  • Patent number: 9199363
    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.

    Abstract: A combination wrench includes a shank, a first driving member mounted on a first end of the shank, and a second driving member mounted on a second end of the shank. The shank has different cross-sectional profiles and areas from the first driving member to the second driving member so that the shank has different thickness from the first driving member to the second driving member so as to correspond to different forces. Thus, the mediate portion of the shank has a uniform thickness and has greater strength and torque so as to withstand a larger force so that when a stress is concentrated on the mediate portion of the shank, the mediate portion of the shank can tolerate the stress, thereby preventing the shank from being deformed or broken due to an excessive force.

  • Publication number: 20110094352
    Abstract: One end of a wrench is a first measurement system, such as SAE, and the second end is another measurement system, such as metric, that is close in size to the first end. It is possible to know approximately the correct size wrench needed but not the measurement system. Having two measurement systems in a single tool allows a user to pick a single wrench and have a high probability that one end of the wrench will correctly fit the nut or bolt. The end may be any type of socket, such as open ended or box ended, and the box end may be supplied with a ratchet mechanism. The combination of a first measurement system and a second measurement system on each end, close in size to one another, the ratcheting box end and the ability to reverse the ratchet action direction greatly reduces time and effort in the removal and tightening of bolts and nuts.

  • Patent number: 7926393
    Abstract: A quad wrench has a head including an internal guide, first and second crowns separated by said internal guide, each of said first and second crowns having a plurality of interior faces, and first and second bolt receiving spaces, each bolt receiving space being at least partially defined by an outer surface of said internal guide and some of said plurality of interior faces, and a shank connected to said head. Each bolt receiving space of each crown is configured to correspond to both a first certain size of bolt and a second certain size of bolt such that a bolt of either certain size received in the bolt receiving space can be rotated when force is applied to the shank, and each bolt receiving space of the quad wrench is configured to correspond to two different certain sizes of bolts.

  • Publication number: 20110072940
    Abstract: A wrench includes a handle having an end surface defining a socket and an outer periphery defining a hole in communication with the socket, a wrench head having a body portion inserted in the socket of the handle, and a recess aligned with the hole of the handle, and a fastener detachably fastened to the hole of the handle and having a distal end inserted in the recess of the wrench head. Accordingly, as long as the fastener is removed from the hole of the handle, the wrench head can be drawn out from the socket of the handle for maintenance or replacement.

  • Publication number: 20110005357
    Abstract: A multi-size wrench is defined with an engaging hole in a head thereof, and an inner surface of the engaging hole of the head is formed by six arc-shaped engaging concaves and six arc-shaped connecting convexes which are alternatively connected to each other in such a manner that between each two neighboring engaging concaves is connected a connecting convexes. An angle between the connecting lines from two ends of the respective arc-shaped engaging concaves to the center of the engaging hole is 50 degrees, and an angle between the connecting lines from the center of the engaging hole to a middle connecting point of each arc-shaped connecting convexes and to a connecting end of the connecting convex is 5 degrees. By such arrangements, the multi-size wrench is applicable to a Metric hexagonal fastener, an English hexagonal fastener and a torx fastener which are correspondingly sized.

  • Patent number: 7861621
    Abstract: A driving head of a wrench includes three engaging surfaces and three reception concavities alternatively defined in an inner periphery thereof. A recess is defined in a center of each of engaging surfaces and located between first and second engaging portions. The last reception concavity has one of two insides connected to the second engaging portions next to it, the other insides of the last reception concavity is connected with a third engaging portion. The recesses and the reception concavities are sized to accommodate protrusions of a star-shaped nut. The reception concavity is sized to accommodate one of protrusions of a star-shaped nut. The adjacent first and second engaging portions have a common tangent line and three respective common tangent lines are located on three sides of a hexagonal object. The wrench is able to drive the object in two opposite directions without removing the wrench from the object.

  • Patent number: 7845254
    Abstract: A firefighter pocket tool combines the functional features of several traditional tools (slip groove pliers of the curved jaw type, 6 in 1 screwdriver, spanner wrench, gas shut off tool and a striking tool) onto a shared single structure. The tool comprises a pair of slip groove plier members each having a jaw portion, a joint portion and a handle portion, a pivotal bolt, nut and spring member. Upon the upper rear portion of the pliers' upper jaw's head there is formed a protrusion that forms a striking surface and a hook and claw which can be used as a spanner for rocker lug type and similar fire hose couplings. A gas shut off loop can be used as a guard for fingers when the tool is being used as a striking implement.
