When the battery is charged, the mounting portion 131 is lifted up, so that the mounting portion 131 moves away from the shielding body 132 until the detecting tube 160 and the charging tube 170 are out of contact with the shielding member 135. At this time, the shielding member 135 is elastically sealed to close one end of the first and second through holes 1322 and 1323 again, so that the corrosion caused by the drop of the electrolyte carried out on the battery can be prevented.

As can be seen from this, when the mounting portion 131 is lifted up after the liquid filling is completed, the shielding body 132 moves toward the side away from the mounting portion 131 by the elastic force of the second elastic member 134, so that the detection tube 160 and the liquid filling tube 170 are retracted into the shielding body 132. When the test tube 160 and the filling tube 170 are completely retracted into the shielding body 132 (it is understood that the test tube 160 is retracted into the second through hole 1323, and the filling tube 170 is retracted into the first through hole 1322), the shielding member 135 loses the pushing force, and is re-engaged with one end of the first through hole 1322 or the second through hole 1323 under the action of the second elastic member 134.

It should be noted that, the connection manner of the second elastic member 134 on the protecting body 132 and the mounting portion 131 may be socket joint, bolt connection, clamping connection, bonding, etc.
