At the same time, the push rod 95 pushes the insertion block 94 to move horizontally. The insertion block 94 will drive the slide rod 92 to move horizontally. At the same time, the insertion block 94 can squeeze the second spring 93. When the magnetic block 96 is attracted to the magnet 97, the insertion block 94 will separate from the pressure base 11. Then the connecting block 91 can be pulled out from the inside of the pressure base 11, and the pressure block 12 can be disassembled.
