When the first limiting member 206 moves, it drives the first fixing member 204 to move inside the first arc gear rod 203 and squeezes the first spring rod 207. When the first limiting member 206 moves to a position where it is not connected with the laser sensor 209, the laser sensor 209 is connected to the receiver, and the control device is used to power the electric rod 210 to start. , push the first limiting member 206, when the first arc gear rod 203 moves, it engages with the fixed gear 202 to rotate on the surface of the support rod 201, the fixed gear 202 rotates to engage with the second arc gear rod 211 to move, the second arc gear rod 211 drives the second limiting member 214 to move out from the inside of the second fixed sleeve 216 and squeezes the second spring rod 215, when the eyepiece observes the outside of the corner of the eye, press the keypad, the keypad cuts off the power to the electromagnetic block 220 through the control device, and records the rotation path of the eyepiece and the support rod 201, after the recording is completed, twist the rotating ring 218 to reset it;

[0054] The fixed motor 15 is started through the central console, and the fixed motor 15 is reversed. The fixed motor 15 drives the first cone wheel 12, the cone wheel rod 13, the second cone wheel 14 and the rotating screw 10 to reverse, and the moving ring 9 drives the support box 1 to rotate in the opposite direction. When the eyepiece observes the corner of the other eye, the fixed motor 15 is stopped through the central console, and the rotating ring 218 is twisted. The rotating ring 218 drives the friction block to rotate. When the friction block contacts the moved second limiting member 214, friction will be generated, causing the inspector to realize that this is the starting point of the path;

[0055] After the inspection is completed, one of the key plates is pressed down to reset the electric rod 210.

The teeth of the first limiting member 206 and the second limiting member 214 mesh with the fixed gear 202 to rotate.

[0056] The support rod 201 is rotated, and the support rod 201 drives the first gear 5 to rotate. The first gear 5 rotates by meshing the third gear 7 through the second gear 6. The rotation of the third gear 7 can drive the lighting device 8 to rotate, so that the lighting device 8 and the rotating ring 218 rotate synchronously, and their angles are the same;

[0057] By rotating the handle 4, the handle 4 drives the worm 302 to rotate, the worm 302 engages with the worm wheel 303 to rotate, the worm wheel 303 drives the driving gear 305 to rotate through the fixed rod 304, the driving gear 305 engages with the toothed plate 307 through the driven gear 306 to move, the toothed plate 307 drives the moving part 308 to push and pull the support frame 309 to rotate the angle, when the angle sensor 310 fixed on the support frame 309 is subjected to the angle deflection, the angle deflection signal is transmitted to the control device, and the brightness of the light is adjusted by the control device.

[0058] The above electronic devices are all powered by internal batteries (not shown) or external wires (not shown).
