| 081900300 | HOSE-CLAMP APPLIERS | 6 |
| 20090064823 | HOSE CLAMP PLIERS - A hose clamp pliers comprises first and second pliers bodies axially combined together by a pivot pillar for forming operating segments and working segments thereon including fitting seats disposed on the front ends thereof for fitting clamping members therein individually, the clamping members including positioning portions for accommodation various types of hose members mounted on one ends thereof, and including shanks with smaller diameters coupled on another ends thereof and inserting through the fitting seats respectively, the inner end surfaces of the positioning portions being biased against the inner end surfaces of the fitting seats respectively, and one ends of the shanks projecting out of the outer end surfaces of the fitting seats, the shanks including holes formed therein for receiving compression springs including balls placed on the free ends thereof and pushed out of the shanks thereby for being retained on the outer end surface of the fitting seats respectively, thus quickly replacing different sizes or shapes of clamping members. | 03-12-2009 |
| 20090199681 | HOSE CLAMP REMOVAL AND INSTALLATION TOOL - A hose clamp compression tool for engaging and compressing opposed or opposite end tangs of a hose clamp includes a first fixed plate and jaw and a second fixed plate spaced from the first fixed plate and jaw. The first and second plates are mounted on rails with a sliding plate and jaw also mounted on the rails and positioned between the fixed plates. The sliding plate is rotatably adjustable in spacing from the one fixed plate by means of a threaded rod journaled to the fixed plates and threaded to the sliding plate. The jaws each include both a transverse slot cooperative with an end tang of a band type hose clamp and a channel extending from the slot for engagement with the end tang of a ring or wire type hose clamp thereby enabling use of the tool for either a band type or a wire type hose clamp. | 08-13-2009 |
| 20100058895 | Hose Clamp Pliers - A pair of hose clamp pliers comprises a pair of universal pliers and two clamping plates. The pliers include two clamping ends capable of moving toward or away from each other. The two clamping plates are fixedly connected to the two clamping ends, and the respective clamping plates are formed with at least one opening. When in use, the two clamping plates are used to clamp the hose clamp, and the universal pliers are used to fix the positions of the two clamping ends, so that the user can position the hose clamp without exerting a continuous force. | 03-11-2010 |
| 20100071514 | TOOL FOR ASSEMBLING AND DISASSEMBLING AND RESILENT COLLAR - According to the invention, the tool for assembling and disassembling an elastic collar includes first ( | 03-25-2010 |
| 20100107823 | Hose Clamp Pliers - A pair of hose clamp pliers comprises a pair of hose clamp pliers and two clamping plates. The pliers include two clamping ends capable of moving toward or away from each other. The two clamping plates are fixedly connected to the two clamping ends, and the respective clamping plates are formed with at least one opening. When in use, the two clamping plates are used to clamp the hose clamp, and the hose clamp pliers are used to fix the positions of the two clamping ends, so that the user can position the hose clamp without exerting a continuous force. | 05-06-2010 |
| 20130228046 | Hose Clamp Pliers - A pair of hose clamp pliers for clamping a hose is provided with two clamping plates. The pliers include two clamping ends capable of moving toward or away from each other. The two clamping plates are fixedly connected to the two clamping ends and provided with movement guide protrusions and movement stop protrusions. With the protrusions formed along the periphery of the two clamping plates and the gaps defined by the protrusions, the hose clamp pliers can clamp the hose clamp in different directions, so that it can be adapted to different work requirements or environments, for example, in a narrow space. Further, the movement guide protrusions and movement stop protrusions restrict the hose clamp in two different directions, so as to improve clamping stability. | 09-05-2013 |
| 20090084227 | ROTARY TOOL - For accurate holding, easy attachment and detachment, and sufficient rotation force, a rotary tool has a holding and transmitting part | 04-02-2009 |
| 20090090221 | Device for Handling Pipes - The invention relates to a device for handling pipes, comprising a clamping device ( | 04-09-2009 |
| 20110000343 | WRENCH WITH RATCHET - A wrench with a ratchet, including: a handle held by a user; and a head coupled to the handle and accommodating and contacting a body to be rotated, wherein the head includes: a base portion connected to one end of the handle; a first jaw extending from a first end of the base portion and including a hanging portion; and a second jaw extending from a second end of the base portion and having a shape corresponding to the first jaw, and wherein a first ratchet member which is adjacent to the hanging portion and of which a portion is moved between an inside and an outside of a rotational path of the body to be rotated that is accommodated in the head. | 01-06-2011 |
| 20120085202 | HEX WRENCH - A hex wrench includes a main body, a handle connected with the main body, a rotary member, a lifting member, a driving member, and a matching member. The rotary member includes an operation portion and a shaft portion. The driving member includes six host driving members and six guest driving members. The matching member includes six matching blocks. The shaft portion passes through the main body. One end of the shaft portion is connected to the operation portion, the other opposite end is connected to the lifting member. One end of each host driving member is rotatably connected with the lifting member, the other end is rotatably connected with a middle portion of a corresponding guest driving member. One end of each guest driving member is rotatably connected with the main body, the other end is rotatably connected to a corresponding matching block. | 04-12-2012 |
| 20120304832 | ELECTRONIC TONG TORQUE SYSTEM AND RELATED METHODS OF USE - Disclosed is an apparatus for attachment to a line pull tong tubing joint make-up system on an oil rig, having tongs attached to two sections of pipe with one tong connected to a line pull apparatus, having a fluid-operated clutch connected to pressurized fluid source and the other tong connected to a piston-cylinder assembly. The apparatus has: a pressure transducer connected to the piston-cylinder assembly to sense the internal pressure in the piston-cylinder assembly and generate an output signal; a valve operable in response to a valve control signal, the valve located in the connection between the clutch and the pressurized fluid source movable between a first position, permitting fluid flow from the fluid source to the clutch and a second position interrupting flow between the fluid source and the clutch; and a controller operably connected to the valve and transducer, programmed to provide a valve control signal to move the valve between the first and second positions in response to the output signal from the pressure transducer, whereby the line pull apparatus is engaged and disengaged. The controller has a display, memory and clock. | 12-06-2012 |
