By setting the adjustment structure 3, the cleaning brush 309 on the charger can be conveniently adjusted before using the charger to charge the lithium battery. Cleaning and maintaining the metal joints at both ends of the lithium battery can remove dust, oxides and other impurities accumulated on the joint surface, reduce contact resistance, and thus improve the current transmission efficiency between the lithium battery and the charger. A positioning rod 312 is slidably penetrated on the side of the slider 302, and the positioning rod 312 is fixedly connected to the inner wall of the slide rail 301. When the slider 302 moves along the inner wall of the slide rail 301, the positioning rod 312 can guide and position the slider 302, thereby improving the stability of the slider 302 during movement. The cleaning brush 309 is specifically a bristle brush, which has good elasticity and can prevent static electricity, thereby improving the practicality of the cleaning brush 309.

By setting the screw rod 42 to be made of stainless steel, the anti-oxidation performance of the screw rod 42 is improved, thereby increasing the service life of the screw rod 42.

[0034] Detailed description of usage: In the utility model, when the device needs to be used to charge a lithium battery, first place the lithium battery to be charged in the charging compartment 2, and then connect the body 1 to the power supply with the help of the charging interface 6 and the wire, so that the lithium battery can be charged. Before using the charger to charge the lithium battery, the cleaning brush 309 on the charger can be conveniently adjusted to clean and maintain the metal joints at both ends of the lithium battery. The specific steps are: first move the metal joint at one end of the lithium battery to be cleaned to contact with the cleaning brush 309, and then pull the handle 310 with the help of the anti-slip sleeve 311, so that the handle 310 drives the connecting plate 303, and the connecting plate 303 drives the slider 302 to move along the inner wall of the slide rail 301, and at the same time, the connecting plate 303 will drive the connecting plate 304, so that the connecting plate 304 drives the turntable 305 to rotate, and the turntable 305 drives the rotating shaft 307, and the rotating shaft 307 drives the disc 308 and the cleaning brush 309 to rotate. As the person pulls the handle 310 to perform reciprocating motion, the cleaning brush 309 can continuously rotate to clean the metal joint at one end of the lithium battery. When the slider 302 moves along the inner wall of the slide rail 301, the positioning rod 312 can guide and position the slider 302, thereby improving the stability of the slider 302 during movement. In addition, the bristle brush has good elasticity and can prevent static electricity, thereby improving the practicality of the cleaning brush 309. By setting the adjustment structure 3, before using the charger to charge the lithium battery, the cleaning brush 309 on the charger can be easily adjusted to clean and maintain the metal joints at both ends of the lithium battery, which can remove dust, oxides and other impurities accumulated on the surface of the joint, reduce contact resistance, and thus improve the current transmission efficiency between the lithium battery and the charger.

[0035] In the present invention, before using the cleaning brush 309 to clean and maintain the lithium battery, the lithium battery can be clamped and limited by the arc plate 45. The specific steps are: first place the lithium battery between the two arc plates 45, and then rotate the screw rod 42 to drive the limiting plate 43, so that the two limiting plates 43 move towards each other in the limiting position of the guide rod 44. When the limiting plate 43 drives the arc plate 45 to abut against the lithium battery, the fixation of the lithium battery to be cleaned can be completed. When the lithium battery maintenance is completed, the screw rod 42 is rotated in the opposite direction to make the two arc plates 45 move away from the lithium battery at the same time. When the arc plate 45 drives the rubber pad 46 to abut against the lithium battery, the lithium battery to be cleaned can be fixed. After the batteries are separated, the lithium batteries can be taken out. The rubber pad 46 can increase the friction on one side of the arc plate 45, thereby improving the limiting effect of the arc plate 45 on the lithium battery to be cleaned. In addition, by setting the screw rod 42 to be made of stainless steel, the anti-oxidation performance of the screw rod 42 is improved, thereby increasing the service life of the screw rod 42. By setting the auxiliary structure 4, when using the cleaning brush 309 on the charger to clean and maintain the metal joints at both ends of the lithium battery, the lithium battery can be clamped and limited, so that personnel can focus more on the cleaning operation without being distracted by maintaining the position of the battery, thereby improving the cleaning efficiency.
