  • Publication number: 20250001565
    Abstract: Hose clamp pliers include a first plier half, a second plier half, and a pivot member. An inner face of the first jaw portion includes a first longitudinal groove and a second longitudinal groove. Each of the first and second longitudinal grooves include a first section extending from a front end of the first jaw portion and a second section extending at an angle from the first section in a direction away from the second jaw portion. An inner face of the second jaw portion includes a third longitudinal groove and a fourth longitudinal groove. Each of the third and fourth longitudinal grooves include a first section extending from a front end of the second jaw portion and a second section extending at an angle from the first section in a direction away from the first jaw portion.

  • Patent number: 11691249
    Abstract: 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.

  • Publication number: 20200061778
    Abstract: Disclosed are adjustable pliers where the pawl mechanism can be engaged or disengaged to adjust a jaw gap of the pliers. The pawl mechanism can be disengaged either by rotating the handles so as to cause a tab to engage a pocket, and/or by lifting upward on the handles to disengage the pawl teeth from corresponding teeth in a slot of one of the handles. The pliers are therefore advantageous because they do not require a button or lever to adjust the jaw gap, and can therefore be adjusted easily.
