DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4As shown, a lithium battery detection device comprises a box body 1, a hanging ring 17 is provided on one side of the box body 1, at least one first slot 2 is provided on one side of the box body 1, a positive electrode sheet 3 is fixedly connected to one end of the first slot 2, a groove 4 is provided on the box body 1, a detection mechanism 5 is fixedly connected in the groove 4, a power display screen 16 is provided on the detection mechanism 5, second slots 6 are arranged correspondingly on both sides of one side of the box body 1, a plug post 7 is movably inserted in the second slot 6, and an extension box body 8 is fixedly connected to one end of the plug post 7.
