Example Embodiment
[0022] Example 1
[0023] Such as Figure 1-Figure 4 As shown, a shape memory alloy eccentric locking device includes a bolt 1, a connecting piece 31, and a connected piece 32. The bolt 1 passes through the through holes of the connected piece 32 and the connecting piece 31 and then is connected to the locking mechanism. The tightening mechanism includes a memory alloy fastening ring 21, a slotted nut 22 and a locking pad 23. The locking pad 23 is sleeved on the bolt 1. The bottom of the locking pad 23 is in contact with the surface of the connecting piece 31, and the upper portion of the locking pad 23 is a cone. Shaped eccentric connector, the tapered eccentric connector is installed with the bottom of the slotted nut 22, the upper part of the slotted nut 22 is annularly distributed with a number of internally threaded petals, the internally threaded petals are matched with a memory alloy fastening ring 21, and the bottom of the slotted nut 22 is inside With a tapered structur...
