The working principle of the invention is as follows:

the synchronous shaft is driven to rotate by the rotation of the motor, and the cloth feeding mechanism and the thread hooking mechanism connected to the synchronous shaft work simultaneously.

A cloth feeding mechanism: the second synchronous belt rotates to drive the bearing, the conveying shaft connected to the bearing rotates, and meanwhile, the sliding groove disc, the eccentric wheel sliding block and the eccentric wheel connected to the conveying shaft are driven to rotate, so that the rocker arm is driven to do reciprocating work in the front-back direction and the up-down direction, and at the moment, the presser foot connected to the front section of the rocker arm stably sends cloth into the presser foot through the pressing tooth point.

Front and back thread hooking devices: the rotation of synchronizing shaft drives the rotation of colluding the line eccentric wheel simultaneously, and the even arm of connection on colluding the line eccentric wheel does the fore-and-aft swing simultaneously to drive the line body seat that colludes of even arm anterior segment, owing to collude line body seat activity and set up on the mount pad, so collude line body seat fore-and-aft swing and just driven the fore-and-aft swing of colluding the line body, realize colluding the line around realizing.

Left and right thread hooking devices: the rotation of synchronizing shaft drives eccentric bearing simultaneously and rotates, and the connecting piece does the swing from top to bottom back and forth on the eccentric shaft to drive the connecting axle of connecting the connecting piece below through the skewed center wheel and do the rotation, because connecting epaxial anterior segment and being connected with send the line to collude the seat and send the line to collude, even the rotation of axle will drive to send the line to collude and do the horizontal hunting this moment, realize controlling and send the line.

The motor rotates and simultaneously drives the second gear and the first gear to rotate, and simultaneously drives the lower main shaft to rotate, and the wire feeding mechanism and the pine needle mechanism connected to the lower main shaft also synchronously work, so that all the mechanisms can synchronously work by one power source of one device.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
