Embodiment Construction

[0023] Saw blade is the most commonly used and most effective tool for sawing workpieces in manual fitter work. It has been widely used since the beginning of woodworking in human history, and then developed to sawing and cutting metal and other materials. Operation. The efficient cutting performance of the saw blade on the material lies in the fact that its sharp saw teeth arranged in rows can smoothly cut into the middle of the material tissue, so the characteristic of the manual saw blade is that it can smoothly cut into the soft material under a small pressure for cutting operations .

[0024] When using a file for manual fitter work to file a plane, it is usually difficult to file soft metal materials such as aluminum and copper, because this type of material is soft and difficult to use with a file The debris from the file is easy to deform and embedded in the dense gap between the teeth of the file. A large amount of debris embedded in the middle of the file will serio...

Abstract

The invention relates to a file used by a fitter for manual operation, in particular to a file which has a special structure, adopts the combination of saw blades and a main file body, and is capable of filing soft materials such as aluminum, copper and plastics. The file for soft materials consists of basic parts such as a file handle, an alary nut, a saw blade tightening slider, a saw blade tightening rod, saw blades and the main file body. According to the file for soft materials, the characteristic that a saw blade cannot be sticky to cuttings easily in the cutting process is utilized, a plurality of saw blades are arrayed in parallel and fixedly arranged in one manual fixture, so that a novel file for soft materials is constituted, the file for soft materials not only can be cut into a workpiece easily when cutting soft materials, but also can not be sticky to cuttings in the cutting process, so that the operation efficiency of manual filing is greatly improved. The saw blade tightening rod is inserted into holes in the two sides of the saw blade tightening slider, the saw blade tightening slider can pull the saw blade tightening rod outwards in the process of tightening the alary nut, so that the saw blades inserted into the rectangular empty slots of the main file body are tightened, and the workpiece can be filed conveniently.

Description

Technical field: [0001] The invention relates to a file used by fitters for manual work, in particular to a file with a special structure that can easily file soft materials such as aluminum, copper, and plastics by combining a saw blade with a file body. [0002] The invention utilizes the feature that the saw blades are not easy to stick chips when cutting, arranges several saw blades in parallel and fixes them in a manual fixture to form a novel soft material filing tool, which is easy to cut when cutting soft materials It is easy to cut into the workpiece when the material is cut, and it will not stick to the chips during the cutting process, which greatly improves the work efficiency of manual filing. Background technique: [0003] Usually for the convenience of filing soft materials, the traditional lath-shaped file is only made into a large arc tooth shape to facilitate cleaning of soft material chips embedded in the alveolar, but the large arc tooth shape lengthens t...
