In addition, because this class decorating lamp base of a fruit and lamp socket all adopt the injection moulding of plastics material to process, adding it is that series connection is hung or combination inserts and constitutes decorative pattern use on lamp bracket, is by the also load-bearing of very thin electric wire serial connection, thereby, its lamp base of a fruit and lamp socket designs very thin, Gao Shiyi feels like jelly in temperature, and when temperature is very low, not only hard but also crisp, both be not easy to the separation between the lamp base of a fruit and the lamp socket, be unfavorable for application of force operation again, more be not easy to change fast bulb.

In addition, the lamp base of a fruit of existing ornament lamp and lamp socket the peg graft point of application and the gap of back no staff or instrument insertion, therefore, it is impossible thinking quickly and easily the lamp base of a fruit and lamp socket are separated.

The cluster of lamps, ornamental base of a fruit on a kind of Christmas, lamp socket buckling device are disclosed in No. 78210590 patent application case in Taiwan, the fastening structure that in this application case, has adopted the button button to combine with cramp, to guarantee the convenience that does not come off and split of lamp, but because the lamp base of a fruit and lamp socket itself are just very little, cramp that injects on them and button button be then littler not only to fasten not too conveniently, and problem is split in the hard brittle failure when existing temperature low.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and provide a kind of on the lamp base of a fruit and lamp socket design have and both be convenient to both convenient small decorating lamps that breaks away from the band screw structure that can make both strong bonded.

The purpose of this utility model is to be realized by following technical scheme, radially evagination has a clamp on the flange lower cylindrical section cylindrical of the lamp base of a fruit aperture of circle, with lamp socket endoporus that the lamp base of a fruit plugs together mutually in an annular slot that can fasten with clamp is arranged, with annular slot connect be one with the lamp socket aperture logical axial slide that slits, after the clamp of evagination is aimed at the axial slide on the lamp socket and is pressed down on the lamp base of a fruit, the lamp base of a fruit then can insert in the lamp socket endoporus, and then once with lamp base of a fruit axial rotation, clamp promptly snaps in the annular slot in the lamp socket endoporus, extracts the lamp base of a fruit out as need and only need oppositely repeat above-mentioned action and get final product.

Therefore remarkable result of the present utility model is:

The ingenious design of first clamp and annular slot, both guaranteed that the lamp base of a fruit combined securely with lamp socket and can not arbitrarily come off, and simultaneously both can have been broken away from demand and easily, especially be convenient to the replacing of bulb, have characteristics simple in structure, convenient and practical.

The flange at place, aperture helps the application of force of hand or instrument on the second lamp base of a fruit.
