A moving device is disclosed. The moving device includes a first lens barrel, a second lens barrel, a shutter module, a pushing lever, a flexible element, and a third lens barrel. The first lens barrel includes an upper edge and a groove which is at the upper edge. The second lens barrel is sleeved within the first lens barrel. The shutter module is disposed on the second lens barrel. The pushing lever includes a first end and a second end which is fixed within the groove of the first lens barrel. The flexible element is disposed besides the pushing lever for pushing the pushing lever. The third lens barrel is sleeved outside the first lens barrel. The third lens barrel includes a convex block. When the first lens barrel, the second lens barrel, and the third lens barrel are extending, the flexible element pushes the pushing lever for enclosing the pushing lever within the groove of the first lens barrel; when the first lens barrel, the second lens barrel, and the third lens barrel are stowing, the convex block pushes the pushing lever out of the groove of the first lens barrel.
