To be more specific, a bidirectional screw rod 7 is arranged between the two support plates 4, driving the motor 8 fixedly installed on one side of the support plates 4, so that the bidirectional screw rod 7 rotates and drives the two movable seats 9 to move toward each other, the connecting blocks arranged on the tops of the two movable seats 9 drive one end of the movable rod 10 to lift up, and the other end of the movable rod 10 drives the workbench 3 to move up and down to adjust the height, and the telescopic rod 2 between the bottom of the workbench 3 and the top of the base 1 moves synchronously, thereby ensuring the stability of the workbench 3 and improving the accuracy of detection.

[0024] refer to Figure 1 and Figure 3The detection structure 6 includes two symmetrical fixed blocks 11, and the side walls at both ends of the two fixed blocks 11 are provided with sliding grooves, and a protective cover 12 is slidably installed inside the sliding groove. A cylinder 13 is also fixedly installed on one side of the fixed block 11. The output end of the cylinder 13 passes through the through hole opened in the side wall of the fixed block 11 and is connected to one side of the mounting seat 14. A T-shaped slot 15 is opened inside the mounting seat 14, and a latch 16 is arranged in the through hole opened at the top of the mounting seat 14. A detection pressure block 17 is also arranged on one side of the mounting seat 14, and a T-shaped block is arranged at one end of the detection pressure block 17.
