[0031] The above scheme is adopted: when in use, the first cavity block 1 can be inserted into the second cavity block 11, and the second cavity block 11 can play an insulating role. When the cylindrical battery is placed in the first circular hole 12, the clamping assembly will move up and down. When the clamping assembly moves, it can contact with the cylindrical battery.

The lower end of the first pin shaft 2 is fixedly connected with a clamping block 21, and the clamping block 21 is arc-shaped.

[0033] The above scheme is adopted: when in use, when the clamping assembly moves, the first pin shaft 2 will rise or fall in the pin hole 14, and the first pin shaft 2 will drive the clamping block 21 to move while rising or falling. When the clamping block 21 moves to the appropriate position, it will contact with the cylindrical battery. While in contact, the clamping block 21 can clamp and fix the cylindrical battery. The material of the clamping block 21 is rubbery. When in contact with the cylindrical battery, it will not scratch the appearance of the cylindrical battery, and it can also have an anti-slip effect on the cylindrical battery, so that the cylindrical battery is difficult to shake in the clamped state, and the stability of the external output current of the cylindrical battery can be improved, and it will not fall easily.

[0034] See also Figure 2 , Figure 3 and Figure 7 A driving assembly is provided at the right end of the first cavity block 1, and the driving assembly includes a first rotating shaft 3, and a first gear 31 is fixedly connected to the outer surface of the first rotating shaft 3, a threaded rod 32 is provided on one side of the first rotating shaft 3, and the output end of the threaded rod 32 is fixedly connected to one end of the first rotating shaft 3, and a first rack 33 and a second rack 34 are meshed on both sides of the first gear 31, and a first connecting rod 35 and a second connecting rod 36 are respectively provided in the first rack 33 and the second rack 34, and the first connecting rod 35 and the second connecting rod 36 are both inserted into the first pin shaft 2, and the driving assembly is used to drive the clamping assembly to lift and lower.

During the lifting process, the first rack 33 and the second rack 34 can drive the first pin 2 to rise or fall, so that the clamping assembly can be driven to move, and at the same time, the stability of mutual transmission can be improved, and the efficiency of the clamping assembly in clamping the cylindrical battery can be improved.

The exhaust holes 6 are evenly distributed around the axial center of the second circular hole 13 .

[0039] With the above solution, when the cylindrical battery generates heat during use, the heat can be discharged to the outside through the exhaust hole 6, so that the temperature of the cylindrical battery itself will not be too high, and the use efficiency and life of the battery can be improved.

[0044] The working principle of this utility model:

[0045] When in use, the first cavity block 1 can be inserted into the second cavity block 11, and the second cavity block 11 can play an insulating role. When the cylindrical battery is placed in the first circular hole 12, the clamping assembly will move up and down. When the clamping assembly moves, it can contact with the cylindrical battery. The clamping assembly can clamp and fix the cylindrical battery. At the same time, the clamping assembly can be adjusted according to the diameter of the cylindrical battery, so that the cylindrical battery is difficult to shake in the clamped state. At the same time, it can also improve the stability of the external output current of the cylindrical battery and will not fall easily.

[0046] To sum up: the cylindrical battery negative electrode combination cap solves the problem that it is difficult to fix the cylindrical battery through the clamping component, the driving component, and the auxiliary sliding component. When the cylindrical battery is in contact with the cylindrical battery negative electrode combination cap, the cylindrical battery will shake, which can easily cause the cylindrical battery to fall and affect the unstable output current of the cylindrical battery.
