Description
Technical field
The present invention relates to one kind to install and use tool, and in particular to the adjustable small-sized open spanner that a kind of small space uses
Hand.
Background technology
Due to science and technology and industrial expansion, improvement of living standard is more and more touched in people's life appliance each
The screw rod and nut of kind size.Therefore, screw rod, the assembling of nut, adjustment in household implements, particularly in the worked of repair
Cheng Zhong is required for being adjusted different size of nut, and the basic tool needed is exactly spanner.Spanner is divided into two kinds substantially,
Solid wrench and opening adjustable wrench.The opening width of adjustable wrench can be adjusted in the range of certain size, can twist different size
Bolt or nut.The regular jaw in flat pliers face of the design feature of the spanner with serration and the moving jaw for being capable of activity,
The openings of sizes of jaw can be changed by moving jaw.The opening of general spanner is all the regular polygon by regular shape,
It clamps nut side and is tightened or unscrewed operation.Existing spanner usually utilizes lever principle mostly there are one long handle, to increase
Force application arm, used in Automatic manual transmission, repair, safeguard when, twist the installation and dismounting of bolt, screw, nut.But there is long handle
Spanner, in some small spaces in use, will be very inconvenient or even can not use.Such as：Family, the toilet water in hotel
The disassembly and installation of leading hose coupling nut, since washing basin, closestool are mostly arranged by wall or corner, the spanner in repair
Using space it is limited.Therefore, in small space, nut or nut are removed and installed, needs to use a kind of suitable open-end wrench.
It, can be in the adjustable small-sized open-end wrench that small space uses therefore, it is necessary to a kind of more professional.
Invention content
The technical scheme is that：A kind of adjustable small-sized open-end wrench, is mainly made of, feature main body and mobile
It is：Main body semicircular in shape pie, on circular arc top, upper and lower surface is machined with handle, be machined on hand perforation above and below
Slot, in slot processing the screw rod that can be rotated is installed.Screw rod is fixed on by screw rod fixing axle in main body.This design is with most
Easy component achievees the purpose that use convenient for holding.Boring, lower surface opening T shapes are machined in the middle part of main body
Chamber is machined with 1-3, less the jaw of the regular hexagon on two sides, the opening both sides phase of jaw in the diameter end of main body semicircle
Mutually parallel and perpendicular to diameter or the straight flange of arc length.Jaw present situation meets nut international standard regular hexagon, convenient for clamping nut.
The diameter of main body is in below 150mm, it is therefore an objective to which miniaturization is convenient for using in small space.Simultaneously as using civilian
In terms of life, nut is all smaller, and torque does not need to be very big.Mobile's semicircular in shape pie, size are smaller than main body.In dome
End is trimmed and is in line, and the linear edge face trimmed is machined with mobile's ends screw, mobile's ends screw in main body
Screw flight, which matches, to be engaged.The T-shaped structure of protrusion, the T shape chamber phases of T-shaped structure and main body are machined in mobile's upper surface middle part
Cooperation.Mobile's ends screw is exactly the discontinuous helical teeth being mutually parallel, and its spacing can be stung with screw flight precision-fit
It closes.The diameter end of mobile's semicircle is machined with the 1-3 consistent with the jaw quantity of main body, the regular hexagon on few two sides
Jaw, the opening both sides of jaw are mutually parallel and perpendicular to diameter or the straight flange of arc length；Each jaw opening phase of mobile
The same side is machined with the convex nipper of mobile that 5mm-10mm is thick, protrusion stretches into main body jaw, the height of the convex nipper of mobile and master
The consistency of thickness of body, width are consistent with the length on jaw one side.The design of the convex nipper of mobile becomes the width of jaw can be with
Adjustment.Though it is small to realize spanner, an adjustable adjustable wrench of opening.
In above-mentioned technical proposal, the lower surface of the main body and the upper surface of mobile pass through the T shapes chamber of processing and T shape knots
Structure precision connects.T shape chambers both ends are not closed, and can be dismantled mobile and out be entered with installation activity body.Mobile passes through activity
On body end head thread and main body, the screw flight precision-fit of screw rod is connected, can be under screw rod rotation, along main body spiral shell
The axially opposing main body of bar fixing axle is slided.The screw rod fixing axle can be rapid to take out by dismantling the nut of end, unloads
Screw rod.This design is to turn to match and dismantle convenient for main body and the mutual of mobile.
In above-mentioned technical proposal, the convex nipper of mobile of each jaw, before the screw rod rotation in main body, all same
One direction, precision are fitted on the same side wall of jaw, while the main body of the side is concordant with mobile edge.This design, ensures
Slip of the jaw with mobile, opening size descending variation.The opening width one of 2-3 jaw of the main body
It causes or inconsistent.One main body can be installed with the mobile of multiple and different specifications to be used cooperatively.This design can form this hair
Bright different size model.
Compared with existing spanner, the present invention has following advantageous effect：（1）Low-profile is beautiful, without clumsy long hand
Handle.To it is certain install and be inconvenient to the household electrical appliance unloaded down or other devices for, this spanner is undoubtedly best selection.
It is time saving and energy saving, is also convenient for carrying.（2）It is easy to make simple, it is of low cost.（3）It is easy to use.
