The rear end of the display screen 1203 is made of iron. The front end of the instrument housing 1 is equipped with multiple buttons 13. The rear end of the instrument housing 1 is equipped with a support frame 602 for easy adjustment and placement. When the display screen 1203 needs to be replaced, the display screen 1203 is removed from the screen placement slot 12 by placing a finger in the buckle slot 1205 and then applying pressure to the fixing plate 1206. The new display screen 1203 is placed in the screen placement slot 12 and attracted by the magnet 1201. The conductive sheet 1202 and the conductive groove 1204 are inserted into each other to form an electrical connection and display signal. The protective sleeve 3 can protect the outside of the device. The device can be placed and adjusted by adjusting the components on the adjustment slot 6.

[0023] Please see Figures 1-2 In this embodiment, a hook 2 is fixed to the upper end of the outer wall of the instrument housing 1. The upper end of the protective sleeve 3 is provided with a first groove 301 and a second groove 302. The hook 2 extends through the second groove 302 to the outside of the protective sleeve 3. A rope can be used to pass through the hook 2 to form a hanging rope buckle structure. The upper end of the instrument housing 1 is provided with a ventilation groove 4. A dustproof net 5 is provided on the ventilation groove 4. The dustproof net 5 on the ventilation groove 4 can be used to monitor temperature and humidity while performing dust prevention work.

[0024] Please see Figures 3-6In this embodiment, a control groove 8 is provided at the rear end of the instrument housing 1. Threaded sleeves 801 are fixedly connected to the four corners of the front end of the inner wall of the control groove 8. Screws 804 are threaded onto the threaded sleeves 801. A mounting plate 9 is placed at the rear end of the four threaded sleeves 801. A third groove 10 is provided through the four corners of the front and rear ends of the mounting plate 9.
