Pin is fixedly arranged above dynamic needle lifting mechanism in pin, and the dynamic pin is fixed on dynamic needle lifting mechanism top；The dynamic pin, which stretches out, determines pin
Top contacts to form the outer pin of entire volume pin with determining pin.
Further, the dynamic needle lifting mechanism is cylinder, and the cylinder end is fixed in volume pin above pin, described dynamic
Pin is fixed on cylinder head.
Further, the dynamic needle lifting mechanism includes rack and pinion, and pin is fixedly arranged above support plate in the volume pin,
The support plate side is fixed with slide, and the sliding block being slidably connected with it is provided with the slide, and the rack is fixed on cunning
On block, the rack and pinion is sequentially connected；The dynamic pin is fixed at the top of rack.
Further, the dynamic pin is arc umbrella, and described to determine pin be warhead shape, described to determine to be provided with and dynamic pin phase at the top of pin
The notch of adaptation, the dynamic pin and the outer pin of volume pin for determining pin formation are in integrally warhead shape.
With the above structure, the utility model makes girth in volume pin variable, is controlled in winding by cylinder, makes volume pin
Girth in as defined in reaching；And in core pulling, girth in volume pin is reduced, reduces the contact area of volume wire surface and membrane with rubbing
Wipe power.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.

In figure：1 is cylinder, and 2 is determine pin, and 3 be pin in volume pin, and 4 is move pin, and 5 be support plate, and 6 be slide, and 7 be sliding block, 8
It is gear for rack, 9
Embodiment
As shown in Figure 1, the lithium-ion-power cell of the utility model winds with pin 3 in volume pin, including volume pin and rolls up outside pin
Pin, the outer pin of the volume pin include determine pin 2 and dynamic pin 4, described determine pin 2 and be fixedly connected on to roll up in pin on the outside of pin 3；In the volume pin
Pin 3 is fixedly arranged above dynamic needle lifting mechanism, and the dynamic pin 4 is fixed on dynamic needle lifting mechanism top；The dynamic pin stretching is determined pin 2 and is pushed up
Portion contacts to form the outer pin of entire volume pin with determining pin 2.
Further, it is cylinder 1 needle lifting mechanism to be moved described in present embodiment, and 1 bottom of cylinder is fixed on volume pin
The interior top of pin 3, the dynamic pin 4 are fixed on the top of cylinder 1.
Further, the dynamic pin 4 is arc umbrella, and described to determine pin 2 be warhead shape, described to determine the top of pin 2 and be provided with and move
The adaptable notch of pin 4, the dynamic pin 4 and the outer pin of volume pin for determining the formation of pin 2 are in integrally warhead shape, and such structure is easy to lithium electricity
Pond is wound.
As shown in figure 3, the Dong Zhen needle liftings mechanism of the utility model can also use the cooperation of rack 8 and gear 9, it is described
Pin 3 is fixedly arranged above support plate 5 in volume pin, and 5 side of support plate is fixed with slide 6, is provided with the slide 6 and is slided with it
The sliding block 7 of dynamic connection, the rack 8 are fixed on sliding block 7, and the rack 8 is sequentially connected with gear 9；The dynamic pin 4 is fixed on
The top of rack 8.So rotated by band moving gear 9, so that moved up and down with carry-over bar 8 and the overall of sliding block 7 in slide 6, from
And realize the lifting action of dynamic pin 4.
Certainly, the utility model can also use screw rod or other applicable dynamic needle lifting mechanisms, move pin 4 and determine 2 shape of pin
