Abstract

A lens assembly includes an adjustable lens assembly including a handle. A telescopic tube is inserted at one end of the handle. A threaded rod is disposed inside the handle at an end close to the telescopic tube. An end of the threaded rod away from the telescopic tube penetrates through an outer wall of the handle and is connected to a turn button. An end of the telescopic tube inside the handle is sleeved with a driven gear. A driving gear is embedded in a surface of the handle above the driven gear. The driving gear and the driven gear enable the telescopic tube to rotate, thereby adjusting a direction of an insertion head at one end. The threaded rod and the turn button enable the telescopic rod to move within the handle, thereby adjusting the insertion head at one end to stretch out or draw back.
