Description

Multiple degrees of freedom spanner

Technical field

The utility model relates to multiple degrees of freedom spanner, belongs to hardware & tools field.

Background technology

Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.

Spanner is divided into two kinds substantially, solid wrench and adjustable wrench.

The former refers to the spanner having fixing numeral to write, and the latter has been exactly monkey wrench.1. fork spanner: one or both ends are shaped with the opening of fixed dimension, in order to twist nut or the bolt of certain size.2. double offset ring spanner: two ends have the working end of band hexagon ring or 12 corner apertures, are applicable to working space narrow and small, can not use the occasion of common wrench.3. combination wrenches: one end is identical with single head fork spanner, and the other end is identical with double offset ring spanner, bolt or the nut of same size are twisted in two ends.4. adjustable wrench: A/F can regulate within the scope of certain size, can twist bolt or the nut of different size.The design feature of this spanner is that the flat pliers that regular jaw is made with serration is recessed; Flat pliers mouth is made in moving jaw one end; The other end makes the recessed jaw with serration; Press worm screw downwards, moving jaw can take off rapidly, exchanges jaw position.5. hook spanner: also known as crescent wrenches, for twisting the restricted jam nut of thickness etc.6. box spanner: it by multiple band hexagon ring or 12 corner apertures sleeve and be furnished with the multiple accessories such as handle, extension bar and form, be specially adapted to twist bolt or the nut of the very narrow and small or very depths of caving in, status.7. inner hexagon spanner: the bar-shaped spanner of hexagonal becoming L shape, is exclusively used in and twists soket head cap screw.The model of inner hexagon spanner is that the size of bolt has national standard according to the opposite side size of six sides.Purposes: specialize in round nut use that is fastening or that dismantle in lathe, vehicle, plant equipment.8. torque spanner: it can demonstrate applied moment of torsion when twisting bolt or nut; Or after the moment of torsion applied arrives setting, light or audible signal can be sent.Torque spanner is applicable to have to torque the dress specified clearly.

Current existing solid wrench two ends use part is provided with six square tube holes for circular protrusions, being laterally projecting structure, easily damaging in use although this structure can be satisfied the demand to outside hand to meet the six usual ends of square tube pore structure.

Utility model content

The utility model for current existing solid wrench two ends use part for circular protrusions is provided with six square tube holes, in order to the satisfied six usual ends of square tube pore structure are laterally projecting structure, but although this structure can be satisfied the demand in use to the problem that outside hand easily damages, devise multiple degrees of freedom spanner.

The technical scheme in the invention for solving the technical problem is:

This multiple degrees of freedom spanner, its structure comprises: matrix, the first clamp, the second clamp, the first set bolt, the second set bolt, hold-down nut, described matrix is elongate structure, its cross section is square, base end center is provided with accommodation first clamp and the square blind hole of the second clamp, described square blind hole cross section is square, the hole wall of blind hole is provided with manhole, relative two the featheredge edges of described square blind hole are provided with lozenges structure, described lozenges structures slope angle is 2a, first clamp is trapezium structure, the angle of inclination of described first clamp two relative waists is a, one end that first clamp width is large is provided with interior six square tube holes, one end that first clamp width is little is provided with manhole, first set bolt is through the manhole of matrix end manhole and the little one end of the first clamp width, first set bolt end coordinates with hold-down nut.

The thickness of the square blind hole of described base end center is greater than the thickness of the first clamp and the second clamp.

The interior six square tube hole dimensions of described first large one end of clamp width equal the size of six square bolt nuts, the manhole that first clamp width is little is greater than the engineering diameter of the first set bolt, described second clamp is identical with appearance and size with the first clamp structure, and the interior six square tube hole dimensions of the large one end of its width are different.

The lozenges structures slope angle of two featheredge edges that the square blind hole in described matrix two ends is relative is the twice at the angle of inclination of the first clamp two relative waists.

The utility model has the following advantages:

1. the utility model is novel unique, trapezoid appearance structure by the first clamp and the second clamp can meet the instructions for use of spanner, in addition utilize the design of rotatable Level Multiple Degree of Freedom Structures can realize the straight of lateral ends in use, avoid the injury of opponent in hand-held process to improve the comfort level of operation.

2. the utility model structure is simple, and easy to make, parts material is cheap, good manufacturability, and cost of manufacture is low, and application is wide.
