The base inner surface is provided with rectangular channel；Four vertex of the rectangular channel extend through pedestal；In the rectangular channel
It opens there are four conduit on surface；Four conduit inner surfaces are sliding combined with supporting leg；One surface of rectangular channel is fixed with
Support rod；The support rod is located at rectangular channel center；The support rod week, side was fitted with ball bearing；The rolling
Pearl bearing week, side was combined with gear；One surface of pedestal is provided with annular groove.
Further, the supporting leg one side is fixed with slider bar；The slider bar week side and conduit inner surface it is sliding
Dynamic cooperation；The supporting leg one side is provided with the gear teeth；The gear teeth and gear engaged transmission；The supporting leg one end side is fixed
There is universal wheel.
Further, the one centre of surface position of gear is provided with through hole；It is described to run through internal surface of hole and ball bearing
All sides are fixedly connected；One surface of gear is fixed with handle；The handle week, side was rotatably assorted with annular groove inner surface.
Further, the sliding sliver transvers section is isosceles trapezoidal structure.
Further, described conduit one end is fixed with limited block.
The invention has the following advantages:
The present invention is driven by rotate gear, gear and gear teeth meshing, to drive four supporting leg moving telescopics, in a disguised form
Increase the bearing area of pedestal, keep the seat more stable when in use, reduce injury to personnel caused by seat overturns
Possibility, to increase the service life of seat.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
