10. A method for using an FMS flexible modular system, characterized in that: An FMS flexible modular system according to any one of claims 1 to 9 is used, and the method of using the system comprises the following steps: The first step is to install the required assembly mechanism on the first fixing plate (201), the second fixing plate (202) and the third fixing plate (203); The second step is to place the jig on the top of the frame (803) and limit the moving direction of the jig by blocking the first limiting plate (801) and the second limiting plate (802); In the third step, when the position of the fixture needs to be moved, the swing assembly (4) drives the push assembly (5) to move upward, and the push assembly (5) drives the pulling plate (601) and the pulling rod (602) to move simultaneously. At this time, the pulling rod (602) is inserted into the pulling hole on the fixture, and then the pushing assembly (5) drives the pulling plate (601), the pulling rod (602) and the fixture to move to the desired position; In the fourth step, the pressing plate (702) is driven downward by the pressing block (703) to press, thereby fixing the position of the jig by pressing, and assembling the jig by installing the assembly mechanism.
