Connecting rod is rotated around the fixing axle, and the connecting rod connects the cushion block；Axis pin, the axis pin are provided on the presser feet installing handle
Both ends connect swivel link, elongate slots are provided on the swivel link, the swivel link upper end connects the first tension spring, described
Swivel link lower end connects cushion block；Axis pin is provided on the presser feet installing handle, the axis pin both ends connect swivel link, described
Elongate slots are provided on swivel link, the swivel link upper end connects compression spring, and the connecting rod lower end connects cushion block；The rotation
Turn to be provided with the second tension spring in the middle part of connecting rod.
Using the above scheme, due to being provided with overturning cushion block on presser feet bottom plate, cushion block is in pressure to the utility model when normal
Above sole or rear, cushion block is located at presser feet bottom base plate when overturning, the beginning in the thicker fabric of sewing or turning
When, cushion block overturning is located at pressing sole board bottom portion, passes through the control of pad thickness so that in the beginning for sewing thicker fabric or turns
When crook, presser feet is front and back in a plane, ensures that presser feet uniformly pushes down fabric, when feed dog works so that fabric motion homogeneous,
It avoids feed dog from frequently being dragged in the same position of fabric, prevents from galling fabric, to ensure that the sewing quality of clothing.
