[0005] In the above technical solution, a more specific solution is: the lifting ring is movably fixed on the lifting ring pin shaft hinged between the first suspension rod and the second suspension rod through a lifting ring mounting buckle.

[0006] Further: the connecting rod is sleeved with two bearings, and a positioning sleeve is installed between the two bearings.

[0007] Further: the bearing is a deep groove ball bearing, model 6203-2RS.

[0008] Further: the cross section of the rotating claw is set in an "L" shape, a threaded hole for fixing to a workpiece is opened on the plane side, and the vertical side is fixedly connected to one end of the connecting rod.

[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0010] 1. The utility model has the advantages of simple structure, high production efficiency, low cost and high safety, and greatly reduces the labor intensity of the operator.

[0011] 2. The utility model is directly used in the wheel hub processing production line. It has low cost, high return and broad market prospects. After being put into use, it has produced certain economic benefits:

[0012] 3. The utility model reduces the equipment purchase cost: the cost of the device is only 200 yuan, while the price of the flipping equipment used for this process on the market is 150,000 yuan, which greatly reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS
