Description

Knife handle steel needle holder

The present invention is applied to the technical field of steel needle retainers, in particular to a steel needle retainer for a knife handle. The angle and structure of the steel needle holder change the resistance of the joint when the tool is changed, and the internal components of the knife handle are not easily fatigued. And the fault, which in turn increases the service life.

According to the conventional knife, there are many kinds of steel needle retainers. For example, the conventional steel needle retainer is made of aluminum alloy and has a number of quadrangular perforations. The ends of the steel needle retainer have a tilt angle of 1 degree. The difference is that it is installed in the handle, and the purpose is to media the cutter joint to fix the cutter in the cutter in a rotating manner, or to change the cutter to increase convenience; however, there are still many defects in the conventional steel needle retainer, wherein The blade joint is often inaccessible due to the shavings, dust and moisture applied by the implement, so that the cutter joint is difficult to replace or disassemble the cutter, or the internal joint of the cutter joint is easily fatigued due to the vibration of the application; The steel needle holder has a width of about 0.6 to 0.8 mm between the perforations of the quadrilateral perforations, and is intended to rotate or clamp the components of the cutter for the cutter joint, but the conventional steel needle holder is not easy to rotate, and often After use, the retainer is easily deformed due to fatigue or excessive force, which makes the joint of the knife turn hard and even malfunctions, which not only causes an increase in maintenance cost but also reduces the life. The efficiency even lose the original specifications set goals, let the product yield drops.

Therefore, how to open the problem of the above-mentioned conventional steel needle holder It is a eager anticipation for consumers to develop an innovative structure that is more ideal and practical. It is also the goal and direction of relevant industry players to work hard to develop breakthroughs.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the author has finally achieved a practical and practical creation.

The present invention provides a steel needle holder for a knife handle, comprising: a knife handle, a sheath, a steel needle holder, a C-ring, a cutter head and a stop ring; wherein the knife handle protrudes from the outer ring and The other free end is provided with a collet, and the free end of the collet is inserted into the sheath to prevent the entry of small foreign matter; the sheath has the effects of waterproof, dustproof and shockproof.

a cutter head, the surface of the cutter head is provided with a plurality of groove holes; the steel needle retainer is provided with a plurality of perforations, and each of the quadrangular perforations is arranged with four steel needles, and is inserted into the cutter head, and then the C-shaped buckle is arranged Provided on the cutting head for positioning the steel needle holder; each of the rectangular needles perforating a short side of the steel needle holder is inclined at an angle of 1 degree in the same direction, so that the four-sided perforations are arranged to form the steel needle having a thread principle. And the ribs between the quadrilateral perforations having a width of 1.2 mm are made of special alloy steel, wherein the short sides of each of the quadrilateral perforations are equivalent to the width of the short side of the ribs; in addition, the threading principle The steel needle retainer saves effort when fixing or dismounting and the ribs are made of special alloy steel and have a width of 1.2mm for durability.

Rotating the cutter head into the collet, and inserting the stop ring at the other free end of the cutter head, the stop ring is provided with an O-ring on the outer ring to have a sealing effect, and is arranged in the stop ring The six perforations are equally spaced, and the perforations are respectively arranged with the locking holes and the cooling liquid holes, and finally the three fixing screws are locked on the stop ring.

With regard to the techniques, means and functions of the present invention, a preferred embodiment is described in detail with reference to the drawings, and it is believed that the above objects, structures and features of the present invention can be obtained from an in-depth and specific understanding. .

Referring to Figures 1 to 7, the present invention provides a steel needle holder for a knife handle, comprising: a knife handle 11, a sheath 12, a steel needle holder 21, a C-ring 23 and a stop ring 33. Wherein the center of the blade 11 is provided with an axial through hole and the outer circumference of the blade is tapered toward a free end, and the outer ring 13 is protruded from the other free end of the blade and a collet 14 is provided, and the collet 14 is further set. The sheath 12 is inserted to prevent the entry of small foreign matter; the sheath 12 has the effects of waterproofing, dustproof and shockproof; a cutter head 31 having a plurality of recessed holes 32 in the surface thereof; the steel needle retainer 21 has an inclined opening at both ends thereof The angle is 1 degree and is provided with a plurality of quadrangular perforations 24, and each of the quadrilateral perforations 24 is arranged with four steel needles 22, and is placed in the cutter head 31, and the C-shaped ring 23 is buckled on the cutter head 31 for positioning. The steel needle holder 21; each of the quadrangular perforations 24 of the steel needle holder 21 is radially in the same direction Tilting at an angle of 1 degree, the quadrilateral perforations 24 are arranged to form the steel needle holder 21 having a thread principle, and the ribs 25 between the quadrilateral perforations 24 are 1.2 mm wide and are made of special alloy steel, wherein the ribs are each The width of the short side width a of the column is equal to the width b of each of the quadrangular perforations, that is, the length of 2a=b; in addition, the steel needle holder 21 having the thread principle can save labor and ribs when fixing or disassembling 25 because of the special alloy steel and the width of 1.2mm to improve the durability; the cutter head 31 is inserted into the collet 14 in a rotating manner, and the stop ring 33 is placed at the other free end of the cutter head 31, An O-ring 35 is provided on the outer ring of the retaining ring 33 to have a sealing effect, and the retaining ring 33 is provided with equidistant six perforations, and the perforations are respectively arranged with the locking holes 37 and the cooling liquid holes 36 interposed, and finally the stop Three fixing screws 34 are locked to the ring 33.
