Abstract
The utility model belongs to a kind of utility, particularly a kind of particular surroundings spanner, it is characterized in that comprising: working end, connecting portion, handle and power-assisted portion; Described working end there are tiger's jaw and counterbore; Described connecting portion connects working end and handle; Described handle has counterbore and a round hole; Described power-assisted portion inserts in the round hole of handle if desired.The utility model is a kind of dismountable, facilitates workman's parbuckle screw and the spanner that designs under being directed to special operation environment.Especially, spanner comprises the connecting portion of three kinds of different lengths, meets the requirement of the operating surface operation of different depth; Be designed with to select and use power-assisted portion, be used for the not easily detachable part because of reasons such as degree of tightness corrosions.
Description
Technical field
The utility model belongs to a kind of utility, particularly a kind of particular surroundings spanner.
Background technology
Conventional spanner such as solid wrench, adjustable wrench are all the spanners being applicable to operation in a horizontal plane, and when running into special operating environment, they then have no usage.In addition, many outdoor places or because year reason of a specified duration, there are some parts and cause because getting rusty the spanner commonly used not easily to be turned on.Existing spanner generally can not meet mission requirements, and the special key that can solve problems is general more accurate and involve great expense.
Summary of the invention
The utility model, for the problems referred to above, discloses a kind of particular surroundings spanner.Cannot carry out parbuckle screw operation to solve under many complex environments, the utility model adds a connecting portion, makes working space rise to three dimensions from two dimensional surface, substantially increases the efficiency of operation.Considering some screw because the reason such as getting rusty causes not easily turning on, and the utility model adds power-assisted portion especially, solves this type of corrosion problem by increasing moment of torsion.
Technical solution
In order to achieve the above object, particular surroundings spanner described in the utility model, is characterized in that comprising: working end, connecting portion, handle and power-assisted portion; Described working end there are tiger's jaw and counterbore; Described connecting portion connects working end and handle; Described handle has counterbore and a round hole; Described power-assisted portion inserts in the round hole of handle if desired.
Further, described working end is that band depression the square of tiger's jaw connects collar plate shape steel part; Have a square counterbore in integrated disc portions center, square counterbore diagonal is on the axis of working end.
Further, described connecting portion is four-prism steel part, and the square counterbore on its cross-sectional sizes and working end matches; Described connecting portion has three kinds of length to use, and is connected between working end counterbore and handle counterbore.
Further, its structure of described handle is similar to working end, and its decreased food is longer than working end; The circular portion centers in handle front end has a counterbore, and close afterbody has a circular perforate, and its center is on handle axis.
Further, described power-assisted portion is a round bar, and its cross section is identical with handle afterbody round hole area.
Beneficial effect
The utility model have employed connecting portion and solves the problem much run into when plane operation, and after being raised by handle, working space has risen to solid space from two dimension; Provide the connecting portion of three kinds of different lengths, solve and run into the problem that differing heights hinders plane; Use power-assisted portion, by increasing the easy many operation difficulties of not easily to turn on screw because of corrosion of moment of torsion.This spanner structure is simple, material is easy to get, feature richness, can meet the job requirements of a lot of complex environment.

Fig. 1 is front view of the present utility model and top view;
Fig. 2 is the connecting portion schematic diagram of the utility model three kinds of differing heights;
Fig. 3 is the schematic diagram of the utility model connecting portion under difference assembling mode;
Fig. 4 is operation schematic diagram under some particular surroundings of the utility model;
In Fig. 1: 1-working end, 2-connecting portion, 3-handle, 4-power-assisted portion
A is front view, and b is top view.
In Fig. 2: a is raw footage connecting portion, b is two times of length connecting portions, and c is triple-length connecting portion.
In Fig. 3: a is the spanner turned clockwise after 90 °, b is rotated counterclockwise the spanner of 90 °.
In Fig. 4: a is longer working face upper ejector lever operation schematic diagram, b is that screw is at recess spanner operation schematic diagram.
Detailed description of the invention
Detailed description of the invention of the present utility model is described below in conjunction with accompanying drawing:
As Fig. 1, working end (1) is connected with handle (3) by connecting portion (2), power-assisted portion (4) can be selected where necessary to increase moment of torsion, turn on the part of some corrosions;
The connecting portion of three kinds of different lengths is illustrated, to adapt to the operation on the operating surface of different depth in Fig. 2;
Fig. 3 is the top view under this spanner two kinds of different connection angles, when the operation of some special angle, can consider the connection angle changing handle and working end;
Fig. 4 lists two kinds of special operating environments, Fig. 4 (a) is long and narrow operating surface operation chart, when operating surface is long, part is attached to operating surface surface, hand will be difficult to hold handle operation, after adding connecting portion, improve the distance of handle and operating surface, thus hand can better be operated handle; Fig. 4 (b) is then that operating surface caves in and among parts, general spanner cannot operate this in this case, and the utility model is then good for this problem.
