[0002] The spindle is an important component in textile machinery and is used to place the yarn tube for yarn feeding. The spindle rod on which the yarn tube is mounted is driven to rotate by the driving belt of the machine. The spindle has a spindle core and a spindle seat. The spindle core includes a spindle sleeve and a spindle rod rotatably arranged in the spindle sleeve. The spindle seat is provided with a spindle core mounting hole. The spindle core needs to be installed in the spindle core mounting hole in a detachable form. This is because the spindle core needs to be taken out for maintenance. The maintenance aspects include replacing bearings and adding spindle oil, etc. The existing spindle core has a detachable structure on the spindle seat. A locking piece is provided on the wall of the spindle core mounting hole of the spindle seat, and the locking piece can be taken out from the outside of the spindle seat. The locking piece is fixed on the spindle seat. When the spindle core is to be removed, the fixing piece must be loosened first, and then the locking piece must be taken out. This process is time-consuming and labor-intensive, resulting in a long downtime. The number of spindles on a loom can be as many as nearly two hundred. If the maintenance time of each spindle is long, the equipment maintenance cost will be significantly increased. Summary of the invention
