It's a wheel puller.

The difference from traditional wheel pullers is that

The upper part opens up like an alligator's mouth and holds the wheel.

It's supposed to be held.

When removing a wheel that is tightened to the shaft, such as a carbon wheel,

Prevents bending of the grip of the wheel.

It is also designed on the road to the support part of the screw that pulls out the wheel.

Minimize shaking.
