In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a fly cutter disc structure with adjustable, includes the blade holder, one side of blade holder is equipped with the bulge loop, three slot has been seted up to bulge loop edge equidistance, the annular has been seted up to the opposite side of blade holder, it has the butt joint groove all to run through between slot cell wall and the annular, it has the counter sink to run through between one side cell wall of butt joint groove and the blade holder outer wall, the counter hole has been seted up on the one side cell wall that the counter sink was kept away from to the butt joint groove, it has the jack all to run through between counter hole and the annular, the fixed flange ring that inlays in middle part of blade holder, a plurality of connecting holes have been seted up to flange ring edge equidistance, three fastening hole has.

Preferably, the counter bore is arranged opposite to the alignment hole.

Preferably, the cross section of the slot is in a T-shaped structure.

Preferably, the connection hole extends completely through the flange ring.

Preferably, the insertion hole and the alignment hole are arranged perpendicular to each other.

Compared with the prior art, the invention has the beneficial effects that: the adjustable fly cutter head structure has the characteristics of reasonable structural design and high strength, when the adjustable fly cutter head structure is used, the cutter seat is not provided with the screw hole structure, the fastening hole on the cutter seat is arranged in an alignment mode with the reserved screw hole on the cutter bar, so that cutting stress is concentrated in the reserved screw hole, the cutter seat structure can be prevented from being damaged, the extending length of a cutter head can be adjusted, the cutter seat is additionally provided with the flange ring and the butt joint groove, stress is more uniform on the stress-concentrated convex claw, the connecting strength with the clamping jaw is high, the jack is vertically arranged with the alignment hole, the bolt can be prevented from loosening after being inserted and connected, and the connecting effect is further ensured.
