The two pliers bodies have two pinching heads, two handles, and two pivotal parts. Each of the pivotal parts has a recess and a pivotal hole. A pivotal element goes through the two pivotal holes. The elastic element is disposed in the two recesses and penetrated by the pivotal element. Both urging ends of the elastic element are on opposite sides of the two recesses to urge sidewalls of the recesses, thereby opening the pliers. A buffer region is designed in each of the recesses for the corresponding urging end. When the opening angle of the pliers is greater than that is supported by the elastic element, at least one urging end of the elastic element releases its urging against the recess sidewall and moves in the buffer region. The pliers become relaxed then. | 01-19-2012 |
| 20120132040 | PIVOTING-LEVER HAND TOOL WITH RESILIENT CLOSED-LOOP HANDLE - A hand tool includes a rigid levers having a handle portions and jaw portions. The levers are pivotably interconnected to allow the jaws to move between an open position and a closed position. The hand tool further includes a resilient handle member having a first end and a second end opposite the first end. The first end of the resilient handle member is joined to the handle portion of the first lever, the second end of the resilient handle member is joined to the handle portion of the second lever. The resilient handle member extends in a substantially U-shaped configuration from the handle portions of the first and second levers. Pivoting of the first and second levers moving the jaws to the closed position causes temporary deformation of said handle member, and resiling of the handle member moves the jaws toward the open position. | 05-31-2012 |

| 20120160065 | HYDRAULIC PRESS UNIT - A hydraulic press unit has a fixed part and a movable part. The movable part is moved relative to the fixed part by a hydraulic piston and is moved back into a starting position by a return spring. In addition, the return motion is actuatable as a function of a predetermined applied pressure by activation of a return valve. A control valve is provided which, in addition to the return valve, opens a hydraulic-medium outlet when in its open state and has a hydraulic-medium inflow side and a hydraulic-medium outflow side. In order to configure the hydraulic press unit, when the return valve opens, the control valve is acted on by the pressure of the returning hydraulic medium on the inflow and outflow sides, the pressure being lower on the inflow side due to throttling. | 06-28-2012 |
| 20140230615 | Hydraulic Press Pliers Power Hand Tool - A hand operated hydraulic press pliers tool is provided comprising an upper stationary handle having a fixed serrated upper jaw portion forming the front end of the stationary handle and a tubular portion forming the rear end of the stationary handle. A serrated lower jaw is pivotally attached to the stationary handle and disposed opposing the upper jaw portion. A hydraulic cylinder assembly is centrally disposed within the upper stationary handle and pivotally attached at one end within the tubular portion of the upper stationary handle near the rear of the handle, and the front end of the cylinder assembly pivotally attached to the lower serrated jaw between the lower jaw pivot handle attachment point and the serrated portion of the jaw. A lower tool handle is pivotally attached to the cylinder assembly yoke that is the front end of the pump assembly. A pivotally attached lower tool handle provides a pump lever disposed to engage a concentrically disposed hydraulic pump assembly within the cylinder assembly wherein depressing the top of the hydraulic pump assembly forces fluid into the cylinder assembly expanding the length of the cylinder assembly when the handles are squeezed together by a user. The longitudinal expansion pivots the lower serrated jaw towards the upper serrated jaw gripping a work piece disposed by a user between the jaws. Repeated cycles of squeezing and releasing the handles of the tool effectuate an incremental closure of the jaws onto a work piece with increasing pressure with each squeezing cycle. | 08-21-2014 |
