Preferably, a positioning tube is further provided between the linkage sliding rod and the return spring. The positioning tube limits the stroke of the linkage slide rod so that the pole group will not be too tight.

Preferably, the locking mechanism includes a telescopic rod and an operating part, the operating part is connected to the telescopic rod, the comb-shaped fixing frame is provided with 4 positioning parts, and the telescopic rod is fastened to the 4 positioning parts . The structure is simple, the operation of locking and dismounting is convenient, and the cost is low.

Preferably, two sides of the bottom box are provided with magnets, and the comb-shaped clamp is an iron comb-shaped clamp. It makes the installation and positioning of the comb fixture more convenient.

Beneficial effects of the utility model: the utility model can realize the overall welding and slotting of the pole group, simplifies the operation, and also provides tooling support for the realization of the busbar direct connection welding technology or the pre-casting overall bridge technology . It is of great significance to the improvement of the production process of the whole lead-acid battery.

The features and advantages of the utility model will be described in detail through embodiments in conjunction with the accompanying drawings.
