The support component 11 can support the rubber post 8, ensuring that the rubber post 8 and the power cord 5 are closely fitted and limited.

[0026] The support assembly 11 includes a movable block 1101, which is slidably disposed inside the housing 7. A slide rod 1102 is fixedly provided on one side of the movable block 1101, and one end of the slide rod 1102 passes through the housing 7 and is fixedly connected to one side of the rubber column 8. A support spring 1103 is fixedly provided between the movable block 1101 and the housing 7. A movable column 1104 is fixedly provided at the middle of the top of the movable block 1101, and a guide block 1105 is fixedly provided at the middle of the movable block 1101. A section is provided in the middle of the housing 7 that connects with the guide block 1105. 05. A sliding guide groove; the support component 11 is provided, which uses the moving column 1104 to drive the moving block 1101 to move, thereby synchronously driving the slide bar 1102 and the rubber column 8 to move, so that the power cord 5 can be wound around the outside of the winding reel 3 for storage. Conversely, when the moving column 1104 is released, the return spring 1103 can limit the winding of the power cord 5, preventing the power cord 5 from becoming loose, and ensuring the neat storage and normal use of the power cord 5.

[0027] The top of the protective plate 10 is provided with a fixing component 9, which includes a magnetic strip 901. The magnetic strip 901 is fixedly installed on the top of the protective plate 10. The top of the magnetic strip 901 is magnetically connected to an iron sheet 902.

The surface of the oscilloscope body 1 is provided with a limiting slide groove 905 that slides with the limiting slides 903. A push plate 904 is fixedly provided at the bottom of one side of the protective plate 10, and the surface of the push plate 904 is provided with a groove. The fixed component 9, through the design of the push plate 904 and the notch, can drive the protective plate 10 to move under the action of the limiting slide bar 903 and the limiting slide groove 905, so that the protective plate 10 is pushed upward. Then, in combination with the magnetic strip 901 and the iron plate 902, the position of the protective plate 10 can be limited and fixed, thereby protecting the display screen 2, avoiding damage to the display screen 2 from external factors, and ensuring the normal use of the display screen 2.

[0028] One end of the power cord 5 is fixedly equipped with a plug 6, and the surface of the winding reel 3 is provided with a winding groove that cooperates with the winding of the power cord 5; the plug 6 is provided so that it can be plugged into the power source to provide power; the winding groove is provided so that the power cord 5 can be wound up.

[0029] A handle 12 is fixedly provided at the center of the top of the oscilloscope body 1, and the surface of the handle 12 is covered with an anti-slip sleeve. Four evenly spaced support feet 13 are fixedly provided at the bottom of the oscilloscope body 1. The handle 12 and the anti-slip sleeve enable convenient movement of the test equipment and provide an anti-slip effect when carrying it. The support feet 13 provide support for the oscilloscope body 1.

[0030] In use, place the oscilloscope body at the work location, extend the movable column 1104 to move the movable block 1101, slide bar 1102, and rubber column 8, moving the rubber column 8 away from the power cord 5. Remove the power cord 5 from the surface of the reel 3, connect the plug 6 to the power supply, and power on the oscilloscope. Next, use the push plate 904 to move the protective plate 10 downwards, exposing the display screen 2. Then, the operator uses the switch to turn on the oscilloscope, and the display screen 2 lights up. The oscilloscope body 1 can then be used. The oscilloscope body 1 can intuitively display the signal waveforms on the FMC bus, covering key parameters such as signal amplitude, frequency, and phase. Through in-depth analysis of these waveforms, technicians can accurately determine whether there are signal quality problems on the bus. After use, unplug the plug 6, and move the moving block 1101 again via the moving column 1104, which in turn moves the rubber column 8. At this time, the support spring 1103 retracts, and then the power cord 5 is wound up to the winding reel 3. After winding, release the moving column 1104. Under the reset and rebound of the support spring 1103, the wound power cord 5 can be limited, preventing the power cord 5 from becoming loose, ensuring the neat storage and normal use of the power cord 5. Finally, use the handle 12 to place the test equipment in a suitable position.
