Description

An adjustable wrench

technical field

The utility model relates to an adjustable wrench, which belongs to the technical field of tools. the

Background technique

Pipe wrench, adjustable wrench and other tools are often brought in inspection work in oil and gas field production, but the labor intensity of employees is increased due to the inconvenience of carrying various tools. In addition, switching various valves during work is a relatively frequent job, but The opening of the currently used "F" wrench is dead and cannot be adjusted, and when the F wrench is stuck on the valve handwheel, it shakes left and right, which is easy to slip and cause accidental injuries to employees, posing a safety hazard. At the same time, it is a waste of switching operations. Time, thus, also affects oil and gas field production and the speed at which employees operate. the

Contents of the invention

In order to overcome the shortcomings of the prior art, the utility model provides an adjustable wrench. the

An adjustable wrench, one end of the adjusting rod is connected with a movable clamp head, the rod body of the adjusting rod has an external thread buckle and a plane, one end of the movable clamp head is a first plane, and the peripheral body side of the movable clamp head has a plane and a stepped plane; One end of the handle is a round nozzle, the other end of the handle is connected to the fixed pliers head, one end of the fixed pliers head is the second plane, and the circumferential body side of the fixed pliers head has a plane and a stepped plane; the other end of the handle has an internal thread hole, The fixing screw passes through the inner thread hole wall of the handle through the threaded buckle, the adjusting rod is connected with the handle, and the adjusting rod and the handle are positioned through the contact plane of the fixing screw. the

The utility model has the advantage that in the production of oil and gas fields, the previous "F" cannot be adjusted at will during use, and it solves the problem of left and right shaking and slipping when the F wrench switches the valve, especially solves the problem of employees traveling during production. There are fewer tools to carry during the inspection work, which reduces the labor intensity of employees, improves the working time rate, is convenient and quick to operate, and eliminates potential safety hazards. the

Description of drawings

A more complete and better understanding of the invention, and many of its attendant advantages, will be readily appreciated by reference to the following detailed description when considered in conjunction with the accompanying drawings, but the accompanying drawings illustrated herein are intended to provide a further understanding of the invention , constituting a part of the utility model, the schematic embodiment of the utility model and its description are used to explain the utility model, and do not constitute an improper limitation of the utility model, as shown in the figure:

Fig. 1 is the structural representation of the utility model. the

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the

Detailed ways

Obviously, many modifications and changes made by those skilled in the art based on the gist of the utility model belong to the protection scope of the utility model. the

Embodiment 1: As shown in Figure 1, an adjustable wrench, one end of the adjusting rod 2 is connected to the movable clamp head 3, the rod body of the adjusting rod 2 has an external thread buckle and a plane 9, and one end of the movable clamp head 3 is the first plane 5. There are planes and step planes on one side of the circumferential body of the movable clamp head 3;

One end of the handle 1 is a round nozzle 7, the other end of the handle 1 is connected to the fixed pincer 4, and one end of the fixed pincer 4 is the second plane 6, and one side of the circumferential body of the fixed pincer 4 has a plane and a stepped plane;

The other end of the handle 1 has an internally threaded hole, and the fixing screw 8 passes through the wall of the internally threaded hole of the handle 1 through a screw thread.

The adjusting rod 2 is connected with the handle 1 and positioned by the fixing screw 8 contacting the plane 9 . the

After the movable clamp head 3 and the fixed clamp head 4 are adjusted by rotating the handle 1 or rotating the movable clamp head 3, tighten the fixing screw 8 to be used as a pipe clamp to switch valves, load and unload round pipes, and square plugs, etc., the first plane 5 , After the second plane 6 is adjusted, it can be used as a wrench, and the round nozzle 7 can be used to tighten the pumping well sealing packing box,

Embodiment 2: As shown in FIG. 1 , an adjustable wrench includes: a movable pliers head 3, a fixed pliers head 4, a fixing screw 8, a handle 1, and a set of thread adjustment devices. the

Movable pliers head part: use two round steels with a diameter of 18mm and a length of 90mm, remove one side of the round steel with a thickness of 4mm and wash the plane, then use a lathe on the plane to the shape of the inverted teeth, and then use a round steel with a diameter of 18mm and a length of 170mm, One side removes thick 5mm back cover 150mm long " T " screw thread and a diameter 18mm, and long is that 90mm is welded together to form a movable head 3 with lathe to go out tooth shape round steel. Then use a round steel sleeve Tr20 buckle with a diameter of 26mm and a length of 150mm to form a handle 1 with a 300mm round pipe, and then form a fixed handle 1 with a diameter of 18mm and a length of 90mm with a lathe to the round steel of the inverted tooth shape. Clamp head 4. Drill a 6mm hole tapping buckle at the welding place between the fixed pliers head 4 and the handle 1 to connect the fixing screw 8 . Set screw 8 is reversed into pattern shape with the threaded button other end of a head cover long 12mm M6 of 10mm in diameter, long 30mm round steel. the

Put the movable pliers head 3 into the Tr20 buckle of the handle 1, and then put the fixing screw 8 into the M6 screw thread set on the fixed pliers head and the handle. When using, just loosen the fixing screw 8 and adjust it with the handle 1. It is also possible to adjust the opening of the opening or use the movable clamp head. After adjusting the opening, the fixing screw 8 is screwed and it can be used. the
