[0060] In the embodiment, the box body 2 includes two long edges and two short edges, which are arranged perpendicularly to form a ring-shaped box body 2 with an empty cavity. The sliding groove 202 is arranged on the long edge, as shown. Figure 1

[0061] In the embodiment, the height of the first sliding member and the second sliding member is equal to the depth of the sliding groove 202.​

[0062] In this embodiment, the thickness of the first blade 6 and the second blade 4 is 0.2 cm.

[0063] In this embodiment, the support platform is an L-shaped stepped structure formed by the slide groove 202 and the inner sidewall of the box 2, such as... Figure 5 As shown.

[0068] In this embodiment, the first slider 5 and the first blade 6, and the second slider 3 and the second blade 4 are all connected by welding.

[0069] In this embodiment, when cut perpendicularly along the length of the slide groove 202, the cross-sectional shapes of the first slider 5 and the second slide groove 202 are the same, such as... Figure 1 and Figure 4 As shown.

[0070] The thicknesses of the first blade 6 and the second blade 4 are thin, the length of the first sliding block 5 is equal to the length of the first blade 6, the thicknesses of the second sliding block 3 and the second sliding block 3 are equal to the thickness of the second blade 4, and the sizes of the first sliding block 5 and the second sliding block 3 are matched with the sizes of the sliding groove 202. When the first blade 6 and the second blade 4 are connected with the first sliding block 5 and the second sliding block 3 respectively, the sizes of the first sliding block 5 and the second sliding block 3 do not need to be changed to compensate for the error caused by the thicknesses of the first blade 6 and the second blade 4. However, in order to be more accurate, the width of the first sliding block 5 and the second sliding block 3 in this embodiment exceeds the width of the sliding groove by 0.2 cm to match the thicknesses of the first blade 6 and the second blade 4.

[0075] In this embodiment, the length of the arc-shaped clamping plate 801 matches the length of the sliding groove 202, and is equal to the length of the sliding groove 202.

[0076] In this embodiment, the width of the accommodating groove 803 is 0.2 cm greater than the wall thickness of the box body 2 without the sliding groove 202.

[0077] In this embodiment, the limiting plate 802 is provided with 20 limiting plates 802, and each limiting plate 802 is 1 cm long.
