Abstract
The invention discloses a pair of strong locking pipe pliers, which belongs to the technical field of hardware. A handle is provided with a movable jaw which slides freely relative to the handle, and is provided with a force applying lever; the end part of the force applying lever is pressed against the back of the movable jaw; and the force applying lever is used for driving a movable lever to move and clamp a pipe fitting. The pair of strong locking pipe pliers has the advantages of convenience in adjusting and using and stronger clamping force, and is particularly suitable to be applied to installation and maintenance of larger-diameter pipelines.
Description
Technical field
The present invention relates to pipe wrench, relate in particular to a kind of forced locking formula pipe wrench, belong to the hardware ﹠ tools technical field.
Background technology
Pipe wrench is the common tool in the pipeline I﹠M.Existing pipe wrench generally is comprised of pipe wrench handle, regular jaw, moving jaw and adjusting nut, the end of described regular jaw and pipe wrench handle is fixed into one, moving jaw is installed on the pipe wrench handle of regular jaw front end, opening degree between moving jaw and the regular jaw is regulated by adjusting nut, the pipe wrench of this structure exists adjusting cumbersome, jaw is difficult for pipeline is produced enough coupling mechanism forces, thereby not too applicable for connecting between thicker pipeline or the pipeline comparatively closely in the situation.
Summary of the invention
The object of the invention is to: for the existing defects of existing pipe wrench, the invention provides a kind of Novel pipe pliers, overcome the existing existing defects of pipe wrench.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of powerful clamping pipe tongs, it is by handle, application of force lever, bearing pin, active chuck, fixed chuck, regular jaw, moving jaw forms, it is characterized in that: fixed chuck is arranged on an end of handle, fixed chuck and handle all-in-one-piece structure, at handle the active chuck that a relative handle has the relative sliding free degree is set, be shaped with the long slot bore that communicates up and down at handle, be shaped with some adjustment holes with the perpendicular handle in long slot bore two sides, be provided with bearing pin in an adjustment hole therein, in long slot bore, be provided with application of force lever, application of force lever is hinged in the long slot bore of handle actively by bearing pin, the bottom of described application of force lever is resisted against the back position of active chuck, arranges respectively at the interior port part of active chuck and fixed chuck and is fixed with moving jaw and regular jaw.
Beneficial effect: can be found out by structure principle chart of the present invention, the present invention is owing to be forcibly active chuck and fixed chuck to be close together by application of force lever, so, the present invention not only has and regulates and advantage easy to use, simultaneously, also have the comparatively powerful advantage of clamping force, larger-diameter pipeline I﹠M especially suits to be applied to.
