Abstract
The utility model relates to a multi-function pipe wrench which comprises a jaw and a wrench body. The utility model is characterized in that the movable jaw adopts a sliding engaging mechanism which is composed of a jaw, tooth-shaped cams, an axle pin and a torsion spring. The wrench body is composed of a body and an extension bar. The end of the extension bar is provided with a socket wrench which can be used as a pipe wrench with a short handle by the central part plugged together in use. The integration can be formed into a stressing pipe wrench with a long handle. Therefore, the utility model has the advantages of multifunction, easy regulation, light weight and strong applicability.
Description
The multi-function pipe wrench of the utility model is the modified of present widely used conventional pipe wrench, can conveniently be used in the laying and the finishing work of field produces tubing string and various drill and petroleum extraction tools, surface line, belongs to the general utility tool class.
Present conventional pipe wrench exists weight big, and the card pine relies on jaw spiral adjustment card distance, thereby has shortcomings such as labour intensity is big, efficient is low.
It is many, easy to adjust, in light weight, easy and simple to handle and adapt to strong pipe wrench that the purpose of this utility model provides a kind of function.
Multi-function pipe wrench of the present utility model comprises jaw, caliper.It is characterized in that the slip engaging mechanism that moving jaw, profile of tooth cam, pivot pin, torsion spring are formed; Caliper is made up of main body and extension bar, and the terminal available box spanner of extension bar is removed head, can be plugged on together in the middle of during use, and be linked to be with the lock ball retaining mechanism and to be integral body.When separately using, front clamp body originally can be used as the short handle pipe wrench, can consist of afterburning long tongs when forming integral body.The utility model pipe wrench can reduce pipe wrench series of products at present commonly used, can doublely make general box spanner bar after back caliper (title extension bar) separates and use.
Description of drawings:
Fig. 1 is the sketch of multi-functional pipe wrench of the present utility model;
Fig. 2 is moving jaw and caliper connection state schematic diagram.
Below in conjunction with accompanying drawing the utility model is elaborated.
Multi-function pipe wrench of the present utility model is made up of following:
The forward part of caliper comprises as the main body among Fig. 1-10; Sliding jaw-20; Lid is pressed the cover plate-101 of lock ball; The screw of barrier flaps-102; The taper contract bars-103 of restriction jaw block teeth position etc., sliding jaw-20 is main with housing-20 and be fixed on compositions such as handle-24 centre and that have teeth.Boost pipe tongs (-30 are extension bar among Fig. 1) can be formed with the forward part grafting (by the locking of lock ball mechanism) of caliper in the rear section of caliper (extension bar).If lock ball was loosening when cover plate was moved to right-hand member, desirable lower clamp rear section (extension bar), and can be used as the box spanner bar, the forward part of caliper can be done the pipe wrench use in little moment of torsion, little caliber, little space simultaneously.
Press the handle-24 of lower slider engaging mechanism, moving jaw just can unclamp the object of clamping, so can make card apart from enlarging or dwindling along caliper slip moving jaw.
By as seen above-mentioned, the utlity model has multi-functionally, easy to operate, adjust flexibly, promptly can separately use, also available being plugged on together used, and be in light weight, easy to carry, adaptability is strong.
