Abstract

The utility model relates to a universal spanner, comprising a crank 1, a static jaw clamp 3 which is positioned on one end of the crank 1 is provided with a locking and removing acting surface 4, and a dynamic jaw clamp 2 which is connected with one end of the crank 1 and is corresponded with the static jaw clamp 3, a throat domain 5 which can contain the locked and removed component is arranged in the dynamic jaw clamp 2, and the throat domain 5 is provided with a plurality of domain walls, the locking and removing acting surface 4 is a circular arc segment, and the surface of which forms the hammered racked shape: the dynamic jaw clamp 2 is hinged with the crank 1, the throat opening of the throat domain 5 on the upper side of the dynamic jaw clamp 2 is corresponded with the static jaw clamp 3; the domain wall of the throat domain 5 forms the working surface S1, S2, S3, S4 which are contacted with the locked and detached object, and an equal included angle is respectively formed among the working surfaces. The advantages of the utility model are 1. the universal spanner can not only lock and remove the cap nuts which have edges, angles and have all kinds of formats, such as: the metric system, the British system, and the pipes such as: a running water pipe and a pipe joint can be locked and removed; 2. the clamped effects on the locked and removed component are good, in the process of stress application, and the phenomena of slipping and pulling out from the jaw opening can not occur.

Description

Monkey wrench

Technical field

The utility model relates to a kind of monkey wrench, belongs to the hardware ﹠ tools that uses in people's daily life.

Background technology

Spanner roughly is divided into two big classes, and a class is an adjustable wrench, and another kind of is fork spanner.The nut lock why adjustable wrench can adapt to plurality of specifications unloads, it mainly is to embody with cooperating of quiet jaw by an adjustable movable jaw, as if this can embody its advantage, but it can only be applicable to or be called and be used for hexagonal (hexagon)nut, so the limitation of being used; For fork spanner, since its two jaw all with the body integral production, so the size of its jaw mouth can not change, as will the lock of 6 inches, 8 inches, 10 inches, 12 inches etc. nut being unloaded, must use the fork spanner of the jaw mouth that matches so respectively, although fork spanner can respectively be established jaw at the two ends of body, a lock that also can only satisfy fork spanner at the nut of two kinds of specifications unloads, thereby has the single shortcoming of lock removing nut specification.The object that unloaded by lock of this two classes spanner only is the nut of having edges and corners, and is then powerless for the cylindrical body as running water pipe and joint for pipe and so on; Also have, aforementioned two class spanners are made the pincers of time spent to hold effect relatively poor unloading thing, cause the phenomenon that occurs frequently and now skid or deviate from and so on from the jaw mouth at the afterburner process intermediate frequency.

Summary of the invention

Task of the present utility model be to provide a kind of can adapt to the hexagonal (hexagon)nut of plurality of specifications lock unload and can to other as running water pipe and pipe joint thereof lock unload, to being held effective monkey wrench by lock inloading part pincers.

Task of the present utility model is finished like this, a kind of monkey wrench, and it comprises one handle 1, one quiet jaw 3, quiet jaw 3 is positioned at one of handle 1 end, has a lock and unloads acting surface 4, one moving jaws 2, be connected with one of handle 1 end, and corresponding with quiet jaw 3, have one and can hold into by the larynx territory 5 of lock inloading part, larynx territory 5 has a plurality of territories wall, it is an arc section that described lock unloads acting surface 4, and this arc section surface forms ups and downs spline-simulating; Described moving jaw 2 is hinged with handle 1, and the aditus laryngis in the larynx territory 5 on it is corresponding with quiet jaw 3; The territory wall in described larynx territory 5 forms and is unloaded working face S1, S2, S3, the S4 that thing contacts by lock, is formed with an angle that equates between them respectively.

Angle described in the utility model is 120 °.

Working face S1 described in the utility model and S4 are parallel to each other.

Advantage of the present utility model: 1. both can lock the nut that unloads all size of having edges and corners, metric system English system, and can the tube lock of running water pipe and tubular joint and so on have been unloaded again; 2. effective to being held, as can in afterburner process, not occur skidding, deviate from from jaw mouth phenomenon by the pincers of lock inloading part.

Accompanying drawing and drawing explanation

Fig. 1 is the utility model example structure figure.

Fig. 2 is another enforcement structure chart after the utility model Fig. 1 changes slightly.

The specific embodiment

In Fig. 1, a handle 1, these handle 1 one ends are quiet jaw 3, this quiet jaw 3 and handle 1 integral production, and the lock of quiet jaw 3 to unload acting surface 4 be an end circular arc interval, the interval surface of this circular arc forms curved tooth.Offer lock shaft hole 6 at a end, and the base portion of moving jaw 2 also offers pin shaft hole 8, passes through pin shaft hole 8,6 in regular turn by bearing pin 7, make jaw 2 and handle 1 hinged near the handle 1 of quiet jaw 3.Also keeping somewhere at the base portion of moving jaw 2 has quiet jaw groove 9, and the lock that is beneficial to quiet jaw 3 unloads acting surface 4 activities.The territory wall in larynx territory 5 constitutes and can unload working face S1, S2, S3, the S4 that thing contacts well with by lock.Working face S1 and S2, working face S2 and S3, working face S3 is 120 ° of identical angles each other with S4, and promptly the angle between S1 and the S2 is 120 °, and other is analogized.And working face S1 is parallel with working face S4.

In Fig. 2, structure shown in this figure only is the dynamic and static jaw 2,3 of the equal tool in two ends that makes handle 1, and as seen it is the simple stack of Fig. 1 structure, just not will be understood that the relative Fig. 1 structure of structure shown in Figure 2 has excellent part in view of this.

During use, nuts are aimed in larynx territory 5, and actuating handle 1 makes lock unload tooth on the working face 4 with aditus laryngis or claim the block of jaw mouth, by the effect repeatedly to handle 1, realizes the nut lock is unloaded; In this way running water pipe is carried out fastening or loose opening, the body of running water pipe is in the larynx territory 5, during actuating handle 1, lock unloads acting surface 4 as cooperating as the tooth moving jaw 2 that pipe vice is held, by effect repeatedly to handle 1, realization is to fastening or loose the opening of pipe, and visible the utility model can also play the function of the pipe vice that the pipeliner uses.
