Specifically, when the pulling member 212 is a memory wire, the memory wire is energized by the driving member 211, and the memory wire contracts due to deformation to generate a contraction force acting on the second elastic member 214, so that the force is exerted on the second base 2331 by the second elastic member 214. The second base 2331 and the limiting member 231 may be connected as a whole by a fixing member. Therefore, when the memory metal wire contracts due to deformation, the limiting member 231 is driven to move along the direction of the memory metal wire so as to make the limiting assembly in an unlocking state, after the memory metal wire is powered off, the metal wire recovers to the original length, the limiting member moves towards the limiting groove under the action of the elastic restoring force of the third elastic member 215 so as to make the limiting assembly in a locking state, wherein the second elastic member 214 and the third elastic member 215 can be springs, and the elastic coefficient of the second elastic member 214 is assumed to be K _B The elastic coefficient of the third elastic member 215 is K _F The memory wire is electrically movable towards the driving member 211 by a displacement Δ x ₂ The displacement of the limiting member 231 toward the driving member 211 is Δ x ₁ It has the following relationship:

the limiting member 231 can be moved by a displacement Δ x ₁ <Shrinkage Δ x of memory wire ₂ . To satisfy the moving displacement Δ x of the position limiting member 231 ₁ Run, Δ x ₁ And Δ x ₂ The closer the values are, the less loss occurs by the amount of contraction of the memory wire, and the loss = Δ x2- Δ x1. Therefore, under the condition of limited space of the whole machine, the elastic coefficient K of the second elastic member 214 _B Is much larger than the elastic coefficient K of the third elastic member 215 _F The memory wire shrinkage loss can be close to 0.

When the friction force between the limiting part and the limiting groove is large due to some indefinite factors, the pulling force of the memory metal wire to the limiting part is smaller than the friction force between the limiting part and the limiting groove, and the limiting part and the limiting groove are clamped, the memory metal wire is only compressed even if being electrified, and the second elastic part provides the displacement of the memory metal wire, so that the memory metal wire is protected.
