As further describing for above-mentioned technical proposal:
The internal diameter of the ram pot is equal with the diameter of first piston.
As further describing for above-mentioned technical proposal:
The telescopic rod is provided with two altogether, and two telescopic rods are symmetrical along the vertical center line of support plate.
As further describing for above-mentioned technical proposal:
The piston cylinder is set perpendicular to ram pot.
As further describing for above-mentioned technical proposal:
The end of the threaded rod is welded with rotating swing arm easy to operation.
In the utility model, first, ram pot is welded with the top of base, and a side bottom of ram pot is communicated with piston The inside of cylinder, ram pot and piston cylinder is marked with hydraulic fluid, and the inside of ram pot is slided by first piston and strut Connection, by rotating threaded rod, second piston can extrude hydraulic fluid, and by pressure actuation to first piston, this When first piston uplink under the thrust of liquid, so as to stable control strut uplink, and then control the height of support Degree is changed, this lifting structure, and easy to adjust, uphill process is stablized, and the position height adjusted is more accurate, secondly, is led to The rotary action of fixing bearing is crossed, the horizontal level that can be supported frame is adjusted, meanwhile, pass through the rotary action of shaft, energy Enough adjust top plate angle position adjust, during angular adjustment, symmetrically arranged two telescopic rods can accordingly under Drop and rising so that it is more reliable and more stable to adjust process.
