In this way, the movable arm 34 or the third pressing arm 41 or the fourth pressing arm 51 can perform the upwarping and down-pressing actions with the connecting rod support arm 6 as the support point. In detail, on the second support 3, the middle part of the movable arm 34 is controlled by the second cylinder 33 to rotate around the connecting rod support arm 6 as the rotating support point, so that the movable arm 34 drives the movable clamping block 32 to rotate to realize the approaching or moving away of the fixed clamping block 31; on the third support 4, the middle part of the third pressing arm 41 is controlled by the third cylinder 42 to rotate around the connecting rod support arm 6 as the rotating support point, and the head end of the third pressing arm 41 realizes the clamping and fixing of the part of the first part; on the fourth support 5, the middle part of the fourth pressing arm 51 is controlled by the fourth cylinder 52 to rotate around the connecting rod support arm 6 as the rotating support point, and the head end of the fourth pressing arm 51 realizes the clamping and fixing of the parts of the first part and the second part.

[0031] The end of the fixed clamping block 31, the end of the movable clamping block 32, the end of the third pressing arm 41, and the end of the fourth pressing arm 51 all have a fork-shaped structure. The fork-shaped structure better realizes the stable pressing and positioning effect of the first part and the second part, so that the side surface of the first part and the second part is more fully contacted.

[0032] The above only describes some embodiments of the present application. Those skilled in the art can make some modifications and improvements without departing from the inventive concept, and these all belong to the protection scope of the present application.
