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 has clamping close device that can make both strong bonded that breaks away from.

The purpose of this utility model is to be realized by following technical scheme, the then vertical again protruding card handle down of the first level that on aperture flange on the lamp base of a fruit of circle, is fixed with, evagination has a degree of lip-rounding draw-in groove on the lamp socket cylindrical that plugs together with the lamp base of a fruit, when the lamp base of a fruit inserts lamp socket, the lower convex section of card handle is also along with being inserted in the degree of lip-rounding draw-in groove, the lamp base of a fruit and lamp socket can not be come off arbitrarily, when the card of ejection card handle lower end upwards along the time, then can be with the lamp base of a fruit by easily deviating from the lamp socket.

Therefore remarkable result of the present utility model is:

The ingenious design of first card handle and draw-in groove had both guaranteed that the lamp base of a fruit combined securely with lamp socket and can not arbitrarily come off, and the while can make both break away from demand easily again, especially is convenient to the replacing of bulb, has characteristics simple in structure, convenient and practical.

Second blocks the design of handle and draw-in groove, is convenient to the application of force of staff or instrument.

The 3rd card handle has the characteristics of strain, helps withdrawing from or enter and the engaging of draw-in groove.
