Abstract

The utility model discloses a dual-purpose spanner wrench which is a hardware tool and is mainly used for tightly screwing or loosening objects, such as screw bolts, nuts, etc. The utility model is mainly composed of a handle body, a fixing wrench body which is connected with the handle body into an integrative body, a movable wrench body and regulating screws. The utility model is characterized in that the handle body is provided with a chain; one end of the chain is connected to the handle body; the other end of the chain can be hung on a hook which is arranged on the handle body. The utility model has the advantage that a traditional spanner wrench which is provided with the chain can be used for both clamping workpieces with symmetrical polygon cross sections, such as screw bolts, nuts, etc., and clamping circular workpieces, such as tubes, etc. The using range of the traditional spanner wrench is widened.

Description

Difunctional adjustable wrench

Technical field

The utility model relates to the adjustable wrench in the hardware ﹠ tools.

Background technology

Adjustable wrench is a kind of hardware ﹠ tools commonly used, and fixed caliper that adjustable wrench mainly is connected as a single entity by handle body, with handle body and moving caliper and adjusting screw(rod) are formed; Adjustable wrench is mainly used to tighten or unclamps objects such as bolt, nut, and function ratio is more single.

Summary of the invention

The utility model will provide a kind of bifunctional adjustable wrench that has.

The technical solution adopted in the utility model is: described difunctional adjustable wrench, and mainly fixed caliper that is connected as a single entity by handle body, with handle body and moving caliper and adjusting screw(rod) are formed; Be characterized in: on handle body, also be provided with chain; One end of chain is connected on the handle body, and the other end of chain can be articulated on the hook, and hook is arranged on the handle body.

The further technical scheme of the utility model is: the top of the fixed caliper on handle body also is provided with anti-skidding line.

The utility model has the advantages that: on adjustable wrench, be provided with chain, make adjustable wrench have the function of chain wrench, widened its scope of application greatly.

Description of drawings

Fig. 1 is the structural representation of difunctional adjustable wrench described in the utility model;

Fig. 2 is that A among Fig. 1 is to the partial structurtes schematic diagram;

Fig. 3 is that B among Fig. 1 is to the partial structurtes schematic diagram.

Embodiment

Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and using method thereof are further described.

As Fig. 1, Fig. 2, shown in Figure 3, difunctional adjustable wrench described in the utility model, mainly fixed caliper 5 that is connected as a single entity by handle body 1, with handle body 1 and moving caliper 4 and adjusting screw(rod) 2 are formed; Be characterized in: on handle body 1, also be provided with chain 8; One end of chain 8 is hinged on the handle body 1 by pin 10, and the other end of chain 8 can be articulated on the hook 3 by its bearing pin 9, and hook 3 is arranged on the handle body 1.In the present embodiment, the top of the fixed caliper on handle body 15 also is provided with anti-skidding line 6.The purpose that anti-skidding line 6 is set is to prevent that pipe 7 from skidding.

The using method of the adjustable wrench of said structure is: when not using chain 8 to come the grip tube period of the day from 11 p.m. to 1 a.m, its using method is identical with traditional adjustable wrench, repeats no more.When using chain 8, needs come the grip tube period of the day from 11 p.m. to 1 a.m, at first the on-fixed end of chain 8 is walked around pipe 7, chain 8 tightly is looped around on the pipe 7, the bearing pin 9 with a certain joint in the chain 8 hangs in the hook groove of hook 3 then, but operating grip body 1 rotates pipe 7 with that, with installation or removal pipe 7.

From the above mentioned as can be known, after being provided with chain 8 on traditional adjustable wrench, both can clamping the workpiece of symmetry polygonal cross-section---as bolt, nut etc., workpiece that can also the clamping circle---as pipe etc., widened the scope of application of traditional adjustable wrench greatly.

Claims
