Compared with prior art, the beneficial effects of the invention are as follows：
1 presser feet sew work start when pressure and sewing work after the completion of enhancing action driven by stepper motor, therefore,
Pressure and the hoisting depth of presser feet can be automatically controlled according to the program woven.
The impulse stroke of 2 presser feets is controlled by mechanical linkage, and the impulse stroke of presser feet is adjustable, can meet different works
The demand of condition.The stroke of presser feet it is adjusted it is good after, change regardless of the pressure height of presser feet during sewing, the work of presser feet
Remain constant as stroke.
The pressure adjustable that 4 presser feets apply to fabric：The pressure that presser feet applies to fabric is provided by an extension spring, the bullet
The impulse stroke of spring is adjustable, and therefore, user can carry out the pressure demand of presser feet according to different fabrics and different sewed products
Adjustment.
5 presser feets have pressure overload protection function, can be provided pressure more than presser feet when sewing to suddenly encounter in work
Reaction force when, this reaction force can jack up presser feet upwards, will not cause the damage of presser foot drive.
Realize during sewing same part product, can needed for the fabric thickness and material according to different zones, with
When change presser feet pressure height.
