First grabbing device hole (8a) of grabbing device (2) and described first internal diameter in the second grabbing device hole (8b) are substantially equal to the first negative electrode hook assembly hole (9a) of negative electrode hook assembly (1) and described second internal diameter in the second negative electrode hook assembly hole (9b);

This structure is also furnished with sleeve alignment member (10), each sleeve alignment member (10) all has collar portion (11) and cylindrical shape part (12), and the external diameter of cylindrical shape part (12) is substantially equal to described first internal diameter and is substantially equal to described second internal diameter;

Negative electrode hook assembly (1) is aimed at grabbing device (2), this kind is aligned by as under type realizes: the first sleeve alignment member (10) inserted in the first grabbing device hole (8a) of grabbing device (2) and the first negative electrode hook assembly hole (9a) of negative electrode hook assembly (1), makes the first sleeve alignment member (10) at least enter the first grabbing device hole (8a) of grabbing device (2) and the first negative electrode hook assembly hole (9a) of negative electrode hook assembly (1) in local; Second alignment member (10) is inserted in the second grabbing device hole (8b) of grabbing device (2) and the second negative electrode hook assembly hole (9b) of negative electrode hook assembly (1), make the second sleeve alignment member (10) at least enter the second grabbing device hole (8b) of grabbing device (2) and the second negative electrode hook assembly hole (9b) of negative electrode hook assembly (1) in local; Thus negative electrode hook assembly (1) is aimed at grabbing device (2).

7. structure according to claim 6, is characterized in that:

The cylindrical shape part (12) of sleeve alignment member (10) configures porose, and this hole has the negative thread (13) cooperatively interacted with bolt (14);

One bolt (14) is screwed and is tightened in the negative thread (13) of the cylindrical shape part (12) of the first sleeve alignment member (10), to be fastened on grabbing device (2) releasedly by negative electrode hook assembly (1);

One bolt (14) is screwed and is tightened in the negative thread (13) of the cylindrical shape part (12) of the second sleeve alignment member (10), to be fastened to releasedly on grabbing device (2) by negative electrode hook assembly (1).

8., according to the structure of claim 6 or 7, it is characterized in that:

Grabbing device (2) is configured with the 3rd hole (16);

Negative electrode hook assembly (1) is configured with the 4th hole (17);

The position being configured with described 3rd hole (16) and the 4th hole (17) meets the following conditions: if negative electrode hook assembly (1) is aimed at grabbing device (2) by sleeve alignment member (10), so, at least one the 3rd hole (16) of grabbing device (2) is aimed at at least one the 4th hole (17) of negative electrode hook assembly (1);

Bolt (14) is inserted in one the 3rd hole (16) aimed at one the 4th hole (17).

9., according to the structure of the arbitrary claim in claim 6 to 8, it is characterized in that:

At least one pair of first grabbing device hole (8a) on grabbing device (2) and the second grabbing device hole (8b) are configured by machining mode;
