There is no need to contact the detection probe 222, thereby reducing the possibility of damage. The outer surface of the connecting column 22 is fixedly connected with a conical block 223, and the inner wall of the telescopic sleeve 2 is slidably connected with a conical clamping block 25. By setting the telescopic sleeve 2, specifically by installing the detection probe 222 inside the telescopic sleeve 2, the detection probe 222 is protected, and the detection probe 222 is not easily damaged, thereby saving costs. The rotating rod 21 is rotated counterclockwise to make the detection probe 222 slide out of the telescopic sleeve 2, and the detection probe 222 can be extended to detect the inside of the liquid or object, and the use method becomes more diverse. The back of the rotating rod 21 is fixedly connected with a rotating block 211, and the front of the rotating block 211 is fixedly connected with a connecting rod 213. Rod 212, the back of connecting rod 212 is fixedly connected with sliding block 213, by rotating the rotating rod 21 to drive the rotating block 211 to rotate, the two connecting rods 212 are moved, and the two sliding blocks 213 slide away from each other on the inner wall of the telescopic sleeve 2, the left side of the conical clamping block 25 is fixedly connected with a conical bar 251, the conical bar 251 contacts the inner wall of the conical block 223, and the fixing effect is better and more stable by embedding the conical bar 251 into the conical block 223, the right side of the conical clamping block 25 is fixedly connected with a connecting rod 24, the outer surface of the connecting rod 24 is wound with a spring 241, and the outer surface of the connecting rod 24 is slidably connected with the inner wall of the fixing ring 243, when the conical clamping block 25 moves toward the fixing ring 243, the connecting rod 24 slides in the fixing ring 243, and will not affect the conical The movement of the clamping block 25 can squeeze the spring 241. The left and right sides of the spring 241 are fixedly connected to the left side of the fixing ring 243 and the right side of the conical clamping block 25 respectively. The spring 241 can squeeze the spring 241 when the conical clamping block 25 moves toward the fixing ring 243. When the squeezing force disappears, the conical clamping block 25 returns to its original position due to the resilience of the spring 241. By setting the conical strip 251, specifically by moving the conical block 223 upward, the conical strip 251 is also squeezed, so that the conical strip 251 is inserted into the notch of the conical block 223.

When it is necessary to insert the detection probe 222 into the liquid or the object for temperature and humidity detection, the rotating block 211 is driven to rotate by rotating the rotating rod 21 counterclockwise, so that the two sliding blocks 213 move away from each other, and the connecting rod 24 is driven to move together, so that the conical clamping block 25 is separated from the conical block 223, and the conical bar 251 leaves the notch of the conical block 223, and the fixation of the conical block 223 is cancelled, so that the detection probe 222 slides out from the inside of the telescopic sleeve 2, and the connecting column 22 does not fall from the inside of the telescopic sleeve 2 by the limiting rod 23. The temperature and humidity of the liquid or the object can be detected by exposing the detection probe 222. When the detection is completed, the push rod 221 is pushed to move upward to drive the connecting column 22 to move together When moving, the conical clamping block 25 will be squeezed to the right through the conical surfaces at the top of the conical block 223 and the bottom of the conical clamping block 25, so that the conical block 223 continues to move upward, and the conical strip 251 will also be squeezed during the movement until the notch in the conical block 223 is aligned with the conical strip 251. After alignment, the conical clamping block 25 will be pushed toward the conical block 223 due to the elastic force of the spring 241, so that the conical strip 251 is inserted into the notch of the conical block 223, and the connecting column 22 is fixed. By installing the detection probe 222 inside the telescopic sleeve 2, the detection probe 222 can be protected when detecting the ambient temperature, and the detection probe 222 will not be damaged due to external reasons. The detection probe 222 is protected, and the detection probe 222 can also be extended to detect the inside of the liquid or object, and the usage method becomes more diverse.
