[0024] Step S4: Loosen the insulation board: Turn the four first bolts on each device counterclockwise. The first bolts move upwards through the first T-block to drive the slider upwards, and the slider drives the pressure plate upwards to release the vertical fixation of the insulation board; at the same time, the upward movement of the slider drives the piston rod and the piston plate upwards, pumping the gas in the first air pressure chamber back to the second air pressure chamber.

[0028] 2. In the present invention, the downward movement of the second bolt drives the cross top plate to move downward, and the downward movement of the cross top plate pushes the cross block upward. The cross block is continuously pushed up, reducing the friction between the device and the insulation board, making it easier for the staff to take the device out from between the insulation boards.

[0029] 3.
