[0036] For the corner position table of the present utility model, the lead screw 4 drives the thrust plate 3, and the thrust plate 3 then forces the movable connection plate 5 to move along the thrust inclined surface 31, thereby driving the bearing plate 6 to perform a pitching motion relative to the base plate 1 around the upper side of the support plate 2, realizing the adjustment of the pitching angle of the bearing plate 6 within a certain range; the load capacity of the whole structure is strong, and it can carry equipment with a large weight, effectively breaking the application limitations of the corner position table.
