The first axis hole 14；
Second main driving mechanism 2 includes the second lifting driver part 21 that lifting driving is carried out to rear tugboat, and to second
Lifting driver part 21 carries out the second push-and-pull driving part 22 of push-and-pull driving；Second push-and-pull driving part 22 passes through the second driving
Axis 23 is articulated with the second lifting driver part 21, and the second push-and-pull driving part 22 is formed with to match with the second drive shaft 23
The second axis hole 24 closed；
It further include the secondary driving mechanism 3 that presser feet 6 is operated alone；Secondary driving mechanism 3 includes to the first lifting driving
Component 11 carries out the secondary push-and-pull driving part 31 of push-and-pull driving；
First axis hole 14 is formed with when pair push-and-pull driving part 31 carries out push-and-pull driving to the first lifting driver part 11
For the free movable space of the first drive shaft 13.The present invention separately sets the secondary driving mechanism 3 that presser feet 6 is operated alone, in reality
During the use of border, main driving mechanism can synchronize presser feet 6 and rear tugboat driving, and secondary driving mechanism 3 can be when needed
Presser feet 6 is operated alone, making cloth always has rear dragging wheel to push down, and cloth is not easy play dislocation and influences sewing.Specific behaviour
As main driving mechanism drives presser feet 6 by the first main driving mechanism 1, by the second main driving mechanism 2 to rear tugboat
It is driven；First main driving mechanism 1 drives the first lifting using the first drive shaft 13 by the first push-and-pull driving part 12
Component 11 carries out push-and-pull driving, and the second main driving mechanism 2 is by the second push-and-pull driving part 22 using the second drive shaft 23 to the
Two lifting driver parts 21 carry out push-and-pull driving, and when presser feet 6 is operated alone in secondary driving mechanism 3, secondary driving mechanism 3 is logical
It crosses secondary push-and-pull driving part 31 replacement the first push-and-pull driving part 12 and push-and-pull driving is carried out to the first lifting driver part 11, in turn
The first lifting driver part 11 is set to carry out lifting driving to presser feet 6, in pair push-and-pull driving part 31 to the first lifting driver part
During 11 carry out push-and-pull driving, the first drive shaft 13 using the first axis hole 14 redundant space carry out freely activity without by
The influence of driving part 12 is pushed and pulled to the first axis hole 14 and first.
Preferably, secondary push-and-pull driving part 31 is articulated in one by the first drive shaft 13 and the first lifting driver part 11
It rises.I.e. secondary push-and-pull driving part 31 and first pushes and pulls driving part 12 and shares the first drive shaft 13, and structure is simpler compact.
Preferably, the first axis hole 14 is strip-shaped hole, and pair push-and-pull driving part 31 is pushed and pulled along the length direction of the first axis hole 14
First drive shaft 13.This structure can be such that the first axis hole 14 and the path of the first drive shaft 13 matches, and driving part is pushed and pulled in pair
31 when driving the first lifting driver part 11 using the first drive shaft 13, will not be pushed and pulled by the first axis hole 14 and first
The influence of driving part 12, flexible movements are smooth.
In order to more particularly realize the structure of secondary driving mechanism 3, it is preferable that pair push-and-pull driving part 31 is strip structure
(strip structure concretely the structures such as the cylindrical bar of strip sheet body or strip, polygon rod)；Secondary driving mechanism 3 further includes

Swing part 321 generates the wobbling action that push-and-pull driving is carried out to secondary push-and-pull driving part 31；Pair push-and-pull driving part 31 have with
First power intake 311 of the first swing part 321 connection, and the first power output for being connect with the first lifting driver part 11
End 312；First swing part 321 is articulated by third drive shaft 323 and the first power intake 311；Secondary driving part
The first swing pivot shaft 324 is equipped between 32 both ends.In actual use, secondary power plant 33 is to secondary driving portion
Part 32 carries out wobble drive, so that the first swing part 321 is generated as fulcrum by the first swing pivot shaft 324 and is driven to pair push-and-pull
Dynamic component 31 carries out the wobbling action of push-and-pull driving, and then secondary push-and-pull driving part 31 pushes away the first lifting driver part 11
Draw driving.This structural principle is ingenious, simple in structure, and action is smooth.
Preferably, the first swing pivot shaft 324 is set to the bending place of secondary driving part 32.This structure can increase the first pendulum
The balanced amplitude of fluctuation of dynamic 321 and second swing part 322 of portion, and enhance flexible swinging.
Preferably, the first swing pivot shaft 324 is equipped with the bearing being connect with sewing machine main body (not shown)
3241.I.e. the first swing pivot shaft 324 is carried by bearing 3241, more firm stable.
Preferably, secondary power plant 33 has secondary power output rod 331 vertically arranged from top to bottom, pair push-and-pull driving portion
Part 31 is transversely arranged, and the first swing part 321 is arranged upward, and the second swing part 322 pushes and pulls driving portion towards laterally setting and with pair
The direction of part 31 on the contrary, and the end of the second swing part 322 be formed with corresponding holding below 331 end of secondary power output rod
Power portion 3221.In actual use, secondary power plant 33 downwards carries out load portion 3221 using secondary power output rod 331
It drives, makes the second swing part 322 that the first swing part 321 be driven to be swung, drive secondary push-and-pull driving part 31 in close level
Push pull maneuver is carried out on direction.
In order to realize the concrete structure of secondary driving part 3, it is preferable that secondary driving part 3 is sheet body structure, load portion 3221
For the transversal piece structure perpendicular with 33 place plane of secondary driving part.This is simple in structure, easy to make, at low cost.
Preferably, the first lifting driver part 11 is in bending, includes the third swing part 111 driven to presser feet 6
With the 4th swing part 112 being connect with the first drive shaft 13, after the 4th swing part 112 is driven by the first drive shaft 13, third
Swing part 111 generates the wobbling action that lifting driving is carried out to presser feet 6；Third swing part 111 passes through the 4th drive shaft 113 and pressure
Foot 6 is articulated；The second swing pivot shaft 114 is equipped between the both ends of first lifting driver part 11；
Second lifting driver part 21 is in bending, includes the 5th swing part 211 driven to rear tugboat and with the
6th swing part 212 of two drive shafts 23 connection, after the 6th swing part 212 is driven by the second drive shaft 23, the 5th swing part
211 generate the wobbling action that lifting driving is carried out to rear tugboat；5th swing part 211 passes through the 5th drive shaft 211 and rear tugboat
It is articulated；Third swing pivot shaft 214 is equipped between the both ends of second lifting driver part 21.It was actually using
Cheng Zhong, the first drive shaft 13 carry out wobble drive to the first lifting driver part 11, and third swing part 111 is made to be swung by second
Pivot shaft 114 carries out lifting drive actions as fulcrum generation to presser feet 6.Second drive shaft 23 is to the second lifting driver part
21 carry out wobble drive, so that the 5th swing part 211 is generated as fulcrum by third swing pivot shaft 214 and are carried out to rear tugboat
Lift drive actions.This structural principle is ingenious, simple in structure, and action is smooth.
Preferably, the second swing pivot shaft 114 is set to the bending place of the first lifting driver part 11, third swing pivot
Shaft 214 is set to the bending place of the second lifting driver part 21.This structure can increase third swing part 111 and the 4th swing part
112 and the 5th swing part 211 and the 6th swing part 212 balanced amplitude of fluctuation, and enhance flexible swinging.
Preferably, the 4th drive shaft 113 is equipped with one end and is articulated with the 4th drive shaft 113, the other end and presser feet 6
The adapting rod 1131 being articulated.In actual use, adapter is used as by adapting rod 1131, the 4th driving can be played
