Connection, screw rod are set in second gear axis；The other end of screw rod is connect with support plate；Fluted, groove is set in support plate
It is inside movably set with limiting device, limiting device includes limit plate, and limit plate is movably arranged in groove.
Further, the lower end of limit plate is provided with spring, and the top in groove, which is provided with, limits determining for limit Board position
Position plate, the lower end of limit plate is movably set with positioning component.
Further, positioning component is set as positioning pin, and positioning component activity is interspersed on the supporting plate, the lower end of limit plate
It is provided with the slot being used cooperatively with positioning component.
Further, positioning pin is to be threadedly coupled with support plate.
Further, limit plate is arranged to L-type structure.
Further, guide post is provided between support rod and support plate, the bottom of support plate is arranged in one end of guide post
End, the other end are arranged in fixed plate.
Further, gusset is provided between bottom plate and support rod.
The utility model has the beneficial effects that the utility model provides a kind of weight-bearing activities supporting leg, structure is firm, adjusts height
It is convenient, while there are also position-limiting actions, it is practical.
1, when putting the structural member of narrow boards in support plate, the setting of limiting device can be effectively prevented narrow boards and break away from two
Fall；When relaxing the structural member of plate, limiting device can be contracted in groove, not influence the placement of wide plate.
2, by starting motor in the utility model, screw rod rotation is driven by first gear, second gear axis, to adjust
The height of support plate is saved, easy to use, control is precisely simple.
