Description
Technical field
The utility model belongs to sewing device technical field, is related to a kind of spanner of falling feeding of sewing machine.
Background technique
When sewing machine does reinforcing sewing, the spanner of falling feeding is pressed, dress material will move round about；It unclamps feeding to pull
Hand, also known as spanner is backstitched, dress material will be mobile to positive direction, is repeated several times dress material and is just reinforced sewing several times.
A kind of sewing machine for backstitching spanner and moving to left structure as disclosed in 103993435 A of China patent CN comprising head
With backstitch spanner, spanner movable chamber and lubricating oil working chamber are formed in the cavity of head column, and cavity wall separates in passing through, in left and right
Distribution；The column frontal left that spanner outer end is located at head is backstitched, spanner inner end is backstitched and is located in spanner movable chamber, column front
Left side is offered for backstitching the loose slot that spanner vertically moves back and forth.
Although above-mentioned design allows user's operation Shi Shouyu to backstitch spanner apart from closer, but there are still following defects: existing
The spanner of falling feeding mostly use the integral structure of L-type greatly, and the inner end for the spanner of falling feeding is using the fixed ring being relatively large in diameter
Mode, be set on feed spool by the Fixing shrink ring, the outer end of the spanner of falling feeding passes through loose slot and extends to outside casing,
By L shape and the spanner of falling feeding with fixed ring passes through narrow loose slot, and difficulty is very big, in the prior art
The assembly difficulty for the spanner of falling feeding is very big, and if loose slot widened, it not only will affect the overall appearance of sewing machine, can also
Influence the performances such as the noise reduction of sewing machine, therefore, which and the big problem of the assembly difficulty that can't resolve the spanner of falling feeding.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of feeding of sewing machine
Spanner, the technical problem to be solved by the utility model is to how to reduce the assembly difficulty of this spanner of falling feeding.
