Description
Technical field
The utility model relates to a kind of hand tools, says it is a kind of Telescopic handle round end pipe wrench in detail.
Background technology
As everyone knows: the round end pipe wrench is connection or the extracting tool that some pipeline operations departments such as oil field, chemical industry, building, geological prospecting often use, and this pipe wrench adopts 3 clampings, and it is more even to distribute, and is difficult for crushing pipe.Generally formed by fixed caliper, moving caliper, jaw and clamping clip handle.Jaw generally adopts weldering, riveting and form such as be threaded is fixed on moving caliper and the fixed caliper.The clamping clip handle then generally all adopts the regular length structure.Jaw is consumable accessory, and during replacing, all there is certain trouble in several types of attachment of above-mentioned jaw and caliper, and jaw can only use fixedly specification, and the clamping diameter range is very little.The clamping clip handle adopts regular length, uses inconvenient under some narrow environments.
Summary of the invention
The purpose of this utility model just is to overcome the deficiencies in the prior art, and a kind of modified round end pipe wrench is provided.
The utility model adopts following technical solution: a kind of round end pipe wrench, be provided with fixed caliper, moving caliper, clamping clip handle, fixed caliper one end and moving caliper are hinged, the other end and clamping clip handle are hinged, be connected with jaw on fixed caliper and the moving caliper, fixed caliper and moving caliper adopt the dovetail mode to connect with jaw, and fixed caliper and moving caliper dovetail groove bottom are provided with nose cone pin and spring, and spring force promotes the nose cone pin jaw is axially locked.The clamping clip handle adopts steel-tube construction, and inner chamber is provided with the extension tongs handle and can moves in the clamping clip handle.Stop nut by being located at clamping clip handle tail end and the locking pin on the extension tongs handle, the maximum length of control pincers handle and the locking on minimum length.Extension tongs handle tail end also is provided with handgrip, with firmly convenient.
The utility model beneficial effect: utilize the dovetail mode to connect the radially big characteristics of bearing capacity, jaw and caliper can adopt flexible lock mode, can change the jaw of different size at any time, have enlarged clamping range.The pincers handle can change length, and adapt under the multiple environment and use, rapid operation, easy to carry.
