The lifting positioning mechanism includes a telescopic shell 1, a top support seat 9 is installed inside the shell of the telescopic shell 1, and two groups of telescopic gallows 5 are symmetrically connected on both sides of the support of the top support seat 9, and a plurality of groups of arm support brackets 6 are arranged and connected between the two groups of telescopic gallows 5, and each group of arm support brackets 6 is connected to the center of the arm shaft of the telescopic gallows 5. By utilizing the connection between the arm support brackets 6 and the telescopic gallows 5, the gallows components can form an integrated telescopic stretching structure, and the telescopic stretching stability is better, and the anti-interference ability to the outside world is stronger.

[0024] The two adjacent groups of arm supports 6 are connected by a telescopic joint 7. The telescopic joint 7 is a corrugated tube structure, and the telescopic joint 7 is made of PVC material. The arm supports 6 are integrally connected with the telescopic gallows 5. The arm supports 6 can be pushed and pulled up and down to drive the telescopic joint 7 to be telescopic and stretched in a fixed point. Then, under the synchronous extension and contraction of the telescopic gallows 5, the monitoring height of the security monitoring probe 4 can be flexibly adjusted and calibrated to adapt to the flexible and changeable installation environment on site.

Then, under the synchronous extension and contraction of the telescopic gallows 5, the monitoring height of the security monitoring probe 4 can be flexibly adjusted and calibrated at a fixed point. Synchronously, the opening and closing handle 12 can be pulled to pull the opening and closing guide rod 13 out of the locking sleeve 3, so that the locking gear seat 15 and the locking gear 11 are released from the locked meshing state. At this time, the rotating sleeve 2 and the rotating shaft 8 are used to rotate and fit together to push the locking sleeve 3 to rotate horizontally, so as to lock the security monitoring probe The monitoring direction of the security monitoring probe 4 can be flexibly adjusted and calibrated. After the calibration is completed, it is only necessary to loosen the opening and closing handle 12 and use the elastic force of the compression spring 14 to push the opening and closing guide rod 13 so that the locking tooth seat 15 and the locking gear 11 are meshed and locked again. The monitoring direction of the security monitoring probe 4 can be adjusted and adapted to adapt to the flexible and changeable installation environment on site. Then, the real-time monitoring characteristics of the security monitoring probe 4 are used to perform security monitoring of the on-site environment, and the monitoring content is transmitted to the monitoring display terminal to play a role in remote anti-theft monitoring, alarm and the like.
