Embodiment
Illustrate the embodiment of the utility model below by way of specific instantiation, those skilled in the art can be by this theory
Content disclosed by bright book understands other advantages and effect of the utility model easily.The utility model can also be by addition
Different embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints with answering
With carrying out various modifications or alterations under the spirit without departing from the utility model.It should be noted that institute in following embodiments
The diagram of offer only illustrates the basic conception of the utility model in a schematic way, in the case where there is no conflict, following embodiments and
Feature in embodiment can be mutually combined.
Please refer to Fig.1-Fig. 5, the element numbers in attached drawing represent respectively：Connector 1, the first cavity 11, locking groove 12, brill
Bar body 2, the second cavity 21, groove 3, stop hole 31.
Please refer to Fig.1 and Fig. 2, the utility model provide a kind of plug-in type drilling rod, the plug-in type drilling rod includes several
Drilling rod unit, and be made of the head and the tail splicing of several described drilling rod units, the drilling rod unit includes connector 1 and drilling rod body
2, one end of the drilling rod body 2 is fixedly connected with the connector 1, and the other end of the drilling rod body 2 has can be with institute
The groove 3 that connector 1 matches is stated, when assembling the plug-in type drilling rod, the connector 1 of a drilling rod unit and another brill
The groove 3 of bar unit connects, and the rotation between the two neighboring drilling rod unit of connector 1 and the groove 3 the cooperation limitation is certainly
By spending, further, the connector 1 has locking groove 12, and the groove 3 has stop hole 31；Each drilling rod unit
Further include the stop bolt (being not drawn into figure) for fixing the two neighboring drilling rod unit.When two neighboring drilling rod unit coordinates
When, the connector 1 matches with the groove 3, the stop bolt and 31 phase of the locking groove 12 and the stop hole
Match somebody with somebody.The extending direction of the extending direction and the drilling rod unit of the stop bolt is perpendicular, and the stop bolt limitation is assemblied in one
The two neighboring drilling rod unit risen is moved along the drilling rod unit extending direction；When two neighboring drilling rod unit is dismantled
When, the active bolt is taken out, then the two neighboring drilling rod unit can be moved along the extending direction of drilling rod unit, into
And the drilling rod unit is taken out.Therefore the plug-in type drilling rod is not only convenient for grafting assembling, and colliery layer is seized under colliery, and
And when being safeguarded, easy to take out, reduce the workload of manual work, and drilling rod list can be completed in narrow and small environment
