jar opener

grabcad

The aim of this project to reduce the difficulty to open a jam jar especially for elders. It is very challenging task for anyone. I used here nut and bolt mechanism to open it, here is a cone and a cylinder, cone plays bolt role and cylinder plays a nut role .when you put this set up on a jam jar cap and rotate the cylinder then it apply force on cone ultimately cone bigger diameter got shrink and hold the jar cap very tight after it when you apply more force its transfer the force to the jar cap and it open the jar cap with ease.
