The depth of the curved chute portion at the bottommost portion of the connector chute 24 is higher than that of the straight chute portion, and the depth of the curved chute gradually decreases to be the same as the depth of the upper end of the straight chute portion. The outer diameter of the connector top column 22 is slightly smaller than the inner diameter of the tapered end secondary cavity 12; the outer diameter of the main column 23 of the connector is larger than the inner diameter of the secondary cavity 12 of the lock head and smaller than the inner diameter of the lock seat 3; the outer diameter of the lock seat 3 is smaller than the inner diameter of the lock cavity 13; the inner diameter of the lock main cavity 11 is equal to the inner diameter of the lock runner 14.

Further optimize the scheme, cavity in the lock seat 3, connector principal post 23 are located lock seat 3, and the bottom of lock seat 3 is equipped with lock seat kerve 33, and the top rigid coupling of lock seat kerve 33 has the one end of lock seat spring 32, and the other end and the connector sill 25 butt of lock seat spring 32, top one side rigid coupling in the lock seat 3 have round pin 31, round pin 31 and connector spout 24 sliding connection.

When the round pin 31 moves to the top end of the connector sliding groove 24, the round pin 31 returns to the bottom end of the connector sliding groove 24 along the connector sliding groove 24 under the elastic force action of the round pin 32 when the round pin 32 is continuously compressed in the process that the round pin 31 moves in the connector sliding groove 24.

When the battery pack 5 is disassembled from the battery bin 41, the round pin 31 continues to move upwards along the connector sliding groove 24, the connector chuck 21 rotates 180 degrees again, at the moment, the connector chuck 21 rotates to the lock head sliding groove 14, and then slides downwards along the lock head sliding groove 14, so that the lock head 1 is separated from the connector 2.
