontal angle at all times to avoid affecting the stability of the workpiece. In addition, the structure in which the tilting rod 58 is in opposite directions can not only make a certain angle between the first connecting rod 511 and the second connecting rod 513, but also ensure that the lengths of the first support rod 59 and the second support rod 512 are equal.

[0030] The use method and working principle of the device: When in use, the workpiece can be placed on the first supporting plate 51 or the second supporting plate 52, and the auxiliary plate 55 can limit the side of the first supporting plate 51. Then the laser scanner body 3 scans the workpiece from above, and the laser scanning panels 4 on both sides scan the side of the workpiece. The scanning results will be transmitted to the laser scanner body 3 in real time, thereby completing the 3D scanning of the workpiece;

[0031] During the scanning process, if the position of the workpiece needs to be adjusted, the workpiece is placed on the second supporting plate 52, and the reduction motor 54 drives the first supporting plate 51 to rotate. The second supporting plate 52 is directly pulled through the connecting plate 510 at the end of the first supporting plate 51. The positioning block 57 will determine the rotation center of the first supporting plate 51. The connecting plate 510 is a bent structure to ensure that the second supporting plate 52 can rotate normally. In this process, the first support rod 59 and the second support rod 512 will also drive the second supporting plate 52 through the first connecting rod 511 and the second connecting rod 513 to ensure that the second supporting plate 52 always remains at a horizontal angle to avoid affecting the stability of the workpiece.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
