• a handle comprising a handheld portion and a cantilever, wherein the handle is rotatably connected with the base by way of a first rotating portion, and the unlocker is configured to be operatively driven by the handle to rotate and cause the optical module to be in a locked state or an unlocked state;
• wherein when the optical module is in the locked state, a first end of the handheld portion is further from a top surface of the upper housing than a second end of the handheld portion from the top surface of the upper housing, and a distance from the second end of the handheld portion to a rotation axis of the first rotating portion is less than or equal to a distance from the first end of the handheld portion to the rotation axis of the first rotating portion.
