The annular extrusion block 18 squeezes the arc plate 17, causing the extrusion plate 6 to tilt and squeeze the wooden stick 9 to fix the wooden stick 9. The moving distance of the nut 12 is adjusted according to the size of the wooden stick 9. Wooden sticks 9 of different sizes can be fixed, making it convenient for staff to replace the wooden stick 9, thereby improving the wide application of the tip-shaped combustible moisture content detection device.

[0027] This embodiment is further configured such that a thermistor 10 and a capacitive humidity sensor 11 are disposed within the wooden stick 9, pins of the thermistor 10 and the capacitive humidity sensor 11 are disposed on one end of the wooden stick 9, a slot 14 is disposed on the fixing block 16, the thermistor 10 and the capacitive humidity sensor 11 are inserted into the slot 14 via pins, and the slot 14 is connected to the data transmitter body 1;

[0028] A wooden stick 9 is used to simulate a natural environment. A thermistor 10 and a capacitive humidity sensor 11 are embedded inside the wooden stick 9 to measure the temperature and humidity of the wooden stick 9.

[0030] The data collected by the thermistor 10 and the capacitive humidity sensor 11 are transmitted to the data transmitter body 1 through the pins and the slot 14 .

[0031] This embodiment is further configured such that a stopper 8 is movably provided on the other end of the wooden stick 9, a pair of support rods 7 is provided on the stopper 8, the pair of support rods 7 are movably provided in the support block 4, a limit block 2 is respectively provided on the pair of support rods 7, a first spring 3 is respectively provided on the pair of support rods 7, one end of the first spring 3 is provided on the limit block 2, and the other end of the first spring 3 is provided on the upper wall surface of the support block 4;

[0032] The first spring 3 is a compression spring, which drives the stop block 8 to move away from the support block 4, controls the movement of the support rod 7, and drives the limit block 2 to move. The first spring 3 generates elastic force. After the wooden stick 9 is installed, the stop block 8 is released. The interaction force generated by the first spring 3 causes the limit block 2 to move to the initial position, causing the support rod 7 to move, and then the stop block 8 to be close to the wooden stick 9. When fixing the wooden stick 9, the pins of the thermistor 10 and the capacitive humidity sensor 11 are prevented from being disengaged from the slot 14, which may cause errors in the measurement results, thereby improving the installation efficiency of the wooden stick 9.

[0034] The second spring 20 is a compression spring. When the extrusion plate 6 tilts, it drives the arc-shaped slider 5 to move into the guide groove 19. The second spring 20 generates elastic force. When the annular extrusion block 18 moves away from the arc plate 17, the interaction force generated by the second spring 20 pushes the arc-shaped slider 5 to move, thereby restoring the extrusion plate 6 to its initial position.

[0035] This embodiment is further configured such that a plurality of conical blocks 15 are provided on the extrusion plate 6, and a plurality of the conical blocks 15 are provided on the wooden stick 9;

The plug-in installation method can facilitate the staff to install the wooden stick 9, improve the installation and replacement efficiency of the wooden stick 9, and thus improve the working efficiency of the tip-shaped combustible moisture content detection device. After the wooden stick 9 is installed, the block 8 is released, and the first spring 3 generates elastic force. The thermistor 10 and the capacitive humidity sensor 11 are inserted into the slot 14 through the pin, and then the wooden stick 9 is installed on the fixed block 16. The interaction force generated by the spring 3 moves the limit block 2 to the initial position, moves the support rod 7, and then makes the stop block 8 close to the wooden stick 9. When fixing the wooden stick 9, it prevents the pins of the thermistor 10 and the capacitive humidity sensor 11 from being separated from the slot 14, which causes errors in the measurement results, thereby improving the installation efficiency of the wooden stick 9. The drive nut 12 rotates clockwise to move the nut 12 toward the support block 4, driving the annular extrusion block 18 to move. The annular extrusion block 18 squeezes the arc plate 17, causing the extrusion plate 6 to tilt and squeeze the wooden stick 9. The wooden stick 9 is fixed, and the distance of movement of the nut 12 is adjusted according to the size of the wooden stick 9. Wooden sticks 9 of different sizes can be fixed, which is convenient for staff to replace the wooden stick 9, thereby improving the wide application of the moisture content detection device for tip-shaped combustibles. When detecting tip-shaped combustibles, the detection device is placed in the tested environment, and the wooden stick 9 is subjected to a 10-hour time lag treatment to make the moisture content of the wooden stick 9 the same as the moisture content of the tested vegetation. The equivalent substitution method is adopted to detect the moisture content of the wooden stick 9 through the thermistor 10 and the capacitive humidity sensor 11, and then detect the current environment. The moisture content of the tip-shaped combustible material under the environment, the extrusion plate 6 tilts and drives the arc-shaped slider 5 to move into the guide groove 19, and the second spring 20 generates elastic force. When removing or replacing the wooden stick 9, the driving nut 12 rotates counterclockwise to move the nut 12 away from the support block 4, driving the annular extrusion block 18 to move, and the annular extrusion block 18 is away from the arc plate 17. The interaction force generated by the second spring 20 pushes the arc-shaped slider 5 to move, so that the extrusion plate 6 returns to its initial position, and then the extrusion plate 6 is away from the wooden stick 9, which is used to loosen the wooden stick 9 and facilitate the staff to take out the wooden stick.
