Abstract

The utility model discloses a novel movable spanner which is used to tightly screw or loosen a screw cap and a bolt. The novel movable spanner is mainly composed of a fixed clamp head 1, a movable clamp head 3, a handle 7, a connecting rod 9, a hinge 4, a hinge 6, a hinge 11, cover plates 12 and a rivet 13, wherein a sliding slot 2 is manufactured on the upper end of the fixed clamp head 1, one side of the lower end is provided with a handle which is manufactured with the fixed clamp head into a whole, and the other end is provided with another handle 7 through a hinge. The movable clamp head 3 is installed in the sliding slot 2 and can slide along the sliding slot 2. Two cover plates 12 are respectively arranged on the upper surface and the lower surface of the movable clamp head 3 and are installed on the fixed clamp head 1 through the rivet 13. One end of the connecting rod 9 is connected with the lower end of the movable clamp head 3 through the hinge 4, and the other end is connected with the handle 7 through the hinge 11. The novel movable spanner has the advantages that the work is reliable and can not slide, and the use and transportation are convenient.

Description

Novel adjustable wrench

One, technical field

The utility model relates in a kind of industrial production and the daily life instrument commonly used, specifically is exactly a kind ofly to be used for tightening or the instrument of loosen nut and bolt.

Two, technical background

In all fields almost such as machine-building, household electrical appliance, furniture, daily necessities, being threaded is to use the widest method of attachment.Realize being threaded, with regard to handy spanner with nut or screw-driving or unclamp.In present prior art, tightening or unclamping screw thread instrument commonly used has three kinds of open-end wrench, double offset ring spanner and monkey wrenches.The shortcoming of open-end wrench and double offset ring spanner is nut or the screw that a kind of spanner of specification can only be used for a kind of specification, in order to satisfy the needs of twisting different size nut or screw at any time, must be ready to the complete set of wrench open-end wrench or double offset ring spanner formed by more than ten, the complete set of wrench one is that weight is big; Two must be from more than ten choosing a suitable spanner when being to use the spanner, use and carry all very inconvenient.Though monkey wrench can one spanner is used for the screw or the nut of plurality of specifications,, make the very bad grasp of adjusting of monkey wrench openings of sizes owing to regulate between the worm screw of wrench opening size and tooth bar gappedly.Opening has been turned down, and spanner can't clip nut; Opening is transferred big, skids easily when tightening.

Three, technical scheme

It is non-slip that the purpose of this utility model provides a kind of reliable operation, uses and carry novel adjustable wrench very easily simultaneously.

For achieving the above object, the technical solution adopted in the utility model is as follows:

Novel adjustable wrench mainly comprises fixed chuck, active chuck, handle, connecting rod, three hinges, two cover plates and two rivets compositions.The upper end of fixed chuck is shaped on chute, on one side there is a handle that is connected as a single entity with fixed chuck the lower end, another side is equipped with another handle by hinge.Active chuck is installed in the chute of fixed chuck, and it is upper and lower respectively to have a cover plate to be installed on the fixed chuck with rivet.One end of connecting rod is connected with active chuck by hinge, and the other end is connected with handle by hinge.

Connecting rod also can be made into adjustable length: the two ends of connecting rod are shaped on left-handed respectively and the dextrorotation internal thread, and two hinges that are connected with the connecting rod two ends link respectively a left-handed screw and right handed screw, and two screw rods screw in respectively in the corresponding internal thread in connecting rod two ends.

Adopted technique scheme, when the needs tightening nuts, handle is opened, active chuck moves down under the pulling of connecting rod, the hexagonal hole that fixed chuck and active chuck are surrounded enlarges, and is enclosed within on the nut with this hexagonal hole then, holds and rotary handle, this moment, active chuck moved up under the promotion of connecting rod, and nut is clamped and and then tightens.The power of executing when tightening on handle is big more, and the clamping force on the chuck is also correspondingly big more, and very close to each other between chuck and the nut, therefore its reliable operation is non-slip, because it does not need painstakingly to regulate extent of opening in use, and in light weight, so it uses and carries all very convenient.Particularly if adopt the connecting rod of adjustable length integral expression, just can be adjusted at the size of the hexagonal hole that surrounds by active chuck and fixed chuck under the initial shape, so that make novel adjustable wrench more be applicable to the nut that size is bigger than normal or less than normal, so just can one novel adjustable wrench, be used for the nut of the most frequently used ten plurality of specifications of producing, live.

Four, description of drawings

Fig. 1 is the front view of novel adjustable wrench;

Fig. 2 is the cutaway view of Fig. 1 along the A-A direction.

Five, the specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is further described:

In Fig. 1 and Fig. 2, the utility model novel adjustable wrench mainly is made up of fixed chuck 1, active chuck 3, handle 7, connecting rod 9, hinge A4, hinge B6, hinge C11, cover plate 12 and rivet 13.The upper end of fixed chuck 1 is shaped on to slide and is pickled with grains or in wine 2, on one side there is a handle that is made as one with it lower end, the other end is equipped with another handle 7 by hinge B6.Active chuck 3 is installed in the chute 2 and can slides along chute 2." V " shape structure that the upper end of chute 2 and active chuck 3 is 120 degree angles (is used for hex nuts 5.If being used for this angle of square nut can spend with 90).The upper and lower of active chuck 3 respectively has a cover plate 12 usefulness rivets 13 to be installed on the fixed chuck 1, and the effect of cover plate 12 is and slides poor 2 slideways that form active chuck 3 together.One end of connecting rod 9 is connected with the lower end of active chuck 3 by hinge A4, and the other end is connected with handle 7 by hinge C11.Connecting rod can be made into fixed length, also can be made into adjustable length.The connecting rod of fixed length is exactly a common rod member, and two ends are shaped on hinge.Illustrated in figures 1 and 2 is a kind of adjustable length connecting rod.It is to be shaped on 10, two screw rods of a left-handed screw 8 right handed screw that have respectively that left-handed and dextrorotation internal thread and hinge A4, hinge C11 be connected as a single entity respectively to screw in respectively in the corresponding internal thread in connecting rod 9 two ends at the two ends of connecting rod 9.When rotating connecting rod 9 forward or backwards, can adjust the length that two screw rods stretches out from connecting rod 9 two ends internal threads, thereby be adjusted at the degree of fixed chuck 1 and active chuck 3 openings under handle 7 open configurations, so that be fit to the use of the bigger or less nut 5 of size.
