The adjustable drill bit breaker can be used for bits with various specifications, and the embracing force is high.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to an adjustable drill bit handler. Background technique [0002] The drill bit loader, also known as the drill bit shackle, is an auxiliary tool used for loading and unloading the drill bit during the drilling operation. In this way, the drill bit can be prevented from contacting the turntable when making and unloading, so as to protect the bit blade and cutting teeth, and improve the service life of the drill bit. Under normal circumstances, a ring of shackle grooves is reserved on the outer wall of the threaded joint on the upper part of the drill bit for clamping the drill bit loader and unloader in it. [0003] The prior art provides such a drill shackle, which includes a square base and two handles arranged on the upper end of the square base. The square base is provided with a U-shaped opening slot for inserting a drill bit; the square base There is also a movable front ba...
