The first spring 16 is sleeved on the outside of the fastening bolt 25 and applies a force to the first substrate 8 and the second substrate 9 to move away from each other. The fastener 10 can connect the first substrate 8 and the second substrate 9 together, and there is a certain amount of moving space between the first substrate 8 and the second substrate 9 to move closer to each other, so that when the two are subjected to lateral pressure, the first spring 16 can be used to achieve a buffering effect, and it is also convenient to install the circuit board body 1 between the two ridges 3.

[0020] A pushing member 4 for applying an upward thrust to the circuit board body 1 is provided on the bottom plate 5, and a limiting member 7 for limiting the upward movement of the circuit board body 1 is provided on the side frame 2. The pushing member 4 includes a pushing plate 15 and a second spring 14. The pushing plate 15 is located below the circuit board body 1, and both ends of the second spring 14 are in contact with the pushing plate 15 and the bottom plate 5. The second spring 14 applies an upward force to the pushing plate 15. When the circuit board body 1 is vibrated, the compression and rebound of the second spring 14 can play a buffering and shock-absorbing effect.

[0021] A headless bolt 13 for positioning the second spring 14 is provided on the base plate 5. The headless bolt 13 is threadedly connected to the base plate 5.
