End face be engaged drilling rod be locked in inside drilling rod mounting hole.
It is machined with arc notch on the latch, the drilling rod mounting hole phase of the arc notch and latch chute position
Cooperatively form complete drilling rod mounting hole；The outer face of the arc notch is machined with chamfering.
The ring set is locked in female connector by spring collar.
The external diameter of the latch and the arc external diameter of spring mounting groove position are equal, and whole mistake is formed after cooperation
Cross circular arc.
The utility model has the advantages that：
Using said structure, when drilling rod is installed, it is only necessary to drilling rod is inserted into inside drilling rod mounting hole, makes the head of drilling rod
The chamfering of portion and latch is engaged, then rotates clockwise drilling rod, extrudes latch, and latch overcomes the bullet of wind spring under extruding force effect
Power is acted on, and along latch chute to the Slideslip where spring mounting groove, and then drilling rod is smoothly inserted into drilling rod installation
The bottom in hole, then drilling rod is rotated counterclockwise, the locating slot of drilling rod is engaged with the end face of latch, now wind spring extrudes latch
To high order end, and then drilling rod is locked.
When dismounting drilling rod is needed, drilling rod is rotated clockwise, extrude latch, latch overcomes wind spring under extruding force effect
Elastic force is acted on, and along latch chute to the Slideslip where spring mounting groove, and then pacifies the arc notch of latch and drilling rod
Dress hole is engaged, and latch is departed from the locking action to drilling rod, then pulls drilling rod, and then drilling rod is smoothly pulled down.
When needing to pull down latch, it is only necessary to pull down spring collar, then remove ring set, it is possible to pull out latch, and then
Realize the dismounting of latch.
