[0002] A laser calibration device is a device used to accurately measure, calibrate, and determine the position, size, or other physical quantities of an object. It mainly utilizes the high directionality, high brightness, and good coherence of lasers. The laser beam can propagate in a straight line in space, and its spot size, position, and energy distribution are relatively stable.

[0003] A search revealed Chinese Patent Publication No. CN205537526U, which discloses a portable laser displacement sensor calibration device. This device mainly includes a base, a micrometer, a laser displacement sensor, and a controller. Both the laser displacement sensor and the micrometer are mounted on the base. The laser displacement sensor is positioned so that the light spot accurately illuminates the tip of the micrometer. The sensor is connected to the controller. This device simplifies the calibration steps of the laser displacement sensor, optimizes the calibration method, and improves the efficiency and accuracy of high-precision laser detection. The device provided by this invention is compact and facilitates calibration experiments under different experimental conditions. In contrast, existing portable laser calibration devices are directly welded to the excavator's boom.

[0020] The top of the fixed plate has multiple fixing holes at equal intervals, and a fixing buckle is slidably connected to the inner side of the fixing hole on the front side.

[0021] The above technical solution uses a fixing buckle and a fixing hole to restrict the rotation of the fixing plate.

[0046] When using the portable laser calibration device, if the calibration angle needs to be adjusted, the fixed plate 201 connected by screw 2 9 under the base plate 7 can be rotated. When the fixed plate 201 starts to rotate, the rotating rod 202 fixed under it will also rotate.
