[0002] A digital storage oscilloscope is a digital device with storage function that uses digital circuits for analog-to-digital conversion and uses a memory to memorize the pre-trigger signal. In addition to the functions of an analog oscilloscope, a digital storage oscilloscope also has functions such as waveform triggering, storage, display, measurement, and waveform data analysis and processing.

[0003] For example, the Chinese patent number CN212134791U is a digital storage oscilloscope with high stability. Compared with the prior art, the utility model can comprehensively protect the operation buttons by using a closed elastic membrane through the setting of a protective member, effectively preventing external dust from entering the inside of the oscilloscope body from the position of the operation buttons, avoiding the rust of internal parts by dust, and improving their service life. The elastic membrane can be disassembled through the card slot and the card block, which can be applied to different equipment and has a high use value. By setting a support member, compared with the prior art, holding the extension plate on the fixed block The oscilloscope body can be placed on the table top by rotating it upward to a position perpendicular to the side surface of the oscilloscope body, thereby effectively increasing the overall support area. The top of the threaded rod is held and rotated downward, thereby driving the adsorption plate to move downward. When it contacts the desktop, the air in the adsorption plate is gradually squeezed out, and the negative pressure generated by the adsorption plate is used to fix it on the desktop, thereby ensuring the stability of the oscilloscope body when it is placed, avoiding the phenomenon of people accidentally touching it and causing it to fall, and improving its safety in use. However, the setting of the protective part makes it inconvenient to operate the knob, and the operation of the adsorption plate is not simple enough. Therefore, a digital storage oscilloscope is proposed to solve the above problems. Utility Model Content

[0006] The interior of the knob is connected to a rotating ring, and the outer side of the rotating ring is connected to a membrane cloth;

[0007] The anti-displacement mechanism includes a mounting block, which is connected to the outside of the oscilloscope body, a spring is connected above the mounting block, a mounting rod is connected above the spring, an adsorption plate is connected below the mounting rod, and a handle is connected to the outside of the adsorption plate.

[0008] Furthermore, the first magnetic strip is rectangular and is located outside the knob.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The digital storage oscilloscope can connect the protective cover to the oscilloscope body through the first magnetic strip and the second magnetic strip, so that when the oscilloscope is not in use, the knob and the button can be protected. When the knob is turned, the knob rotates relative to the rotating ring, and the rotating ring and the film cloth will not affect the operation of the knob, and the film cloth can prevent dust from entering the interior of the oscilloscope body from between the knob and the oscilloscope body.
