One end of the screw 21 is provided with a handle, and the screw 21 is rotated by rotating the handle, so that the two sliding parts 22 move back to back or move towards each other, and the distance between the two clamps 1 is driven to be increased or decreased, namely the height between the two clamps 1 is increased or decreased. Because many electronic components are installed on the PCB, the height of each PCB is different, and when two PCBs are fixed on the PCB connecting structure through the clamp 1, the height between the two clamps 1 needs to be adjusted so as to prevent the two PCBs from influencing each other.

The spring group comprises a plurality of springs 14, the plurality of springs 14 are distributed between the upper clamping plate 11 and the lower clamping plate 12 in an array mode, one end of each spring 14 is fixed on the upper clamping plate 11, and the other end of each spring 14 is fixed on the lower clamping plate 12.
