Quickly shifting / Spanner

Quickly shifting
Quickly shifting

When using traditional shifting spanner, we have to turn the wheel to adjust its jaw to fit the size of the bolt, after the bolt is fit, we can take our hands off. Quickly-shifting spanner makes this using method much simpler. Turning the rolling wheel at the front of the Quickly-shifting spanner, we can directly exert a force without moving our hands. What’s more, it is wrapped by the rubber, which makes it comfortable to use.
