The auxiliary picking and transferring needle is a single auxiliary picking and transferring needle or a double-needle auxiliary picking and transferring needle formed by splicing two auxiliary picking and transferring needles or a three-needle auxiliary picking and transferring needle formed by splicing three picking and transferring needles.

The length of a needle bar on one pair of picking and transferring needles is longer than that of a needle bar on the other pair of picking and transferring needles, or the puncture position of a needle point on one pair of picking and transferring needles is far away from the puncture position of a needle point on the other pair of picking and transferring needles, or two needle points of the two pair of picking and transferring needles are positioned at the same horizontal position.

The lengths of three needle bars of the three-needle pair picking and transferring needle are sequentially increased, or the puncture positions of needle points on the three pair picking and transferring needles are sequentially changed to be far, or two puncture positions are the same, and one puncture position is different, or the three needle points are positioned at the same horizontal position.

The needle rod of the single secondary picking and transferring needle extends outwards to form two needle points or three needle points.

The two auxiliary picking and transferring needles are provided with the same or opposite horizontal bends respectively, and the horizontal bends are connected with needle points; the puncture position of the needle point on the auxiliary picking and transferring needle is far away from the puncture position of the needle point on the other auxiliary picking and transferring needle. The reverse or same-direction horizontal bending structure is equivalent to the performance of clamping and grabbing two coil holes by two needle points to achieve mutual locking.

The needle tip of the picking transfer needle is provided with an inward bayonet. The needle tip of the picking transfer needle is provided with an outward bayonet. The bayonet structure can actively hook the coil to further improve the pick-up performance of the pick-up transfer needle.

The needle point of the picking transfer needle is provided with an inward needle hook. The needle point of the picking transfer needle is provided with a needle hook with a needle latch outwards. The hook structure can actively hook the coil to further improve the picking performance of the picking transfer needle, and the hook with the latch further prevents the coil from being separated accidentally.

The use method of the non-needle-alignment type picking and transferring needle comprises a stitch, a needle rod and a needle point, wherein the needle rod and the needle point are positioned on the same axis or a horizontal axis, and the needle point is bent relative to the needle rod, preferably bent downwards and outwards or bent upwards; the needle point is not provided with a needle groove which is in contact with the knitting needle, the needle point of the transfer needle is picked up to puncture the coil on the fabric when the transfer fabric is picked up, and the needle point and the knitting needle are not matched with each other to directly puncture the coil on the sock or the fabric. According to the using method, the socks or the fabrics are directly punctured to realize the picking and transferring functions of the socks or the fabrics with different needle numbers in the states of the needle cylinders with different needle numbers, and the socks or the fabrics are directly punctured to be picked, so that the picking and transferring needles and the transferring needle discs in the picking device do not need to be matched and replaced, the manufacturing cost of matched parts of equipment is greatly reduced, the picking and transferring efficiency is improved, and the phenomena of needle missing and stitch dropping in the traditional needle picking mode are avoided.

The fabric is a sock, and the pick-up transfer needles are arranged on the hosiery machine, and the number of the needle points of the pick-up transfer needles is 1.1-3 times of the number of the coil holes on one circle of knitted coils of the sock. Because the number of the pick-up transfer needle points is larger than the number of the knitting needles arranged on the needle cylinder, the locking effect on the coils on the socks is caused under the condition of multiple times of the number, and the yarn falling and the needle missing can not occur when the socks knitted by different needle cylinder numbers are picked up and transferred.

The pick-up transfer needle is provided with two needle points, and the two needle points respectively puncture a coil to form a double-needle lockhole effect. The number of the needle points of the pickup transfer needle is three, and the three needle points respectively puncture a coil to form a three-needle lockhole effect.

The two picking and transferring needles respectively puncture a coil, and the two picking and transferring needles reversely move after puncturing to form a lockhole effect, and the locking force is adjustable, so that the picking performance is better.

The picking and transferring needles form a group of two, one needle point downwards and the two picking and transferring needles with the needle point upwards jointly puncture the fabric, and the two picking and transferring needles are locked up and down to achieve the technical performance of picking up the socks or the fabric.

The fabric is socks, when the pick-up transfer needles arranged on the hosiery machine and the tips of the pick-up transfer needles arranged on the hosiery machine puncture the third last circle of the socks or any circle of coils before the third last circle of the socks, the number of the tips of the pick-up transfer needles is less than that of the coil holes on one circle of coils of the hosiery. Because the last loops after the third last loop have the superposition entanglement effect, the last loops of the yarn cannot miss the yarn or leak the stitch, the numerical value of the needle point of the transfer needle picked up when the transfer sock or fabric is picked up can be smaller than or equal to the numerical value of the knitting needle on the needle cylinder, and the yarn cannot miss the stitch when the sock or fabric knitted by different needle cylinder numbers is picked up and transferred;

the non-needle-aligning type picking and transferring needle comprises a picking and transferring needle disc, wherein the picking and transferring needle disc is tubular, and needle points are uniformly arranged on a tube body. The needle point punctures socks or fabrics without aligning with knitting needles on different needle cylinders, so that the socks or fabrics knitted by different needle cylinder needle numbers can not be missed, and the problems of missed stitches, hanging loops and missed stitches in the process of picking and transferring the fabrics are avoided.

The non-needle-aligning type picking and transferring needle comprises a picking and transferring needle with a needle hook and a combined needle formed by the picking and transferring needle with a needle point. The combined needle point punctures socks or fabrics, the needle hook hooks the socks or fabrics, needle alignment with knitting needles on different needle cylinders is not needed, thread and needle missing can not happen when the socks or fabrics knitted by different needle cylinder needle numbers are picked and transferred, and the problems of needle missing, needle hanging and needle missing in the process of picking and transferring fabrics are avoided.
