The linking pipe fitting 14 of downside is that the following threaded portion 1411 with its connection tube 141 is screwed together in chassis screw rod 12, closely is resisted against the end face location on chassis 11 again with the bottom surface of described connection tube 141; Middle linking pipe fitting 14 is that the following threaded portion 1411 with its connection tube 141 is screwed together in downside and is connected pipe fitting 14 it is connected first halves location of screw rods 142, and the linking pipe fitting 14 of upside is to be connected pipe fitting 14 in the middle of the following threaded portion 1411 with its connection tube 141 is screwed together in it is connected first halves location of screw rods 142;

The linking screw rod 142 that is connected pipe fitting 14 at upside screws togather a universal joint group 15, it comprises that one takes over 151, an one universal screw rod 152 and a nut 153, wherein taking over 151 is vertically disposed bodys, it forms the less screwed pipe portion 1511 of a diameter at the top, outer peripheral face in screwed pipe portion 1511 forms a screw thread 1512, again at the top of screwed pipe portion 1511 inner peripheral surfaces with around form form an inclined-plane 1513, form one in the bottom of taking over 151 inner peripheral surfaces and take over threaded portion 1514, be screwed together in first halves location that upside is connected pipe fitting 14 its linking screw rods 142 to take over threaded portion 1514, form one polygonal 1515 at the outer peripheral face of taking over 151 again;

Described universal screw rod 152 is vertically extending screw rod bodies, it forms a diameter is the head 1521 of sphere in the bottom than big and side face, place the inclined-plane 1513 of taking over 151 tops with head 1521, in universal screw rod 152, run through vertically again and form a through hole 1522, described nut 153 is the screw threads 1512 that are screwed together in screwed pipe portion 1511, periphery at nut 153 tops protrudes out inwardly and forms a catch flanges 1531, be buckled in head 1521 location, top side on every side with catch flanges 1531, in a side of catch flanges 1531 inner peripheral surfaces and offer the recess 1532 of a U-shaped towards the side, its width is the width greater than universal screw rod 152.

One lamp holder structure 20, be provided with a lamp holder body 21 that forms opening forward, in lamp holder body 21 bottoms in conjunction with the stacker 22 that extends under one day, bottom vertical at stacker 22 and lamp holder body 21 runs through one in conjunction with screw 23, be positioned universal screw rod 152 to screw togather in conjunction with screw 23, periphery at lamp holder body 21 front ends extends a clasp 211 forward, its be circular ring body and at the adapter ring of outer peripheral face around being arranged with an embedding ditch 212, be embedded location one at embedding ditch 212 and fasten ring 24, it is the elastic ring body of annular, corresponding clasp 211 is provided with a lampshade 25, its buckle closure is around clasp 211, be arranged with one at the inner peripheral surface of lampshade 25 and buckle ditch 251, be buckled in the location, the outside that fastens ring 24 with button ditch 251.

The utility model removes aforementioned preferred embodiment, be to combine between the adapter threaded portion 1514 of lamp holder structure 20 and top side beyond the described universal joint group 15, also can be directly lamp holder structure 20 directly be screwed together in 1514 location, adapter threaded portion of top side in conjunction with screw 23, become that lamp holder body 21 is fixing can not to be rotated or the enforcement state of left and right beat, so change the utility model of structure is not limited at this.

When the utility model uses, please referring to Fig. 1 to Fig. 3, be that bulb is located in the lamp holder body 21, and electric wire penetrated by backguy ditch 113, make electric wire through chassis screw rod perforation 121, each connection tube 141, respectively be connected screw rod perforation 1421, take over 151 and through hole 1522 after, stretch at last and connect bulb in the lamp holder body 21, the utility model relies on backguy ditch 113, respectively is connected the setting that pipe fitting 14 and universal joint group 15 inside have hole, make electric wire can be through at inside and can not expose, can reach the result of use that the succinct and electric wire of outward appearance draws arrangement easily.

When using the utility model illumination, rely on the setting in universal joint group 15 joints, when adjusting lamp holder body 21 with the head 1521 original places rotation of universal screw rod 152, can make lamp holder body 21 towards different directions, perhaps make lamp holder body 21 with universal screw rod 152 left and right swings even swing in recess 1532 places, so change the angle of lamp holder body 21 skews, make things convenient for the user adjust 21 illuminations of lamp holder body towards the position; And because lampshade 25 is to be buckled in and fasten to encircle 24 mode and locate buckle ditch 251, therefore when needing dismounting lampshade 25 to change the bulb of lamp holder body 21 inside, use that need not instrument just directly the application of force dismantle lampshade 25 in the mode of choosing, the operation that more changes the bulb is quick and convenient completely.

When needs change the height and position of lamp holder body 21, be to be connected the height that the pipe fitting 14 upper and lower group numbers that screw togather change lamp holder structure 20, as Fig. 4, shown in Figure 5, be by three groups of states that change two groups into the upper and lower linking pipe fitting 14 that screws togather of the utility model, the position that this moment, lamp holder was constructed 20 combinations can reduce, and can reach to reduce the adjustment effect that lamp holder is constructed 20 positions; When need the raise position of lamp holder structure 20 of environment for use, then the upper and lower linking pipe fitting 14 that screws togather is changed into more than four groups by three groups and get final product, the group number that can screw togather with user's meaning change linking pipe fitting 14 is adjusted very free.

More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
