AI Technical Summary
The positioning structure of traditional diamond composite drill bits cannot be flexibly adjusted, which limits the ability of the drill bit to drill deeper holes and makes it inconvenient to use.
An adjustable positioning device for diamond composite drill bits was designed. By setting an adjustable positioning sleeve and a locking block structure on the drill rod body, the positioning sleeve can be adjusted at different heights. Combined with springs and anti-slip teeth, the stability and flexibility of the drill bit are ensured.
This technology enables drill bits to operate with greater flexibility and stability at different depths, improving the convenience and operability of drilling operations.
