The detection probe 4 and the VOC detector body 1 are used to detect the air. Pulling the protective arc plate 5 causes the elastic element 8 to undergo elastic deformation, locking the protective arc plate 5 and the VOC detector body 1 together. Under the force of the elastic element 8, the protective arc plate 5 abuts against the VOC detector body 1, thereby protecting the VOC detector body 1. When detection at a high place is required, the telescopic folding rod 11 is pulled horizontally, and the elastic element 1... 3. When elastic deformation occurs, the telescopic folding rod 11 drives the locking rod 10 to move, placing the locking rod 10 on the same straight line as the rotating sleeve 9.
