The end of the screw propulsion rod other end is connected with horizontal force rod structure, and horizontal force application structure includes being connected to the end
Several horizontal force application rods in same level in portion.
Horizontal force application rod has 4, and 4 horizontal force application rods are in cross.
The end of horizontal force application rod is cased with rotating handles.
Horizontal force application rod is fixed on by connector on screw propulsion rod.
The both ends of screw propulsion rod are stud, and respectively in precession connector and rotating blade.
Support base upper end is provided with vertical positioning tube, and internal thread is provided in positioning tube, is provided on screw propulsion rod
Matched external screw thread.
Support base is tubular structure, and the diameter of positioning tube is less than the diameter of support base.
Compared with prior art, the utility model has technique effect beneficial below：
One kind provided by the utility model cuts native device, and the cutting shoe of support base bottom end is inserted into the soil body, and seat to be supported is solid
After fixed, screw blade is set to cut a part of smooth erecting bed on the soil body by rotating screw propulsion rod；The device is can
While reaching to laboratory apparatus installation requirement, there is simple in structure, easy to operate, easy to remove, lower-cost feature.
Further, it by the way that horizontal force application rod is arranged on screw propulsion rod, is imitated by the lever that horizontal force application rod generates
It answers, the rotation of more laborsaving realization screw propulsion rod.
Further, the both ends of screw propulsion rod are connect by stud with connector and rotating blade, realize activity even
The purpose connect is convenient for the maintenance and repairing of the device.
Further, positioning tube positions the precession direction of screw propulsion rod, prevents it from being sent out during precession
Raw direction offset.
