Abstract
The utility model relates to a dovetail nut wrench, in particular to a tool for mounting and demounting dovetail nuts. The dovetail nut wrench is simple in structure and convenient to use and can mount and demount the dovetail nuts fast and conveniently. The dovetail nut wrench comprises a handle and is characterized in that a tubular head portion is arranged at the top of the handle, and a pair of notches corresponding to dovetails of the dovetail nuts is arranged on the tubular head portion.
Description
Technical field
The utility model relates to a kind of dovetail nut spanner, specifically, relates to a kind of instrument that the dovetail nut is carried out installation and removal.
Background technology
The dovetail nut is the part commonly used of building field, and its structure is that the dovetail by nut body and nut body both sides constitutes; This dovetail nut need use common wrench usually, comes the dovetail nut is carried out installation and removal through the hexgonal structure of nut body.This mode inefficiency, all very inconvenient to the installation and removal of dovetail nut.
When the workman operates at the scene, generally do not use common wrench that the dovetail nut is loaded and unloaded; And be to use hammer, through beaing the dovetail part of dovetail nut, come the dovetail nut is loaded and unloaded; The fragile dovetail nut of this mode, and operating efficiency is also very low.
Summary of the invention
The utility model is exactly to the problems referred to above, provides a kind of simple in structure, easy to use, and the dovetail nut is loaded and unloaded dovetail nut spanner efficiently.
For reaching the above-mentioned purpose of the utility model; The utility model adopts following technical scheme; The utility model comprises handle, and the top of its structural feature handle is provided with tubular head, and an end of described tubular head is provided with the corresponding a pair of gap of the dovetail of dovetail nut.
As a kind of preferred version of the utility model, the two ends of described tubular head are provided with a pair of gap, and the gap at tubular head two ends is vertical each other.
As the another kind of preferred version of the utility model, the end of described handle is set to taper, and the handle middle part is provided with bending.
The beneficial effect of the utility model: 1, simple in structure, be easy to production and processing: the utility model main member is handle and tubular head, only needs after offering gap on the tubular head, and tubular head is combined with handle to get final product; Member is few, and is simple in structure.
2, quick for installation to the dovetail nut: the gap of the utility model through tubular head matches with the dovetail of dovetail nut, re-uses handle and comes the dovetail nut is loaded and unloaded; Reach easy to use, labour-saving purpose, improved operating efficiency.
3, easy to use: the utility model all is provided with gap at the tubular head two ends, and the vertical each other setting of the gap at tubular head two ends, and this makes also is convenient to the loading and unloading to the dovetail nut in small space; In addition, the end of the utility model handle is set to taper, and the handle middle part is provided with bending; Can through handle to the iron wire in building site install, work such as pretension; Function is many, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to view.
Fig. 4 is the structural representation of dovetail nut.
1 is that gap, 2 is that tubular head, 3 is that handle, 4 is that bending, 5 is that dovetail, 6 is the dovetail nut in the accompanying drawing.
The specific embodiment
The utility model comprises handle 3, and the top of handle 3 is provided with tubular head 2, and an end of described tubular head 2 is provided with the dovetail 5 corresponding a pair of gap 1 with dovetail nut 6.
As a kind of preferred version of the utility model, the two ends of described tubular head 2 are provided with a pair of gap 1, and the gap 1 at tubular head 2 two ends is vertical each other.
As the another kind of preferred version of the utility model, the end of described handle 3 is set to taper, and handle 3 middle parts are provided with bending 4.
Use below in conjunction with description of drawings the utility model: when dovetail nut 6 is loaded and unloaded, match through the gap 1 of tubular head 2 and the dovetail 5 of dovetail nut 6, rotating handles 3 gets final product then.If in narrow space, when tubular head 2 can't be matched with the dovetail 5 of dovetail nut 6 by handle 3 restrictions, then can use of dovetail 5 cooperations of the gap 1 of tubular head 2 other ends, and it is loaded and unloaded with dovetail nut 6.
The building site iron wire is being installed, during pretension, can iron wire levered up, levering up the back and carry out pretension through 3 pairs of iron wires of handle through the tapered end of handle 3, easy to use.
Claims (3)
