The working principle of the technical scheme is as follows: when adopting laser detection driver's expired air's alcohol content, for accurate monitoring, need carry out a lot of to its alcohol content and measure, and in the vehicle driving process from far to near, the incident position of laser is different, and in order to make the incident position of laser tend to unanimity, monitoring devices need rotate certain angle on road test rod 10. The monitoring device is thus fixed to the road measuring pole 10 by means of the rotatable monitoring fixture 20. The monitoring of the rotation of the fixture 20 is as follows: when the vehicle approaches, the microprocessor controls the motor 25 to rotate, the pull belt 24 is wound on the output shaft of the motor 25, and the pull belt 24 is wound on the rotating shaft 23 and rotates along with the rotating shaft, so that the monitoring device is driven to rotate. When the rotating shaft 23 rotates, the spiral spring 272 inside the rotating member 27 on the right side contracts and stores energy, when the monitoring device stops rotating to a preset angle, the spiral spring 272 releases the stored energy to drive the rotating shaft 23 to rotate reversely, and the energy stored by the contraction of the spiral spring 272 is the energy generated when the rotating shaft 23 rotates to a specified angle, so when the energy is released, the reverse rotation angle and the forward rotation angle of the rotating shaft 23 are kept consistent, and the monitoring device can rotate to the original position under the driving of the rotating shaft 23 to monitor the next automobile. The locking wheel 273 serves to prevent the rotation angle of the rotating shaft 23 from exceeding a preset angle, when the motor 25 drives the rotating shaft 23 to rotate, the locking wheel 273 gradually approaches the right side of the rotating housing 271 and finally contacts the rotating housing 271, and when the locking wheel 273 is in hard contact with the rotating housing 271, the rotating shaft 23 cannot continue to rotate, thereby achieving a locking effect.

the locking sleeve body 33 is of a cylindrical ring sleeve structure and is provided with a through hole 34, the through hole 34 is formed in the locking sleeve body 33, mounting sockets 35 are symmetrically formed in the side walls of the two sides of the through hole 34, a micro motor 36 is arranged inside the mounting sockets 35, the output shaft of the micro motor 36 is arranged oppositely, the output shaft is fixedly connected with a semi-arc-shaped clamping plate 38 through a sleeve 37, a buffer pad 39 is further bonded on the inner wall of the semi-arc-shaped clamping plate 38, and the rotating shaft 23 is clamped between the two buffer pads 39;

Due to the limitation of spiral spring 272, when the initial monitoring angle of monitoring device 30 needs to be adjusted, it can only be achieved by adjusting the fixed angle of monitoring device 30 on rotating shaft 23. When the initial angle of the monitoring box 32 in the monitoring device 30 needs to be adjusted, the locking sleeve 31 needs to be in a release state, and the locking sleeve 31 is clamped when the initial angle is adjusted to be in a proper state. The laser emitting device, the laser receiving device, the signal processing device, the image acquisition device and the data real-time uploading device are all arranged in the monitoring box 32.
