And, on the circumferential surface of described column bottom, the position between upper connecting base and lower connecting base stamps out that a convex closure is arranged.

Thereby, when three legs launch laterally and lower connecting base when column moves down, the inside edge of lower connecting base can be limited in the top of convex closure because of the convex closure of conflicting, can not continue to move down, and column and the weight that is arranged on the parts of column top can press down three legs and upper connecting base naturally, at this moment, the relative column of leg and connecting rod is in plateau, entire bracket tends to balance, and three legs are obliquely installed, be that its second end lands respectively, its first end is erected column jointly, column with and the whole weight of top just support by these three legs.In the time of support need being taken in or is carried, first end and the upper connecting base of three legs can move up along column, like this, three legs and three connecting rods will be holded up thereupon, last folding fasciculation, press close to around column, so, upper and lower connecting base, three legs and three connecting rods have just been formed foldable base in the support.

For making three legs upon deployment, its first end and upper connecting base be stud location and prevent that accident from moving up relatively, avoid causing the entire bracket instability, the outer side surface of described upper connecting base, the position of the convex closure of corresponding column outer surface can be provided with a locking button, the middle part of this locking button is rotatably connected on this upper connecting base, be provided with a spring between the inner side surface of this locking button lower end and the outer side surface of upper connecting base, and the position of corresponding locking button upper end offers a through hole that passes for the edge, upper end of locking button on the described upper connecting base; This spring makes the upper end of locking button have the trend of passing the through hole on the upper connecting base and pressing close to the column outer surface all the time, like this, when upper connecting base and locking button when column moves down, after the edge, upper end of this locking button runs into the convex closure on column surface, can be provisional with length of spring compressed, stick up outside the edge, upper end of locking button and cross convex closure, afterwards, convex closure can't the continuation activity because of the inside edge, top that runs into upper connecting base, promptly, convex closure is limited between the edge, upper end of the inside edge, top of upper connecting base and locking button, at this moment, the relative column locking of whole upper connecting base, upper connecting base and leg just can not move relative to column; And need to contact when locking, only need press the lower end outer surface of locking button to the inside, the outwards perk of the upper end of locking button, convex closure and column move up and down relatively again for upper connecting base and locking button.

For making upper connecting base and lower connecting base structure lighter and handier, described upper connecting base periphery can be evenly equipped with three first projections, first end of every leg just is plugged in corresponding first projection and with this first projection and is rotatably connected, and described locking button is arranged on wherein between two first projections, the periphery of described lower connecting base also can be evenly equipped with three second projections, every connecting rod comprises two motion bars, first end of two motion bars just is rotatably connected in the both sides of corresponding second projection respectively, second end just is rotatably connected respectively in the both sides at respective leg middle part, so design, make whole base in light weight, the activity that is easy to base is folding.

The above-mentioned mode of being rotatably connected can adopt existing various technology, such as bearing pin connect, hinged, articulate or the like.

Compared with prior art, the invention has the advantages that: by setting at peripheral upper connecting base of column and lower connecting base, the setting that is rotatably connected of three legs and three connecting rods, formed a folding base being positioned at the column periphery, this base makes support in use, expansion can be stablized and stood, when support need be moved or take in,, and remain on the vertical rod periphery with base folding fasciculation, be beneficial to very much and move action, and significantly reduce accommodation space, use is more comfortable, hommization, simultaneously, after the folding, the packaging space of integral support is little, in light weight, also be convenient to the packing and the transportation of product, very practical.
