Head, the top movable of the cutter head are connected with link block, and point of a knife is fixedly installed at the top of the link block, the link block
Internal whorl is set with the threaded rod extended to inside link block, and the external fixing sleeve on the fixture block top is equipped with guard circle, institute
State cutter head outside open up it is fluted.
Preferably, the front of the fixture block offers elongated slot.
Preferably, the inside fixing sleeve of the guard circle is equipped with cutter head.
Preferably, the inside of the link block offers the first threaded hole, the first screw thread opened up inside the link block
The internal whorl in hole is set with threaded rod.
Preferably, the inside of the cutter head offers the second threaded hole, the second threaded hole opened up inside the cutter head
Internal whorl is set with threaded rod.
Be compared with the prior art, the utility model have it is following the utility model has the advantages that
1, the long-life hard alloy milling-planing teeth can be incited somebody to action by being used cooperatively between link block, cutter head and threaded rod
Link block is fixed on the top of cutter head, while being used cooperatively by link block and point of a knife, when ensure that point of a knife damage, only needs more
Damage point of a knife and link block are changed, manufacturing cost is reduced.
2, the long-life hard alloy milling-planing teeth, passes through being equipped between cutter head, guard circle, knife handle and fixture block, energy
Enough chipping wear knife handles effectively avoided when processing, extend the service life of knife handle.
