Extending outwardly from the arcuate tool head is a lever member which is designed to receive a handle [selected by the user for appropriate length and torque] for the user to hold and apply the necessary amount of torque to tighten or loosen the hammer union. By receiving the tab in the arcuate head, the user is precluded from damaging the tabs or lugs since no impact is received by the latter and a maximum amount of work can be done safely by the user. Structural features are also provided to prevent improper use of the tool.

  • Publication number: 20140230610
    Abstract: A wrench device includes a first handle and a second handle. The first handle has a pivotal connecting segment and a driving head defined at two ends thereof respectively. The pivotal connecting segment has a groove defined around an outer periphery thereof. The second handle has a pivotal connecting recess and a driving part defined at two ends thereof respectively. The pivotal connecting segment of the first handle is pivotally inserted into the pivotal connecting recess of the second handle. The second handle has a side screwed hole opened on a surface therethrough. The side screwed hole communicates with the pivotal connecting recess and corresponds to the groove. A position member is screwed into the side screwed hole. Therefore, when either the driving head or the driving part is broken, the first handle and the second handle can be separated by unscrewing the position member from the side screwed hole.

  • Patent number: 8695460
    Abstract: A wrench includes a handle having a driving head which has a clamping hole. The driving head has a top surface and a bottom surface. The outer periphery of the top surface is tangent to an inside of a first circle and the outer periphery of the bottom surface is located on a second circle. The first circle is larger than the second circle. The second circle is larger than the clamping hole. When the first and second circles are projected on a horizontal plane, the second circle is located within the first circle and is tangent to the second first circle at a tangent point. The clamping hole and the first circle are located on a common axis which is located on a vertical plane. The two respective centers of the first and second circles and the tangent point are located on the vertical plane.

  • Publication number: 20140090519
    Abstract: This invention relates to an open-ended wrench device, consisting of two pivoting arms diametrically opposed on either side of the open-ended wrench. The open-ended wrench device of the claimed invention can be used in plumbing situations in small, enclosed or obstructed spaces. Specifically, the device can be fitted over a fixture, such as a nut underneath a sink with the pivoting arms in the down position. In order to tighten or loosen the fixture in the enclosed space, the pivoting arms can be raised as much as the space permits in order to allow a user to apply the necessary toque to the wrench. The invention further consists of interchangeable plates which can be removably inserted into a slot of the wrench opening to accommodate fixtures of various sizes and shapes.
