[0028] As Figure 5 Shown, coupling 4 includes light rod bolt 4-1 and nut 4-2. Among them, the tail of light rod bolt 4-1 is processed with snap spring mounting hole, is used to insert snap spring 5. Nut 4-2 is used to prevent clamping plate 1 and tapered sleeve 2 from moving left and right during test.

[0029] As Figure 6 Shown, snap spring 5 is used to insert the snap spring mounting hole of light rod bolt 4-1 after the whole detection device is assembled, prevents nut 4-2 from falling off.
