At the same time, the fixed block 8 installed at the bottom of the support rod 13 moves upward to move the fixed rod 19 out of the socket 9. At this time, the mounting block 4 is pulled to adjust the position of the mounting block 4. A spring 18 is sleeved on the support rod 13. Since the spring 18 is squeezed when the fixed block 8 moves upward, the spring 18 deforms and generates elastic force. When the pull plate 12 is cancelled, the spring 18 rebounds, driving the fixed rod 19 at one end of the fixed block 8 to move downward, and one end of the fixed rod 19 enters the socket 9 to fix the mounting block 4, so as to flexibly adjust the installation position of different electrical appliances.

[0029] like Figure 1-3 As shown, a fixing column 16 is fixedly installed at the bottom of the guide block 14, one end of the fixing column 16 is fixedly connected to the support plate 17, a spring 18 is located between the support plate 17 and the fixing block 8, one end of the spring 18 is fixedly connected to the support plate 17, a connecting rod 10 is fixedly installed on the bottom plate 5, one end of the connecting rod 10 is fixedly connected to the mounting plate 3, a sealing door 2 is hinged on one side of the box body 1, and a handrail 7 is fixedly installed on one side of the mounting block 4 to facilitate pulling the mounting block 4.

[0030] Working principle: When the position of the mounting block 4 needs to be adjusted, the pull plate 12 is pulled upward, and the pull plate 12 drives the support rod 13 to move in the guide groove 11. At the same time, the fixed block 8 installed at the bottom of the support rod 13 moves upward to move the fixed rod 19 out of the socket 9. At this time, the mounting block 4 is pulled to adjust the position of the mounting block 4. Since the fixed block 8 squeezes the spring 18 when it moves upward, the spring 18 deforms and generates elastic force. When the pull plate 12 is cancelled, the spring 18 rebounds and drives the fixed rod 19 at one end of the fixed block 8 to move downward. One end of the fixed rod 19 enters the socket 9 to fix the mounting block 4, thereby realizing flexible adjustment of the device installation position, improving the internal space utilization of the box, and avoiding device crowding and line extrusion.
