The purpose of this utility model is to provide a kind of easy and simple to handle, the seam of also scalable pressure foot lifting amount during sewing
Thread dynamo-electric sub- governor motion.
The purpose of this utility model is achieved in that the mechanism of electrical adjustment sewing-machine foot lifting capacity, wherein, including
Support, the lower end of described support is provided with motor, and the upper end both sides of described support are respectively provided with a bearing, are provided with described motor
Band brake apparatus, described motor is connected with active synchronization wheel, and equipped with driven shaft on bearing described in two, described driven shaft is put in level
Put, described driven shaft is fixed with driven synchronizing wheel and wobble crank, between described active synchronization wheel and described driven synchronizing wheel
It is provided with Timing Belt, the described wobble crank other end is connected with presser feet connecting rod, described support desktop is provided with and turns for controlled motor
Dynamic panel.
The mechanism of electrical adjustment sewing-machine foot lifting capacity mentioned above, wherein, described motor can positive and negative rotation, institute
State panel and be provided with rotating forward button and reversion button, control the change of pressure foot lifting amount by rotating forward button and reversion button
Change.
The mechanism of electrical adjustment sewing-machine foot lifting capacity mentioned above, wherein, is provided with electron number in described panel
Code enumerator, can freely set the rotation number of turns of motor.
The mechanism of electrical adjustment sewing-machine foot lifting capacity mentioned above, wherein, the radius of described active synchronization wheel is little
In the radius of described driven synchronizing wheel, to reduce the speed that driven synchronizing wheel rotates, thus improving the regulation essence of this governor motion
Degree.
This utility model projects compared to existing technology and beneficial has the technical effect that during sewing also scalable presser feet
Lifting capacity, by by upper and lower adjusting key, easily realize, operating process simple it is easy to left-hand seat, ordinary sewing work just can stitched
One-handed performance is realized during system.

Specific embodiment
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, referring to Fig. 14: electrical adjustment
The mechanism of sewing-machine foot lifting capacity, wherein, includes support 1, the lower end of described support 1 is provided with motor 2, described support 1
Upper end both sides are respectively provided with a bearing 3, are provided with band brake apparatus in described motor 2, and described motor 2 is connected with active synchronization wheel 4,
Equipped with driven shaft 5 on bearing 3 described in two, described driven shaft 5 is in horizontal positioned, and described driven shaft 5 is fixed with driven synchronizing wheel 6
With wobble crank 7, between described active synchronization wheel 4 and described driven synchronizing wheel 6, it is provided with Timing Belt 8, described wobble crank 7 is another
End is connected with presser feet connecting rod 9, and described support 1 desktop is provided with the panel 10 rotating for controlled motor 2.
Optimize further, wherein, described motor 2 can positive and negative rotation, described panel 10 be provided with rotating forward button 11 He
Reversion button 12, controls the change of pressure foot lifting amount by rotating forward button 11 and reversion button 12.
Working condition: when needing to adjust pressure foot lifting amount, press rotating forward button 11 or reversion button 12, now motor 2 leaves
Beginning work, active synchronization wheel 4 is rotated, and then drives driven synchronizing wheel 6 to rotate by Timing Belt 8, due to driven synchronizing wheel 6
It is fixed on driven shaft 5, driven shaft 5 therefore can be driven to rotate, driven shaft 5 drives on wobble crank 7 fixed thereon carries out
Lower swing, rear wobble crank 7 drives presser feet connecting rod 9 to move up and down, and after regulating pressure foot lifting amount, then clicks rotating forward button 11
Or reversion button 12 closing motor.
Optimize further, wherein, in described panel 10, be provided with electronic digital enumerator 13, can freely set motor 2
Rotate the number of turns,
Working condition: according to the lifting capacity change adjusting presser feet, judge the required number of turns rotating of motor 2, then pass through electricity
Subnumber code enumerator 13 is configured, and when needing to adjust pressure foot lifting amount, presses rotating forward button 11 or reversion button 12, now electricity
Machine 2 is started working, and active synchronization wheel 4 is rotated, and then drives driven synchronizing wheel 6 to rotate by Timing Belt 8, due to driven same
