Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to attached drawing: this adjustable needle pitch structure in the present embodiment, including rack 1 are provided with needle pitch base 2 in rack 1,
It is provided with needle gage spanner 3 on needle pitch base 2, needle gage display board 4 is provided in rack 1, sliding slot 1, needle are provided on needle gage display board 4
One end away from spanner 3 is arranged in sliding slot 1.
The inside of needle gage display board 4 is provided with needle gage and falls along seam amplitude limit plate 6, and needle gage falls to be set along seam amplitude limit plate 6
It sets in rack 1, needle gage spanner 3 passes through needle gage and falls to be arranged on needle gage display board 4 along seam amplitude limit plate 6, and the one of sliding slot 1
Side is provided with sliding slot 27, and sliding slot 27 is arranged on needle gage display board 4, and sliding block 8 is provided in sliding slot 27, and sliding block 8 is arranged in needle
Away from along on seam amplitude limit plate 6.
Needle gage falls along sliding slot 39 is provided on seam amplitude limit plate 6, and needle gage spanner 3 passes through needle gage and falls along seam amplitude limit plate 6
On sliding slot 39 be arranged on needle gage display board 4.
The two sides of sliding slot 1 are provided with scale 10, and scale 10 is arranged on needle gage display board 4.
Needle gage spanner 3 slides in sliding slot 1, drives 2 angle change of needle pitch base, realizes needle gage adjustable effect.
Scale 10 on needle gage display board 4 shows the shift position of needle gage spanner 3.
It is as shown in Figure 2, Figure 3, Figure 4 to backstitch needle gage longest, needle gage spanner 3 pulls highest, band according to A arrow direction upwards
