Connection more consolidates, is difficult to tumble, and reduces under heeling condition using the requirement to magnetic attraction；（3）Magnetic of the present utility model
Designed by special optimization the position of block and hydraulic motor：In three magnetic blocks the center of gravity of wherein one and the axis of main shaft with
And the axis co-planar of hydraulic motor, and this magnetic block is located at the both sides of main-shaft axis with hydraulic motor respectively, due to hydraulic pressure horse
The large percentage of whole device is accounted for up to weight, while above-mentioned magnetic block is the position of the fulcrum tumbled under heeling condition, therefore this sets
Meter ensure that the overall center of gravity of the present apparatus, away from fulcrum of tumbling, reduces the possibility for tilting and being tumbled when using, so as to enter one
Step is reduced under heeling condition using the requirement to magnetic attraction；（4）The utility model also defines total height for H and cutting diameter
For the proportion between D, so as to avoid, device center of gravity is too high to cause risk increase of tumbling.
