Then the staff will select the appropriate position and height according to the parts and processes to be processed. Then the staff can adjust the required width by sliding the width adjustment rod 4 in the adjusting cylinder 5. When the width is appropriate, rotate the width fixing block 7 so that the width fixing block 7 is close to the adjusting cylinder 5 and in force contact with the surface of the adjusting cylinder 5, and fix the width adjustment rod 4 in the adjusting cylinder 5. After the width is fixed, the staff will select the appropriate processing height by sliding the height adjustment rod 6 in the adjusting cylinder 5.
