[0002] The emergence of robotic arm equipment can replace heavy labor, realize mechanization and automation of production, and can operate in harmful environments, thus protecting personal safety. Therefore, the scope of use of robotic arms is gradually expanding in life, especially in some repetitive grasping work. There are at least the following disadvantages in the use of existing robotic arms: 1. When the existing grasping robotic arms encounter objects with smooth surfaces during use, it is easy to have unstable grasping, so it is necessary to improve the grasping function of traditional robotic arms; 2. The existing robotic arms need to be disassembled during transportation to facilitate subsequent packaging, but users need to assemble them by themselves, which increases the difficulty of use for customers. Therefore, we have launched a new practical robotic arm device. Utility Model Content
