Further, the fixed plate other side is flexibly connected by screw and No. two screw holes with wheel hub.
Further, there are three shape is in a row for the No.1 screw hole and No. two screw holes and screw.
Compared with prior art, the utility model has the following beneficial effects:
1. fixed plate is fixed on above wheel hub by No.1 screw hole and screw, when group is fixed in a group blade by needs
When knitting rotation, fixinig plate, which is moved down, makes the lock tooth of bottom side and the groove of blade bearing inner ring coincide makes sharf
Prevention operation is held, and locks and is further consolidated between tooth by reinforcing rib, prevents from falling off between lock tooth and groove, Yi Mianye
Piece bearing operation bring contingency.
It just coincide, and is provided with above fixed plate more with circular blade bearing inner ring 2. fixed plate position is set as fan-shaped
A lock tooth, lock teeth multiple in this way carry out identical with groove, improve locking effect, single lock tooth is prevented to be easy to fall off, unstable
Gu fixed plate is fixed by three screws of row and wheel hub so that it is convenient to installation and removal, and fixed plate can not also
With disassembling, as long as then when do not need that a group blade is fixed by fixed plate move upwardly through No. two screw holes with
Screw is fixed, and locking tooth at this time will leave between groove, and then blade bearing can continue to move to again, entire locking device
It is simple to operate, it is applicable in when suitable for installation and maintenance to group blade, the rotation of group blade when avoiding installation and when maintenance
Bring accident is rotated when inconvenience caused by turning and maintenance.
