Optical module
View Patent ↗An optical module includes a base, an upper housing, an unlocker and a handle. The unlocker is rotatably connected to the base. The unlocker has a lock catch for locking the optical module. The handle is rotatably connected with the base by way of a first rotating portion. The unlocker is configured to be driven by the handle to rotate and cause the optical module to be in a locked state or an unlocked state. 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. A distance from the second end to a rotation axis of the first rotating portion is less than or equal to a distance from the first end to the rotation axis of the first rotating portion.
