[0002] With the development of society, people pay more and more attention to environmental quality, especially the particle dust index in the atmosphere. A dust detector is an instrument used to measure the concentration of particle dust in the environment. It is mainly composed of a detector body, a display screen, an operating panel and a detection head. A dusty environment can cause great harm to operators and safe production, so it is necessary to detect the dust content in the environment.

[0003] Existing dust detectors are divided into fixed and portable types. In order to be more convenient for actual use, most dust detectors are handheld and portable. However, handheld operators can only hold it with one hand, which limits the operator's work and makes it impossible to place the dust detector stably. After long-term use, the portable dust detector is prone to falling and damage, affecting actual use. Utility Model Content

There are two moving blocks 6, which are symmetrically distributed on both sides of the bidirectional screw rod 3. A limit groove is provided on the side of the moving block 6. The moving block 6 is slidably connected to the limit plate 5 through the limit groove. The hand wheel 4 is turned to rotate the bidirectional screw rod 3, so that the moving blocks 6 and the card slot 10 on both sides move toward each other synchronously until the card slot 10 clamps the operator's arm or the required fixed rod, so as to solve the problem that the detector is easy to slip and fall during use, and at the same time free the operator's hands to improve the convenience of use.
