Of course, the inventive gauge may be used to stitch a collar piece and a collar of a body, or to stitch a waistband and a skirt, in addition to being used to stitch a sleeve.

Referring to fig. 1 to 3, the utility model discloses a gauge applied to a sewing machine, wherein the gauge 1 comprises a fixing plate 11, a first baffle 12 and a second baffle 13, the fixing plate 11 comprises a front surface 111 and a bottom surface 112 which are opposite along a first direction, and the bottom surface 112 is used for being attached to a machine body of the sewing machine. The first baffle 12 is disposed on a first side edge 113 of the fixed plate 11 and protrudes from the front surface 111. The second baffle 13 is disposed on a second side edge 114 of the fixing plate 11 and protrudes from the front surface 111, and the first side edge 113 and the second side edge 114 are disposed opposite to each other in a second direction.

For example, the first direction may be shown as an up-down direction in fig. 1, and the second direction may be shown as a left-right direction in fig. 1. Preferably, the first direction and the second direction are perpendicular.

It will be appreciated that the fixing plate 11 is used for being fixed to a sewing machine body, when the fixing plate 11 is fixed to the sewing machine body, the bottom surface 112 of the fixing plate 11 is attached to the sewing machine body, and the positions of the first baffle 12 and the second baffle 13 located on opposite sides of the fixing plate 11 relative to the sewing needle of the sewing machine are unchanged, so that when a worker sews the sleeve layer 31 on the front 111 of the sleeve 2, the front 111 of the sleeve layer 31 and the front 111 of the sleeve 2 can be placed towards the machine body, the reverse side of the sleeve layer 31 and the reverse side of the sleeve 2 face the worker, and then the sleeve layer 31 can be abutted against the outer side of the first baffle 12 or the second baffle 13 according to the thickness of the sleeve layer 31, as shown in fig. 3, so as to limit the movement of the sleeve layer 31 and the sleeve 2, and further enable the worker to see the sleeve layer 32 for line pressing (for example, pit line pressing or open line pressing). Because the first baffle 12 or the second baffle 13 limits the movement of the sleeve-shaped outer layer 31 and the sleeve 2, the distance from the needle falling position of the sewing needle of the sewing machine to the sewing position (shown by a dotted line in fig. 3) of the sleeve-shaped outer layer 31 and the sleeve 2 is consistent, the straightness of the sewing thread on the outer side of the garment is guaranteed, and in the process of the thread pressing, a worker can press the thread by looking at the sleeve-shaped inner layer 32, and the straightness of the sewing thread on the inner side of the garment is guaranteed. Meanwhile, the sewing thread on the outer side and the inner side of the garment is neat, the technical requirements on workers are reduced, the production difficulty of the garment is reduced, and the production efficiency of the garment is improved.

Specifically, if the heights of the first baffle 12 and the second baffle 13 are different in the first direction, the operator may select the thickness of the fabric of the sleeve-shaped outer layer 31 according to, for example, the thickness of the fabric of the sleeve-shaped outer layer 31, so that the sleeve-shaped outer layer 31 can be stably abutted against the outer side of the first baffle 12 or the second baffle 13 after being sewn and folded over with the sleeve 2, and the sleeve-shaped outer layer 31 and the sleeve 2 are restricted from moving.

In some embodiments, the height H1 of the first baffle 12 is 0.1cm to 0.2cm and the height H2 of the second baffle 13 is 0.3cm to 0.4cm in the first direction. For example, the height H1 of the first baffle 12 may be 0.1cm, 0.13cm, 0.15cm, 0.18cm, or 0.2cm, and the height H2 of the second baffle 13 may be 0.3cm, 0.33cm, 0.35cm, 0.38cm, or 0.4cm. Through making the height of first baffle 12, second baffle 13 along the first direction fall within above-mentioned within range, be favorable to adapting to the surface fabric of ordinary use, be favorable to controlling the height of first baffle 12 and second baffle 13 simultaneously, avoid the height of first baffle 12 and second baffle 13 too high and jack-up sleeve 2 surface fabric, influence the line ball.

In some embodiments, a side of the first baffle 12 facing away from the fixing plate 11 in the second direction has a first vertical surface 121, the first vertical surface 121 being perpendicular to the bottom surface 112.
