High toughness through-cable drill pipe
By introducing a fixing plate, a plug-in plate, and a locking assembly into the high-toughness cable drill pipe, the problems of insufficient torque and detachment caused by the threaded connection of the drill bit are solved, enabling rapid replacement of the drill bit and improving its torque resistance.

AI Technical Summary
Technical Problem
In existing high-strength, high-toughness center-through-cable drill rods, the drill bit and the second connecting ring are connected by threads, which causes the drill bit to be unable to bear large torques and is prone to falling off.
Method used
The design employs a fixed clamping plate, a plug-in clamping plate, and a locking assembly. The plug-in clamping plate engages with the fixed clamping plate, and the locking sleeve and locking screws enable quick replacement and fixation of the drill bit, enhancing the drill bit's torque resistance.
Benefits of technology
This enables quick drill bit changes and allows the drill bit to withstand greater torque during rotation, thus improving its stability and lifespan.
