2. The connecting part and the holding part are of an integrally formed structure, so that the connecting part and the holding part are easy to machine and form and high in strength, and the clamp of the device is integrally formed by adopting a casting or carbon steel machining, so that the clamp can bear large force when a product needing stress is compressed.

3. The outside end of support extends to the installation department of upwards bending, connecting portion with installation department normal running fit makes the handle is in the rearmost, is difficult for the tong during the operation.

4. The hinge assembly uses the copper sleeve, the rotating medium is the copper sleeve, and the copper sleeve is low in cost and easy to replace.
