Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing to the present invention into
Row detailed description, the description of this part be only it is exemplary and explanatory, should not have any limitation to protection scope of the present invention
Effect.
As Figure 2-Figure 5, specific structure of the invention are as follows: a kind of new-type sewing machine backstitches mechanism automatically, and setting exists
Sewing machine side, it is described to backstitch hand including driving what is backstitched to backstitch shaft 91 and backstitch hand handle 90 with backstitch that shaft 91 is connected
It is actively set on and is backstitched in shaft 91 90, shaft lever 80, and shaft thick stick are fixedly installed in the axial end for backstitching shaft 91
80 one end of bar, which extends internally, the hand handle contact block 81 of convex, and hand handle contact block 81 is on the downside of the arm for backstitching hand handle 90；Institute
The other end side for stating shaft lever 80 is provided with connecting hole 83, and connection 7 one end of lever 84 is movably articulated in connection by shipping and reselling on another market
In hole 83；The connection lever 7 is fixed on sewing machine by fixing axle 6, and be fixed with can be upper and lower for the other end for connecting lever 7
Movable telescoping mechanism.
Referring to Fig. 1, structural schematic diagram is backstitched for existing sewing machine.In figure, the side of sewing machine, which is provided with, backstitches hand handle
90, and be fixedly installed with the shaft 91 that backstitches stretched out inside sewing machine；Spring is internally provided in sewing machine come to backstitching shaft
91 carry out reset operation.When needing to backstitch operation, manual pressure is needed to backstitch hand handle 90, driving backstitches shaft 91, to realize
Backstitch ex-situ operations.
Referring to such as 2, it is preferred that the telescoping mechanism of connection 7 end of lever connection includes: and connect what lever 7 was connected
Hinged telescopic 4 on force arm 5 and force arm 5, the telescopic 4 are connected to the guide rod 3 of flexible driving.
Preferably, described stretch is driven to cylinder 2.It is steadily using cylinder advantage, it is easy to maintain.
Preferably, 4 end of telescopic is movably hinged with guide rod 3.
Preferably, the flexible driving is movably fixed on the adjustable movable guiding rail 1 of vertical direction.
Preferably, the 90 top extreme higher position of hand handle that backstitches is provided with block 93.
Preferably, described to backstitch the spring 92 being connected in hand handle 90 for return.
Preferably, the connecting hole 83 on the connection lever 7 is kidney-shaped pore structure.
Be schematic front view of the present invention referring to Fig. 3 when specifically used: it is arranged falls in sewing machine side, including driving
Seam backstitches shaft 91 and backstitches hand handle 90 with backstitch that shaft 91 is connected, it is described backstitch hand handle 90 and be actively set on backstitch shaft 91
On, shaft lever 80 is fixedly installed in the axial end for backstitching shaft 91, and 80 one end of shaft lever extends internally protrusion
The hand handle contact block 81 of shape, and hand handle contact block 81 is on the downside of the arm for backstitching hand handle 90；The another side of the shaft lever 80
Face is provided with connecting hole 83, and connection 7 one end of lever 84 is movably articulated in connecting hole 83 by shipping and reselling on another market；The connection lever 7 is logical
It crosses fixing axle 6 to be fixed on sewing machine, and connects the fixed force arm 5 of the other end of lever 7, and articulated on force arm 5 stretch
Contracting set 4, the telescopic 4 is connected to the guide rod 3 of 2 front end of cylinder.
Fig. 3 is shown as stationary state schematic diagram.It backstitches manually, state diagram when backstitching uniformly distributed work automatically.
Fig. 4 is working state schematic representation when present invention manual operation backstitches handle.When operation backstitches manually, presses and backstitch
Hand handle 90 backstitches hand handle 90 and pushes down lower section hand handle contact block 81, drives shaft lever 80 to rotate down, as shown in Figure 4；Meanwhile turning

Fig. 5 is working state schematic representation when the present invention backstitches automatically.It starts switch, and supplies about what is pneumatically backstitched in figure
Gas, power supply unit are omitted, and are not key contents of the invention, and the prior art can be implemented more easily.
In Fig. 5, after switch (generally can be set to foot-operated or knee side pressure type) starting, the driving of cylinder 2 is led
Bar 3 moves downward, and guide rod 3 compresses telescopic 4, and telescopic 4 drives force arm 5, and force arm 5 drives connection lever 7 downwardly together
Movement；Connecting lever 7 pulls shaft lever 80 to move (as shown in the figure)；At this point, shaft lever 80 falls also according to manual operation
It is equally moved when stitching handle, but backstitches handle 90 and limited at this time by spring 92 and block 93, position is motionless.
Operation is backstitched automatically in this way, realizing.So the time can be saved, operative employee has been vacateed to avoid manual operations
Both hands, be convenient for other operations, production efficiency is higher.
It should be noted that, in this document, the terms "include", "comprise" or its any other variant are intended to non-row
His property includes, so that the process, method, article or equipment for including a series of elements not only includes those elements, and
And further include other elements that are not explicitly listed, or further include for this process, method, article or equipment institute it is intrinsic
Element.
Used herein a specific example illustrates the principle and implementation of the invention, the explanation of above example
It is merely used to help understand method and its core concept of the invention.The above is only a preferred embodiment of the present invention, it answers
When pointing out due to the finiteness of literal expression, and objectively there is unlimited specific structure, for the common skill of the art
For art personnel, without departing from the principle of the present invention, several improvement, retouching or variation can also be made, can also incited somebody to action
Above-mentioned technical characteristic is combined in the right way；These improve retouching, variation or combination, or the not improved structure by invention
