Detailed Description

The core of the utility model is to provide GCS cabinet auxiliary spanner.

The present invention will be further explained with reference to the accompanying drawings:

when the device is used, the two ends of a handle 1 are respectively provided with a circle center outer hexagonal screwing head 2 and a circle center inner hexagonal screwing head 2, the device is in screw connection and fixation with the handle 1 through a connecting layer 4 of the screwing head 2, three linear guide rails 7 are arranged in a moving layer 5 of the screwing head 2, included angles of the three linear guide rails 7 are 60 degrees and intersect at the circle center, the linear guide rails 7 are circular through holes in the moving layer 5, a corresponding number of transmission lead screws are arranged in the circular through holes, the end faces, far away from the circle center, of the transmission lead screws are provided with straight grooves 11 along the axis, two ends of the linear guide rails 7 are fixedly provided with bearings, the bearings are fixedly connected with the transmission lead screws, isosceles trapezoid blocks 8 of a working layer 6 are vertically welded on the transmission lead screws, the side faces of the isosceles trapezoid blocks 8 are connected with the moving;

as shown in fig. 2: in protruding 10 twist head 2, 6 centers in working layer still are fixed with a regular hexagon, it has six isosceles trapezoid blocks 8 to distribute all around, trapezoidal hypotenuse is 60 with the contained angle of bottom surface, each trapezoid block all can move the adjustment position through drive screw's straight flute 11, get minimum position after the regulation and form a whole for six isosceles trapezoid blocks 8 polymerization and with regular hexagon, get maximum position after the regulation and scatter for six isosceles trapezoid blocks 8 outside edge equidistance, its extension line forms a great regular hexagon space, position through adjusting isosceles trapezoid block 8, can change the regular hexagon space that forms at will, so that the size of the different nuts of adaptation.
