The device has the advantages of simple structure, convenience in operation, time and labor conservation, wide application range, high reliability and lower cost. And dimple depth control is accurate. By redesigning and optimizing the structure size, the process fastening screws, the edges of the small steps of the opening frame or the nearby small step section bars are effectively avoided, the rivet nest cutting work of the supporting plate nut 9 in most narrow space areas and nearby small steps is adapted, the rivet nest cutting quality of the supporting plate nut 9 can be obviously improved, and the work efficiency is improved.
Example 2
The utility model provides a little step stop collar of narrow and small position dimple in space includes main shaft 1, the bottom of main shaft 1 is fixed with draws the nest and bores 8, the outside of main shaft 1 is provided with main shaft sleeve 5, main shaft sleeve 5's upper end outside is provided with adjusting collar 2, adjusting collar 2's below is provided with clutch 3, main shaft sleeve 5's outside is provided with little step position sleeve 6.
An annular spring 4 is arranged between the small step positioning sleeve 6 and the main shaft sleeve 5. Balls are arranged between the main shaft sleeve 5 and the main shaft 1.
