[0025] When the hook 5 is needed, the crossbar 4 on the hook 5 is directly placed in the slot 3, then the handle on the threaded rod 7 is twisted to rotate the threaded rod 7, the threaded rod 7 is in screw transmission connection with the sleeve 6, so that the threaded rod 7 descends and drives the pressing plate 8 to descend in the sleeve 6, the gas in the sleeve 6 enters the guide cavity 18 through the communication cavity 9, and then pushes the sealing plate 12 in sliding connection in the guide cavity 18, the sealing plate 12 pushes out the plug rod 10, and then the plug 11 at the other end of the plug rod 10 is inserted into the insertion slot 13 to limit the crossbar 4.

[0026] The fixing part 1 further comprises a limiting part arranged in the slot 3, and the limiting part comprises a limiting cavity 14 formed in the inner wall of the insertion slot 13.

[0027] A memory alloy 16 is in sliding connection in the limiting cavity 14.

[0028] A stress plate 15 is arranged in the insertion slot 13, and the spring 17 is fixedly installed between the stress plate 15 and the inner wall of the insertion slot 13.

[0029] One end of the memory alloy 16 extends into the insertion slot 13 and is fixedly connected with the stress plate 15.

[0030] The other end of the memory alloy 16 is fixedly connected with a limiting head 19 arranged at the lower side of the spring 17.

[0031] The fixing part 1 and the limiting part are both provided with two groups and are respectively arranged at two ends of the U-shaped ring 2.

[0032] When the plug 11 is inserted into the insertion slot 13, the plug 11 first contacts the stress plate 15 and pushes the stress plate 15, and the other end of the memory alloy 16 is pushed out of the guide cavity 18 through the stress plate 15, the limiting head 19 at the other end of the memory alloy 16 is pushed out, and the plug 11 is secondarily limited, thereby enhancing the fixing effect of the plug 11 inserted into the insertion slot 13.
