The specific embodiment

The utility model is further elaborated by embodiment below in conjunction with accompanying drawing:

Embodiment 1: a kind of light-emitting device comprises 4 joint button cells 2, little 5 bulbs 5, conductor wire 4, touch switch, box body; Described box body is a hollow circular cylinder 3, the diameter of the inside diameter of hollow circular cylinder 3 and button cell 2 is complementary just, be provided with an opening 33 in the front of described hollow circular cylinder 3, button cell 2 is opening 33 phase embeddings therewith just, on the position of the back side of described hollow circular cylinder 3 and opening 33 symmetries, offer an opening 32, the size of opening 32 is less than the size of opening 33, opening 32 and not embedding mutually of button cell.Also be provided with an opening 34 under the opening 33 of described hollow circular cylinder 3, described opening 34 is less than the size of opening 33, opening 34 and not embedding mutually of button cell.Described touch switch comprises loam cake 1 and bottom, loam cake comprises cathode contact 13, metal compression spring 14, disk 12, is located at the rotary handle 11 on the disk, cathode contact 13, metal compression spring 14 are located at the bottom of disk, cathode contact 13 is electrically connected with metal compression spring 14, metal compression spring 14 links to each other with the positive pole of button cell 2 by the through hole 31 that the top at hollow circular cylinder 3 offers, the bottom comprises that cathode contact, cathode contact are the top section that conductor wire is arranged on hollow circular cylinder 3.

Button cell has certain dilatability, 4 joint button cells utilize this characteristic, can pack in the hollow circular cylinder 3 by opening 33, order stack is added in box body endoporus 35 tops, and is not having under the external force effect, button cell can not spill from opening 33 again, but when needs are changed battery, can apply external force by opening 32 again, from opening 33, release button cell, when needing to take out other button cell, can apply external force by opening 34.
