A fixed hook 8 is fixedly connected to the outer wall of the rotating shaft 9, and the fixed hook 8 rotates with the rotating shaft 9 as a support point. A limiting hole 7 adapted to the fixed hook 8 is opened on the fixing frame 3.

[0026] Reference Figure 2 , Figure 4 , a door panel is hinged on the top of the toolbox 4, a U-shaped fixing frame 3 is fixed on the side wall, an inner slide plate 10 is slidably installed inside the fixing frame 3, a through hole 12 is provided inside the connecting hole 6 near the side of the fixing frame 3, and the through hole 12 passes through the side wall of the toolbox 4 along the connecting hole 6. A limit rod 15 is protruded on the surface of the inner slide plate 10 facing the toolbox 4, and the limit rod 15 corresponds to the through hole 12. A plug-in block 5 in the connecting hole 6 is provided with a plug hole corresponding to the through hole 12, and the limit rod 15 penetrates the through hole 12 and is assembled and fixed with the plug-in block 5. A through hole 12 is provided inside the inner slide plate 10, and a fixing rod 13 is horizontally fixedly installed on the inner wall of the fixing frame 3, and the fixing rod 13 is slidably assembled with the through hole 12. A spring sleeve 14 is provided on the outside of the fixing rod 13, and one end of the spring sleeve 14 fits the inner slide plate 10, and the other end is fixedly connected to the inner side wall of the fixing frame 3. Pull the inner slide plate 10 gradually away from the tool box 4, the inner slide plate 10 slides along the fixed rod 13, the spring sleeve 14 is squeezed by force, the limiting plug rod 15 moves synchronously with the inner slide rod and retracts into the through hole 12, so that the plug-in block 5 at the bottom of the upper tool box 4 can be inserted and installed.
