[0034] Specifically, when it is necessary to fix the chassis 1, the fixing rod 3 can be embedded in the wall, so as to fix the back panel 11 to the wall, and at the same time, the slider 8 is extended into the slide groove 9, and the fixing block 12 is pushed into the fixing groove 10 by the spring 15, so as to fix the slider 8 to the slide groove 9. Since one side of the slider 8 is fixed on the chassis 1, the chassis 1 can be fixed. When it is necessary to disassemble the chassis 1, the connecting rod 4 can be pulled, and the movement of the connecting rod 4 can be used to drive the two pull rods 14 to move at the same time. The movement of the pull rod 14 drives the fixing block 12 to withdraw from the fixing groove 10 and retract into the installation groove 13. Then the chassis 1 can be lifted to make the slider 8 withdraw from the slide groove 9, so that the staff can disassemble the chassis 1.
