Abstract
A vehicle O2 sensor wrench attachment is made integral with a safety latch for an air hammer rod. The safety latch comprises a jaw assembly that has a swivel tooth that is manually moved from an open position to allow insertion of the air hammer rod into the mouth. For a working mode using the air hammer to hit the jaw assembly, the tooth is moved to a locked mode. A ball and spring assembly ensures the air hammer rod, having a transverse rod, stays in the locked mode during operation.
Claims10
An 02 sensor wrench having a working end with a socket to mount a nut of an 02 sensor, a shank connecting the working end to a free end, the free end comprising:
- a jaw having a curvature to accept a crossbar of a drive shaft of an air hammer;
- a pivot end extending beyond the jaw away from the free end;
- a tooth assembly pivotably connected to the pivot end by an axle that allows the tooth assembly to rotate from a closed to an open mode;
- said tooth assembly having a locking tooth that can rotate beyond an open mouth end of the jaw away from the free end to lock the crossbar therein;
- said tooth assembly having a latch ball and a spring that urges the latch ball into a face of the pivot end;
- wherein moving the tooth assembly to the open mode allows the crossbar to be placed in the curvature of the jaw;
- and wherein moving the tooth assembly to the closed mode forces the latch ball into a détente on the face of the pivot end, thereby preventing an accidental release of the crossbar from the jaw as the air hammer creates rotational force on the working end.
A wrench having a free end with a jaw assembly, said wrench comprising:
- a working end having an O2 sensor socket with a shank connected to the free end with the jaw assembly;
- said jaw assembly comprising a pivot end extending from the shank beyond a jaw having a curvature to accept a crossbar;
- said jaw assembly having a pivotable base that has a locking tooth;
- said locking tooth locks around the crossbar in a locked mode and is manually movable to an open mode;
- and wherein the locked mode further comprises a détente in the pivot end that receives a spring loaded ball that is mounted in the pivotable base.
An air hammer and wrench combination, the combination comprising:
- an air hammer with a drive shaft;
- a connector at a distal end of the drive shaft, said connector comprising a pair of parallel arms with a transverse crossbar;
- a wrench having a working end and a shank connected to a free end, wherein said working end comprises an O2 sensor socket;
- said free end having an open jaw sized to accept the crossbar;
- said free end having a pivot base extending from a distal edge of the open jaw away from the working end;
- a rotating platform pivotally mounted on the pivot base;
- said rotating platform having a locking tooth extending from a rotating platform edge adjacent the distal end of the open jaw;
- wherein rotating the locking tooth inward in the open jaw locks the crossbar therein;
- wherein rotating the tooth outward away from the jaw releases the crossbar from the open jaw;
- and wherein a latch secures the locking tooth in the locked position.
