[0025] Two symmetrical support blocks 20 are slidably installed on the front surface of the backing plate 30. The two support blocks 20 are located outside the two clamping assemblies 50. On the upper surface of the backing plate 30, an L-shaped plate 60 is fixedly installed. On the lower surface of the end of the L-shaped plate 60, a cylinder 70 is slidably installed.

The first lead screw 41 rotates to drive the push plate 43 and the clamping assembly 50 to move along the first lead screw 41 towards the backing plate 30. When the push plate 43 contacts the circuit board, start the second servo motor 55. The second lead screw 56 rotates to drive the clamping plate 58 to move downward until it contacts the circuit board, so that the clamping plate 58 presses the circuit board.
