In this way, the labor of the workers is saved, and the work efficiency is improved.

[0041] In addition, when the workpiece to be overturned is overturned, the connecting assembly 1 moves along the sliding groove 21 of the rotating arm 2, so that the overturning angle of the workpiece to be overturned is increased.

[0042] Preferably, the connecting assembly 1 comprises a fixing member 11 and a connecting member 12. The fixing member 11 is connected with the workpiece to be overturned, and the connecting member 12 is connected with the fixing member 11 and is slidingly arranged in the sliding groove 21.

[0044] The fixing member 11 can be connected with the workpiece to be overturned by means of adsorption or bolt connection. The fixing member 11 can be a fixing plate arranged on one side of the rotating arm 2.

[0045] Preferably, the fixing member 11 comprises a first fixing part 111 and a second fixing part 112, the first fixing part 111 and the second fixing part 112 are oppositely arranged on the workpiece to be flipped, the rotating arm 2 is arranged between the first fixing part 111 and the second fixing part 112, the first fixing part 111 is provided with a first mounting hole, the second fixing part 112 is provided with a second mounting hole, and the connecting member 12 is arranged in the first mounting hole, the sliding groove 21 and the second mounting hole.

[0046] The first fixing part 111 and the second fixing part 112 are oppositely arranged on both sides of the rotating arm 2 and are connected through the connecting member 12, so that the deformation of the rotating arm 2 caused by excessive force on one side of the rotating arm 2 can be prevented.

[0047] The connecting member 12 is arranged in the first mounting hole of the first fixing part 111, the sliding groove 21 of the rotating arm 2 and the second mounting hole of the second fixing part 112, so that the stability of the connection between the connecting assembly 1 and the rotating arm 2 is improved.
