Abstract
The utility model discloses a safe and convenient ligature cutter, which comprises a cutter body and a tool holder. The cutter body is formed by a sharp cutting part which is processed out on a metal round rod, a smooth surface spherical shape end and an extended surface under the cutting part. A thin neck is formed between the cutting part and the end; the included angle of the shaft line of the cutting part and the metal round rod is 30 DEG-45 DEG. When the utility model is used, the end is inserted into the seam to impel the ligature cutter advancing. Because the outer support effect of the extended surface, the cutting part is positioned in the center of the seam all along and cuts the suture one by one.
Description
The utility model relates to a kind of seam ripper.
It is that very time-consuming, common way is to choose line disconnected or with the cut-out of hilt line, this way is not only time-consuming but also trouble, and makees also like this and easily clothes is scratched with awl that sewing machine or the manual line that is sewn on the clothes are removed.
The purpose of this utility model is that a kind of take out stitches convenient and seam ripper fast and safely will be provided.
The seam ripper that the utility model relates to is to be made of cutter hub that sharp blade is arranged and hilt.Cutter hub processes one at an end of a hard metal bar and becomes the blade of about 30 °～45 to form with rod axis, and the front end of cutter hub is ganoid sphere, can prevent that like this cutter hub from scratching clothes.Two sides at blade have abducent two surfaces, and its effect is to make blade aim at the seam center all the time.
Use this seam ripper, no matter big seam or crack can be taken apart at an easy rate, and don't can scratch clothes.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.
Fig. 1 is the side view according to seam ripper of the present utility model.
Fig. 2 is the vertical view of seam ripper.
Fig. 3 is the A-A cutaway view of seam ripper cutter hub.
The schematic diagram that Fig. 4 and Fig. 5 use for the reflection seam ripper.
As illustrated in fig. 1 and 2, seam ripper comprises cutter hub 1 and hilt 2.Hilt 2 can be made the about 10mm of hilt 2 diameters with plastics or timber, metal.Cutter hub 1 is to make with the stainless steel of the about 3mm of diameter, and the about 30mm of length processes blade 4, termination 6, neck 8 and expanding surface 10 at the front end of this round bar.Blade 4 has about 40 ° of inclinations angle with respect to the axis of round bar, shown in dotted line among Fig. 15.Expanding surface 10 is outwards stretched by blade 4, and the angle of two faces is 75 °.Termination 6 is made ganoid spherical, and diameter is about half of round bar diameter.The thinnest part between blade 4 and termination 6 promptly is a neck 8.
When using above-mentioned seam ripper, earlier termination 6 is inserted in the seam, neck 8 is sandwiched in the seam naturally so, promote seam ripper and advance along direction shown in the arrow B this moment, as shown in Figure 4 and Figure 5, the axis of cutter hub 1 and hilt 2 becomes 30 °～45 when advancing with direction of advance, and blade 4 is approximately vertical with direction of advance like this.Along with cutter marches forward, suture 11 is cut off one by one.Because the outer support effect (shown in Figure 5) of expanding surface 10 opposite joints makes blade 4 be positioned at the center of seam all the time.
Claims (3)
1, a kind of seam ripper is made of cutter hub 1 and hilt 2, it is characterized in that cutter hub 1 is that an end is provided with blade 4, the metal round rod of termination 6, neck 8 and expanding surface 10.
2, according to the seam ripper of claim 1, the angle that it is characterized in that the axis of said blade 4 and said metal round rod is 30 °～45 °.
