[0025] The bendable plate 3 is sequentially provided with a box cover 31, a front elastic bending part 32, a handle base plate 33, a rear elastic bending part 34 and a box bottom 35 from front to back, wherein the box cover 31, the handle base plate 33 and the box bottom 35 are all rigid plate parts, the rear side of the horizontal rigid base plate 2 is fixed by interlocking with the interlocking hole part of the box bottom 35 through the rear interlocking protrusion, so that the box bottom 35 completely seals the rear opening of the box body frame and forms a hidden space of the box body, and the handle part 6 is arranged on the handle base plate 33 and faces outward.

[0026] The bendable plate 3, the double reverse hook fastener 4, the vertical rigid base plate 5 and the horizontal rigid base plate 2 are combined to serve as the wide elastic bending area support structure, and specifically, in the embodiment, the double reverse hook fastener 4 and the vertical rigid base plate 5 are fixed by interlocking with the interlocking slot, so that the double reverse hook fastener 4 is fixed at the central position of the vertical rigid base plate 5, and the lower hook part 41 is located below the lower edge 51 of the vertical rigid base plate, the front and rear lower hook parts 41 of the double reverse hook fastener 4 face the rear side and are buckled with the front and rear lower buckle holes 21 of the horizontal rigid base plate 2, at this time, the lower edge 51 of the vertical rigid base plate abuts against the upper surface of the horizontal rigid base plate 2, so that the double reverse hook fastener 4 and the vertical rigid base plate 5 are stably and vertically fixed on the upper surface of the horizontal rigid base plate 2.

[0027] In order to make the upper hook portion 42 of the double reverse hook fastener 4 on the front side and the upper hook hole 331 of the handle base plate 33, and the upper left side wall hook 114, the upper right side wall hook 124 and the left side upper hook hole 332, the right side upper hook hole 333 of the handle base plate fixed to each other, the handle base plate 33 and the horizontal rigid base plate 2 are arranged separately upwards and downwards before the above-mentioned box bottom 35 completely seals the opening of the box body frame, and the pre-assembly of the upper hook portion 42 and the upper hook hole 331 is carried out, and then the rear side of the left side wall 11, the lower side wall 13, the right side wall 12 and the horizontal rigid base plate 2 are inserted and fixed through the insertion of the insertion block and the insertion hole of the box bottom 35, so as to avoid the misalignment of the upper hook portion 42, the lower hook portion 41 and the upper hook hole 331, the lower hook hole 21, which makes it difficult to assemble. This scheme is more suitable for the application of the wide elastic bending area support structure of the flexible but relatively low elastic extension effect plastic sheet bendable plate 3 in the combination of the box body or related box frame structure, and the setting scheme of the upper hook portion 42 and the lower hook portion 41 facing opposite to each other can ensure that the handle box is carried and transported by hand to shake the handle base plate 33, so that the upper hook hole 331, the lower hook hole 21 can correspond to the reverse misalignment of the upper hook portion 42, the lower hook portion 41 when the double reverse hook fastener 4 is translated forward and backward relative to the handle base plate 33 and the horizontal rigid base plate 2, so as to effectively keep the double reverse hook fastener 4 from effectively hooking the handle base plate 33 and the horizontal rigid base plate 2.

[0028] In order to further improve the assembly convenience, the elastic bending portion is provided with at least two groups of first type of notches 301 and second type of notches 302 arranged in sequence, at least two first notch junctions 303 are left uncut in the middle of the first type of notches 301, at least two second notch junctions 304 are left uncut in the middle of the second type of notches 302, and the first and second notch junctions (303, 304) are not located on the same straight line. Through this setting, the bendable plate 3 is provided with higher elastic extension effect, and by stretching the bendable plate 3, the front edge of the upper hook hole 331 is passed around the front end of the upper hook portion 42, and then under the elastic reset action of the front elastic bending portion 32 and the rear elastic bending portion 34, the upper hook hole 331 can be fixed with the upper hook portion 42. The operation process is simple and fast, and the elastic reset action can further improve the fixing effect.

[0029] The front and rear upper edge corners of the double anti-hook fastener 4 are set to correspond to the front and rear arc-shaped edges 43 and 44, respectively, and the front arc-shaped edge 43 is arranged in the same profile as the front arc-shaped upper edge (112, 122) and is aligned with it, and the rear arc-shaped edge 44 is arranged in the same profile as the rear arc-shaped upper edge (113, 123) and is aligned with it, so that the elastic bending part can be attached to the arc-shaped edges and the arc-shaped upper edges when it is bent. At this time, the box cover 31 can completely cover and close the opening of the box body, and then the sleeve column 81 provided on the box body and the elastic band 82 provided on the box cover 31 are sleeved with each other, and the insertion hole part 311 of the box cover 31 is inserted and matched with the first front insertion protrusion 22 of the horizontal rigid substrate 2, so that the box body and the box cover 31 are fixed to each other, and the assembly of the hand-held box is completed.

[0030] After the box body is covered and fixed, when the user lifts the box body, the gravity effect of the content contained in the box body and the box body can be realized by the upper hook part 42 and the lower hook part 41 of the double anti-hook fastener 4, which corresponds to the upper hook hole 331 of the handle substrate 33 and the lower hook hole 21 of the horizontal rigid substrate 2, to realize gravity bearing, so as to avoid that the elastic bending part of the bendable plate 3 is subjected to tension, which causes the box body to be deformed in structure or the weak structure to be broken or damaged, especially suitable for maintaining the structure of the scored-scored joint type elastic bending part of the bendable plate 3 used in the box body of the embodiment.

[0031] In order to reduce the influence of the box body structure caused by the shaking of the objects contained in the box body, a box inner partition plate 9 is further provided in the embodiment, and the box body partition plate is provided with a positioning groove 91; when the box inner partition plate 9 is fixed to each side wall of the box body, the positioning groove 91 is fixed to the lower hook part 41. Through the setting, the contained objects in the box body can be accurately placed into the partition hole according to the outer contour, so as to reduce the shaking range of the objects, and the positioning groove 91 and the lower hook part 41 are fixed to each other, which can effectively fix the double anti-hook fastener 4 and further prevent the horizontal side shift of the double anti-hook fastener 4.

[0033] When the box cover 31 is covered, since the first front insertion protrusion 22 protrudes outward from the surface of the stop frame 7, when the stop frame 7 is completely closed by the box cover 31, the insertion hole part 311 of the box cover 31 and the first front insertion protrusion 22 of the horizontal rigid substrate 2 can be insertion fitted. In the embodiment, the rotating buckle 83 arranged on the stop frame 7 and the locking hole 84 arranged on the box cover 31 are used as locking members, instead of the sleeve fitting column 81-elastic band 82 in the embodiment 1, and the same good locking effect can be achieved.

[0034] The hand-held box of the above-mentioned embodiments 1 or 2 can preferably have a width of 30cm-200cm, and is particularly suitable for being applied to a hand-held plastic box or a wooden box; of course, the width elastic bending area support structure can also be applied to other structures such as a decorative plate and a cover plate having an elastic bending part, so that the width of the elastic bending part is increased, and the influence of the tension in the elastic extension direction on the elastic bending part is reduced.
