It can be understood that the above scheme can be used to improve the fixing effect of the steel component, and can also be used to flip the steel component to facilitate welding at different angles.

[0031] According to this specific embodiment, the support 103 is fixedly connected to the base 101 and is located on one side of the base 101. The movable member 104 is provided on the support 103.
