Movable post, cutterhead end face is provided with some fixing posts circumferentially distributed along cutterhead, and fixing post is arranged near installing hole, also includes some
Extension spring, extension spring two ends are respectively provided with the hook being hooked on movable post and fixing post, and some extension springs are radially arranged along cutterhead, and can lead to
Crossing centrifugal motion makes point of a knife and blade stretch out in cutter groove, and makes blade front edge be against on locating piece, now fixes bar patch
It is combined on the blade top surface that adjacent two line of weakness are corresponding.
Owing to extension spring two ends hold fixing post and movable post respectively, therefore during mounting or dismounting cutterhead, point of a knife and blade begin
Final position, in cutter groove, is avoided that point of a knife highlights initiation potential, during use, is arranged on motor shaft by installing hole, passes through motor shaft
Band movable knife disc rotates, and makes blade stretch out in cutter groove by centrifugal motion, therefore only uses and blade just can be made to highlight, therefore
Use safer, utilize locating piece to play positioning action, it is ensured that each blade extension is identical simultaneously, when blade damages
After, push out blade, utilize fixing bar as support, break disconnected portion blade up along line of weakness, can use new afterwards
Blade, therefore can improve cutting-tool's used life.
As preferably, described movable post is hollow-core construction, the screwed hole that movable post and blade are communicated with, and can lead to
Cross bolt to coordinate with screwed hole and be spirally connected, and make bolt hold out against cutter groove bottom land, make blade be fixed on cutter groove.
Therefore can conveniently fix blade to use.
As preferably, cutter groove both sides cell wall near blade rear end position in deepening to arrange, and blade both sides and cutter groove both sides
Cell wall is slidably matched.
As preferably, cutterhead is provided with some lightening holes being radially and circumferentially distributed along cutterhead.
Compared with prior art, this utility model has the advantage that
Owing to extension spring two ends hold fixing post and movable post respectively, therefore during mounting or dismounting cutterhead, point of a knife and blade begin
Final position, in cutter groove, is avoided that point of a knife highlights initiation potential, during use, is arranged on motor shaft by installing hole, passes through motor shaft
Band movable knife disc rotates, and makes blade stretch out in cutter groove by centrifugal motion, therefore only uses and blade just can be made to highlight, therefore
Use safer, utilize locating piece to play positioning action, it is ensured that each blade extension is identical simultaneously, when blade damages
After, push out blade, utilize fixing bar as support, break disconnected portion blade up along line of weakness, can use new afterwards
Blade, therefore can improve cutting-tool's used life.
