[0032] Working principle: When the flip cover body 1 needs to be opened, the handle 201 is held by hand and moves in an arc with the central axis 205 as the center. The handle 201 can drive the L plate 202 to move. Under the guiding action of the pressing groove 6 on the guide slider 204, the L plate 202 can make the connecting column 203 drive the linkage plate 701 to move. The linkage plate 701 can drive the first guide wheel 702 and the second guide wheel 703 to move. The first guide wheel 702 and the second guide wheel 703 can move under the guiding action of the composite guide groove 1 802 and the composite guide groove 2 803 respectively.

When installing the circuit board, it is only necessary to reverse the above operations to first fold the flip cover body 1 to be parallel to the circuit board, and then use the flip cover body 1 to compact the circuit board, so as to avoid the end of the circuit board close to the folding point of the flip cover body 1 from being crushed. By turning the hand screw bolt 3, the limit of the hand screw bolt 3 on the threaded groove plate 14 can be released, so that the folding bottom plate 13 can be opened. When the folding bottom plate 13 is folded, the telescopic rod 1203 can be extended, so that the folding bottom plate 13 can be opened conveniently, and the detection device or circuit board can be stored inside the folding bottom plate 13.
