Preferably, described first time short connecting rod is provided with first locking piece of long connecting rod after locking first.
Preferably, described second quadric chain includes second time short connecting rod, short connecting rod on second, long connecting rod before second, long connecting rod and the second extension spring after second, on this second time short connecting rod and first, short connecting rod is rotationally connected, the two ends of second time short connecting rod respectively with second before long connecting rod lower end and second after the lower end of long connecting rod be rotationally connected, on second the two ends of short connecting rod respectively with second before long connecting rod upper end and second after the upper end of long connecting rod be rotationally connected, the two ends of this second extension spring are connected with middle part and second time short connecting rod of long connecting rod before second respectively.
Preferably, the second locking piece of second time short connecting rod of locking it is provided with on described first on short connecting rod.
Preferably, on described short fork and second, short connecting rod is rotationally connected, and this is provided with the 3rd locking piece for locking short fork on short connecting rod on second.
Preferably, having farther included power line, this power cord accommodation is in the first quadric chain, the second quadric chain and short fork, and power line electrically connects with lamp body.
This utility model compared with prior art has clear advantage and beneficial effect, specifically, as shown from the above technical solution:
During use, the second quadric chain is acted on hands, the second quadric chain can be made to swing up and down relative to the first quadric chain, simultaneously it is also possible that the first quadric chain respect thereto swings up and down, to adjust upper-lower position and the angle of lamp body, and by adjusting the pendulum angle of short fork, the most also the pendulum angle of adjustable lamp body, realize the regulation of rising angle, this utility model simple in construction, attractive in appearance, firm, and easy and simple to handle, the adjustment of lamp body big swing angle can be realized, thus offer convenience to the use of user.
For more clearly illustrating architectural feature of the present utility model and effect, with specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.

Detailed description of the invention
Refer to shown in Fig. 1, that show the concrete structure of the preferred embodiment of this utility model, include base the 10, first quadric chain the 20, second quadric chain 30, short fork 40 and lamp body 50.
The lower end of this first quadric chain 20 is installed on base 10 swingably, this second quadric chain 30 is installed on the upper end of the first quadric chain 20 swingably, this short fork 40 is installed on the upper end of the second quadric chain 30, and this lamp body 50 is installed on the outer end of short fork 40.
Specifically, described first quadric chain 20 includes first time short connecting rod 21, short connecting rod 22 on first, long connecting rod 23 before first, long connecting rod 24 and the first extension spring 25 after first, this first time short connecting rod 21 is fixed on base 10, the two ends of first time short connecting rod 21 respectively with first before long connecting rod 23 lower end and first after the lower end of long connecting rod 24 be rotationally connected, on first the two ends of short connecting rod 22 respectively with first before long connecting rod 23 upper end and first after the upper end of long connecting rod 24 be rotationally connected, the two ends of this first extension spring 25 are connected with middle part and first time short connecting rod 21 of long connecting rod after first 24 respectively.Further, described first time short connecting rod 21 is provided with first locking piece 26 of long connecting rod 24 after locking first.
Described second quadric chain 30 includes second time short connecting rod 31, short connecting rod 32 on second, long connecting rod 33 before second, long connecting rod 34 and the second extension spring 35 after second, on this second time short connecting rod 31 and first, short connecting rod 22 is rotationally connected, the two ends of second time short connecting rod 31 respectively with second before long connecting rod 33 lower end and second after the lower end of long connecting rod 34 be rotationally connected, on second the two ends of short connecting rod 32 respectively with second before long connecting rod 33 upper end and second after the upper end of long connecting rod 34 be rotationally connected, the two ends of this second extension spring 35 are connected with middle part and second time short connecting rod 31 of long connecting rod before second 33 respectively, and, the second locking piece 27 of second time short connecting rod 31 of locking it is provided with on short connecting rod 22 on described first.
And, on described short fork 40 and second, short connecting rod 32 is rotationally connected, and this is provided with the 3rd locking piece 36 for locking short fork 40 on short connecting rod 32 on second.
In addition, farther include power line 60, this power line 60 is accommodated in first quadric chain the 20, second quadric chain 30 and short fork 40, and power line 60 electrically connects with lamp body 50, and this lamp body 50 includes lampshade 51 and the light source (not shown) being arranged in lampshade 51.
