[0031] Specifically, when it is necessary to adjust the operating height of the infrared thermometer 12, it is only necessary to rotate the screw rod 3. The rotation of the screw rod 3 will drive the movable rod 5 to move downward on the outside of the sliding rod 16. Since the infrared thermometer 12 is connected to the movable rod 5, the infrared thermometer 12 will also move downward, thereby realizing the adjustment of the operating height. When it is necessary to adjust the operating angle of the infrared thermometer 12, the T-bar 9 can be pulled to release the half-toothed ring 10 from limiting the gear 8. At this time, the hollow column 7 can rotate freely, thereby driving the infrared thermometer 12 to adjust the angle. When the angle is adjusted to a suitable position, release the T-bar 9, and the second spring 11 will release the squeezed potential energy to drive the half-toothed ring 10 to rebound and limit the gear 8. In this way, during use, the infrared thermometer 12 will not shake accidentally, thereby ensuring the accuracy of the measurement results.

The ends of the two limiting rods 204 that are far away from each other respectively penetrate the corresponding limiting holes 205. The size of the fixed column 201 matches the internal size of the hollow column 7.

[0033] Specifically, when the infrared thermometer 12 is damaged due to long-term use, it is only necessary to press the limit rods 204 on both sides. The squeezing force of the first spring 203 will drive the limit rods 204 to disengage from the limit holes 205, thereby causing the infrared thermometer 12 to be detached from the device. At this time, it is relatively simple to disassemble and replace the infrared thermometer 12, which not only improves the maintenance efficiency of the equipment, but also reduces the maintenance cost.

[0040] Reference Figure 1 and Figure 3 A switch 14 is fixedly connected to the left side of the front end of the infrared thermometer 12, and a display screen 13 is provided on the right side of the front end of the infrared thermometer 12;

[0041] Specifically, the operation of the infrared thermometer 12 can be controlled by the switch 14, and the display screen 13 can conveniently obtain the measured internal temperature of the concrete.

[0042] Working principle: When using the device, first fix the device at the desired position through the cooperation of the arc plate 17 and the bolt 18, then rotate the screw rod 3 to drive the movable rod 5 to move downward on the outside of the slide rod 16, and the infrared thermometer 12 will also move downward so that the use height of the infrared thermometer 12 can be adjusted, and then pull the T-bar 9 to drive the semi-toothed ring 10 to release the limit on the gear 8.

At this time, the infrared thermometer 12 can be removed, and it is relatively simple to disassemble and replace the infrared thermometer 12, thereby improving the practicality of the device.
