Abstract

The utility model discloses a high-efficient wrench which is suitable for disassembling and assembling equipment. The high-efficient wrench is composed of the main parts such as a handle (1), a quincunx inner sleeve (2), a cover ring (3), a locking pin (5), etc. The quincunx inner sleeve (2) can freely rotate in the circular hole of the handle (1), a pulling function can be obtained via the locking pin matching with the outer teeth of the inner sleeve, the quincunx inner sleeve (2) can slide inversely, and thus continuous and quick operation is realized. The complex operating process of a general wrench is avoided, the trouble that socket wrenches need to replace gloves is eliminated, and the high-efficient wrench can be used in the situation that the socket wrenches can not be used. The high-efficient wrench has the advantages of high work efficiency, flexible use and wide application range, the high-efficient wrench can be used forwards and inversely for obtaining the function of disassembly or assembly.

Description

High-efficient wrench

The utility model is a kind of efficient spanner that the equipment dismounting is used that is suitable for.

The spanner of being used always at present has box spanner, double offset ring spanner, open-end wrench etc.As box spanner it by three supporting compositions of sleeve, handle, latch, appoint to lack one, all can not use, and they are separation members, be not easy to use and take care of.When by the bolt axial space of dismounting when narrower, box spanner just can't enter use, and bad adaptability is because above-mentioned deficiency causes the box spanner scope of application to be restricted.Double offset ring spanner, open-end wrench and other manual wrench all need pass through insertion → switching → extract → insert again during use ... such cover operating process, formality is loaded down with trivial details, when around the assembling-disassembling bolt other members being arranged, then more frequent, therefore, this is the maximum weak point of spanner commonly used.

The utility model has designed a kind of efficient spanner, it has eliminated above-mentioned cumbersome operation sequence, can pull nut continuously apace after once inserting, till tightening or unclamping, improve work efficiency greatly, and can adapt to the little place of axial space, wide accommodation, easy to use, real is desirable efficient spanner.

This efficient spanner is made of cover (2), bezel ring, (3), fixture (4), lock pin (5), spring (6) and plug (7) in handle (1), the plum blossom.Cover (2) is fixing with fixture (4) with bezel ring, (3) in the plum blossom, make it free to rotate in the circular hole of handle (1), the external tooth of cover (2) cooperatively interacts in lock pin (5) and the plum blossom, and cover (2) both can have been felt relieved pull, but reverse slide and constitute efficient spanner again.

Have 16 sawtooth around the cylindrical of cover (2) in the plum blossom, have 12 plum blossom teeth on the inner periphery, it can match with square nut or hexagonal (hexagon)nut, uniform four holes of And.According to the across flats's of hexagonal (hexagon)nut different size, can be made into the efficient spanner of all size model.Use in this spanner front, realizes the function of dress, and reverse side uses, the function that realization is torn open, applying flexible.The minimum angles that handle is pulled is 1/16 circle, just can realize the dismounting effect, and the maximum angle that handle is pulled is unrestricted.Spanner is positive when using, and pulls forward, and lock pin (5) pins and is fastening nut, pulls backward, and lock pin (5) is out of stock and slide, and makes the handle angle that dallies, and continued operation so repeatedly can realize last jack panel rapidly and efficiently.Efficient spanner is made with cast steel or tool steel or powder metallurgy.

This efficient spanner has applying flexible, and operation is easy characteristics continuously, wide accommodation, and high efficiency can positive and negatively be used, with the effect that reaches dress or tear open.Simple in structure, make simple and easy, long service life.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

Fig. 1 is efficient spanner A-A topology view.

Fig. 2 is efficient spanner structure figure (this figure make an abstract accompanying drawing).

(1) is that handle (5) is a lock pin among the figure

(2) be that cover (6) is spring in the plum blossom

(3) be that bezel ring, (7) is a plug

(4) be fixture

With reference to Fig. 2, handle (1) is made for cast steel, and an end is circular, and have a circular hole, and match with cover (2) in the plum blossom, the assembling slotted eye of lock pin (5) is arranged on it, the other end is the microscler handle of shaking hands, it is two-sided all do fluted, to save steel and weight reduction.Cover (2) is made with cast steel or powder metallurgy in the plum blossom, has 16 sawtooth on its excircle, has 12 plum blossom teeth on the inner periphery, can match with square nut and hexagonal (hexagon)nut.Cover (2) is fixing with 4 fixtures (4) with bezel ring, (3) in the plum blossom, this fixture (4) can be with rivet or screw, the interior cover of whole plum blossom (2) can freely be rotated in the circular hole of handle (1), lock pin (5) is made four prism type with cast steel, be installed in the assembling slotted eye of handle, its tapered end just in time matches with the external tooth of cover (2) in the plum blossom, in plum blossom on the thickness direction of cover (2) and equip two lock pins (5), be separated by with thin-walled between the two, and a spring (6) and a plug (7) respectively are housed, made efficient spanner like this.

Claims

1, a kind ofly is suitable for the efficient spanner that the equipment dismounting is used, it is characterized in that it is made of cover (2), bezel ring, (3), fixture (4), lock pin (5), spring (6) and plug (7) in handle (1), the plum blossom, cover (2) is fixing with fixture (4) with bezel ring, (3) in the plum blossom, make it free to rotate in handle (1) circular hole, lock pin (5) cooperatively interacts with the external tooth of the interior cover of plum blossom (2), the interior cover of plum blossom (2) both can have been felt relieved pull, slidably constitute efficient spanner again.

2, efficient spanner according to claim 1, an end that it is characterized in that handle (1) be for circular, and have a circular hole and cooperates with cover (2) in the plum blossom, and the assembling slotted eye of lock pin (5) is arranged on it, and holding in addition is the microscler handle of shaking hands, it is two-sided all do fluted.

3, efficient spanner according to claim 1 is characterized in that having 16 sawtooth on the excircle of cover (2) in the plum blossom, has 12 plum blossom teeth on the inner periphery, can match with square nut or hexagonal (hexagon)nut, and uniform four holes.
