Bottom is the hollow revolving body structure that cross section is isosceles rectangular triangle.The ring body is internally provided with an annular installation
Slot, is uniformly arranged that there are six arc anticollision slots on the outer wall of the annular mounting groove, can prevent the back cover plate of sampler from existing
Cause back cover plate that cannot open completely with sampling the annular mounting groove inner wall generation dimensional interference of housing in opening procedure, it is described
Setting is evenly arranged in the annular mounting groove at inner wall there are one back cover plate locating slot on the inner wall of annular mounting groove
Six positioning cylinders, the ring body upper surface are evenly arranged between connector and circular chuck at circular chuck
Six arc grooves；
The sampling turntable includes turntable body, turntable blind hole, turntable cylinder, the outer diameter and annular mounting groove of the turntable body
Outer diameter it is equal, be uniformly arranged in the turntable body there are six turntable blind hole and turntable cylinder, the turntable blind hole and rotation
Bar lower end is interference fitted, and its diameter is equal with the diameter of rotating bar lower end, and the turntable cylinder coordinates with connecting rod via clearance,
And its diameter is equal with connecting rod through-hole diameter；
The sampling connecting rod includes con-rod only, connecting rod through-hole, arc connecting plate, cylindrical bore, and the con-rod only is equipped with
One connecting rod through-hole for being used to install turntable cylinder, and turntable cylinder can rotate in connecting rod through-hole, the arc connecting plate and company
Bar body is fixed together, and the free end of the arc connecting plate is set there are one cylindrical bore, between two arc connecting plates
Distance it is equal with the thickness of back cover plate；
The back cover plate includes back cover plate ontology, connecting pin mounting hole, positioning cylinder mounting hole, and the back cover plate ontology is six points
One of cylinder, be provided with a connecting pin mounting hole and a positioning cylinder mounting hole, the connecting pin mounting hole with it is fixed
Circle of position column mounting hole is arranged symmetrically on back cover plate ontology, and the connecting pin mounting hole is that cylinder leads to positioning cylinder mounting hole
Hole.
