[0002] For example, a security infrared detector mentioned in announcement number CN202222081414.4 is a security infrared detector. The security system is mainly installed in roads, shopping malls, banks, shops, factories, homes and other places. It is used to monitor the situation in the above places. The infrared detector is the core component of the security system. The traditional security infrared detector is fixed to the wall by a number of expansion screws. When adjusting the height position, the infrared detector needs to be removed from the wall and reinstalled, which makes the height adjustment operation of the infrared detector more cumbersome, affecting the convenience of use;

[0003] The solution is to use a pull block to pull the positioning column so that the positioning column is separated from the positioning hole, the spring contracts, and the limit sleeve is lifted and lowered on the rectangular column until the infrared detector body is adjusted to the required height position, and the spring is used to drive the positioning column to reset so that the positioning column is inserted into the corresponding positioning hole on the rectangular column, and the height position of the infrared detector can be adjusted;

[0004] With respect to the above-mentioned related technologies, the inventor believes that when adjusting the height of the detector, the device needs to use multiple bolts for disassembly and installation, and the overall adjustability is poor. There are problems such as low adjustment accuracy and limited adjustment range, which limits the performance and application range of the infrared detector;
