Then, the entire tooling is lifted and the semiconductor stainless steel products are placed in the pickling tank for pickling. After the first pickling is completed, the limit pin is unlocked, and the arm and the connecting plate are rotated and adjusted to achieve the flipping of the posture of the semiconductor stainless steel product. After the adjustment is in place, the limit pin is connected between the arm and the connecting plate to achieve locking, and then the second pickling is performed. Before the second pickling, there is no need to re-clamp, only the posture needs to be adjusted.

[0039] Example 2: A pickling tool for semiconductor stainless steel products (see attached Figure 4 To Attachment Figure 6 ), its structure is similar to that of Example 1, the main difference being that in this embodiment, a push bar 21 is installed on the boom for movement, a driving gear disc 22 is installed on the connecting plate, the driving gear disc is tightly connected with the positioning cover, a plurality of attitude adjustment racks 23 are arranged at intervals along the length direction on the push bar, when the attitude adjustment rack and the driving gear disc are adapted to mesh, the push bar moves to drive the driving gear disc to rotate; a positioning spring 24 is installed between the limit pin and the boom, a push rod 25 is provided on the limit pin, a T-shaped connecting hole 26 is provided on the boom and corresponding to the limit pin, a flange 27 is provided on the limit pin, one end of the connecting hole is connected to a positioning ring 28, the positioning spring abuts between the positioning ring and the flange, and the flange abuts on the transition surface of the T-shaped connecting hole.

The gear is always meshed with the driving rack for transmission. Then, the rotating shaft is rotated by the rotating handle. The rotation of the rotating shaft drives the push bar to move. The push surface abuts against the push rod, and the end of the limit pin is pushed away from the locking hole. In this process, the posture adjustment rack is separated from the driving gear disc. After the end of the limit pin leaves the locking hole, the posture adjustment rack and the driving gear disc are adapted to mesh.
