The thing that drops that salvaging nozzle alignment is needed to salvage, handle, makes piston be moved towards the direction away from fishing socket then up, because
For support column long enough, during piston movement, negative pressure can be formed so that fall to the direction air-breathing of support column by salvaging nozzle
Junk is firmly adsorbed in fishing socket；Compared with prior art by the way of electromagnetic adsorption drops thing, the utility model uses gas
Flowing mode structure is simpler, economic and environment-friendly.The fisher, which can also be used to extracting the column cap for being stuck in shaft bottom, to drop thing, logical by salvaging
Hole is vertically blocked column cap and dropped thing, and will salvage via design is that diameter subtracts on axis towards the dimension linear close to support column
Small structure so that the column cap that the utility model can block different-diameter drops thing, has widened applicable model of the present utility model
Enclose.At least two crotches are additionally provided with fishing socket bottom, the inner concave of the crotch points to support column, and crotch can be used for catching on
Rope form junk so that the utility model shorter to tiny, length drop thing or can be stuck in well while rope form junk is caught on
The column cap at bottom, which drops, thing while to be salvaged, and improves salvaging efficiency.
Preferably, at least one set of support bar limit base, each support bar limit are additionally provided with the support column internal cavities
Position seat includes two arc dops, and the arc dop is symmetrical on the center line of support column, the outside wall surface of each arc dop
Fixed with support column internal cavities, the bar wall of internal face and support bar matches.Further, support bar and sky inside support column
There is gap between chamber, the utility model sets at least one support bar limit base to play spacing work to the direction of motion of support bar
With avoiding support bar from rocking influences to salvage effect and cause piston wear.
Preferably, the cushion rubber layer of annular is additionally provided with the top end face of the support column.Further, in push-and-pull
During handle, set cushion rubber layer to protect the hand of people, avoid striking support column and injured.
Preferably, anti-skidding protective case is also cased with the outside of support column, the anti-skidding protective case is close to support top end.Enter one
Step, the setting of anti-skidding protective case can strengthen the frictional force between people's palm of the hand and support column, avoid rubber sleeve by the utility model
Drop.
The utility model compared with prior art, has the following advantages and advantages：
A kind of pneumatic oil underground fishing tool of the utility model, a center line and support column are provided with support column bottom
The fishing socket that overlaps of center line, be provided with a salvaging through hole in the fishing socket, the salvaging through hole with it is empty inside support column
Chamber communicates, and the diameter for salvaging through hole reduces on axis towards the dimension linear close to support column, causes the thing that drops using into negative pressure
Firmly adsorb in fishing socket；At least two crotches are additionally provided with fishing socket bottom, the inner concave of the crotch points to support
Post, crotch can be used for catching on rope form junk；The utility model is applied widely, the advantages that salvaging efficiency high, be environmental and durable, production
Cost is low, is applicable to industrial mass production.
