Description

Freely adjustable speeder wrench

Technical field

Freely adjustable speeder wrench described in the utility model, is related to a kind of hardware ＆ tools, is specially applied to outer The spanner that hex nut and bolt are tightened or loosened.

Background technology

In machine-building, maintenance process, spanner is essential hardware ＆ tools.Be presently used for outer-hexagonal nut and The spanner of bolt has two kinds of open-end wrench and shfting wrench.Wherein open-end wrench screw bolt and nut uniform force, makes using reliably It is preferable with effect, but the limitation of dimensions be present, the nut of different size just needs the open-end wrench of different size so that work Tool quantity is more, and cost increases.Shfting wrench is because movable head can be with folding, so adaptability is wider, one can twist shfting wrench Nuts and bolt that is tight or unclamping different size.Conventional shfting wrench has two, when folding it is inconvenient, it is necessary to by Thumb promotes worm screw, and so as to drive movable head folding, this mode is less efficient；Second, the turret head stress of nut, bolt is not It is good, because great gap be present in snail pavilion and rack, therefore in real work, nut, the stress of bolt not in hexagonal in front On, but on angle, workpiece can wear corner in loading process, destroy hexagonal configuration so that dismounting inconvenience from now on.

For it is above-mentioned the problems of in the prior art, research and design is a kind of new freely adjustable quick to pull Hand, it is the problems of in the prior art very necessary so as to overcome.

The content of the invention

In view of it is above-mentioned the problems of in the prior art, the purpose of this utility model be research and design it is a kind of it is new can Freely regulated speeder wrench.To solve present in prior art：

1st, open-end wrench is size-limited, it is necessary to prepare the spanner of all size, increases number of tools, improve use into This；

2nd, shfting wrench needs to drive the folding of movable head repeatedly when playing the part of bolt, nut, and service efficiency is relatively low；

3rd, due to gap existing for monkey wrench screw rod and rack so that monkey wrench oral area can cause hexagonal spiral shell in work The abrasion in bolt corner, the problems such as causing bolt and nut long-term use of.

Therefore it is a kind of folding with convenience, workpiece uniform force, safe to use and efficiency that the utility model is to be provided It is higher, can be according to the freely adjustable speeder wrench of the size adjust automatically opening of fastener turret head.

What technical solution of the present utility model was realized in：

Freely adjustable speeder wrench described in the utility model, it is characterised in that described freely adjustable quick Spanner includes：Wrench body A, wrench body B, sliding block and spring；

Wrench body A described in the utility model includes the handle A and driving end A being processed as one；Driving end A is in bilayer Hexagonal platy structure, six guide groove A being uniformly machined with driving end A centered on the center of circle；Uniform processing on driving end A There is at least three connecting hole A；It is driving end B slots between two layers of driving end A；Spring mounting hole is machined with the inside of handle A；

Wrench body B described in the utility model includes the handle B and driving end B being processed as one；Driving end B is O-shaped plate Shape structure, six guide groove B are uniformly machined with driving end B；Arc rivet groove is machined with every guide groove B sidepiece； At least three connection slotted eye is uniformly machined with driving end B；Spring mounting hole is machined with the inside of handle B；

Sliding block described in the utility model is U-shape structure, and connecting hole B is machined with its openend；

Driving end B described in the utility model is inserted into driving end A driving end B slots；Connecting hole A is with being connected slotted eye It is corresponding, it is connected by rivet A；The U type slot of sliding block is outwards inserted into leading for coincidence by driving end A and driving end B inner rings Into groove A and guide groove B so that connecting hole B and arc rivet groove coincide, and are connected by rivet B；Insert at the both ends of spring Enter into the spring mounting hole on the inside of handle A and handle B.

The radian of arc rivet groove described in the utility model is outwards deployed along clockwise direction by the center of circle.

Wrench body A described in the utility model and wrench body B are in open configuration under the action of the spring, during open configuration Sliding block is in slideway top；Handle A merges compression spring with handle B；Arcuately rivet groove moves sliding block to the center of circle.

Occupation mode of the present utility model is fairly simple easy to operate；Concrete mode is：

Driving end circular hole of the present utility model is set on outer-hexagonal nut or bolt head, two handles are clenched with hand, Close up two handles, driving end A and driving end B make counterclockwise and clockwise movement respectively, sliding block guide groove guiding and Moved in the presence of arc rivet groove to center, form an interior hexagon and clamp outer-hexagonal nut or bolt, rotary handle Realize the action tightened or unclamped to nut or bolt；

After release is turned, release handle, two handles are set back under tension force of spring promotion, and sliding block is being led It is displaced outwardly in the presence of guiding and arc rivet groove to groove, is separated with outer-hexagonal nut or bolt；

Above-mentioned two step can complete the work of fastening and the release of whole nut or bolt repeatedly.

The utility model has the advantages that it will be apparent that it is mainly manifested in：

1st, the utility model is provided with clamps outer-hexagonal nut or bolt using sliding block, suitable for plurality of specifications nut and spiral shell The use of bolt, saves cost；

2nd, the utility model is provided with six sliding blocks, it is ensured that six face uniform forces of outer-hexagonal nut or bolt；

3rd, the utility model is provided with six sliding blocks, it is ensured that will not destroy outer-hexagonal nut or bolt surface knot when in use Structure, the service life of screw bolt and nut will not be reduced.

The utility model has structure novelty, simple processing, easy to use, operating efficiency is high, reduces use cost, safety The advantages that reliable, its high-volume, which puts goods on the market, will produce positive social benefit and significant economic benefit.
