Description

technical field [0001] The invention relates to a needle fixing device of a needle selector. Background technique [0002] At present, there are many kinds of needle fixing devices of known needle selectors, such as the ones in which the needle head and the collet are integrated, and the needle head is connected with the collet by a clamping device with a protruding reed. The former cannot replace the damaged needle alone, but needs to replace the entire needle selection to cause unnecessary losses; the latter can replace the damaged needle, that is, pull out the old needle and insert a new needle, but pulling out and inserting When the protruding head reed is easily damaged, the positioning of the clamping device will be affected when the number of replacements is large. Contents of the invention [0003] In order to make up for the above shortcomings, the present invention provides a needle fixing device for a needle selector with accurate positioning and long service l...
