Freely rotate；Presser feet connecting plate 17 is connected to lift by attachment screw 18 and buckles on handle 12, and freely can rotate；Presser foot lifter draws
Bar 19 is connected to lift by stop screw 20 and attachment screw 18 and buckles on handle 12 and lift pressure spanner 16；Presser feet electric magnet 2
It is fixed in casing 14.
Further, the slide bar 13 includes sliding part 21 and installation portion 22, and the installation portion 22 of slide bar 13 is installed in machine
On shell 14 or guide block 15, the lower end of back-moving spring 11 can be when sewing machine be normally sewed or during presser foot lifter along slide bar
13 sliding part 21 slides.
The specific implementation step of the present invention is as follows：
During normal sewing, in shown in Fig. 7, now back-moving spring 11 provides reset force to back-moving spring 11；Presser foot lifter process
Middle back-moving spring 11 can slide to right-hand member by the sliding part 21 of slide bar 13, as shown in figure 8, the now offer of back-moving spring 11 is exactly
Retentivity, therefore, the presser feet electric magnet 2 of automatic needle-foot-lifting device 1 can provide less power.Because reset force is converted finally
Into retentivity, so the retentivity provided by presser feet electric magnet 2 just can reduce, and then reduce caloric value, reduce temperature, protect
Card presser feet electric magnet 2 normally completes the action of presser foot lifter.
More specifically, the outer end of the sliding part 21 of the slide bar 13 is provided with the other end that hook portion 23 limits back-moving spring 11
The extreme position slided on sliding part 21, can prevent limit spring 11 from separating with the sliding part 21 of slide bar 13.
Further, since one end of the presser foot lifter pull bar 19 of the automatic needle-foot-lifting device 1 is connected to by stop screw 20
The upper end of handle 12 of buckling is lifted, therefore, is connected for convenience, the upper end of the back-moving spring 11 of the present invention is hung on stop screw 20
On, without the need in addition arranging attachment means.
The installation portion 22 of slide bar of the present invention 13 takes the shape of the letter U, and guide block 15 is fixed in casing 14 by screw 24, the peace
Dress portion 22 is connected on screw 24.The screw 24 of the present embodiment is provided with two, and be setting up and down, correspondingly, slide bar 13
Installation portion 22 is set in outside the screw rod of two screws 24, and bottom is connected on the screw rod of underlying screw 24.
In order that sliding more flexibly, the sliding part 21 of the slide bar 13 is curved, and the bottom of arc is arranged down.
As another embodiment, as figs 11-13, the elastic component is reset jump ring 25, the reset jump ring 25
Be fixed on guide block 5, be provided with reset jump ring 25 one section of arc convex 26 for provide power upwards, buckle handle 12 in lift
On be provided with arc sections 27, the arc sections 27 and 26 tangent connection of arc convex, arc sections 27 can be with automatic needle-foot-lifting device
Action move on the arc convex 26 of reset jump ring 25, reset jump ring 25 provides reset force when sewing machine is normally sewed,
Retentivity is provided during automatic needle-foot-lifting device presser foot lifter.
That is：In normal sewing, the be supplied to torque for lifting handle 12 of buckling of reset jump ring 25 is for counterclockwise.
When lift presses through journey, the be supplied to torque for lifting handle 12 of buckling of reset jump ring 25 is for clockwise.
One end of the reset jump ring 25 of the present embodiment is fixed on guide block 5, and the other end is vacantly arranged.As shown in FIG., originally
The reset jump ring 25 of embodiment is L-shaped, and wherein vertical portion is fixed on the lateral surface of guide block 5, and horizontal part is (with arc convex
26) part is located in the upper plane of guide block 5.
Used as another embodiment, as shown in figure 14, the elastic component is spring 28, and spring is arranged on guide block) on, in bullet
The upper end of spring 28 is provided with the outer housing 29 that end is sphere, on handle 12 is buckled in lift is provided with arc sections 27, the arc sections 27 with
The sphere-contact connection of outer housing 29, outer housing 29 provides a power upwards by spring 28, and arc sections 27 can be with auto lifting
The action of foot device is moved on the sphere of outer housing 29, and arc sections 27 and the tangent setting of the sphere of outer housing 29, and spring 28 exists
Reset force is provided when sewing machine is normally sewed, retentivity is provided during automatic needle-foot-lifting device presser foot lifter.
Certainly, the top surface of outer housing 29 can also be plane.In actual application, the requirement to spring 18 is uprised, and one
Root spring 18 possibly cannot be realized, using two or three springs.
The present invention is coordinated with auxiliary body jointly by holding meanss, under the premise of keeping process time become, is led to
Crossing increases holding meanss, auxiliary body for the lost power of supplemental current reduction, reduces electrical current, efficiently controls and send out
Heat, reduces temperature, it is ensured that presser feet electric magnet 2 normally completes the action of presser foot lifter.
