Abstract
The invention discloses a detachable file capable of being held with both hands. The detachable file comprises a file body and handles and further comprises a shell. A dovetail groove penetrating through the shell is formed in the shell. A strip-shaped protrusion matched with the dovetail groove is formed in the file body. The number of the handle is two, and the two handles are arranged on the two sides of the shell respectively in the axis direction of the file body. By the adoption of the detachable file capable of being held with both hands, the problems that in the prior art, a file body of a file cannot be replaced, and the file is only provided with one handle are solved; the file body of the detachable file can be replaced conveniently, and the detachable file can be held with both hands.
Description
Technical field
The present invention relates to filing field of tool, specifically relate to a kind of detachable file of hands grasping.
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.
Summary of the invention
The object of the present invention is to provide a kind of detachable file of hands grasping, solve 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 present invention is achieved through the following technical solutions:
A detachable file for hands grasping, comprises cutter hub, handle, also comprises housing, and 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 invention provides 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 present invention 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 present invention 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 present invention, 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 present invention 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 present invention's specific embodiment.
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 object, technical solutions and advantages of the present invention, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, and exemplary embodiment of the present invention and explanation thereof are only for explaining the present invention, not as a limitation of the invention.
Embodiment 1:
The detachable file of a kind of hands grasping as shown in Figure 1, comprises cutter hub 1, handle 2, housing 3, and 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 present invention 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.Meanwhile, the present invention is provided with former and later two handles 2, and 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 detachable file for hands grasping, 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.
