It plays a key role in the arm's motion and force transmission, responsible for transmitting power, supporting loads, and ensuring the arm's precise movement. Robotic arm connecting rods come in a variety of shapes, with the most common ones being straight, L-shaped, and U-shaped. Straight rods are suitable for simple linear motion transmission, while L-shaped and U-shaped connecting rods can achieve complex motion trajectories within a limited space.

[0003] For example, a robotic arm connecting rod and a robotic arm thereof are disclosed in Chinese patent publication number CN208196791U. The connecting rod is arranged between two joints of the robotic arm. The connecting rod includes a plate and connecting ends protruding outward into a circle along both ends of the plate. The robotic arm includes a base and a first joint, a first connecting rod, a second joint, a third joint, a fourth joint, a second connecting rod and a fifth joint arranged in sequence on the base.

[0004] However, since the existing assembled robotic arms are large in size, they will occupy a large transportation space during transportation. Common robotic arms will reduce the volume occupied by transportation by folding the robotic arm links. However, during the process of folding the links, some links are too long and the transportation volume cannot be reduced by folding, thereby increasing transportation costs. Utility Model Content

[0023] The following is a detailed description of the specific settings and functions of this embodiment. The No. 3 connecting rod 6 is removed from one end of the No. 2 connecting rod 2, and then the four support bases 4 are installed inside the mounting groove 43 through the fixing bolts 44. The support rod 41 is clamped inside the support base 4, and then the two ends of the No. 3 connecting rod 6 are respectively placed inside the two lower positioning plates 52, so that the two lower positioning plates 52 support the No. 3 connecting rod 6. The upper positioning plate 51 is fixed to one side of the lower positioning plate 52 by rotating the bolts to complete the fixation of the No. 3 connecting rod 6. At this time, when the robotic arm is packaged and transported, the robotic arm will not occupy too much transportation space, thereby reducing transportation costs and facilitating the transportation of the robotic arm in the factory.

[0024] Example 2: Figure 1 and Figure 4 As shown, a combined robotic arm connecting rod that is easy to transport includes a No. 1 connecting rod 1, a No. 2 connecting rod 2 and a rotating base 3.
