Abstract

A tool including a tubular wrench portion and a hollow grasping portion. The tubular wrench portion has a first end, a second end, a hollow body portion located between the first and second ends and a plurality of arc portions located at the first end. The hollow body portion has a first slot extending from the first end to the second end. The arc portions have an outer surface for installing the C-shaped fastening ring thereon to generate torsion and an inner surface formed with a shaped portion to engage with a shaped outer surface of a connector ring. The arc portions are outwardly extended by the torsion when a predetermined torsion is enough to deform the arc portions of the tubular wrench portion.

Claims

1. A tool having a torque limiting function comprising:

a) a hollow grasping portion having a second slot communicating with a hollow interior of the hollow grasping portion;

b) a tubular wrench portion connected to the hollow grasping portion and having;

i) four arc portions equally spaced apart and located on a first end thereof, the four arc portions being movable between first and second positions and providing the torque limiting function, the four arc portions having a C-shaped recess located on an exterior periphery thereof;

ii) a hollow body portion located between the four arc portions and the hollow grasping portion; and

iii) a first slot extending along a length thereof from the first end to a second end of the tubular wrench portion and communicating with a hollow interior of the tubular wrench portion, the first slot communicating with the second slot, opposing ends of the C-shaped recess are spaced apart from the first slot; and

c) a C-shaped fastening ring made of a rigid material and inserted into the C-shaped recess,

wherein, when the four arc portions are located in the first position, the four arc portions are held in a normal position by the C-shaped fastening ring, and, when the four arc portions are located in the second position, the four arc portions are pressing outwardly against and deforming the C-shaped fastening ring.

2. The tool according to claim 1, wherein a movement of the four equally spaced arc portions between the first and the second positions is controlled by a tensile strength of the C-shaped fastening ring.

3. The tool according to claim 1, further comprising a stepped thrusting portion located in the hollow interior of the tubular wrench portion and spaced a predetermined distance from the first end of the tubular wrench portion.

4. The tool according to claim 1, wherein opposing ends of the C-shaped fastening ring are spaced apart from the first slot.
