[0028] It also includes an annular lamp holder 16, which is installed at the lower end of the lifting seat 2, and a light sensor 15 is arranged on one side of the inner wall of the main body 1;

[0029] It also includes a fixing block 17 which is welded to the front and rear ends of the lower sides of the main body 1 . The interior of the fixing block 17 is threadedly connected with a second threaded rod 18 , and both ends of the second threaded rod 18 extend to the outside of the fixing block 17 .

[0030] When in use, start the motor 4 to make the first rotating shaft 5 drive the first bevel gear 6 to rotate synchronously, and the second rotating shaft 7 drives the second bevel gear 8 to rotate under the meshing connection between the first bevel gears 6, and the first threaded rod 9 and the moving block 11 rotate synchronously under the meshing connection between the second bevel gears 8. When the moving block 11 rotates, it will be converted into up and down vertical movement under the axial limit of the guide rod 13, thereby driving the lifting seat 2 to make the detection camera 12 rise and fall synchronously, so as to realize the detection camera 12 to adaptively adjust the height of the workpiece.

A first bevel gear 6 is provided at the lower end of the first rotating shaft 5 and one end of the second rotating shaft 7, and the first bevel gears 6 are meshedly connected. The motor 4 provides power for the rotation of the first rotating shaft 5, and the meshing connection between the first bevel gears 6 realizes the synchronous rotation of the first rotating shaft 5 and the second rotating shaft 7;

[0032] See also Figure 2 and Figure 3 , one end of the second rotating shaft 7 and one end of the first threaded rod 9 are both provided with a second bevel gear 8, and the second bevel gears 8 are meshingly connected, and the meshing connection of the second bevel gear 8 can realize the synchronous rotation of the second rotating shaft 7 and the first threaded rod 9;

Due to the meshing connection between the first bevel gears 6, the second shaft 7 will rotate synchronously. The setting of the bearing 10 ensures the stability of the rotation of the second shaft 7. The second shaft 7 will drive the second bevel gear 8 to rotate. Since the second bevel gears 8 are meshingly connected, the first threaded rod 9 will rotate synchronously. The first threaded rod 9 will drive the moving block 11 to rotate synchronously. When the moving block 11 rotates, it will be axially limited by the guide rod 13, so that the rotation of the moving block 11 can be converted into vertical movement up and down. The moving block 11 will drive the lifting seat 2 to adjust the height, thereby driving the detection camera 12 to rise and fall synchronously, realizing the detection camera The camera 12 can adaptively adjust the height of the workpiece, and is practical. When inspecting the workpiece, the light sensor 15 can detect the light intensity and send the detection result to the single-chip microcomputer 14 for processing. The user can set the standard value in advance. When the light is insufficient, the single-chip microcomputer 14 will start the annular lamp holder 16, and the annular lamp holder 16 will emit bright light to illuminate the detection area below, thereby realizing the light adaptation and making the detection more accurate. Before the detection, the user grasps the handle 19 and rotates it. The handle 19 will drive the second threaded rod 18 to rotate, so that the second threaded rod 18 rotates downward, and the second threaded rod 18 will drive the rubber anti-sliding block 20 to move downward synchronously, so that the friction can be increased through the contact between the rubber anti-sliding block 20 and the ground, thereby increasing the stability of the main body 1 during use, and avoiding the movement of the main body 1 affecting the detection effect.
