The rigid plate body design can avoid force transmission deviation caused by loose connection and ensure the consistency of system operation.

[0043] In combination with the accompanying drawings Figures 1 to 7 The working principle of the above embodiment is as follows: First, the automatic conveying equipment conveys the environment-friendly meal box, after conveying to the detection position, the telescopic cylinder 5 receives the control signal to start working, the push rod of the telescopic cylinder 5 extends, drives the connecting table 611 connected therewith to move up and down, and the connecting table 611 is fixedly connected with the lifting sleeve 61, so that the lifting sleeve 61 moves up and down accordingly; The lifting sleeve 61 is internally provided with a sliding piece 610, and the roller 6102 thereon is embedded in the driving sliding groove 621 on the outer surface of the driving shaft 62. The driving sliding groove 621 is a slanted groove arranged around the outer surface of the driving shaft 62. When the lifting sleeve 61 moves up and down, the roller 6102 is limited to move in the driving sliding groove 621. Since the sliding groove is slanted, the up and down movement of the roller 6102 forces the driving shaft 62 to rotate around its axis. The bottom end of the driving shaft 62 is connected to the rotating table 65 through the connecting shaft 66 and the universal ball joint 67. The rotating table 65 can be inclined at a certain angle relative to the connecting shaft 66 through the universal ball joint 67. When rotating, the rotating table 65 is provided with a guide column 68 at the edge of the upper surface thereof, and the ball 69 at the top end of the guide column 68 always abuts against the bottom surface of the special-shaped table 64. Since the special-shaped table 64 has different heights on the left and right sides, when the rotating table 65 rotates with the driving shaft 62, the height of the contact point of the ball 69 will periodically change. This height change is transmitted through the guide column 68 to push the rotating table 65 to tilt around the universal ball joint 67, and then the two detection probes 2 installed on the bottom side of the rotating table 65 tilt accordingly, so as to change the detection angle or focal point, realize multi-dimensional detection, and adapt to the detection requirements of meal boxes with different shapes. At the same time, when the telescopic cylinder 5 telescopes to drive the lifting sleeve 61 to move, the connecting assembly 9 drives the first plug rod 73 to compress the first piston block 72. The gas enters the gas hole 14 of the rack 11 through the gas pipe 74 and the suction nozzle 76, so as to fix the position of the meal box and prevent the meal box from deviating due to external force during detection, so as to avoid the detection probe 2 from being inaccurate.

[0044] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
