[0038] For details, please refer to Figure 1 This is a stereoscopic diagram of a dual coupling sensor provided in an embodiment of the present application, the dual coupling sensor comprises a rotary cylinder 10 and a first joint 20 and a second joint 30 connected to each other in the rotary cylinder 10. By rotating the rotary cylinder 10, the first joint 20 and the second joint 30 are locked.
[0039] See also Figure 2 The rotary drum 10 includes a bottom plate 11 with a clamping hole 111 and a side wall 12 arranged around the edge of the bottom plate 11.
