Spring；Probe rod rear end, which is higher by insulating part, is equipped with card slot, and snap ring is connected on card slot.
Further, conductive component include by the rear end of front end be connected in turn the first locking nut on main shaft, gasket,
Waveform elastic part, conductive braided fabric line and the second locking nut.
Further, the insulate rear end of external piece is equipped with fixed leading end, and its rear end end is external connection end, and external connection end passes through
Conducting wire is connect with conductive braided fabric line.
Further, snap ring limitation probe front end exceeds main shaft probe.
Further, syringe needle and probe rod can also be integrally formed eccentric structure.
Utility model works principle and its advantage are as follows：
External connection end is connect with current circuit, is charged by main shaft, and especially by main shaft probe for battery.
Probe is fixed on panel by insulation external piece, and probe rod rear end connection voltage tester circuit is examined by probe
Survey the voltage of battery.
Specifically, under the action of contact, probe end motion backward, at this time probe rod push insulated slide part to
End motion afterwards, then, main shaft probe contact battery, battery charging.
After battery charges electricity, main shaft probe leaves battery, because under normality, probe is exposed on the outside of main shaft, works as master
Axis probe leaves battery, and resetting spring pushes the end motion forward of insulated slide part, so as to which probe rod be pushed to think nose motion, when
When snap ring resists insulating part, probe contact battery, and main shaft probe does not contact, and carries out voltage detecting.
It is worth noting that, when probe and probe rod are designed using split, limiting protrusion can effectively prevent probe
Head comes off because of the effect of resetting spring.
In conclusion the utility model has the following advantages that：
Originally concentric voltage needle is changed to eccentric structure by the utility model, can reduce the shape main body of probe, can
Ensure that end of probe voltage is directed to the test request of battery pole ear, and the structure size requirement of product actual installation can be met
The also advantageous saving product of the utility model uses space, increases utilization rate of equipment and installations, while the utility model is being tied
Structure reasonable design itself carried out voltage probe the design of split type and integral structure, it is ensured that probe meets eccentric
Meanwhile probe rod is vertical.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments：
Embodiment 1：
A kind of eccentric structure voltage probe, as shown in Figures 2 and 3, a kind of eccentric structure voltage probe, including main shaft 1, bullet
