The inner wall of the through hole 15 is provided with a plurality of limit grooves 16 for the limit rod 14 to slide and pass through, and the limit grooves 16 are arranged along the circumferential direction of the inner wall of the through hole 15.
Referring to fig. 8, the limit groove 16 includes a first sub groove 161, a second sub groove 162, a third sub groove 163, and a fourth sub groove 164. The first sub-groove 161, the second sub-groove 162, the third sub-groove 163 and the fourth sub-groove 164 are inclined gradually from one end to the other end, far away from the limiting block 937, and one end of the first sub-groove 161, the second sub-groove 162, the third sub-groove 163 and the fourth sub-groove 164, which is close to the second connecting plate 92, is a high end, and one end of the first sub-groove 161, the second sub-groove 162, the third sub-groove 163 and the fourth sub-groove 164, which is far away from the second connecting plate 92, is a low end.
The lower end of the first sub groove 161 communicates with the lower end of the second sub groove 162, and the distance between the upper end of the first sub groove 161 and the second connection plate 92 is smaller than the distance between the upper end of the second sub groove 162 and the second connection plate 92. The high end of the third sub groove 163 communicates with the high end of the first sub groove 161, and the high end of the fourth sub groove 164 communicates with the high end of the second sub groove 162.

The implementation principle of the adjustable driving arm structure of the weft knitting machine in the embodiment of the application is that the limiting rod 14 is initially positioned in the third guide groove 19, and the limiting block 937 and the second gasket 938 are pushed away from each other by the second spring 936, and the limiting block 937 drives the sliding rod 935 to move, so that the limiting rod 14 is tightly abutted against the top end of the third guide groove 19.
Because the high end of the first sub-slot 161 is close to the second connecting plate 92, when the limit rod 14 is at the top end of the third guide slot 19, the distance between the limit block 937 and the second spacer 938 is far, and the elastic force of the second spring 936 between the limit block 937 and the second spacer 938 is small, so that the first connecting plate 91 and the second connecting plate 92 are loosened, and further the relative movement of the first connecting plate 91 and the second connecting plate 92 is facilitated, and the length of the driving arm structure is adjusted.
After the length of the driving arm structure is adjusted, the limiting block 937 is pressed, and the limiting block 937 drives the sliding rod 935 to be inserted into the through hole 15, so that the limiting rod 14 is propped against the inner wall of the third guiding groove 19 to slide downwards, and then the limiting rod 14 enters the first sub-groove 161. After the limit lever 14 enters the first sub-groove 161, the limit lever 937 is kept pressed, so that the limit lever 14 enters the first guide groove 17 from the first sub-groove 161.

Since the high end of the second sub-slot 162 is far from the second connection plate 92, when the limit lever 14 is at the top end of the second guide slot 18, the distance between the limit block 937 and the second spacer 938 is close, and the elastic force of the second spring 936 between the limit block 937 and the second spacer 938 is large, so that the first connection plate 91 and the second connection plate 92 abut against each other, and further the relative movement of the first connection plate 91 and the second connection plate 92 is conveniently limited.
The elastic force of the second spring 936 can be adjusted by pressing the limiting block 937 through the matching among the first sub-groove 161, the second sub-groove 162, the third sub-groove 163, the fourth sub-groove 164, the first guide groove 17, the second guide groove 18, the third guide groove 19 and the fourth guide groove 20, so that the first connecting plate 91 and the second connecting plate 92 can be conveniently controlled to be tightly abutted or loosened.
