The two sliders 401 are respectively movably connected to both sides of the first box body 1. One side of the rotating shaft 403 close to the slider 401 is rotatably connected to the slider 401, and the rotating shaft 403 passes through the U-shaped frame 402 and is movably connected thereto. The external thread 404 is provided at one end of the rotating shaft 403 away from the slider 401, and the hexagon nut 405 is threadedly connected to the surface of the external thread 404.

[0030] In this embodiment: By providing the limiting component 4, the convex block 8 is moved into the concave block 7, enabling the quick alignment of the second box body 2 with the first box body 1. When the U-shaped frame 402 rotates to the outside of the second box body 2, it can limit the position of the second box body 2. The hexagonal nut 405 can rotate on the surface of the external thread 404. When the hexagonal nut 405 moves to an appropriate position, the hexagonal nut 405 can closely fit the surface of the U-shaped frame 402, thereby limiting the position of the U-shaped frame 402 and preventing the loosening and deviation of the U-shaped frame 402 during use.

[0031] Specifically, as Figure 1 、 Figure 3 、 Figure 4 shown, the fixing plate 501 is movably connected inside the U-shaped frame 402, and the surface of the fixing plate 501 close to the second box body 2 is made of rubber material.

[0032] Specifically, as Figure 3 、 Figure 4 shown, a moving screw 502 is rotatably connected to the front side of the fixing plate 501. The moving screw 502 penetrates through the U-shaped frame 402 and is threadedly connected thereto.

[0033] Specifically, as Figure 3 、 Figure 4 shown, limiting grooves 6 are provided on both sides of the inner wall of the U-shaped frame 402. A limiting block 503 is slidably connected inside the limiting groove 6. One side of the limiting block 503 close to the fixing plate 501 is fixedly connected to the fixing plate 501.

[0034] In this embodiment: By providing the fixing component 5, when the U-shaped frame 402 rotates to the outside of the second box body 2, the moving screw 502 is rotated. The moving screw 502 can drive the fixing plate 501 to move towards the second box body 2, enabling the fixing plate 501 to squeeze and fix the second box body 2, further improving the stability when the second box body 2 is connected to the first box body 1.

[0035] Specifically, as Figure 2 shown, a concave block 7 is fixedly connected to the front side of the first box body 1, and the number of the concave blocks 7 is set to two.

[0036] Specifically, as Figure 2 shown, a convex block 8 is fixedly connected to the rear side of the second box body 2. The convex block 8 is used in cooperation with the concave block 7.

[0037] In this embodiment: Through the above settings, when it is necessary to connect the second box body 2 to the first box body 1, only the second box body 2 needs to be moved to move the convex block 8 into the concave block 7, without lifting the first box body 1 or the second box body 2, improving the convenience during connection.

[0038] Specifically, as Figure 1 and Figure 2 shown, I-shaped blocks 9 are fixedly connected to both sides of the first box body 1, and the slider 401 is slidably connected to the surface of the I-shaped block 9.

[0039] Specifically, as Figure 5 shown, a fastening screw 10 is threadedly connected inside the slider 401, and the side of the fastening screw 10 close to the I-shaped block 9 is in close fit with the I-shaped block 9.

[0040] In this embodiment: Through the above settings, the slider 401 can slide flexibly on the surface of the I-shaped block 9. After sliding to any position, tightening the fastening screw 10 can fix the position of the slider 401, so that when the limiting component 4 is not in use, the limiting component 4 can be adjusted to an appropriate angle and an appropriate height, thereby improving the overall use effect.

[0041] Working principle: When it is necessary to connect the second box body 2 to the first box body 1, move the second box body 2 so that the convex block 8 moves into the concave block 7, and the second box body 2 and the first box body 1 can be quickly aligned. Then rotate the U-shaped frame 402. When the U-shaped frame 402 rotates to the outside of the second box body 2, it can limit the position of the second box body 2. Then rotate the hexagonal nut 405. The hexagonal nut 405 can rotate on the surface of the external thread 404. When the hexagonal nut 405 moves to an appropriate position, the hexagonal nut 405 can be in close fit with the surface of the U-shaped frame 402, so that the position of the U-shaped frame 402 can be limited. After that, rotate the moving screw rod 502, and the moving screw rod 502 will drive the fixing plate 501 to move towards the second box body 2, so that the fixing plate 501 can squeeze and fix the second box body 2, further improving the stability when the second box body 2 is connected to the first box body 1.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
