Problems solved by technology

[0004] The purpose of the present invention is to provide a detachable file held by both hands, which solves the problem that the file body cannot be replaced in the prior art, and the file has only one handle, and realizes the convenient replacement of the file body and can be held by both hands at the same time. Purpose
In view of the fact that the existing file body and handle are not detachable, and the user's front palm is likely to be worn, the present invention provides a file that can quickly disassemble the blade body, and the file has two handles at the front and rear, so that Realize simultaneous protection for left and right hands, avoiding the problem of easy wear and injury caused by direct contact between the front palm and the cutter body when using conventional files

Embodiment 1

[0015] Such as figure 1 A detachable file held by both hands is shown, including a cutter body 1, a handle 2, and a housing 3. The housing 3 is provided with a through dovetail groove 4, and the cutter body 1 is provided with a The dovetail groove 4 matches the bar-shaped protrusion 5; the handle 2 has two, and is arranged on both sides of the housing 3 along the axial direction of the cutter body 1, and the handle 2 is threaded with the The housing 1 is connected. The present invention is provided with through dovetail groove 4 on housing 3, and is provided with the bar-shaped protrusion 5 that matches with described dovetail groove 4 on described cutter body 1, and described bar-shaped protrusion 5 then can freely In and out from the side of the dovetail groove 4, the installation and disassembly of the cutter body 1 is completed, so that the cutter body 1 can be replaced conveniently and quickly, and the purpose of filing different workpieces can be achieved. At the same ...

Embodiment 2

[0017] A detachable file held by both hands, on the basis of Example 1, the handle 2 is covered with cotton cloth. Because the cotton and linen cloth is soft and soft, the user's hand can be prevented from directly contacting the handle 2 through the cotton and linen cloth, which increases the cushioning and further reduces the friction on the user's hand during the filing process.

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 [0001] The invention relates to the field of filing tools, in particular to a detachable file held by both hands. Background technique [0002] The file, with many fine teeth on the surface, is a strip-shaped tool used to file the workpiece. It can do micro-processing on the surface of metal, wood, leather, etc. It is an indispensable tool in the processing of mechanical parts. Files are divided into flat files (flat files), square files, semi-circular files, round files, triangular files, diamond-shaped files and knife-shaped files according to the cross-sectional shape. Flat files are used to file flat surfaces, outer round surfaces and convex arc surfaces; square files are used to file square holes, rectangular holes and narrow surfaces; triangular files are used to file inner corners, triangular holes and flat surfaces; semicircular files are used to file concave curved surfaces and flat surfaces; round files are used to file round holes, concave arcs an...
