Handle opens up one end of chamber groove, and makes chamber slot lock tight or loosen.
The purpose of this utility model and solving its technical problem can also take following technical measures further to realize.
Foregoing hand cutting tool, anti-skid bulge is additionally provided with the handle.
Foregoing hand cutting tool, the protection device are mounted on blade.
Foregoing hand cutting tool, the locking device include pipe clamp, bolt, nut.
Foregoing hand cutting tool, the inner ring of umbrella protective case is rectangle, outer ring is circular, and is sheathed on blade.
Foregoing hand cutting tool, the cutter head use quenching technical, and knife tail uses annealing process.
Foregoing hand cutting tool, the angle between the declivous cutting edge and blade of the cutter head are 40 ° to 65 °.
By above-mentioned technical proposal, a kind of Al alloy parts specialized hand cutter of repairing of the present utility model is capable of safety
Suitable for the finishing and cleaning of aluminum alloy materials, the cutter hub and handle of the hand cutting tool are to be detachably connected, when the trickle hair of repairing
Bian Shi, hand-holdable handle such as are pushed away, shoveled, being picked, being ground at a variety of operations；When aluminium alloy castings surface flash is larger, is only grasped with hand
When being difficult to clean up, then handle can be laid down, the effect of flat chisel be played with hand hammer impact knife tail, so as to solve each of aluminium alloy castings
Kind processing finishing problem.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technology of the present utility model
Means, and being practiced according to the content of specification, and to allow above and other purpose of the present utility model, feature and excellent
Point can become apparent, and below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model handle.
Fig. 3 is Fig. 2 schematic side view.
Fig. 4 is the structural representation of the utility model cutter hub.
Embodiment
Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model taken,
Below in conjunction with accompanying drawing and preferred embodiment, to according to the utility model proposes a kind of finishing Al alloy parts specialized hand cutter
Its embodiment, structure, feature and its effect, describe in detail as after.
As shown in Figures 1 to 4, a kind of finishing Al alloy parts specialized hand cutter, including cutter hub 1, handle 2, locking dress
3 and protection device 4 are put, the cutter hub 1 is mounted on the handle 2；The cutter hub 1 includes integrally formed cutter head
11st, blade 12, knife tail 13；The cutter head 11 is section declivous cutting edge triangular in shape, knife tail 13 is cambered surface convex, the blade
12 are provided with the protection device 4, and the protection device 4 includes fastening screw 41 and the positioning retainer ring being sheathed on blade 12
Positioning retainer ring 42 is pressed on blade 12 so as to be carried out to umbrella protective case 43 by the 42nd, umbrella protective case 43, the fastening screw 41
It is spacing；The chamber groove 21 inserted for cutter hub 1 is offered on the handle 2；The locking device 3 opens up chamber groove 21 located at handle 2
One end, and chamber groove 21 is locked or is loosened.
Preferably, it is additionally provided with anti-skid bulge 22 on the handle 2.
Preferably, the protection device 4 is mounted on blade 12.
Preferably, the locking device 3 includes pipe clamp 31, bolt 32, nut 33, bolt and nut be used cooperatively so as to locking or
Loosen pipe clamp 31, cost is cheap, simple in construction.
Preferably, the umbrella protective case 43 is inner ring is rectangular through-hole, outer ring is circular gum cover, and is sheathed on blade 12
On.
Preferably, the cutter head 11 uses quenching technical, hardness is high, beneficial to shoveling aluminum alloy surface flash；Knife tail 13 uses
Annealing process, hardness is low, but has good impact resistance, is impacted repeatedly beneficial to hand hammer.
