The elastic element can be a spiral spring or a rubber band. When the lead wire 12 needs to extend out of the storage container, only a pulling force is applied to overcome the elastic force generated by the elastic element, so that the wire spool rotates against the preset direction, and the lead wire 12 wound on the wire spool is released, thereby adjusting the distance between the lamp body 11 and the lamp cap 10. When the required distance is adjusted, the wire 12 can be loosened, and at the moment, the ratchet wheel is clamped by the ratchet wheel, so that the ratchet wheel cannot rotate, and the wire spool cannot rotate, and therefore, the length of the wire 12 which is extended out and stored easily at present can be fixed. If readjustment is needed, the ratchet release button can be pressed down to lift the ratchet, the resistance of ratchet rotation disappears, the wire spool rotates along the preset direction under the action of the elastic element, so that the wire 12 is wound on the wire spool more, and the length of the wire 12 extending out of the storage container is shortened.
In a preferred embodiment, the ratchet release button may be provided with an operating end that exposes a surface of the lamp cap 10 for easy manipulation by a user.
