Rock.
This utility model provides a kind of ground cutting tool, including cutting bit, drill holder, drill bit fixed block, spiral shell
Bolt and packing ring, described cutting bit is arranged on drill holder, and described drill holder includes shoulder, shank and shank end
End, described shoulder, shank and shank end are coaxial round bar and diameter is sequentially reduced, and the end face of described shoulder is provided with two symmetries
Pin-and-hole, be provided with wedge pin in pin-and-hole, the tip of described wedge pin extends beyond the end face of shoulder, during described shank end is provided with
Heart screwed hole, described drill bit fixed block includes that housing and shank pocket chamber, described shank pocket chamber are arranged in housing and two ends
Opening, the size in described shank pocket chamber coordinates with shank, shank tip dimensions, and shank is inserted into shank pocket intracavity, spiral shell
Bolt is screwed in screwed hole of centre, tights a bolt and makes the end face of wedge pin wedging drill bit fixed block, described bolt and drill bit fixed block
Between be provided with a packing ring.
Preferably, described wedge pin is welded in pin-and-hole.
Preferably, the hardness material of described wedge pin is more than the hardness of drill bit fixed block material.
The utility model has the advantages that: this utility model simple in construction, easy installation and removal, be effectively prevented cutting burr
Head rotational wobble in the course of the work, improves work efficiency, brings more economic benefit.
