[0044] In some embodiments, referring to Figure 2 、 Figure 6 and Figure 7 ,the two comb teeth bars 140 can be a first comb teeth bar 141 and a second comb teeth bar 142 that are parallel to each other, wherein the first comb teeth bar 141 is arranged below the second comb teeth bar 142. Specifically, the first comb teeth bar 141 is arranged at the lower edge of the first frame 110, and the second comb teeth bar 142 is arranged at the upper edge of the first frame 110; keyways are provided at both the upper edge and the lower edge of the first frame 110. A blind slot d is provided in the side positioning edge a of the first comb teeth bar 141, and the blind slot d is aligned with the keyway at the lower edge of the first frame 110 and is keyed through a square positioning key b, wherein the blind slot d serves to support the square positioning key b. Referring to Figure 7 and Figure 8 ,a through slot e is provided in the side positioning edge a of the second comb teeth bar 142, the keyway wedge edge at the upper edge of the first frame 110 abuts against the wedge edge of the wedge-shaped positioning key c, and the straight edge of the through slot e abuts against the straight edge of the wedge-shaped positioning key c. In this embodiment, the above method ensures that the first comb teeth bar 141 and the second comb teeth bar 142 can be firmly stressed in the first direction X.
[0045] Further, in the above embodiment, the wedge-shaped positioning key c can fine-tune the position of the second comb teeth bar 142 in the first direction X by adjusting its own height, so as to enable the first comb teeth bar 141 and the second comb teeth bar 142 to simultaneously engage with the gear teeth g on the moving seat 170 when the moving seat 170 moves upward.
[0046] In some embodiments, referring to Figures 5 to 7 , a plurality of comb teeth f are arranged in parallel along the first direction X on the comb rack 140, and the arrangement length of the plurality of comb teeth f is L1; a plurality of inserting teeth g are arranged in parallel along the first direction X on the moving seat 170, and the arrangement length of the plurality of inserting teeth g is L2, and L2 << L1.
