Description

Detachable multifunctional anti-collision file

Technical Field

The utility model belongs to the technical field of manufacturing of technological equipment, and relates to a multifunctional file with detachable and anti-collision functions.

Background

The surface of the file is provided with a plurality of fine and dense cutter teeth and strips for manually filing workpieces. The file is divided into a flat file (a flat file), a square file, a semicircular file, a circular file, a triangular file, a rhombic file, a knife file and the like according to the shape of a section. Wherein, the flat file is used for a plane, an outer circular surface and a convex cambered surface; the square file is used for a square hole, a rectangular hole and a narrow plane; the triangular file is used for inner angles and planes; the semicircular file is used for concave cambered surfaces and planes; the round file is used for round holes, concave cambered surfaces with smaller radiuses and elliptical surfaces. The thickness of the file teeth is selected according to the processing precision, a thin-tooth file is selected if the processing precision is high, and a thick-tooth file is selected otherwise. Because the files used in different occasions have different shapes, tooth thicknesses and specifications, each file needs to be independently configured when a workpiece is processed.

The traditional file is composed of a cutter body and a handle, in the using process, the teeth of the file on the surface can lose effectiveness due to abrasion, but the handle is relatively small in abrasion and not easy to damage, so that the waste of resources and the increase of cost can be caused by abandoning the whole file.

When the file is used, an operator needs to hold the knife handle in one hand and restrain the front end of the knife body in the other hand to master the motion track and the filing strength of the file, and if a workpiece is a thin metal plate and is filed aiming at the cross section of the workpiece, the hand holding the knife handle is often touched on the cross section of the steel plate due to excessive force or inattention caused by the fact that a baffle plate for protecting the hand is not arranged at the knife handle end of the traditional file, and therefore bruise or bruise is caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a detachable multifunctional anti-collision file, which reduces the cost and saves resources by using a replaceable cutter body; files with different shapes, different tooth thicknesses or different specifications are assembled according to the profile shape of a filed workpiece, convenience is provided for an operator, and the workpiece processing period is shortened; and the handle of a knife that sets up anticollision baffle is used, avoids operator to bump injury or scotch the hand in the course of working.

In order to achieve the purpose, the scheme of the utility model is as follows:

a detachable multifunctional anti-collision file comprises a mixed file body and a handle 7.

The mixed file cutter body consists of cutter bodies with different shapes and specifications; the cutter body includes filing face and screw 2, connects through the screw thread, realizes dismantling and replaces the cutter body.

And the handle 7 is provided with a nut 4 matched with the mixed file cutter body and is in threaded connection with the mixed file cutter body. The handle 7 is provided with an anti-collision baffle 5 at the position connected with the mixing file body, and the anti-collision baffle 5 is a circular metal plate with the diameter of 6cm and is used for protecting hands. The handle 7 is made of rubber, and is provided with an anti-skidding groove 8 and a through hole 6 for hanging. When the cutter body is replaced, the new cutter body is also provided with a screw and matched with the nut on the handle.

Further, the mixing file body comprises two cutter bodies with different shapes and specifications; wherein, the end cutter body is provided with a filing surface and a screw, the middle cutter body is provided with a filing surface, a nut matched with the end cutter body and a screw connected with the handle 7, and the filing surface, the nut and the screw are all tightly connected through threads.

The utility model has the beneficial effects that:

(1) the cutter body of the file is a mixed file body consisting of cutter bodies with different shapes and specifications, so that files with different section shapes can be prevented from being repeatedly replaced when a plurality of section-shaped workpieces are filed, and the processing period is shortened; meanwhile, the handle is an independent part, so that a new cutter body can be replaced after the file surface is damaged, the whole file does not need to be discarded, resources are saved, the cost is reduced, and the novel file is more environment-friendly.

(2) The anti-collision baffle with the diameter of 6cm is arranged at the position where the handle is connected with the mixing file body, so that the scratch caused by the contact of the hand and the cross section when the cross section of a thin metal plate workpiece is filed can be avoided, and the safety of the file is improved.

(3) The handle is made of rubber materials, the anti-skidding groove is formed in the handle, the through hole is formed in the handle, the handle is convenient to carry and hang, and the usability of the file is improved.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

In the figure: 1, round files; 2, screwing; 3, a flat file; 4, a nut; 5, an anti-collision baffle; 6 through holes; 7, a handle; 8 anti-slip grooves.

Detailed Description

The following further describes a specific embodiment of the present invention with reference to the drawings and technical solutions.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention. The utility model provides a detachable multifunctional anti-collision file which comprises a mixed file body and a handle 7.

The mixed file cutter body is formed by tightly connecting cutter bodies with different shapes and specifications through threads; and is tightly connected with the handle 7 through screw threads. Wherein the cutter body is respectively a round file 1 and a flat file 3 which are connected with a nut through a screw; the flat file 3 and the handle 7 are connected with a nut through screws to form a complete detachable multifunctional anti-collision file. The cutter body can be replaced according to different filing profiles, and the cutter body is independently discarded when the filing surface is damaged.
