405, the elastic edge 1002 of the back locking slot 1001 of slope driving rolling center seat 100 of latch segment 405, make rolling center seat
100 are close to one side, meanwhile, top locking nut 401 tenses rolling center seat 100, rolling center seat 100 is close to positioning
The locating surface of platform 500.
（2）Top part upper and lower small range moving process in pilot hole 1003：
As shown in figure 3, manually lift handle 301, the horizontal small 601 and second horizontal ramuscule of fulcrum of first on handle 301
Axle 602 promotes guide sleeve 209 to move upwards together, and the upper surface of guide sleeve 209 promotes bearing pin 207, and bearing pin 207 is before this by rising
Covering path section 202 drives ringfeder integrally up, meanwhile, second spring 206 makes thimble 203 when ringfeder above carries, using spring force
The inside of footpath section 201 big with ringfeder is unclamped, and ringfeder is moved freely；Ringfeder integrally up certain distance when ringfeder path section
202 upper end touches flange nut 208, by flange nut 208 drive thimble connecting shaft 204 and thimble 203 together on
OK.When being up to certain position, axle is loaded onto, axle end center hole withstands thimble 203, unclamp handle 301, now to pressing closer pin 203
First spring 205 promotes the compression big footpath section 201 of ringfeder descending, ringfeder is held thimble 203 tightly.
The utility model mainly has advantages below：
（1）For top rotation in high speed rotation or clamping process or rock and axially or radially offset problem occur, root
According to ringfeder principle, moved using ringfeder in guide, ringfeder contacts with top for pine, when ringfeder and top be moved to require position
Shi Liyong springs ringfeder holding is top, while makes ringfeder and guide tight fit, it is ensured that top not rocked when rotating.
（2）Ringfeder with made between top with setting spring ringfeder and it is top together with move up when keep top and match somebody with somebody with ringfeder pine
Close, ensure that ringfeder moves freely.
（4）Inclined-plane tension mechanism is set up between chute and guide block, makes rolling center is overall can after movement in chute
Against a locating surface, realize that rolling center is overall has good repetitive positioning accuracy in large-scale movement.
（5）The problem of being brought for high-frequency using clamping inconvenience, moved up and down using manual handle control is top, it is full
Sufficient axle clamping repeatedly in the range of.
