[0002] The existing needle selection devices on textile machinery can be divided into electromagnetic needle selectors and piezoelectric ceramic needle selectors according to their working principles. Electromagnetic needle selectors are increasingly widely used due to their simple structure and convenient use. The working principle of electromagnetic needle selectors is as follows: by passing currents in different directions through the electromagnetic spiral tube (i.e., coil), the polarity of the head end of the pin coil changes accordingly, and the attraction and repulsion between the blade permanent magnet are generated to realize the swing of the needle selection head. The assembly structure of the existing needle selectors in the manufacturing process is relatively cumbersome and cannot be directly assembled and formed by automated devices. The internal structure of some needle selectors is not firm, and after long-term use, the internal structure is easy to loosen, thus affecting user use. Utility Model Content
