Specific implementation mode

Referring to figs. 1 to Fig. 4, a kind of desk lamp of rotatable flexible, including lamp holder 10, lamp bracket 20 and lamp cap 30, lamp bracket 20 Rear end can lateral rotation setting on lamp holder 10, lamp cap 30 is arranged in the front end of lamp bracket 20, and it is in circle that lamp bracket 20, which includes several, The expansion bracket 21 of arcuation, the radius of each expansion bracket 21 is equal, and each two adjacent expansion bracket 21 is movably connected and opposite can slide and stretch Contracting.In the utility model, lamp bracket 20 has been spindle rotationally arranged on lamp holder 10, so as to easily adjust lamp bracket 20 and setting The direction of lamp cap 30 on lamp bracket 20, each expansion bracket 21 are in arc-shaped and can be with respect to sliding extensions, so as to convenient The distance between lamp cap 30 and lamp holder 10 are adjusted, use is more flexible and convenient, without folding bending lamp bracket 20, is not easy tired It strains bad, shape is also more aesthetically pleasing.It is usually provided with light source and optical module in lamp cap 30, electricity is then usually provided in lamp holder 10 Source adapter, these are all common structures in the art, are not described further separately herein.

Locking device is provided on lamp bracket 20, locking device is used to each two adjacent expansion brackets 21 being fixed together to limit The opposite sliding of each two adjacent expansion bracket 21, can prevent expansion bracket 21 in use from voluntarily occurring influencing to use with respect to sliding, In the present embodiment, locking device is to be screwed onto lock-screw 40 on lamp bracket 20, and lock-screw 40 can be pressed on expansion bracket 21 And two adjacent expansion brackets 21 are locked together, certainly, in practical application, bolt etc. can also be used in locking device, and other are normal Locking mechanism, or the frictional force between two adjacent expansion brackets 21 can also be used to limit between two adjacent expansion brackets 21 Voluntarily opposite sliding.

One in each two adjacent expansion bracket 21 is the first expansion bracket, and another is the second expansion bracket, and the first expansion bracket is in pipe Shape, the second expansion bracket sliding be plugged in the inner cavity of the first expansion bracket and can be simple in structure along the first expansion bracket sliding extension, just In processing and assembly, certainly, in practical application, the second expansion bracket is also slidably arranged in the outside of the first expansion bracket.

In the present embodiment, lamp holder 10 and lamp cap 30 are electrically connected by power cord, and in a tubular form, power cord is threaded through expansion bracket 21 In the inner cavity of expansion bracket 21, can protection power source line, prevent power cord from being scraped and damaged then lead to leak current fault or disconnected It splits, it is also possible that the more regular beauty of the utility model shape.

Lamp cap 30 is spindle rotationally arranged on lamp bracket 20, convenient so as to the more flexible direction for adjusting lamp cap 30 It uses, in the present embodiment, lamp cap 30 has been spindle rotationally arranged in by a gimbal structure 31 on lamp bracket 20, simple in structure, can Adjust range wide, easy to use, in practical application, lamp cap 30 also other common connection types can be rotatably arranged by pivot joint etc. On lamp bracket 20, it is not limited to this.
