The flat sewing machine is a sewing machine commonly used for clothes, bags, leather and the like, and is mainly used for sewing materials together.
When the sewing machine is used for sewing, the moving distance of the lower feeding tooth, particularly the moving distance of the upper and lower synchronous feeding of the upper feeding presser foot determines the sewing needle pitch, namely the distance between two sewing needle holes. The moving distance of the lower feeding and the up-and-down synchronous feeding with the upper feeding presser foot is realized by the needle pitch screw rod connected with the needle pitch knob and linked by some mechanical mechanisms (except for motor transmission). Due to the vibration during sewing, the minute change of the pitch screw is easy to cause for a long time, so that the pitch is changed.
As can be seen from fig. 1: in the flat sewing machine in the prior art, a needle pitch knob locking mechanism is generally used. The needle pitch adjusting screw rod 2 is screwed on the machine body 1, and the needle pitch knob 8 is fixed with the needle pitch adjusting screw rod 2 through a gasket 9 and a screw 10. The stitch length knob 8 is rotated to change the distance of the stitch length adjusting screw 2 entering and exiting the machine body 1 along the screw, so as to adjust the change of the sewing stitch length. The stop pin spring 5 enables the stop pin 6 and the stop plate 7 to abut against the rotary needle distance knob 8 through the stop plate spring 4, the end face of the rotary needle distance knob 8 is provided with a tooth socket, and the front end of the stop pin 6 is inserted into the tooth socket to lock the rotary needle distance knob 8. After the stop plate 7 is pressed down, the stop plate 7 drives the stop pin 6 to move, so that the front end of the stop pin 6 is separated from the tooth groove to be adjusted. When the rotation angle is large, the adjustment is not easy to operate by one hand; the other hand is required to depress the stop plate 7 for adjustment.
