It is symmetrical arranged with three-arc section 315.
When roller 33 is in contact with the first arc section 313 of cam circumferential surface 311, driving crank 32 is failure to actuate, and presser feet is
The state put down, in this state, lockstitch button holder perform sewing action and trimming action.When the of roller 33 and cam circumferential surface 311
When two arc sections 314 are in contact, driving crank 32 fixes swing pivot O2 clockwise oscillations around second, and driving crank 32 is by turning
Fitting 34 drives swing rod 40 to fix swing pivot O1 counter-clockwise swings around first, and swing rod 40 drives presser feet to lift by driving member 50
Oscillating rod 62 fixes swing pivot O3 counter-clockwise swings around the 3rd, is driven under the action of guide groove 641 and sliding block 651 cooperate
Dynamic pressure foot lifting linking member 63 and stent 65 move upwardly together, and presser bar 61 and presser feet is driven synchronously to move up, and realize lift
Presser feet.When roller 33 is in contact with the three-arc section 315 of cam circumferential surface 311, driving crank 32 is fixed around second and swings branch
Point O2 counter-clockwise swings, driving crank 32 drive swing rod 40 to be put clockwise around the first fixation swing pivot O1 by adapter 34
Dynamic, swing rod 40 drives presser feet lifting and swinging bar 62 to fix swing pivot O3 clockwise oscillations around the 3rd by driving member 50, is leading
Under the action of slot 641 and the mutual cooperation of sliding block 651 presser feet lifting linking member 63 and stent 65 is driven to move downwardly together, driving pressure
Foot lever 61 and presser feet synchronously move down, and realization bleeds off pressure foot.Therefore, the first arc section 313 be presser foot lifter idle stroke section, second
Arc section 314 is presser foot lifter trip segment, and three-arc section 315 is to bleed off pressure foot trip segment.
The application also provides a kind of lockstitch button holder, as shown in figure 9, including casing 10, as above institute is equipped in the casing 10
The presser foot lifter driving mechanism stated.
In conclusion this application involves presser foot lifter driving mechanism and with the presser foot lifter driving mechanism lockstitch button holder, drive
Dynamic motor 20 uses vertically-mounted structure, and is all built in casing 10 with rotating member 31, therefore foot lifting mechanism easy to implement
A driving motor 20 and output shaft are shared with other mechanisms, and then reduces cost, and overall structure is simple, compact, suitable interior
It puts, lockstitch button holder complete machine is made to seem more aesthetically pleasing；Particularly, the design of adapter 34 is while mechanism kinematic is met, moreover it is possible to have
Effect prevents mechanism blockage, greatly improves the reliability and stability of mechanism action.
