Specific embodiment
As shown in Fig. 1 ~ 10, a kind of grooving cutter, including knife bar 1 and the cutter hub 2 positioned at the front end of knife bar 1, it is removable in cutter hub 2
Unload and blade 3 is installed, the cutter hub 2 includes the regulation section 201 extended forward successively from the front end of knife bar 1 and gripping section.The tune
The lower surface of sections 201 and the flush of knife bar 1, adjust the upper surface of the upper surface higher than knife bar 1 of section 201, and the upper surface of knife bar 1
It is connected using inclined-plane between the upper surface of the regulation section 201 of cutter hub 2；Middle and upper part is provided with left and right in the horizontal direction in regulation section 201
Through through hole 206, the longitudinal center line of the through hole 206 is slightly above the upper surface of knife bar 1, and the front side of through hole 206 is along level side
To being provided with the groove 205 that runs through of left and right, the front end of the groove 205 extends to the front end of regulation section 201, the rear end of groove 205 with
Through hole 206 is connected and the diameter for being smaller than through hole 206 between the upper and lower surface of groove 205；It is provided with regulation section 201
The screw 4 of groove 205 is passed perpendicularly through, the part that the regulation section 201 is located at the top of groove 205 is provided with for the countersunk head of screw 4 peace
The shoulder hole of dress, the part that regulation section 201 is located at the lower section of groove 205 is provided with the screwed hole installed for the fastening of screw 4.The folder
Hold section be located at regulation section 201 front left side, gripping section include upper clamping part 204 opposing upper and lower and lower clamping part 202, it is described under
The upper surface of clamping part 202 is stepped, the upper surface at the lower rear portion of clamping part 202 and the lower surface flush of groove 205, lower folder
Hold at the ladder in portion 202 using the lower inclined plane 2022 before being tilted towards, the spacing shape between upper clamping part 204 and lower clamping part 202
Into insert groove 203, the rear side of insert groove 203 is connected with groove 205；The lower surface of the upper clamping part 204 is along the longitudinal direction
The first projection 2041 of V-arrangement is provided with, the upper surface of lower clamping part 202 is provided with the first groove 2021 of V-arrangement along the longitudinal direction.It is described
Blade 3 is located in insert groove 203, and the gripping section of cutter hub 2, the rear end of blade 3 and lower clamping part 202 are stretched out in the front end of blade 3
