By designing multiple oblique grooves 82, the oblique block 83 can slide into the oblique grooves 82 at different positions, the oblique block 83 is slidably connected to the slider 13, the outer side of the oblique block 83 is hinged with a hinge rod 84, the outer side of the hinge rod 84 is fixedly connected with a guide block 85, the guide block 85 and the slider 13 can slide relative to each other, the inner sliding sleeve of the guide block 85 is provided with a guide rod 86, the guide rod 86 is fixedly connected to the slider 13, and a first spring 87 is provided on the outer side of the guide rod 86, one end of the first spring 87 is fixedly connected to the slider 13, and the other end of the first spring 87 is fixedly connected to the guide block 85 The fixed connection is achieved by designing the first spring 87 so that the force of the first spring 87 can act on the guide block 85 . The adjustment mechanism 8 is designed to facilitate adjustment of the height of the laser camera 16 .

[0023] like Figures 1 to 3As shown, the connecting mechanism 9 includes a groove 91, and a groove 91 is opened inside the mounting seat 15. A ball 92 is movably sleeved inside the groove 91, and a connecting block 93 is movably sleeved on the outside of the ball 92. A connecting rod 94 is slidably sleeved inside the connecting block 93.

[0024] The specific implementation process of the present invention is as follows: when in use, the prefabricated building component to be inspected is placed on the inspection platform 1, and then the motor 5 is started. The output end of the motor 5 drives the screw 6 to rotate. Through the threaded connection between the screw 6 and the connecting rod 7, the connecting rod 7 makes a threaded movement. The connecting rod 7 can drive the fixed block 11 to move, and then drive the laser camera 16 to move, so that the workpiece can be mobile quality inspected. After the quality inspection, the workpiece size and accuracy can be compared with the BIM model.

[0025] When the operating height of the laser camera 16 needs to be adjusted, the slider 13 is directly pulled in the vertical direction. The slider 13 drives the inclined block 83 to move. The inclined block 83 will slide along the inclined groove 82. The inclined block 83 will be squeezed by the inclined surface of the inclined groove 82. The movement of the inclined block 83 will cause the hinge rod 84 to deflect. The hinge rod 84 will simultaneously drive the guide block 85 to slide along the guide rod 86. The guide block 85 will squeeze the first spring 87, so that the inclined block 83 can be separated from the inclined groove 82. As the slider 13 drives the inclined block 83 to move, the elastic action of the first spring 87 will give the guide block 85 a reverse thrust. Then the inclined block 83 moves horizontally and resets so that the inclined block 83 is inserted into the inclined groove 82 at another position. The inclined block 83 can be plugged into the inclined groove 82 at different positions, which is convenient and flexible to adjust the operating height of the laser camera 16.

[0026] When the laser camera 16 needs to be disassembled, the mounting base 15 is directly rotated, and the groove 91 inside the mounting base 15 will roll relative to the ball 92. The arc surface of the groove 91 will squeeze and push the ball 92 to move, and the ball 92 will drive the connecting block 93 to move. The connecting block 93 will slide along the connecting rod 94 and squeeze the second spring 95. At the same time, the connecting block 93 squeezes the elastic block 96 to separate the ball 92 from the groove 91. When the ball 92 rotates to the upper inner side of the mounting base 15, the mounting base 15 can be separated from the connecting column 14 by moving the mounting base 15 horizontally, which facilitates the removal of the mounting base 15 and the inspection and maintenance of the laser camera 16.
