raiser / Bottle openers

The opener that we’re using nowadays limits its use
when we face difficult situations such as people
who has problem with one of their hands or disability people.
This is because, to open a bottle, we have to grab the opener
with one hand and the other hand has to hold a bottle and play a fulcrum role.
The principal of the existing opener is the principal of second class lever
that direction of power and direction of action are same.
I offer a design that we can use it with only one hand that converts
with first class lever which point of action and point of force are affected in opposition.
