In order to achieve the above object, the utility model provides a Y-shaped needle that processing acupuncture non-woven fabrics was used, include needle handle, needle bar, one section needle body at least, the puncture section that turns right from a left side and set gradually, the tip of puncture section is equipped with the needle point, and the puncture section both sides are equipped with the recess, be equipped with the opening that is linked together with the recess on the needle point, the diameter of the needle bar, the diameter of needle body, the diameter of puncture section reduce in proper order, needle handle and needle bar link to each other perpendicularly, and needle handle and needle bar surface all are equipped with the magnetism and inhale the layer.
Preferably, the number of the needle bodies is 2, the two needle bodies are respectively a first needle body and a second needle body, the left end and the right end of the first needle body are respectively connected with the needle rod and the second needle body, the right end of the second needle body is connected with the puncture section, the diameter of the first needle body is larger than that of the second needle body, so that the length of the fork-shaped needle is increased, and the puncture force of the puncture section during puncture can be reduced by the three-diameter-reducing design.
Preferably, the needle rod and the needle body and the puncture section are connected through a connecting part, and the outer edge of the connecting part is gradually narrowed from left to right, so that the connecting part is relatively smooth, and the puncture force is reduced.
Preferably, the opening is U-shaped to facilitate puncturing and pulling the fibers toward the groove.
Preferably, the longitudinal section of the groove is in the shape of an isosceles trapezoid with one open end, so that the fibers can stably move in the sliding groove.
Preferably, the depth of the recess is no more than 30% of the diameter of the piercing section.
Preferably, the outer edge of the needle rod is provided with a clamping groove, so that the fork-shaped needle can be matched and stably arranged on the needle holder conveniently.
The utility model has the advantages that: the magnetic absorption layers are arranged on the surfaces of the needle bar and the needle handle, so that the fork-shaped needle and the real holder are firmly installed; an opening communicated with the groove is formed in the needle point, and grooves are formed in two sides of the puncture section, so that the fork-shaped needle can pull fibers to form plush and stripes during puncture; the diameters of the needle rod, the needle body and the puncture section are reduced in sequence, so that the puncture force can be effectively reduced.
The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
