At the same time, the reset second slide bar will drive the limit strip to press against the outside of the protective shell, so that the protective shell covers the outside of the glass bottle and the connecting pipe for protection.

[0017] Optionally, the second sliding rod is slidably connected to the second sliding groove, and the upper end of the second sliding rod is in contact with the lower end of the electromagnet.

[0018] By adopting the above technical solution, it is convenient to set the electromagnet so that the electromagnet can adsorb and limit the second sliding rod.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] The technical solution of the present application comprises a moisture meter body, a glass bottle, a baffle, a first slide bar, a protective shell, an electromagnet and a pull rope, which can enable the pull rope to drive the baffle plate to move downward so that the ventilation groove on the baffle plate is aligned with the air inlet pipe, thereby facilitating air intake during transportation of the moisture meter body, and can also separate the limit strip connected to the second slide bar from the protective shell when the second slide bar moves to the right, thereby facilitating detection operations by staff. When idle, the baffle plate can also block the edge of the air inlet pipe to prevent external impurities from adhering to the inner wall of the air inlet pipe, thereby affecting the detection air intake of the moisture meter.
