Beschreibung
Zusammenfassung:	The novel imaging lens focusing device is provided with a plurality of adjusting mechanisms, the adjusting mechanisms are detachably connected with a shell on the outer side of a lens, each adjusting mechanism comprises a small support, a rotating shaft and an adjusting piece, the small supports are connected with a circuit board, an insertion cavity is formed in the middle of each small support, and the rotating shafts are arranged in the insertion cavities and can rotate around the insertion cavities; one end of each adjusting piece sequentially penetrates through the rotating shaft, the small support and the circuit board, the other end of each adjusting piece is detachably connected with the shell on the outer side of the lens through a limiting mechanism, the adjusting pieces can move up and down relative to the rotating shaft, the small support and the circuit board, and when the distances of all the adjusting pieces relative to the corresponding circuit board are adjusted simultaneously, the lens moves
