The first clamping member 7 is fixed to the lower end of the fixed connecting plate 4; the second clamping member 8 is fixed to the lower end of the movable connecting plate 5. The disassembly work is placed above the PCB board, with one hand holding the mounting base 1 to prevent the mounting base 1 from moving. The first clamping member 7 and the second clamping member 8 are used to clamp the device on the PCB board. The X-axis adjustment device 6 is used to control the movable connecting plate 5 to move towards the fixed connecting plate 4 until the first clamping member 7 and the second clamping member 8 clamp the device. Then, the Z-axis adjustment device 2 is used to control the lifting slide 3 to move upward, driving the device upward, so that the device is removed from the PCB board. This design can stably disassemble the device without causing damage to the device or the PCB board.

[0016] The mounting base 1 is a U-shaped base with an opening facing downwards, including a top plate 11 and two side plates 12 distributed at the bottom of the top plate 11. The side plates 12 are provided with vertically arranged waist-shaped holes 121. The lifting slide 3 is located between the two side plates 12. The front and rear ends of the lifting slide 3 are respectively equipped with cylindrical pins 31. The cylindrical pin 31 on the front side extends into the waist-shaped hole 121 of the front side plate 12. The cylindrical pin 31 on the rear side extends into the waist-shaped hole 121 of the rear side plate 12. The cylindrical pin 31 cooperates with the waist-shaped hole 121 for guidance and positioning, so as to realize the lifting slide 3 can slide up and down within the mounting base 1.
