Rank, the bottom surface of the flange are pressed on the top surface of the step.
In a preferred embodiment of the utility model, by several between the top surface of the flange and the buckle
Fastening screw connection.
In a preferred embodiment of the utility model, an adjustable column is provided on the top surface of the flange,
Knothole of setting the tone is provided on the buckle, the adjustable column passes through the adjustment hole, adjusts the fitted outside ball return to facilitate
Circumferential position.
In a preferred embodiment of the utility model, offered in the hole edge of the fitted outside ball return mounting hole
The edge of an at least card slot, the buckle side is inserted into the card slot.
In a preferred embodiment of the utility model, symmetrically opened in the hole edge of the fitted outside ball return mounting hole
If the edge of the symmetrical two sides of buckle is inserted into corresponding card slot there are two card slot.
In a preferred embodiment of the utility model, it is each provided on the edge of the symmetrical two sides of buckle
Positioning protrusion, is provided with positioning groove in the hole edge of each card slot, the positioning protrusion be inserted into the positioning groove into
Row positioning.
Due to using technical solution as above, the fitted outside ball return in the interior circulation ball-screw of the utility model is solid
Rationally, processing easy to produce, fitted outside ball return dismounts convenient, assembly efficiency for fitted outside ball return design in Dingan County's assembling structure
Height can effectively avoid fitted outside ball return from loosening, fall off convenient for Automated assembly and fitted outside ball return installation reliability height.
