An object of the utility model is to provide a file convenient to change cutter body, solve prior art in the file can't change the cutter body and the file only has the problem of a handle, realize the purpose that convenient change file cutter body, while can dual tactics grip.
Description
Technical field
The utility model relates to filing field of tool, specifically relates to a kind of file being convenient to change cutter hub.
Background technology
File, has many fine and closely woven cutters tooth, bar shaped on the surface, is the instrument in order to carry out filing to workpiece, and can do trace processing to top layers such as metal, timber, leathers, be requisite instrument in component of machine process.File divides by section shape flat file (flat file), square file, half-round file, round file, triangular file, rhombus file and featheredge file etc.Flat file is used for filing face, periphery and convex globoidal; Square file is used for filing square hole, oblong aperture and narrow plane; Triangular file is used for filing interior angle, delthyrium and plane; Half-round file is used for filing cancave cambered surface and plane; Round file is used for filing the less cancave cambered surface of circular hole, radius and ellipsoid.Because different occasions needs to use difform file, often kind of file is all independently arranged, and it is for subsequent use that workpeople usually needs to be equipped with many dissimilar files; And once file lost efficacy because of wearing and tearing, by whole, file must be discarded, cause increasing of the waste of resource and cost.
In addition, file conventional at present is generally made up of cutter hub and handle, handle is installed on the tongue end of file, common handle contours is generally long egg type or is with fusiform elongated cylinder etc., and handle quantity has and only has one, such handle in actual applications, defensive position gripping handles, and front palm needs to be placed on balance and the dynamics that file is grasped in file front end, can directly contact with the file cutter hub of steel, easily occur that palm grinds the phenomenon of bubble, not only the health of user is damaged, increase labour intensity, and operating efficiency and working effect can be made to have a greatly reduced quality.
Utility model content
The purpose of this utility model is to provide a kind of file being convenient to change cutter hub, solves file in prior art and cannot change cutter hub and file only has the problem of a handle, realize changing easily file cutter hub, simultaneously can the object that grips of two hands.
The utility model is achieved through the following technical solutions:
Be convenient to the file changing cutter hub, comprise cutter hub, handle, also comprise housing, described housing is provided with through dovetail groove, described cutter hub is provided with the strip bulge matched with described dovetail groove; Described handle has two, along the axis direction of described cutter hub, is separately positioned on the both sides of described housing.For existing file cutter hub and handle is non-dismountable and before easily causing user, palm weares and teares situation, the utility model provide a kind of can the file of dismounting cutter hub efficiently, and this file is with former and later two handles, thus realize protecting while right-hand man, avoid front palm and cutter hub when conventional file uses and directly contact the injured problem of the easy wearing and tearing that cause.The utility model is provided with through dovetail groove on housing, and on described cutter hub, be provided with the strip bulge matched with described dovetail groove, described strip bulge is then free to pass in and out from the side of described dovetail groove, complete the installation and removal of cutter hub, thus conveniently change cutter hub, realize the object of different workpieces being carried out to filing.Meanwhile, the utility model is provided with former and later two handles, and user all can hold handle by two hands, thus avoids traditional file and need front palm to be placed on file front end and grasp the balance of file and the problem of dynamics, alleviates and weares and teares to the hand of user.
Further, described handle is connected with described housing by screw thread.Handle is not wearing terrain, be not easy impaired under normal usage, but under special circumstances, if handle damages, traditional file then cannot continue to use, so handle is set to removable state by screw thread by the utility model, is convenient to change it when handle is impaired, avoids causing scrapping of whole file.
Further, described handle is coated with linen-cotton cloth.The hand avoiding user by linen-cotton cloth directly and handle contact, utilizes the characteristic that linen-cotton cloth matter is soft, increases buffering, alleviate the friction of filing process to user's hand further.
To sum up, the utility model has following beneficial effect:
By the dovetail groove that matches each other and strip bulge, realize file cutter hub disassembling, assembling and replacing easily; By former and later two handles, realize two palms in filing process and all can grip, avoid front palm to be placed directly in file front end and cause scratch.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the structural representation of another specific embodiment of the utility model.
Numbering in figure is followed successively by: 1-cutter hub, 2-handle, 3-housing, 4-dovetail groove, 5-strip bulge.
Detailed description of the invention
Clearly understand for making the purpose of this utility model, technical scheme and advantage, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, exemplary embodiment of the present utility model and explanation thereof are only for explaining the utility model, and conduct is not to restriction of the present utility model.
Embodiment 1:
A kind of file being convenient to replacing cutter hub as shown in Figure 1, comprises cutter hub 1, handle 2, housing 3, described housing 3 is provided with through dovetail groove 4, described cutter hub 1 is provided with the strip bulge 5 matched with described dovetail groove 4; Described handle 2 has two, and along the axis direction of described cutter hub 1, be separately positioned on the both sides of described housing 3, described handle 2 is connected with described housing 1 by screw thread.The utility model is provided with through dovetail groove 4 on housing 3, and on described cutter hub 1, be provided with the strip bulge 5 matched with described dovetail groove 4, described strip bulge 5 is free to pass in and out from the side of described dovetail groove 4, complete the installation and removal of cutter hub 1, thus conveniently change cutter hub 1, realize the object of different workpieces being carried out to filing.Simultaneously, the utility model is provided with former and later two handles 2, user can hold handle 2 by two hands simultaneously, thus avoids traditional file and need front palm to be placed on file front end and grasp the balance of file and the problem of dynamics, alleviates and weares and teares to the hand of user.In addition, because handle 2 is not wearing terrain, not easily damaged under normal usage.But under special circumstances, if handle 2 damages, traditional file then cannot continue to use, so the present embodiment is threaded connection described handle 2 and housing 3, is convenient to change it when handle 2 is impaired, avoid causing scrapping of whole file because handle damages.
Embodiment 2:
A kind of file being convenient to replacing cutter hub as shown in Figure 2, on the basis of embodiment 1, described handle 2 is coated with linen-cotton cloth.Because linen-cotton cloth has soft, that matter is soft characteristic, the hand of user can be avoided directly to contact with handle 2 by linen-cotton cloth, increase buffering, alleviate the friction to user's hand in filing process further.
