Claims17
An apparatus comprising:
- a barrel having a first hole and a second hole opposite to the first hole;
- a first plunger disposed in the first hole,
- wherein the first plunger comprises:
- a body disposed within the barrel and having a diameter larger than a diameter of the first hole;
- and
- a hook member connected to the body and protruding outside the barrel through the first hole,
- wherein the hook member includes an inner spatial area defined by an inner surface of the hook member and a third hole;
- a second plunger disposed in the second hole;
- an elastic connection member disposed within the barrel to connect the first plunger and the second plunger;
- and
- a connection ball in a direct contact with the inner surface of the hook member,
- wherein the connection ball includes a top surface in a direct contact with the inner surface of the hook member, the top surface of the connection ball facing toward the body of the first plunger, and a bottom surface protruding through the third hole of the hook member,
- wherein the inner surface of the hook member covers more than ½ of a surface area of the connection ball, and
- wherein the top surface of the connection ball is positioned outside the barrel.
