Utility Tool for Truck

A utility tool for truck, comprising:

• a handle bar comprising a tubular handle having an axial receiving channel defined therein and an elongated solid bar having a length longer than that of said tubular handle and a diameter slightly smaller than a diameter of said receiving channel;
• a hook element integrally provided at a distal end of said solid bar of said handle bar;
• a thumper head comprising a hammer portion configured to function as a hammer and a glass breaker portion configured to function as a glass breaker, wherein a proximal end of said tubular handle of said handle bar is firmly and securely connected to a position between said hammer portion and said glass breaker portion such that said handle bar is perpendicularly extended from said thumper head;
• and
• a retractor joint assembly configured to rigidly and securely connect said tubular handle and said solid bar in an extendable and retractable manner, wherein when said solid bar is extended form said tubular handle of said handle bar in an extend state, said utility tool is capable of functioning as a fifth wheel pin puller, and that when said solid bar is retracted in said tubular handle in a retract state, said solid bar is ensured to be coaxially received in said receiving channel in a rigid and firm manner to form an ergonomic handle while said utility tool is used as a tire thumper with said hammer portion and a glass breaker with said glass breaker portion of said thumper head, wherein during the extend state, said connector member, said connecting end of said solid bar and said sliding stud together provide an overlapping length to strengthen a connection of said tubular handle and said solid bar and ensure an alignment of said tubular handle and said solid bar coaxially.
