[0002] The needle plate of a knitting machine generally has a row of needle grooves separated by a number of bars on one surface of the needle plate body. Embedded grooves are provided at the front and rear ends of a row of needle grooves, and corresponding knitting needles are inserted into the needle grooves. The knitting needles are embedded in the needle grooves through the cooperation of the embedded strips and the embedded grooves, so that the knitting needles can only move forward and backward in the needle grooves but not up and down.

[0003] For example, the Chinese patent with the publication number CN2477664Y discloses a needle plate of a knitting machine, which is composed of a needle plate body 5, mounting holes 4 arranged at both ends of the needle plate body 5, a row of needle slots 1 separated by a plurality of grid bars 2 arranged in the middle of the upper plane of the needle plate body 5, and embedded grooves 7 arranged at the front and rear ends of the row of needle slots 1. A row of needle slots 10 separated by a plurality of grid bars 9 is also symmetrically arranged on the lower plane of the needle plate body 5, and embedded grooves 3 are arranged at corresponding positions at the front and rear ends of the row of needle slots 10.
