Working and use methods：
Anchorage: While in progress the descent, stop pin is in the short track. When anchor is landed to a certain position, lift the rod string to a certain place then land it down so that control pin is switched to long track. After that slips are opened, blocked on casing.
Dis-anchorage: Lift the rod string, reset the slips.
Note:
Anchorage position must be kept away from casing coupling.
While taking off the lift sub, rod string can not be lifted up more than 0.2m to avoid accidently anchorage.
