Patent attributes
A push button release mechanism for coupling together two portions of a tool, such as pliers. The push button release mechanism can include a push button and one or more balls pushed in a radially-outward direction by geometry of the push button to pivotally couple the two portions together. The balls are normally pushed outward by an engagement portion. Depressing a push button head axially downward causes the balls to align with a receiving portion, which allows the balls to descend into the interior of the mechanism. The push button release mechanism is also threadably coupled with a threaded opening of one of the portions. The threaded opening can have deformed threads to increase the retention torque required to rotate the push button release mechanism.
