[0041] ​The bottom plate 10 is substantially a rectangular flat plate member, the length direction of the bottom plate 10 is the first direction, the width direction is the second direction, and the thickness direction is the third direction. Two limiting blocks 30 are arranged at the two ends of the bottom plate 10 in the first direction, both of the two limiting blocks 30 are upwardly protruding, and the side surfaces of the two limiting blocks 30 towards the middle position of the bottom plate 10 are both spaced apart in the second direction and provided with a plurality of limiting grooves 31, the limiting grooves 31 extend along the third direction and the openings thereof are towards the middle position of the bottom plate 10, and meanwhile the ends of the limiting grooves 31 away from the bottom plate 10 are open, so as to facilitate the insertion of materials into the limiting grooves 31 from top to bottom. Between the two limiting blocks 30 of the bottom plate 10, the bottom plate 10 itself is formed with a plurality of stretching parts 11, and the number of the stretching parts 11 in the embodiment is two.

Through the cutouts 13, the bottom plate 10 will be elongated when subjected to a force outward in the first direction, and will be retracted when subjected to a force inward in the first direction in the elongated state, so as to realize the adjustment of the length dimension of the bottom plate 10 in the first direction.

[0042] The bottom plate 10 is formed with a spacing part 12 between the stretching parts 11, and a supporting block 20 can be arranged on the spacing part 12. In the embodiment, three supporting blocks 20 are arranged, which are respectively located between the two stretching parts 11 and close to the two limiting blocks 30. A plurality of supporting grooves 21 are arranged on the supporting block 20 along the second direction, the openings of the supporting grooves 21 are upwardly and both ends thereof in the first direction are in open state, and meanwhile the positions of each supporting groove 21 on each supporting block 20 in the second direction one by one correspond to the positions of the limiting grooves 31.

[0043] Since the bottom plate 10 can be elongated and retracted in the first direction, the size of the bottom plate 10 in the first direction can be adjusted by applying force to the bottom plate 10, so that the support can be adapted to materials with different size specifications in the first direction.

[0044] The arrangement of the cutouts 13 will be described in detail below.

[0045] The cutout 13 is in a bent arc or broken line shape in a projection plane perpendicular to the third direction, and is divided into a first cutout 13113 and a second cutout 13213 according to the opening direction of the bending, the first cutout 13113 opens towards the first end of the first direction, and the second cutout 13213 opens towards the second end of the first direction; in the stretching unit 110, the first cutout 13113 and the second cutout 13213 are arranged repeatedly along the second direction.

[0046] And in the stretching unit 110, the adjacent first cutout 13113 and the second cutout 13213 are staggered. In each of the stretching units 110, each first notch and second notch correspond one-to-one in position in the second direction.

[0047] Wherein, referring to Figure 2 and Figure 4 In this embodiment, the cutout 13 is continuously provided with a first section 41, a second section 42, a third section 43, a fourth section 44 and a fifth section 45 along the second direction, the first section 41 and the fifth section 45 extend along the first direction and are located at both ends of the cutout 13 in the second direction, the third section 43 extends along the second direction and is staggered with the first section 41 and the second section 42, the second section 42 extends obliquely and connects the adjacent ends of the first section 41 and the third section 43, and the fourth section 44 extends obliquely and connects the adjacent ends of the third section 43 and the fifth section 45; the cutout 13 is formed in a bent broken line shape by cooperation of the first section 41, the second section 42, the third section 43, the fourth section 44 and the fifth section 45.

[0048] Specifically, referring to Figure 2 and Figure 3 , Figure 2 is a schematic view of the cutout 13 in a closed state, Figure 3 is a schematic view of the cutout 13 in an open state, corresponding to the retracted state and the elongated state of the bottom plate 10 respectively. In addition, referring to Figure 4 and Figure 5 , they are Figure 2 and Figure 3 respectively, Figure 4 shows the specific shape of the cutout 13, Figure 5 shows the through hole 14 formed when the cutout 13 is opened.

[0049] In this embodiment, the cutout 13 can be cut on the bottom plate 10 by a vertically arranged cutter. Since the bottom plate 10 is made of foam material, the bottom plate 10 has a certain deformation capacity. The edge of the cutout 13 can deform under stress and change from a closed state to an open state, and still remain stable in the open state. The shape of the cutout 13 in the projection plane perpendicular to the third direction is approximately bent, so it has an opening. According to the opening direction, the cutout 13 is divided into a first cutout 13113 and a second cutout 13213. Referring to Figure 2 , the first cutout 13113 has an opening direction upward in the first direction, and the second cutout 13213 has an opening direction downward in the first direction. In the second direction, adjacent first cutouts 13113 and second cutouts 13213 are arranged alternately. Here, the alternately arranged means that first cutouts 13113 are arranged at a certain distance apart along the second direction first, and then second cutouts 13213 are arranged at a certain distance apart along the second direction at a position above the first cutout along the first direction, and the two arms of each second cutout 13213 extend into the opening positions of two first cutouts 13113 adjacent thereto.

[0050] For example, referring to Figure 4 , the cutout 13 is formed by five straight line segments connected in sequence. Taking a group of cutouts 13 as an example, the first segment 41 and the second segment 42 of the second cutout 13213 fall into the first cutout 13113 on the left side in the second direction, the fourth segment 44 and the fifth segment 45 fall into the first cutout 13113 on the right side in the second direction, and the third segment 43 is located between two adjacent first cutouts 13113.

The stretchable portion 11 is provided with a stretchable unit 110, and the stretchable unit 110 is provided with a plurality of through cutouts 13. By applying an outward force to the bottom plate 10 along the first direction, the cutouts 13 can be opened, so that the bottom plate 10 is elongated in the first direction. At this time, by applying an inward force to the bottom plate 10 along the first direction, the cutouts 13 can be restored to their original shape, so that the bottom plate 10 is shortened in the first direction to its original size. In this way, the size of the bottom plate 10 in the first direction can be adjusted according to actual needs, so as to adjust the distance between the two limiting blocks 30, so that the support can be adapted to different sizes of materials, reducing production cost.
