先把插杆连接到送井/回收工具的下端螺纹上，然后再与扶正器，震击器，加重杆，绳帽从下到上依次连接好和送井时一样下放到位。向下震击，抓住锁定部分的鱼顶，同时插杆插入锁定部分，使锁定部分上张开的2个键块收拢，上提，重量增加则表明下方工具被抓住了，然后向上震击，打捞出锁定部分。当打捞遇卡时，可以通过向下震击剪断剪切销钉，让它的捞爪释放，与下端鱼腔结构脱离。取出打捞工具，换上更粗的钢丝绳再进行打捞。

First connect the inserting rod to the lower thread of the well sending / recovery tool, and then connect it with the centralizer, jar, weighting rod and rope cap from bottom to top, and put it in place as during well sending. Shake down and grasp the fish top of the locking part. At the same time, insert the rod into the locking part, so that the two key blocks opened on the locking part are closed and lifted up. The increase of weight indicates that the lower tool is caught, and then shake up and fish out the locking part. When the fishing is stuck, the shear pin can be cut by shaking down to release its fishing claw and separate it from the fish cavity structure at the lower end. Take out the fishing tool and replace it with a thicker wire rope before fishing.

First, connect the plunger to the lower thread of the well-running/recovery tool, and then connect it with the centralizer, jar, weighting rod and rope cap from bottom to top, and lower it into place as well as when running the well. Knock down, grab the fish top of the locking part, and insert the plunger into the locking part at the same time, so that the two open key blocks on the locking part are folded up, lifted up, and the weight increase indicates that the tool below is caught, and then knock up and fish out the locking part. When fishing is stuck, the shear pin can be sheared by downward shock, so that its fishing claw can be released and separated from the fish cavity structure at the lower end. Take out the fishing tool and replace it with a thicker wire rope before fishing.
