For example, the utility model patent with the authorization announcement number CN214291989U proposes a cutting positioning mechanism dedicated to sheet metal, which includes a positioning frame and a plurality of positioning jigs slidably arranged on the positioning frame. The positioning frame includes an inner frame and an outer frame arranged outside the inner frame. Positioning columns are rotatably arranged at the four corners inside the inner frame, and positioning disks for basic positioning of the sheet metal are arranged on the positioning columns. A telescopic column is slidably arranged between the outer frame and the inner frame, and a height-adjusting column for connecting with the positioning jig and adjusting the height of the positioning jig is arranged on the telescopic column.
