Provided is a pair of rotating pliers. The pair of rotating pliers comprises a left plier body (1) and a right plier body (2), the left plier body (1) is formed by integrating a plier mouth portion (11) and a grip (12), the right plier body (2) is formed by integrating a plier mouth body (21) and a handle (22), and the left plier body (1) and the right plier body (2) are movably connected through a rotating shaft (4) in the middle. The pair of rotating pliers is characterized in that a plier mouth cavity (6) after the plier mouth portion (11) and the plier mouth body (21) are closed is of a diamond shape, wherein two opposite angles are respectively 120 degrees. Compared with the prior art, the pair of rotating pliers has the advantages that the two opposite angles of the plier mouth cavity are respectively 120 degrees so that the plier mouth cavity can be attached to the outer surface of a nut tightly, and the pair of rotating pliers can clamp the nut tightly, prevent the nut from slipping and be applicable to nuts of different sizes. Besides, a self-lubricating bearing is arranged on a connection position of the plier bodies, a friction coefficient of the rotating shaft is small, relative motion between the left plier body and the right plier body is flexible, and the pair of rotating pliers is laborsaving and easy to use.

Description

A kind of wrench

Technical field

The utility model relates to a kind of hardware ﹠ tools, especially refers to a kind of wrench for the dismounting nut.

Background technology

When the dismounting mechanical device, want inevitably the various bolts of dismounting, nut, but owing to varying in size of different nuts, need to prepare associated many monkey wrench of instrument or use adjustable openings size, because monkey wrench is the size of being controlled opening by screw thread, firmly excessive when the dismounting nut, cause easily the damage of screw thread or the slippage of monkey wrench; Secondly, in practical operation, because the restriction in dismounting space, common wrench often can't normally be used, and needs open-end wrench, and the working position of open-end wrench is open type, easily slippage and cause the injured of staff, the structure of therefore existing spanner is further improved.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of design ingenious, simple in structure for above-mentioned prior art problem, can be used for narrow and small dismounting space and can be applicable to different greatly a kind of wrenches of primary nuts.

The utility model solves the problems of the technologies described above the technical scheme that adopts: this wrench, include the right caliper body that left caliper that jaw section and handle be integrated and jaw body and handgrip are integrated, described left caliper and right caliper body are movably connected by the rotating shaft at middle part, it is characterized in that: the jaw chamber after described jaw section and the jaw body closure is respectively 120 ° rhombus for two diagonal angles wherein.

As improvement, the structure that the rotating shaft by the middle part of described left caliper and right caliper body is movably connected is: the middle part of described left caliper and right caliper body is respectively arranged with through hole, be equipped with rotating shaft in the described through hole left caliper and right caliper body are movably connected, and between through-hole wall and rotating shaft, be provided with suitable self-lubricating bearing.

As improvement, the inwall of described rotating shaft and self-lubricating bearing is that interference fit tightens together.

As improvement, described left caliper is provided be used to the left edge of a knife of cutting off object and right caliper body and is provided be used to the right edge of a knife of cutting off object, and when left caliper and right caliper body closed up, the described left edge of a knife and the right edge of a knife were for to being combined.

As improvement, be equipped with respectively on described handle and the handgrip be used to shaking hands more comfortable and protective sleeve easily.

Compared with prior art, the utility model adopts the jaw chamber after described jaw section and the jaw body closure to be respectively 120 ° rhombus for two diagonal angles wherein; And the middle part of described left caliper and right caliper body is respectively arranged with through hole, is equipped with rotating shaft in the described through hole left caliper and right caliper body are movably connected, and be provided with suitable self-lubricating bearing between through-hole wall and rotating shaft.Advantage of the present utility model is: the jaw chamber is respectively 120 ° rhombus for two diagonal angles wherein, jaw chamber and nut outer surface can be fitted tightly, not only can make wrench tightly block nut and prevent its slippage, also make this wrench applicable to the nut of different sizes, also have, be provided with self-lubricating bearing in the caliper junction, make the coefficient of friction of rotating shaft less, can make the relatively activity between the left and right caliper become more flexible, thereby it is more laborsaving, lighter that wrench is used; Have, be provided be used to the sheared edge of cutting off object on the described left and right caliper, can shear the wires such as steel wire, iron wire, use more conveniently, range of application is wider.
