Abstract
A 3D-printed wrench comprises a wrench handle and a wrench head. The wrench handle and the wrench head are arranged in a split mode and connected detachably through a connecting structure. The wrench head is formed through 3D printing and provided with a working cavity capable of being matched with a workpiece. The wrench handle and the wrench head are arranged in the split mode and connected detachably. According to actual requirements, wrench heads of different types can be manufactured through 3D printing. The wrench heads of different types correspond to the universal wrench handle, so that printing materials are greatly saved, and printing time is greatly shortened; moreover, the 3D-printed wrench has the advantages of being high in dismounting and mounting speed and convenient to use.

Detailed description of the invention
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearer, with
Lower combination drawings and Examples, are further elaborated to the present invention.Should be appreciated that described herein
Specific embodiment only in order to explain the present invention, be not intended to limit the present invention.
Referring to figs. 1 through Fig. 3, the invention provides a kind of 3D and print spanner, including spanner handle 1 and driving end 2,
Spanner handle 1 and driving end 2 are arranged for split, and spanner handle 1 includes handle 11 and is arranged on handle 11 head end
Handle union joint 12, described driving end 2 also includes key adaptor 13, and described key adaptor 13 can be with handle
Hands union joint 12 by snapping connection, draw-in groove connect or/and realize by the way of threaded removably connecting.Pull
Being printed by 3D at hand and generate, described driving end 2 is provided with can be with the working cavity of work pieces mate.According to reality
Border conditions of demand, can go out the driving end of different model by 3D printing and making.The driving end of different model is corresponding
General spanner handle, is so greatly saved printed material and time-write interval, key adaptor and handle even
Joint uses the mode of removably connecting to connect, and therefore the present invention also has dismounting speed soon, and easy to use is excellent
Point.
The fixing connection of mode of welding is used with reference to Fig. 2, handle 11 and handle union joint 12.Handle 11 is hollow
Handle, hollow handle is made up of hollow stainless steel tube, lighter in weight, is hardly damaged.Spanner in the present invention
Handle can as general handle, handle can the driving end of corresponding multiple different model, significantly subtract
Lack part to be printed, save printed material and time-write interval.
With reference to Fig. 2 and Fig. 3, the one side of described key adaptor 13 is provided with at least one boss 22, described
The groove 121 that can accommodate and engage boss 22 it is correspondingly arranged on handle union joint 12.Boss in the present embodiment
22 is one and for tetragon boss, groove 121 correspondence be also one and same be tetragon groove.Boss
The periphery of 22 is provided with multiple M4 screwed hole 23, and the peripheral correspondence position of groove 121 is provided with M4 screwed hole 23,
Boss be engaged to correspondence groove after by the spacing fastening of multiple bolts.Such connected mode, has peace
Dress is convenient, the advantage that bonding strength is high.
With reference to Fig. 1 and Fig. 3, the driving end 2 of the present invention is provided with reinforcement structure, and described reinforcement structure is for being arranged on
The reinforcing plate 21 of working cavity one side, described reinforcing plate 21 is arranged in the vertical direction that spanner is turned round.With
Common metal Wrench head is compared, and the driving end 2 of the present invention uses 3D to print and manufactures, and only needs one and beats
Print machine can obtain the spanner of any model under the complex environments such as field, and convenient processing and manufacture is flexible.With existing
Some monoblock type prototypes print spanner and compare, and the present invention only has driving end 2 to use 3D to print, simultaneously to printing
Technological parameter is optimized, and is provided with strengthening plate 21, intensity relatively monoblock type in the vertical direction that spanner is turned round
Prototype prints spanner and wants height.
Further, reinforcing plate 21 of the present invention various informative, can be at the base of the bulk strength improving spanner
On plinth, it is achieved save printed material and time-write interval, and ensure the globality of product and attractive in appearance.Additionally originally
The plateau form of invention is also not necessarily limited to tetragon, it is also possible to for round boss, polygon boss, oval convex
Platform or figure of eight boss, the geomery of described groove adapts with boss.On the one hand can realize individual
Property customization, on the other hand boss has multiple corner and so enables to spanner handle 1 and driving end 2 can obtain
To more preferable spacing fixing.
With reference to Fig. 4, give the driving end of a kind of form.Its working cavity one side it is arranged on driving end 2
Reinforcing plate 21 be two pieces.Two pieces of reinforcing plates 21 are separated by a distance to be arranged in parallel, outside working cavity
The outer side edges outer side edges corresponding with on driving end of reinforcing plate 21 flush.Two pieces of reinforcing plates are pulled in raising
On the basis of the bulk strength of hands, it is achieved save printed material and the purpose of time-write interval.Two pieces of reinforcing plates
Bottom surface flushes with the bottom surface of driving end so that driving end entirety is more aesthetically pleasing.
With reference to Fig. 5, giving the driving end of a kind of form, the boss 22 that key adaptor is arranged is polygon
Boss.The reinforcing plate 21 being arranged on its working cavity one side on driving end 2 is outside from the inner side of working cavity
Extension forms.The outward extending outer side edges of reinforcing plate 21 is corresponding outer side edges less than on driving end, is improving
On the basis of the bulk strength of spanner, it is achieved save printed material and the purpose of time-write interval.Same reinforcement
The bottom surface of plate flushes with the bottom surface of driving end.
Fig. 6 and Fig. 7, give also the driving end of multi-form.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to
Stating embodiment, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.Should carry
Go out, for those skilled in the art, improvement without departing from the principles of the present invention
And retouching, these improvements and modifications also should be regarded as protection scope of the present invention.
