Abstract
The invention discloses a simple one-way wrench, which comprises a handle. The wrench takes the shape of a Z, and the jaw of the wrench takes the shape of a U. The simple one-way wrench has the benefits that as the wrench takes the shape of the Z, the jaw can enter into a narrow space, and the handle of the wrench is out of the narrow space; and thus, the screw installation and dismantlement efficiency is greatly increased.
Description
Technical field
The present invention relates to a kind of hardware ﹠ tools, be specifically related to a kind of Simple one-way wrench.
Background technology
Existing spanner for dismounting screw, nut, the head volume that mostly is spanner is larger, all can not change the direction of moment, the compactness of screw, nut arrange to(for) dismounting narrow space, installation are very difficult, although universal wrench is also arranged in the prior art, be a pair of gimbal structure because it adopts, processing when compact Screw, primary nut are installed, its turning efficiency is very restricted, and causes staff's operating efficiency low.For example, lay in the cable process at unmanned plane, to install fastening to switchboard, the aircraft wing adaptor connector of unmanned plane, in the process of installing, because the model of the toggle switch on the switchboard is special, the operating space is narrow and small, and conventional sleeve exceeds sleeve diameter because of the switching toggle space, can't operate.In addition, common shfting wrench can touch other connector because of by operating space impact on every side, also can't guarantee to be fastenedly connected, and potential safety hazard is very large, and efficient is extremely low.
Summary of the invention
The object of the invention is to propose a kind of Simple one-way wrench, make the ineffective problem of spanner to solve dismounting narrow space of the prior art.
For reaching this purpose, the present invention by the following technical solutions:
A kind of Simple one-way wrench comprises handle, and described spanner is " Z " type, and the mouth of pulling of described spanner is " U " type.
Preferably, be provided with the Antislip plastic bed of material on the described handle.
Preferably, be provided with installing hole on the described handle.
Beneficial effect of the present invention is: because spanner is " Z " type, pull mouthful deeply to narrow space so can make, and the handle of spanner is outside narrow space, thereby spanner has greatly improved the efficient of screw installation and removal.
Description of drawings
The structural representation of a kind of Simple one-way wrench that Fig. 1 provides for the specific embodiment of the invention 1.
Among the figure:
1, handle; 2, pull mouth; 3, installing hole.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment, as shown in Figure 1, a kind of Simple one-way wrench of the present invention, comprise handle 1, be provided with installing hole on the handle 1, be convenient to when spanner does not use, can be fixed in the tool box, be provided with the Antislip plastic bed of material on the handle 1.
Spanner is " Z " type, makes handle 1 and pulls mouth 2 not in same plane, makes its restriction that is not subjected to narrow space, and the mouth 2 of pulling of spanner is " U " type.Integral body of the present invention is more frivolous, is applicable to operation in the narrow space.
The present invention only needs to pull the side that mouth 2 places screw in use, owing to the length of pulling mouth 2 is little, is easy to extend in the space of dense arrangement, and rotary handle 1 makes screw pull mouthful 2 interior rotations in " U " type, thereby makes under the screw dismounting; The process that screw is installed is opposite with the process using method of dismounting screw.
Spanner of the present invention has greatly improved the efficient of screw installation and removal.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (3)
