Convenient clamping device of integrated circuit board

The utility model relates to the technical field of integrated circuit boards, in particular to a convenient clamping device of an integrated circuit board, which comprises a device body, the device body comprises a clamping frame, two groups of second compression springs are fixedly mounted on two sides of the bottom end of the inner wall of the clamping frame, and the number of each group of second compression springs is two. When a worker installs the circuit board body, the connecting rod is held and pulled outwards, the connecting rod drives the pressing block to contract inwards to drive the first compression spring to be compressed and deformed at the moment, the pressing block does not block the circuit board body any more, and after the circuit board body penetrates through the pressing block, the first compression spring is reset to drive the pressing block to reset, so that the circuit board body is fixed. At the moment, elastic force applied by a second compression spring enables a supporting plat
