[0024] In the actual operation of the present invention, after the cylinder 6 is started, the telescopic end extends downward, thereby driving the downward pressing fixing block 8 to descend. When the raw material 17 to be processed is placed on the clamping table 1, the raw material 17 can be fixed by pressing down the downward pressing fixing block 8, which facilitates the subsequent processing of the raw material 17 into a tool of a suitable shape.

[0025] The telescopic end extends downward, which drives the slider 7 to move on the slide rail 9, thereby enhancing the stability of the downward and upward pressing of the fixed block 8.
