Stand Trolley Case / Trolley Case

Stand Trolley Case
Stand Trolley Case

When taking a bus with a trolley case, the case will move forward because of inertia when the bus suddenly brakes.
In order to solve this problem, we invent the stand trolley case .when you push the handle, press the button to lock the wheel, so the trolley case will stand firmly when the bus brakes. And when you pull the handle ,it will release the button and unlock the wheel, so it can move freely and easily.
