[0020] Specifically, through the deformation and resetting of the shape memory alloy spring 3, the closing and separation between the first T-shaped driving member 1 and the second T-shaped driving member 2 can be realized, thereby achieving the opening and closing effect of the driver, effectively improving the convenience of the driver driving.

[0022] Specifically, the locking bolt 8 facilitates the connection between the shape memory alloy spring 3 and the first T-shaped driving member 1 and the second T-shaped driving member 2 .

[0023] Two fixing grooves 11 are formed on the end surface of the second T-shaped driving member 2 , and two fixing blocks 12 are fixedly disposed at the ends of the terminal posts 6 . The fixing blocks 12 are nested and connected with the fixing grooves 11 .

[0024] U-shaped clamping blocks 10 are provided on both sides of the fixing block 12 , clamping grooves 9 are provided on both sides of the inner wall of the fixing groove 11 , and one end of the U-shaped clamping block 10 is clamped and connected with the clamping groove 9 .

[0025] Grooves 13 are provided on both sides of the fixing block 12 , and the U-shaped block 10 is nested and connected with the grooves 13 . A return spring 14 is fixedly installed on the groove wall of the groove 13 , and one end of the return spring 14 is fixedly connected to the side surface of the U-shaped block 10 .

[0026] Specifically, the expansion and contraction of the U-shaped block 10 is controlled by the return spring 14 , so that the U-shaped block 10 is engaged with and separated from the slot 9 , which facilitates the installation and removal of the terminal 6 .
