[0002] Metal product crimping equipment, product riveting machine, hydraulic pressing machine and other different names, all use external pressure to press the product to the required state. Some products need to be pressed tightly, and some products need to be pressed into place. The specific ones are customized according to product requirements. In actual operation, it is often operated by pneumatic oil pressure, which can accurately control the equipment. This equipment is a riveted structure, which can be used for hand-held and automated riveting, and is very flexible to use. It can be moved within a certain range according to user needs.

[0003] The existing pneumatic riveting joints have poor flexibility during operation and are very troublesome to use in actual operations. After pressing, the staff needs to manually move the button back to its original position, which makes it difficult to achieve automatic reset and is rather cumbersome. For this reason, we propose a pneumatic hydraulic rivet-free riveting structure. Utility Model Content
