Abstract: A crimping tool is provided including a rotary drive unit and removable extension arm with pivotal jaw arms. The removable extension arm is rotatable about its axis. A locking device is included in the jaw arm assembly such that the jaw arms may be securely positioned in a number of locations to accommodate various working angles. A logic circuit limits the movement of the jaw arms to one complete cycle for each trigger event.

Abstract: A pair of pliers for connecting a telephone line connector. The pliers have a compression connecting block connected with a limiting pin inserted in a limiting hole preferably of a triangular shape on one handle of the pliers. The upper edge of the limiting hole has an abutting edge bevel relative to a push guiding edge of the limiting hole. When the abutting edge contacts and presses the limiting pin, the contact point therebetween is located next to the center of the limiting pin towards the direction of an action force such that the component force of a resisting force from the center of the limiting pin towards the contact point is at the same side as that of the action force. Thus, the horizontal component force of the action force can be reduced; and the abrasion that the horizontal force component may cause on the guiding groove can be reduced.

Abstract: This invention provides an improved crimp tool. The improved crimp tool includes a fixed jaw assembly consisting of two connected halves and a chamber therebetween, wherein one end of the fixed jaw assembly is a fixed jaw and the other end is a first handle, a movable jaw assembly positioned in the chamber, wherein the movable jaw assembly comprises a movable jaw pivotally mounted thereon; a second handle having one end pivotally connected to the movable jaw assembly; a connecting rod positioned in the chamber and the connecting rod having one end pivotally connecting to the second handle and the other end connecting to the fixed jaw assembly; and a ratchet mechanism installed between the fixed jaw assembly and the second handle.

Abstract: The present invention relates to hand operable pliers (1) including a pliers head (2) and a drive (3). The pliers head (2) includes a frame (4), a stationary jaw (7) and a movable jaw (8), and it is designed and arranged to be replaceable. The drive (3) includes two handles (21, 22) and a common joint (20) being designed and arranged to connect the handles (21, 22) to be pivotable about the common joint (20) and to allow for an opening movement and for a closing movement of the handles (21, 22). The common joint (20) forms a pressure bolt (23). The movable jaw (8) is designed and arranged to be detachably supported at the pressure bolt (23). The drive (3) further includes a plurality of connecting members (36) each being designed and arranged to be detachable, two pulling elements (30) being associated with the drive (3) and each having a first end (32) facing the pliers head (4) and a second end facing the handles (21, 22).

Abstract: A fiber optic cable trough notching system with a punch and a punch aperture spaced apart by a wall receiving opening for receiving a fiber optic cable trough component wall, the punch disposed to impart a force on the trough component wall to deform it into the punch aperture, and thereby create a detent and/or projection. The detent and/or projection are then utilized to operatively attach two trough components.

Abstract: A device for cleaning-and-restoring threads of a threaded article for more easily and efficiently cleaning and restoring threads of various sized threaded article. The device for cleaning and restoring threads of a threaded article includes a pliers comprising a handle having a first arm and a second arm pivotally coupled to the first arm. The pliers also include a pair of jaws. Each of the jaws is formed on one of the second ends of each of the arms. A pair of jaw extensions is provided for gripping, cleaning and reforming the threads of a threaded article. Each of the jaw extensions is coupled to and extending away from one of the jaws. Each of the jaw extensions includes an inner surface which are in an opposed relationship to each other. A plurality of teeth is provided for engaging the threads of the threaded article. Each of the teeth is attached to the inner surface of each of the jaw extensions.

Abstract: A cutting tool includes two handles coupled to two cutter blades for forcing the cutter blades to cut the objects. Two or more poles are secured to the handles and extended outward beyond the handles for wire-bending purposes. One of the cutter blades includes a number of teeth and has a lever. A pawl is pivotally secured to one handle and biased to engage with the teeth. An actuator bar is pivotally secured to the other handle and has a post slidably received in the lever for selectively engaging with the lever to force the cutting edges to cut the object.

Abstract: Pliers for crimping work pieces include a first stationary handle (1) and a second movable handle (2). The first and second handle (1, 2) are designed and arranged to be movable with respect to one another and to be operable by one hand. A first pivot jaw (3) is connected to the first stationary handle (1) to form a stationary pliers portion. A second pivot (4) jaw is connected to the second movable handle (2). The first and second pivot jaw (3,4) each includes at least two parallel plates (43, 33; 45, 46) extending symmetrically to a plane of main extension (19) of the pliers. A common joint (5) pivotally connects the stationary pliers portion to the second pivot jaw (4). A first die (32) is designed as a semi shell (34) and to be insertable into the first pivot jaw (3). A second die (33) is designed as a semi shell (35) and to be insertable into the second pivot jaw (4).

Abstract: The J-channel siding tool is preferably used to cut tabs or notches or a miter finishing cut in J-channel vinyl or aluminum siding in perpendicularly adjacent pieces proximate to the corners of doors or windows of a building, through the one cut operation of the tool by an individual. The J-channel siding cutter includes a pair of pivotally interconnected handles, a first cutter having a pair of first cutting surfaces and a first traverse cutting surface on one of the handles, and a second cutter having a pair of second cutting surfaces and a second traverse cutting surface on the other handle. The second traverse cutting surface is recessed with respect to the first traverse cutting surface to enable an individual to selectively determine, in one cut, whether to create a tab or notch within J-channel siding. The first cutter may also include a stop for defining a uniform length of tab or notch.

Abstract: A tool designed to perform the crimping of irregular shaped rings onto surfaces that are also potentially geometrically irregular. Because of the irregular shape of the crimping ring, special holding mechanisms and unique crimping ribs must be employed. A primary use of the subject invention is to field crimp a chain ring onto a cap chain utilized with installed fire hydrant caps.
