The handle 6 facilitates the operation of pulling out and pushing in the drawer 4, and the power display 7 is used to display the power supply status, so that the user can understand the power supply status of the drawer 4. The arrangement of the wiring compartment 201 facilitates the wiring of external wires and improves the neatness of the power distribution cabinet. The circuit breaker 403 is used to control the circuit between the external line and the electrical components in the drawer 4 to realize the on-off control of the circuit. The incoming plug 401 and the outgoing plug 402 are respectively connected to 206 and 207 to realize the electrical connection between the drawer 4 and the cabinet 2. The ventilation hood 3 is arranged on the top of the power distribution cabinet for Ventilation and heat dissipation ensure that the electrical components inside the distribution cabinet are working normally. A fixing component is provided on one side of multiple drawers 4. The fixing component is used to fix the drawer 4 and the cabinet 2 when power is on to prevent the erroneous operation of pulling the drawer 4 out of the cabinet 2 when the power is not disconnected. A limiting component is provided on one side of multiple drawers 4. The limiting component is used to further limit and fix the drawer 4 and the cabinet 2 to prevent the incoming plug 401 and the outgoing plug 402 from loosening the connection with the corresponding incoming socket 206 and the outgoing socket 207, resulting in a short circuit.

[0040] Two second sliding blocks 404 are symmetrically fixedly connected to the bottom of the drawer 4, and two second sliding grooves corresponding to the two second sliding blocks 404 are opened on the bottom inner wall of the cabinet 2. The two second sliding blocks 404 are slidably connected to the corresponding second sliding grooves.

[0041] The fixing assembly mainly includes an electric lock 8 and an iron sheet 202. The electric lock 8 is fixedly arranged on one side of the drawer 4, and the iron sheet 202 is fixedly connected to the inner wall of the cabinet 2 near the electric lock 8.
