But the electric quantity control module is fixed on the upper copper column under the dual action of the pressing force of the pressing device and the supporting force of the upper copper column. In the process, in order to prevent the electric quantity control module from moving, the action point of the pressing device on the electric quantity control module is highly required, so that the operation process is very inconvenient. (2) The upper power-on screw is matched with the upper power-on copper column in a contact and jacking mode by virtue of the pressing force provided by the lower pressing device and the electric quantity control module, and if the acting point is selected to be not in accordance with the requirement, the electric quantity control module is easy to move, so that the upper power-on copper column and the upper power-on screw are in poor contact, and the power-on effect is influenced. (3) Because the front side of the electric quantity control module is close to an operator, and the electrified screw is not beneficial to observation due to the back, the position of the electrified copper column is inconvenient to adjust.

The position relation among the three power-on posts 23 is the same as the position relation among the three power-on screws 1 in the same row on the electric quantity control module 3, so that the power-on posts 23 can be in one-to-one correspondence with the power-on screws 1.
In order to ensure that the upper electric poles 23 are in good conductive contact with the upper electric screw 1, the upper end of each upper electric pole 23 is provided with a tip 24 which can be snapped into a cross-shaped groove in the head of the upper electric screw 1. In other embodiments, the groove of the head of the upper electric screw 1 can also be in a straight line shape, and the shape of the tip of the upper electric screw is in a straight line shape matched with the groove; because the power-on device can stably support the electric quantity control module and reduce the probability of the electric quantity control module moving, the tip can be contacted, pressed and matched with the head of the power-on screw by the plane at the upper end of the power-on column instead of the plane at the upper end of the power-on column.

Of course, the positioning pin and the pin hole can be omitted under the condition that the electric quantity control module is easy to position or other auxiliary positioning measures are provided.
In a second step, the hold-down device 6 is pressed down so that the tip 24 snaps completely into the cross-shaped recess in the head of the upper electrical screw 1, so that the underside of the front half of the power control module 3 rests completely on the upper end face of the support 53.
And thirdly, controlling the electrifying terminal 2 to be electrified and paired so as to electrify the electric quantity control module 3, and then testing or debugging the electric quantity control module 3.
In other embodiments: in order to increase the general performance of the power supply device of the electric quantity control module, the upper power column can be arranged on the terminal body or the bracket in a left-right sliding manner, and at the moment, only a locking piece capable of locking the upper power column after sliding adjustment in place needs to be arranged; the power-on terminal and the bracket can also be movably arranged on the bottom frame, and the power-on terminal and the bracket which are moved in place only need to be locked; the chassis can be omitted, and the power-on terminal and the bracket are placed at proper positions according to the specific size specification of the power control module in the using process; the number of the pillars may be four, five or more, of course, only one or two pillars may be provided, and it is only necessary that the supporting surface of the upper end of at least one pillar is aligned with the upper pillar in the middle in the front-rear direction to form a central supporting portion. That is, only when the supporting surface at the upper end of at least one supporting column is used for supporting the power control module, the acting point of the supporting surface is positioned in the middle of the power control module in the left-right direction; the position relation among the three pillars may not be unique, that is, the distance between the two adjacent pillars may not be equal, and the three pillars may not be in a straight line; of course, the three support posts may be offset from the three upper support posts by a certain distance in the front-rear direction. At this time, no support surface is aligned with the middle upper column in the front-rear direction, and thus the support stability is affected to some extent.
