魔域文化 魔方 双调系统 专业比赛竞速顺滑智力玩具 YJ8246

功能介绍：

Function introduction:

传统魔方中心轴由普通螺丝、弹簧、垫片以及中心块和轴组成，缺陷是弹力与轴距不能独立调节，调大弹力将会导致魔方偏紧，影响容错；调小弹力则会导致魔方松散，容易散架。

Traditional core consists of screws, springs, spacers and an axle, but the elasticity and wheelbase can not be adjusted separate.

双调系统则可以做到弹力与轴距独立调节，在不影响魔方松紧，也就是轴距不变的情况下，随意调节弹力大小。

This dual-adjustment system tool can make elasticity and wheelbase adjusted randomly.

双调系统由两级螺丝，弹力调节螺母，双调扳手以及弹簧垫片构成。双调扳手由螺丝调节扳手和螺母调节扳手组合。

Dual-adjustment system tool consists of dual-stage screws, elastic adjusting nuts, dual-adjustment wrench and spacers. Dual-adjustment wrench consists of screw-adjustment wrench and nut-adjustment wrench.

装配方法：

Assembling method:

首先将两级螺丝穿过中心块旋入中心轴，再将垫片弹簧放入中心块，最后用双调扳手将弹力调节螺母装配在两级螺丝的顶端。

Firstly fix the dual-stage screws into the axle through the center pieces, next put spacers into center pieces, then use dual-adjustment wrench assemble the elastic adjusting nuts onto the dual-stage screws.

使用介绍：

Introductions:

首先将双调扳手组合，把螺母调节扳手配合在弹力螺母上，十字刀头插入两级螺丝顶端的十字槽内。单独旋转螺丝调节扳手，将轴距调至合适大小，魔方的松紧完成确认。然后用螺母调节扳手旋转弹力调节螺母，完成魔方弹力大小的调整。在不旋转两级螺丝的时候，魔方的松紧不会发生改变，单独旋转弹力调节螺母，魔方的弹力大小可以随意调节。

Firstly assemble the dual-adjustment wrench, assembling the nut-adjustment wrench and elastic nut. Turning the screw to adjust the wheelbase. Next use nut-adjustment wrench to adjust the nuts, completing the adjustment of elasticity.
