Convex with at joint portion 21 on the inner headed face of sleeve pipe 213 1 ends and form ratchet 216, then form some leads 332 downwards, be arranged with a flexure strip 35 that cooperates with ratchet 216 on each lead 332 respectively from movable sleeve 33 upper surfaces;
In the joint portion 21 of lamp bracket bar 20 upper ends, also be provided with a torsionspring 34, this torsionspring 34 is set in the sleeve pipe 213, the one free end is fastened on the rear end face of dividing plate 211, another free end convexedly stretches in outside the front end face of sleeve pipe 213, then forms the draw-in groove 313 that cooperates with the free end of torsionspring 34 on the dividing plate 311 in the hypozygal portion 31 of intermediate lamp hack lever 30.
The specific embodiment:
At first lamp bracket is assembled by shown in the accompanying drawing, consider the flexibility that lamp holder rotates, only be provided with a movable sleeve 33 within the joint portion 11 of lamp holder bar 10 lower ends and the upper joint portion 32 of intermediate lamp hack lever 30, when desiring lamp holder is rotated, the lamp bracket bar 10 that only with hand will be connected with lamp holder is pulled, and lamp bracket 10 can drive and be sheathed on the movable sleeve 33 in it and rotate;
And consider that lamp holder and many lamp brackets all have certain deadweight on the base, if between the hypozygal portion 31 of joint portion 21 that is fixed in the lamp bracket bar 20 on the base and the intermediate lamp hack lever 30 that is connected with lamp bracket bar 20, a movable sleeve 33 only is set, the situation that the lamp bracket bar 10 that then is easy to intermediate lamp hack lever 30 to occur and links to each other with lamp holder drops under the gravity effect automatically, therefore, with be fixed in base on the hypozygal portion 31 of the intermediate lamp hack lever 30 that is connected of the joint portion 21 of lamp bracket bar 20 upper ends in not only be provided with movable sleeve 33, and convex with at joint portion 21 on the inner headed face of sleeve pipe 213 1 ends and form ratchet 216, then form some leads 332 downwards from movable sleeve 33 upper surfaces, be arranged with a flexure strip 35 that cooperates with ratchet 216 on each lead 332 respectively, in addition, also be provided with a torsionspring 34 in the joint portion 21, this torsionspring 34 is set in the sleeve pipe 213, the one free end is fastened on the rear end face of dividing plate 211, another free end convexedly stretches in outside the front end face of sleeve pipe 213, then form the draw-in groove 313 that cooperates with the free end of torsionspring 34 on the dividing plate 311 in the hypozygal portion 31 of intermediate lamp hack lever 30, when rotating the intermediate lamp hack lever 30 that links to each other with lamp bracket bar 20 forward, because 216 pairs of ratchets are set in stopping of flexure strip 35 on the movable sleeve 33, movable sleeve 33 can not rotate with intermediate lamp hack lever 30, like this, lamp bracket bar 30 will rotate, just not only need to overcome the frictional force between the inner headed face of hypozygal portion 31 of elastic tape 34 on the movable sleeve 33 and intermediate lamp hack lever 30, also must overcome the elastic resistance of torsionspring 36, and will make intermediate lamp hack lever 30 go back to original position the time, then because flexure strip 35 can be along ratchet 216 slips at this moment, add the elastic restoring force of torsionspring 36, lamp bracket bar 30 can easily set back, in addition, the rotation amplitude of intermediate lamp hack lever can be limited by the defining flange 214 and 314 on joint portion 21 and 31 inner sleeves 213 and 313.
And for interconnect interconnective intermediate lamp hack lever 30 by joint portion, then consider and conveniently to rotate, but can not too careless principle, within interconnective joint portion, touch and be provided with outside the movable sleeve 33, ratchet 216 and flexure strip 35 also are set simultaneously, in the time will rotating intermediate lamp hack lever 30 forward, because stopping of 216 pairs of flexure strips 35 of ratchet, intermediate lamp hack lever 30 can not at will rotate, have only when the power that makes its rotation is enough to overcome the frictional force of elastic tape 34 and the inner headed face of joint portion on the movable sleeve 33, intermediate lamp hack lever 30 could rotate, and at this moment, movable sleeve 33 is motionless.And when desiring to make intermediate lamp hack lever 30 to set back, pull intermediate lamp hack lever 30 backward, then the flexure strip 35 on 216 pairs of movable sleeves 33 of ratchet this moment unrestrictedly acts on, flexure strip 35 can slip over ratchet 216 when intermediate lamp hack lever 30 rotated, therefore, intermediate lamp hack lever 30 can drive the movable sleeve 33 that is sheathed in its joint portion easily and sets back backward together.
