The invention can quickly lock the inserted files of different models, and has the advantages of firm clamping, convenient carrying, high safety, simple structure, material saving and low cost.
Description
Technical field
The present invention relates to hand tools technical field, more particularly to a kind of multi-purpose self-locking Handle of file.
Background technology
Through commonly used instrument, including a variety of section configurations and size model number when file is polishing finishing object, during use
The file of different model is selected according to the situation of processed object surface, the rear portion of most files is provided with rectangle rectangular pyramid structure
File handle, file handle is inserted into wooden Handle of file or reassembling type Handle of file during use, wooden Handle of file is transported in high speed
Easily slipped and fallen off in the course of work turned, and waste of materials, there is complicated, easy pine for reassembling type Handle of file
Dynamic, cost height, dismount the shortcomings of inconvenient.In consideration of it, it is necessary that provide a kind of new Handle of file asks to solve above-mentioned technology
Topic.
The content of the invention
Technical problem solved by the invention is to provide a kind of multi-purpose self-locking Handle of file, its with file is supporting makes
With, can be firm with clip by the file quick locking of the different model of insertion, it is easy to carry, it is safe, it is simple in construction,
Save material, the advantages of cost is low.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of multi-purpose self-locking Handle of file, it is special
Sign is：By handle body and being formed from lock tube core for handle body front end is installed on, handle body center is provided with file delthyrium,
It is described to be fixed on file delthyrium front end from lock tube core, it is cylindrical metal pipe from lock tube core, before the inwall of cylindrical metal pipe is
Small stepped of the big back end inside diameter of internal diameter is held, the surface of stepwise interior wall is provided with spiral screw thread, and the spiral screw thread is high rigidity
The knife-edge that steel make, the circular die of processing excircles screw thread can be played a part of.
Compared with prior art, multi-purpose self-locking Handle of file of the present invention, when inserting file handle, the rotation of file handle side
Side is inserted, and utilizes the corner angle from the spiral screw thread on lock tube core stepwise interior wall to the rectangle rectangular pyramid bodily form Handle of file of insertion
The action of similar mantle fiber is carried out, the corner angle of Handle of file is embedded in spiral screw thread, file handle forms similar screw with from lock tube core
With combining closely for nut, the rectangular pyramid structure of file handle is adapted to from lock tube core stepwise interior wall, it can be realized
Forward and backward Multi-point fastening, clamp more firm and easy to process, low manufacture cost.
Brief description of the drawings
Fig. 1 is the structure schematic diagram of multi-purpose self-locking Handle of file of the present invention.
Fig. 2 is the working state schematic representation of multi-purpose self-locking Handle of file of the present invention.
Corresponding component names are in figure：1 handle body, 2 file delthyriums, 3 are from lock tube core, 31 spiral screw threads, 10 files
Handle, 100 files.
Embodiment
Refer to shown in Fig. 1 to Fig. 2, the present invention provides a kind of multi-purpose self-locking Handle of file, by handle body 1 and installation
Formed in handle body front end from lock tube core 3, handle body center is provided with file delthyrium 2, described to be fixed on file from lock tube core 3
The front end of handle of a knife hole 2, is cylindrical metal pipe from lock tube core, and the inwall of cylindrical metal pipe is small for the big back end inside diameter of front inner diameter
Stepped, the surface of stepwise interior wall is provided with spiral screw thread 31, and the spiral screw thread is the knife-edge that high rigidity steel make, can
To play a part of the circular die of processing excircles screw thread.
Multi-purpose self-locking Handle of file based on said structure design, handle body 1 use plastic production, comfortable feel,
File delthyrium 2 can be with casting, and manufacture craft is simple, is made from lock tube core 3 for high rigidity steel, the file handle being rotatably inserted into
Corner angle the screw thread of embedded spiral screw thread is formed by the effect of spiral screw thread, file handle 10 from lock tube core 3 with being combined into one
Body.Such as need to change file, need to only reversely rotate and exit file handle 10, then be reloaded into new file handle.
It is described above, only it is highly preferred embodiment of the present invention, any formal limitation not is made to the present invention, appoints
What those skilled in the art, without departing from the scope of the technical proposal of the invention, using in the method for the disclosure above
Appearance makes many possible changes and modifications to technical solution of the present invention, belongs to the scope of claims protection.
