Description

The knife sharpener of use in sewing machine rag knife

Technical field

The utility model is for providing a kind of knife sharpener of use in sewing machine rag knife, and espespecially one can be ground for rag knife, makes its recovery sharp, changes the cost of charp tool to save to eliminate, and the knife sharpener of the use in sewing machine rag knife of process of lapping safety and firmness.

Background technology

In use for some time, its sharpness must wear and tear any cutter to some extent, and in order to continue to use this cutter, grinding is necessary means.But in commercially available grinding facility, though traditional hand-ground plate, grinding rod can be dealt with all cutters, but manual operation is difficult at every turn exhaustive, and easily causes user's msuscle soreness or accidentally injured, and automatic grinder, conventionally be applicable to large-scale cutter, for example: kitchen knife, fruit knife etc., and its structural design, nothing more than one can allow cutter hub insert narrow slit or the cutter groove of particular design, even have two-sided simultaneous grinding.This kind of design, very convenient to the grinding of large-scale cutter, but for the cutter of small volume or there is no the cutter of handle, be not suitable for above-mentioned two kinds of facility.

Compared to large-scale cutter, although the cutter wearing and tearing probability that volume is little is not higher, but after long-term use or under improper use, its degree of passivation also not fear allow more, especially the rag knife of Sewing machines, the external form that its cutter is special, increases the difficulty of grinding gimmick, conventionally user can select the cutter directly more renewing, and saves the trouble that process of lapping causes.

Right above-mentioned grinding facility are in the time using, for really existing following point and disappearance to wait to improve:

One, there is no to coordinate the type of small-sized cutter.

Two, the external form of rag knife is special, and process of lapping is not more smoothly.

Three, user even abandons grinding, the cutter that more renews of directly spending.

Therefore will how to solve above-mentioned existing problem and disappearance, be applicant of the present utility model and desire most ardently to the relevant manufacturer that is engaged in the industry the direction place that research improves.

Therefore, the applicant is because above-mentioned disappearance, be to collect related data, via in many ways assessing and considering, and to engage in the many years of experience of the industry accumulation, via constantly studying and revising, begin to design this kind and be in particular rag knife design, can easily complete the grinding of rag knife, further save the utility model patent of the knife sharpener of the use in sewing machine rag knife of the cost of replacing new cutter.

Utility model content

Technical problem underlying to be solved in the utility model is, overcome the above-mentioned defect that prior art exists, and provide a kind of knife sharpener of use in sewing machine rag knife, it is the knife sharpener of a grinding rag knife, and only rag knife need be placed on and put on cutter platform, base portion and operating assembly are fixed, and manually adjust rag knife to suitable position and angle, fixed with fixture, further adjust position and angle with operating assembly again, then can carry out automatic grinding, and save the troublesome steps of grinding, more can save cost.

The utility model solves the technical scheme that its technical problem adopts:

A kind of knife sharpener of use in sewing machine rag knife, comprise: one for the knife sharpener that grinds rag knife, and be provided with an operating assembly in this knife sharpener one side place, and this operating assembly is provided with one for setting firmly the fixing tool rest of this rag knife, and this fixing tool rest includes one and is extended to form for placing putting cutter platform and being at least onely fixedly arranged on this and putting on cutter platform and for the fixture that sets firmly this rag knife of this rag knife by this base portion with the base portion of the mutual clip of this operating assembly; In the time of user's Sewing machines rag knife passivation, can use the knife sharpener of the utility model for rag knife design, now first this rag knife is placed on and is put on cutter platform, and to put fixture on cutter platform by firm rag knife pressing, again base portion is fixed on operating assembly firmly to put cutter platform, finally with operating assembly, fixing tool rest is done to the adjustment of carrying out position and angle, can easily complete the grinding of rag knife, and without eliminating the cutter renewing or the grinding of wasting time and energy, even spend to give to repair.

The knife sharpener of aforesaid use in sewing machine rag knife, wherein knife sharpener has a motor.

The knife sharpener of aforesaid use in sewing machine rag knife, the emery wheel that wherein motor and is located at this knife sharpener one side place links mutually.

The knife sharpener of aforesaid use in sewing machine rag knife, wherein operating assembly comprises one for keeper, an operating handle for this fixing tool rest of adjustment and an operation knob for this fixing tool rest of fine setting that this base portion is set.

The knife sharpener of aforesaid use in sewing machine rag knife, wherein fixture comprises one first fixture and deviates from the second fixture of this first fixture.

By above-mentioned technology, can be broken through for the existing following problems point of existing grinding facility, further reach the practical improvement of above-mentioned advantage: without the machine that is applicable to grinding rag knife, even if use reluctantly, also can be because of the special shape of rag knife itself, promote and make to grind means difficulty, force to such an extent that user ignores cost consumption and selects the rag knife more renewing.

The beneficial effects of the utility model are, it is the knife sharpener of a grinding rag knife, and only rag knife need be placed on and put on cutter platform, base portion and operating assembly are fixed, and manually adjust rag knife to suitable position and angle, fixed with fixture, further adjust position and angle with operating assembly again, then can carry out automatic grinding, and save the troublesome steps of grinding, more can save cost.
