[0002] Halogen leak detector refers to a leak detector that uses halogen (fluorine, chlorine, bromine, iodine) gas as leak detector gas. This type of instrument is divided into two categories: one is a fixed type (also called internal probe type) leak detector in which the sensor (i.e. probe) is connected to the inspected object; the other is a portable type (also called external probe type) leak detector in which the sensor (i.e. suction gun) searches outside the inspected object. Leak detector gases include Freon, chloroform, iodoform, carbon tetrachloride, etc., among which chloroform is the best.

[0003] Most halogen leak detectors are now equipped with electronic display screens, and the display screens are mostly exposed, so the display screens may be damaged due to collision with foreign objects during the movement and storage of the leak detector. Therefore, a halogen leak detector with a screen saver structure is needed. The display screen of the halogen leak detector can be shielded and protected by a cover when not in use, and the cover can be opened when in use, thereby improving the protection effect of the leak detector display screen.

A rectangular opening 12 is adapted to the slide bar 10, and a pressing block 13 is fixedly connected to the top of the slide bar 10. The setting of the pressing block 13 increases the force-bearing area of ​​the end of the slide bar 10, avoiding finger pain when the user directly presses the slide bar 10.
