During the installation process, the sensor may be installed and positioned inaccurately. This may lead to shaking during daily use after installation due to the length of use, thus affecting the effect of use. Utility Model Content

[0007] As a further improvement of the above scheme, the number of the positioning shafts is set to four, and the four positioning shafts are located at the bottom of the sensor mounting block. The number of the telescopic rods is set to eight, and the eight telescopic rods are grouped in two and distributed circumferentially on the inner wall of the lower fixed plate. The number of the push plates is set to four, and the four push plates are located at the ends of the telescopic rods. The push plate extension block is located below the spring, the telescopic rod is located below the sensor mounting block, and the lower fixed plate is located below the sensor.

[0008] Through the above technical solution, by arranging the spring, an automatic resetting function is played during the installation process, thereby completing the resetting of the front push plate.

[0016] The utility model completes the positioning of the sensor mounting block by arranging a positioning shaft, and the four positioning shafts under the sensor mounting block are plugged into the circular holes provided in the lower fixing plate. At the same time, during the plugging process, the inclined surface fixing block under the sensor mounting block follows and descends, and the arc surface of the inclined surface fixing block contacts the upper surface of the push plate. Due to the arc surface design, the push rod in front of the telescopic rod is pushed to move backward during the contact process, and the spring also moves backward.

At the same time, in each groove provided in the groove provided in the lower fixing plate, two telescopic rods and springs are placed, which are located on the back of the push plate.

The surface of the threaded ring is threadedly connected to the inner surface of the fixing ring, which is convenient for disassembly and installation. A motor is installed on the top of the inner surface of the fixing ring. The fan blades are driven to rotate by starting the motor to dissipate heat for the sensor below, and the heat can be discharged through a plurality of heat dissipation grooves opened on the surface of the fixing ring.
