Claim:
1. A multifunctional tool comprising: a handle bar, with the handle bar defining a working end; and a tool head connecting to the working end of the handle bar and including a connecting hole extending along a phantom axis and receiving the working end, with the tool head having first and second ends on opposite ends of the phantom axis, with the first end being adjacent to a first jaw and the second end being adjacent to a second jaw respectively, with the first jaw extending away from the phantom axis and along a first phantom line which extends transversely to the phantom axis, with the second jaw facing the first jaw and extending away from the phantom axis and along a second phantom line which extends parallel to the first phantom line and transversely to the phantom axis, with the tool head including a third jaw having a first structure extending away from the phantom axis and along a third phantom line and a second structure extending from the first structure and along a fourth phantom line which extends transversely to the third phantom line, with the tool bead including a first engaging space extending between the first and second jaws and being adjacent to an edge of the first jaw which has first, second, third, and fourth sections disposed one after another along the first phantom line and an edge of the second jaw which has first, second, and third sections disposed one after another along the second phantom line, with the first and second jaws including the respective first sections thereof being adjacent to the phantom axis and facing one another and forming a recess individually, with the first and second jaws including the respective second sections thereof facing one another and forming a flat protrusion individually, with the first and second jaws including the respective third sections thereof facing one another, with the first jaw including the edge thereof having a distal end distal to the phantom axis at a first distance, with the second jaw including the edge thereof having a distal end distal to the phantom axis at a second distance which is shorter than the first distance, with the first engaging space having first, second, and third lengths, with the first length defining a maximum space between the first sections of the respective first and second jaws, with the second length defining a minimum space between the second sections of the respective first and second jaws, with the third length defining a minimum space between the third sections of the respective first and second jaws, with the second length being shorter than the first length, with the third length being longer than the second length but shorter than the first length, with the tool head further including a second engaging space extending between a first surface which is defined on an edge of the second structure of the third jaw and a second surface which faces the first surface, with the second engaging space having a fourth length defining a space between the first and second surfaces, and with the fourth length being not shorter than the third length.
