[0002] Electronic information anti-interference devices are the best auxiliary tools for solving interference problems that occur during equipment operation. Currently, there are two main types of anti-interference devices: one is the amplification anti-interference method, which, in principle, cannot eliminate interference, but can effectively reduce the amplitude of interference signals; the other is the frequency shift anti-interference method, which can better solve interference problems. Therefore, anti-interference devices have been widely used.

[0003] The patent application number "202122505110.1" describes an "electronic information anti-interference device". This device, by setting up a lifting and stabilizing device, allows the lifting rod to move stably up and down under the action of the telescopic spring, positioning hole and first positioning pin, thereby adjusting the height of the entire anti-interference device and making the entire anti-interference device more flexible.

[0004] However, the applicant believes that the device has the following problems when in use: although the device can adjust the height of the electronic information anti-interference device, it can only be adjusted to a specified height and cannot be arbitrarily adjusted. In addition, the electronic information anti-interference device is fixedly installed on the top of the support plate and cannot be disassembled, which makes it inconvenient to disassemble and maintain the electronic information anti-interference device.
