Abstract
The utility model relates to a kind of cutter of penknife, comprise the tool rest with the handle synchronous axial system of penknife, tool rest offers penholder guiding taper hole, described tool rest is at least provided with a blade holder, blade holder is at least provided with a blade, the lead conical surface of taper hole of blade and the penholder of described blade is parallel and embed penholder and lead in taper hole, the blade of described blade and the penholder axis of pencil not perpendicular.The number of parts that the utility model uses is less, add reliability of structure, and adopt the mode of blade chip, development cost is reduced, do not affect its chip efficiency simultaneously, and blade can be one-body molded according to actual needs with blade holder also can be coordinate by assembling, it is convenient to change, and structure is simple.
Description
Technical field
The utility model relates to a kind of cutter of penknife.
Background technology
The cutter of traditional penknife is generally made up of hobboing cutter, hob head, hobboing cutter steady pin, hobboing cutter driven wheel etc., the cutter of this structure suffers to damage once hobboing cutter just must change hobboing cutter, and the cost of hobboing cutter is relatively high, so the cost of this type of cutter is general all higher, and because number of parts is many, so reliability of structure comparatively speaking can be poor.
Utility model content
Technical problem to be solved in the utility model is: provide that a kind of cost is low, number of parts is few and the cutter of the penknife that structural reliability is high.
For solving the problem, the technical solution adopted in the utility model is: a kind of cutter of penknife, comprise the tool rest with the handle synchronous axial system of penknife, tool rest offers penholder guiding taper hole, described tool rest is at least provided with a blade holder, blade holder is at least provided with a blade, the lead conical surface of taper hole of blade and the penholder of described blade is parallel and embed penholder and lead in taper hole, the blade of described blade and the penholder axis of pencil not perpendicular.
Preferably, described tool rest can be arranged two relative blade holder.
Preferably, described tool rest and handle are by being threaded.
Preferably, described blade and blade holder can be formed in one and design.
Preferably, described blade coordinates by assembling with blade holder.
The beneficial effects of the utility model are: the number of parts that the utility model uses is less, add reliability of structure, and adopt the mode of blade chip, development cost is reduced, do not affect its chip efficiency simultaneously, and blade can be one-body molded according to actual needs with blade holder also can be coordinate by assembling, it is convenient to change, and structure is simple.

Fig. 4 is the plan structure figure of Fig. 2;
In figure: 1, tool rest, 11, penholder guiding taper hole, 12, screw thread, 2, handle, 3, blade holder, 4, blade, 5, pencil.
Detailed description of the invention
The utility model is further described by specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the cutter of described a kind of penknife, comprise the tool rest 1 with handle 2 synchronous axial system of penknife, tool rest 1 offers penholder guiding taper hole 11, described tool rest 1 is at least provided with a blade holder 3, blade holder 3 is at least provided with a blade 4, the lead conical surface of taper hole 11 of blade and the penholder of described blade 4 is parallel and embed penholder and lead in taper hole 11, the blade of described blade 4 and the penholder axis of pencil 5 not perpendicular.
The utility model does not do concrete restriction to the number of tool rest 1 upper blade holder 3 and the number of blade 4, when preferentially selecting, tool rest 1 described in the utility model is provided with two relative blade holder 3, and blade holder 3 is provided with 5-6 blade 4, as shown in Figure 3, Figure 4, so not only can not increase too many cost but also chip efficiency can be made to be improved;
Tool rest 1 described in the utility model is connected by screw thread 12 with handle 2, thus realizes synchronous axial system; Blade described in the utility model 4 and blade holder 3 can be formed in one and design, when needs more allowing blade replacement 4 time needs blade holder 3 is together changed, safer comparatively speaking; Described blade 4 and blade holder 3 also coordinate by assembling, when needs more allowing blade replacement 4 time only need in blade holder 3 directly more allowing blade replacement 4 just can, cost is lower.
During concrete use, only need the utility model be arranged in penknife, by being connected with handle 2, as shown in Figure 2, pencil 5 is inserted in penholder guiding taper hole 11, when handle 2 turns clockwise, the utility model also does clockwise rotation under the effect of handle 2, and blade 4 now can carry out chip to pencil 5, when the conical surface of tool rest 1 inner penholder guiding taper hole 11 encountered by pencil 5, tool rest 1 prevents moving on of pencil 5, until blade 4 pairs of pencils 5 complete chip.
The number of parts that the utility model uses is less, add reliability of structure, and adopt the mode of blade 4 chip, development cost is reduced, do not affect its chip efficiency simultaneously, and blade 4 can be one-body molded according to actual needs with blade holder 3 also can be coordinate by assembling, it is convenient to change, and structure is simple.
