It has the characteristics of a complex system with multiple inputs and multiple outputs and can be found in industrial manufacturing, medical treatment, military, semiconductor manufacturing and other fields. A robotic arm positioning device is a device or system used to determine the position and direction of a robotic arm in space. It uses various sensors and technologies to track the position and posture of the robotic arm in real time to ensure that the robotic arm can accurately perform the intended task. However, the current robotic arm positioning device still has the following shortcomings:

[0003] For example, the patent document with publication number CN219522170U discloses a positioning device for working a robot arm. The positioning device for working a robot arm pulls the pull ring to separate the polygonal segment from the upper buckle plate, and then rotates the lock pin, so that the next buckle plate rotates accordingly, and then the lock pin is inserted back to the original position, the angle between the buckle plates is locked, and the angles of the two transition plates and the clasping plate are adjusted in sequence to make the buckle plates as a whole fit the shape of the robot arm rod, so that the device can hold the cylindrical or polygonal robot arm rod tightly, making the equipment more adaptable, but it is not convenient to disassemble and adjust the structure, and its large size makes it inconvenient to carry and store.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a robot arm positioning device is proposed. Summary of the invention
