Abstract:
This invention provides a diamond geological drill bit with an anti-slip feature, related to the field of drill bits. The drill bit includes a fixed ring sleeve with a shock-absorbing spring set on the inside, one side of which is fixedly connected to a baffle that is set against the inner surface of the fixed ring sleeve. The outer bottom side of the fixed ring sleeve is connected to a positioning sleeve, with a positioning upper block fixed above one side of the sleeve away from the ring, and a positioning lower block fixed at the lower end of the sleeve near the upper block. A rotating nut is set on the upper surface of the upper block, with a rotating threaded rod fixedly connected to the nut’s lower surface, passing through the upper and lower positioning blocks. The positioning cone head ensures that the drill bit maintains grip during rotation, preventing damage to the bit.
