Problems solved by technology
[0002] When the thickness of the fabric is different, the locket sewing machine needs to have different tooth heights to adapt to the feeding effect. The sewing machine of the thin material series and the thick material series needs to use different tooth heights. When users encounter different thickness sewing materials in use, sometimes It is necessary to adjust the angle of the fork to obtain different tooth heights, but the adjustment process is not precise, and it is difficult to control when the angle of the fork changes. When the screw of the fork is locked, the manual vibration does not reach the ideal angle. It does not move, and after adjustment, it is prone to the situation that the screw is not locked in place and the tooth fork shifts, which leads to the situation that the height of the feed dog required by the customer cannot be reached.

The invention relates to a tooth frame height adjustment mechanism of a lockstitch sewing machine. When using the tooth frame height adjustment mechanism of a locket sewing machine to adjust the height of the tooth frame, the bolt on the adjustment frame is inserted by rotating the adjustment frame. In different adjustment holes, the first eccentric pin can be rotated so that the second pin rotates in the slider, and the rotation of the second pin can make the first pin lift or drop the feed dog to a certain height. In this way, the height of the tooth frame of the lockstitch machine can be easily adjusted to adapt to different fabric thicknesses. It can be seen that the tooth frame height adjustment mechanism of a lockstitch sewing machine of the present invention can easily adjust the tooth frame height, has a simple structure and is easy to use.
Description
technical field [0001] The invention relates to a height adjusting mechanism of a tooth frame of a lockstitch machine. Background technique [0002] When the lockstitch machine faces different fabric thicknesses, it needs to have different tooth heights to adapt to the feeding effect. The lockstitch machine for sewing thin material series and thick material series needs to use different tooth heights. When users encounter different thicknesses of sewing materials, sometimes It is necessary to adjust the angle of the fork to obtain different heights of teeth, but the adjustment process is not precise, and it is difficult to control when the angle of the fork changes. If it does not move, it is prone to the situation that the screw is not locked in place and the tooth fork is displaced, resulting in the failure to reach the height of the feeding tooth required by the customer. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned shortcomings of the prior art, th...
