With the main arm 1 as the center, the two sides respectively have a first auxiliary arm 10 and a second auxiliary arm 11, and after unfolding, a folding arm structure with five sections is formed. Specifically, an articulated seat 3 is fixedly installed on the main arm 1, and the number of the articulated seats 3 is 2. The articulated seats 3 are welded to the main arm 1, and the two articulated seats 3 are axially symmetrically distributed about the central axis of the main arm 1. The end of the drive cylinder 4 is hingedly connected to the articulated seat 3. In this embodiment, a first joint group 6 is installed at both ends of the main arm 1, and the first auxiliary arm 10 is connected to the first connecting seat on the first joint group 6. 61 is hingedly connected, the head end of the driving cylinder 4 is hingedly connected to the hinge 64 on the first joint group 6, and the two ends of the hinge 64 are hingedly connected to the main arm 1 and the first auxiliary arm 10 respectively. The driving cylinder 4 drives the first joint group 6 to deform so that the main arm 1 and the first auxiliary arm 10 are in an expanded state or a folded state. The second joint group 7 is installed on the end of the first auxiliary arm 10 away from the first joint group 6. The end of the pull plate 9 is hingedly connected to the hinge 64 on the first joint group 6, and the head end of the pull plate 9 is hingedly connected to the driving seat 71 on the second joint group 7. The second auxiliary arm 11 is hingedly connected to the second joint group 7. The pull plate 9 drives the second joint group 7 to deform so that the first auxiliary arm 10 and the second auxiliary arm 11 are in an expanded state or a folded state. The folding arm structure is in an expanded state as shown in FIG. Figure 1-Figure 2 As shown, the folding arm structure is in a state where one side is unfolded and the other side is folded.
