The trapezoidal block 3 compresses the spring 5 through the connecting rod 4. When the trapezoidal block 3 moves to align with the card slot, under the action of the spring 5, the trapezoidal block 3 moves into the card slot to complete the installation of the box body 2, thus reducing the operation of re-drilling holes when replacing the aging box body 2 and improving the work efficiency of the staff. Two slide rails 8 are fixedly connected to the inner side wall of the box body 2. A connecting plate 9 is commonly slidably connected to the surfaces of the two slide rails 8. A round hole is opened on the surface of the connecting plate 9. A fixing bolt 10 movably penetrates through the inner side wall of the round hole. The inner side wall of the round hole is provided with a female thread, and the surface of the fixing bolt 10 is provided with a male thread. A plurality of round grooves adapted to the fixing bolt 10 are opened on the surface of the slide rail 8. Through the slide rails 8, the connecting plate 9 and the fixing bolt 10, when the staff adjusts the connecting plate 9, first rotate the fixing bolt 10. Under the cooperation of the female thread and the male thread, the fixing bolt 10 is separated from the round groove opened on the surface of the slide rail 8 to release the restriction of the fixing bolt 10 on the connecting plate 9. After the connecting plate 9 moves to a suitable position, rotate the fixing bolt 10 in the reverse direction so that the fixing bolt 10 cooperates with the round groove opened on the surface of the slide rail 8 to complete the locking of the connecting plate 9 and complete the adjustment of the distance between the two connecting plates 9, thereby adapting to the sizes of different electrical components and improving the applicability of the device;

[0033] The first step: First, place the box body 2 on the fixing frame 1 and push it, so that the connecting block 7 contacts the inclined surface of the trapezoidal block 3 and generates a downward pressure on the trapezoidal block 3, thereby causing the trapezoidal block 3 to move. The trapezoidal block 3 compresses the spring 5 through the connecting rod 4. When the trapezoidal block 3 moves to align with the card slot, under the action of the spring 5, the trapezoidal block 3 moves into the card slot to complete the installation of the box body 2, thus reducing the operation of re-drilling holes when replacing the aging box body 2;
