[0202] As an optional embodiment, in order to precisely adjust the position of the size member 4:

[0203] The needle fixing plate 41 is provided with a plurality of circular holes 411, 412 and 413. Corresponding to:

[0204] The floating plate 3 has a plurality of rows of control holes 31 arranged in a first direction, each row of through holes 31 having a plurality of scale numbers around it. The first positioning rod 23 is inserted through the rows of through holes 31 into one of the circular holes (412, 413) of the fixed needle plate 41, positioning the sizing member 4 in the T-slot 37. The position of the rows of through holes 31 into which the first positioning rod 23 is inserted varies, resulting in a different positioning position of the sizing member 4 in the T-slot 37. The sizing member 4 is inserted into the T-slot 37. The first positioning rod 23 is inserted through the rows of through holes 31 on the floating plate 3 into the circular holes (412, 413) on the fixed needle plate 41, positioning the sizing member 4 in the T-slot 37 of the floating plate 3. The rows of through holes 3.1 on the floating plate 3 have scale numbers at different positions, allowing the desired position of the sizing member 4 to be achieved by selecting a hole with a different number for insertion. Each row of through holes has a plurality of holes arranged in a corresponding order for the first positioning rod 23 to be inserted.

[0205] As an optional embodiment, for the quick replacement and disassembly of the size member 4 and to prevent the first positioning rod 23 from falling off:

[0206] The positioning and dotting device includes: a first spring plate seat 8-1, a second spring plate seat 8-2 and a spring plate 9;

[0208] The first elastic piece seat 8-1 and the second elastic piece seat 8-2 are located at both ends of the plurality of rows of through holes 31;

[0209] Among them, the spring clip 9 is long and strip-shaped, and the first end of the spring clip 9 is rotatably connected to the first spring clip seat 8-1; under the action of external force, the second end of the spring clip 9 rotates to the second spring clip seat 8-2. When the two ends of the spring clip 9 and the second spring clip seat 8-2 are locked, the spring clip 9 blocks the upper end of the first positioning rod 23 to prevent the first positioning rod 23 from falling.

[0210] Specifically, taking the first spring clip holder 8-1 as an example, the floating plate 3 is provided with a locking hole 33, and the first spring clip holder 8-1 is provided with a spring clip holder through hole 81. The screw 22 passes through the spring clip holder through hole 81 and enters the locking hole 33, securing the first spring clip holder 8-1 to the floating plate 3. The first spring clip holder 8-1 is also provided with an axial hole 82. The first end of the spring clip 9 is provided with a first circular hole 91 and a ring 92 surrounding the first circular hole 91. The ring 92 is inserted into the axial hole 82. The first circular hole 91 and the axial hole 82 are coaxial. The screw 25 passes through the first circular hole 91 and the ring 92 and enters the axial hole 82. The spring clip 9 can rotate around the screw 25. When rotated until the second circular hole 93 is aligned with the axial hole of the second spring clip holder 8-2, the spring clip 9 is locked.

[0211] The screw 25 does not lock the spring piece 9, but is pressed against the floating plate 3, so the ring 92 of the spring piece 9 rotates about the axis, lifting the second end of the unlocked spring piece 9, forcing the spring piece 9 to bend and lift up and then swing to the second spring piece seat 8-2. The ring at the second end of the spring piece 9 can be quickly and effectively inserted into the axial hole of the second spring piece seat 8-2, so that the swing of the spring piece 9 is limited, and the spring piece 9 covers the first positioning rod 23 to prevent the first positioning rod 23 from falling off.

[0212] As an optional embodiment, to improve the precision fit between the scale base and the scale block:
