Detailed Description

In order that the above-recited objects, features and advantages of the present utility model will be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description. In addition, the embodiments of the present utility model and the features in the embodiments may be combined with each other without collision.

The utility model provides a power battery contact point pole as shown in fig. 1-3, includes battery 1 and contact point pole 2, contact point pole 2 is several style of calligraphy and includes internal thread groove 21 and radian annular 22, the degree of contact annular 22 is located the tip setting of contact point pole 2 towards battery 1, be provided with the protruding 12 that matches with radian annular 22 on the battery 1 roof, still be provided with locking platform 3 on the battery 1 roof, locking platform 3 includes by the protruding base 31 of extension on the battery 1 roof and is located the locking lever 32 that stretches out of relative contact point pole 2 in base 31, still be provided with locking annular 23 on the contact point pole 2 side that locking lever 32 just is right.
