Description
[technical field]
The utility model relates to a kind of tapping knives.
[background technique]
In the prior art, the general length of tapping knife is 30cm, wooden knife handle, for scratching gum bark.Common sword
The section in portion is " V " shape, is cut by blade.However, influence of this blade to cutting edge cut sharpness require it is very high, because
Very high for gum bark fiber toughness, this cutting edge is prone to wear, after cutting edge abrasion, because traditional tapping knife is non-dismountable more
It changes, and again thicker, sharpening is difficult, therefore very lost labor.
[utility model content]
The technical problem to be solved by the present invention is to provide a kind of tapping knives that service efficiency can be improved.
Purpose of the utility model is realized as follows:
A kind of tapping knife, including knife handle and cutter hub, the knife handle is in hollow form structure, between the knife handle and the cutter hub
Equipped with attachment base, the lower part of the attachment base is sheathed on the end of the knife handle, and the lower part of the cutter hub is plugged in the connection
The top of seat is equipped with the fixing piece for compressing the cutter hub, institute between the lower part of the cutter hub and the top of the attachment base
State the connector that the other end of knife handle is detachably connected equipped with the hollow portion across the knife handle with the fixing piece.
A kind of tapping knife as described above, the connector and the fixing piece are connected through a screw thread fixation.
The top of a kind of tapping knife as described above, the attachment base is equipped with arc groove, correspondingly, under the cutter hub
Portion is equipped with the arc interconnecting piece that cooperation is plugged with the arc groove.
A kind of tapping knife as described above, the cross section of the cutter hub are in V-shape.
The utility model compared with prior art, has following technical characterstic:
1, the lower part of cutter hub is plugged in the top of attachment base, and makes knife by fixing piece and being detachably connected for connector
Body is fixed on attachment base, after cutter hub abrasion, can directly be replaced the cutter hub of abrasion, without by other components such as handles
It is replaced, to increase the service efficiency of the other components such as handle, avoids wasting；
2, connector and fixing piece are connected through a screw thread fixation, so that the angle of cutter hub is adjusted during rubber tapping, side
Just it operates；
3, the top of attachment base and the lower part of cutter hub are respectively equipped with the arc groove for being mutually inserted cooperation and arc interconnecting piece,
So that cutter hub replacement grafting is more convenient；
4, the cross section of cutter hub is in V-shape, and cutter hub is with a thickness of 0.8 millimeter so that the edge of a knife is sharp, use it is relatively labor-saving,
And it is not easy to skid when cutting.
[Detailed description of the invention]
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is the decomposition texture schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of the utility model；
Fig. 3 is the portion the I enlarged drawing in Fig. 2.
[specific embodiment]
A kind of tapping knife as shown in Figure 1, is in the cutter hub 2 of V-shape including knife handle 1 and cross section, and knife handle 1 is in hollow form knot
Structure is equipped with attachment base 3 between knife handle 1 and cutter hub 2, the lower part of attachment base 3 is sheathed on the end of knife handle 1, the lower part grafting of cutter hub 2
The fixing piece 4 for compressing cutter hub 2, knife handle are equipped in the top of attachment base 3, between the lower part of cutter hub 2 and the top of attachment base 3
1 the other end is equipped with the hollow portion across knife handle 1 and is connected through a screw thread fixed connector 5 with fixing piece 4.
The top of attachment base 3 is equipped with arc groove 31, and correspondingly, the lower part of cutter hub 2 is equipped with and 31 phase of arc groove
Mating arc interconnecting piece 21.
When the utility model needs replacing cutter hub 2, then need to only turn connector 5 is detached from it with fixing piece 4, can will damage
Bad cutter hub 2 is replaced, the arc groove being directly plugged on attachment base 3 with the arc interconnecting piece 21 of cutter hub 2 that will be new
31, then fixing piece 4 is compressed it and is threadedly coupled fixation with connector 5 again, that is, completes replacement.
