Practical electroencephalogram analysis recorder

The practical electroencephalogram analysis recorder comprises a bottom plate, supporting plates are installed on the two sides of the outer wall of the top of the bottom plate through bolts, a top plate is installed on the outer walls of the tops of the supporting plates through bolts, and installation plates distributed in a horizontal structure are welded to the two sides, close to the supporting plates, of the outer wall of the top of the bottom plate. Threaded rods are movably mounted on the outer walls of the adjacent sides of the mounting plates through bearings, the directions of threads at the two ends of the outer side walls of the threaded rods are opposite, moving grooves are formed in the outer walls, close to the bottoms of the threaded rods, of the bottom plates, adsorption plates are slidably connected into the moving grooves, and sliding plates extending into the adsorption plates are in threaded connection with the two ends of the outer side walls of the threaded rods.
