[0029] The first pushing part pushes the pulley groups from the outside of the fixed seat 3 and the movable seat 4. When the two pulley groups approach, they clamp the profiled steel block. The way the pulley groups are fixed enables the profiled steel block to move forward and backward, and perform loading and unloading without changing the angle during processing of the profiled steel block, with strong stability.

[0030] When the two pulley groups are retracted, the second pushing part will push the movable seat 4 towards the fixed seat 3 to completely fix the profiled steel block. The two positioning modes can be switched automatically, with high flexibility.

[0031] Regarding the pulley groups:

[0032] The pulley group includes insertion blocks 9 and slots 7 opened at the upper ends of the fixed seat 3 and the movable seat 4.

[0048] The working principle of this application:

[0049] The workpiece to be clamped is placed between the fixed seat 3 and the movable seat 4 at the upper end of the tooling table 1.

[0050] The first pushing part pushes the pulley groups from the outside of the fixed seat 3 and the movable seat 4. When the two pulley groups approach, they clamp the profiled steel block. The fixed manner of the pulley groups enables the profiled steel block to move forward and backward, and perform loading and unloading while keeping the height unchanged. When the two pulley groups are retracted, the second pushing part will push the movable seat 4 towards the fixed seat 3 to completely fix the profiled steel block. The two positioning modes can be switched automatically, with high flexibility.
