A square groove is opened inside the box body 1, and the push plate 401 is slidably connected inside the square groove. A first sliding groove is opened at one end of the square groove away from the inner box 2. The first sliding grooves are fixed to two and are symmetrically arranged. The rectangular block 403 is slidably connected inside the first sliding groove. One end of the first spring 402 is installed on the outer surface of the rectangular block 403, and the other end of the first spring 402 is installed at one end of the push plate 401. A locking groove is opened at one end of the rectangular block 403 close to the first limiting member 301, and the first limiting member 301 is slidably connected inside the locking groove.

[0030] Rotating grooves are opened on one side of the two rectangular blocks 403 away from the locking groove. A groove 102 is opened on the outer surface of the box body 1, and the groove 102 and the rotating groove form a placement groove, and the grip 404 is rotatably connected inside the placement groove.

[0031] The square groove communicates with the placement cavity 101. A first circular groove is opened at one end of the square groove away from the placement cavity 101. The first circular grooves are fixed to two and are symmetrically arranged. One end of the second spring 405 is installed at the end of the push plate 401 away from the placement cavity 101, and the other end of the second spring 405 is installed inside the first circular groove.

[0032] A second circular groove is opened at one end of the square groove away from the placement cavity 101. A through groove is opened on the outer surface of the push plate 401, and a third circular groove is opened on the outer surface of the inner box 2. The second circular groove, the through groove and the third circular groove form a first limiting groove, and the second limiting member 406 is slidably connected inside the first limiting groove. One end of the second limiting member 406 is installed inside the second circular groove.

[0033] A second sliding groove is opened at one end of the push plate 401, and the push block 407 is slidably connected inside the second sliding groove. One end of the third spring 408 is installed inside the second sliding groove, and the other end of the third spring 408 is installed on the outer surface of the push block 407. A third sliding groove is opened on the outer surface of the box body 1, and the third sliding groove and the second sliding groove form a second limiting groove, and the third limiting member 409 is slidably connected inside the second limiting groove.

[0034] The outer surface of the box body 1 is provided with a fourth sliding groove, the fourth sliding groove is communicated with the second limiting groove, the slider 4010 is slidably connected to the inside of the fourth sliding groove, one end of the slider 4010 close to the second limiting groove is provided with a fifth sliding groove, one end of the third limiting member 409 abuts against the inner surface of the fifth sliding groove, the inside of the box body 1 is provided with a sixth sliding groove, the sixth sliding groove is communicated with the fifth sliding groove, the limiting block 4011 is slidably connected to the inside of the sixth sliding groove, a fourth spring 4012 is installed inside the sixth sliding groove, the fourth spring 4012 is fixed into two and symmetrically arranged, the other ends of the two fourth springs 4012 are both installed on the outer surface of the limiting block 4011, and the outer surface of the limiting block 4011 abuts against the outer surface of the slider 4010.

[0035] During use, first push the limiting block 4011 upward and then move the slider 4010 in the direction close to the limiting block 4011. Since the third limiting member 409 is disengaged from the restriction of the slider 4010, the push block 407 driven by the third spring 408 pushes the push block 407 out of the second sliding groove. Then pull the handle 404 away from the box body 1 so that the first limiting member 301 can lift the box cover 3 upward to disengage from the locking groove. When the box cover 3 is placed flat, since the third limiting member 409 is disengaged from the push plate 401 and the inner box 2 is not restricted by the box cover 3, the push plate 401 is pushed out of the inner box 2 by the thrust of the second spring 405. Then the item can be put back into the inner box 2. After putting the item back, first push the inner box 2 into the placement cavity 101 so that the push plate 401 enters the inside of the square groove. Then push the third limiting member 409 into the inside of the second sliding groove and then push the slider 4010 back to its original position. The limiting block 4011 moves downward under the thrust of the fourth spring 4012 and abuts against the slider 4010. After that, wrap the box cover 3 around the box body 1 and then pull the handle 404 away from the box body 1. When the first limiting member 301 enters the inside of the locking groove and then release the handle 404, due to the pulling force of the first spring 402, the rectangular block 403 retracts toward the box body 1 to complete the locking of the box body 1 to the box cover 3. Then put the handle 404 back into the groove 102 to complete the placement of the item.
