Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment: as shown in Figs. 1-5, a kind of flashlight that heat dissipation performance effect is good of the utility model, including middle cylinder 1, in
One end of cylinder 1 is connected with rotating cylinder 2, and rotating cylinder 2 is connected with pedestal 3 far from one end of middle cylinder 1, and middle cylinder 1 is connected far from one end of rotating cylinder 2
There is cooling lamp holder 6,6 periphery of cooling lamp holder is equipped with sheath 4, and sheath 4 is connected with lampshade 5 far from one end of middle cylinder 1.
Cooling lamp holder 6 includes lamp holder 61, and lamp holder 61 is fixedly connected with circuit board 62, circuit far from one end of middle cylinder 1
