Abstract

The present invention relates to a hand grinder auxiliary device enabling a straight cut by connecting a separate auxiliary device to a hand grinder. By dividing each portion, a base bracket (10) connected to the hand grinder and a length adjustment plate (20) in an insertion space (12) inside the base bracket (10) are coupled to be moved from side to side to enable a length to be adjusted. Up and down thickness adjustment bundles (30a, 30b) are vertically moved in a vertical plate (20b) and flexibly moved in accordance with a thickness of a material to establish a guideline in accordance with a material having a different thickness. After fixating a material with the length adjustment plate (20) up to a desired length to be cut and then fixating the material with the up and down thickness adjustment bundles (30a, 30b) to be fitted to the material; the material is cut along the guideline to enable a straight cut.

Description

Technical Field [0001] The present invention relates to a hand grinder auxiliary apparatus for straight cutting,

The present invention relates to a hand grinder assisting apparatus capable of cutting a straight line, and more particularly, by providing an insertion space inside a base bracket, a length adjusting plate is moved left and right to cut a material into a desired length, It can be used for various materials by forming a guideline for fixing and material cutting according to the thickness of the desired material with the upper and lower thickness adjusting rollers at the lower end of the length adjusting plate. It is characterized in that a hand grinder auxiliary device .

Generally, when a straight cut is made using a hand grinder, an operator draws a piece of gold on the material and cuts the piece along the gold. In general, it is difficult to cut a straight line with a human hand about cutting a straight line. When the cutting is not performed in one operation, when the rework is performed, the blade is caught by the material and the broken blade rises, There is also the risk of.

Therefore, an improved hand grinder is known in Japanese Patent Application Laid-Open Publication No. 2002-229902. The structure of the hand grinder includes a rotating base body 100 coupled to the outer peripheral surface of the driving motor housing 302 as shown in FIG. 1, A driving unit 300 composed of a head coupling unit 304 and a driving motor gear 305 coupled to the driving motor housing 302 and a rotary cutting unit 500 coupled to the head coupling unit 304 of the driving unit 300 A cutter gear 505 to be sequentially attached to the cutter base 503 and the cutter base 503, a cutter handle 502 to which a drive motor on / off switch 303 is attached, a cutter 501, a safety cover 504 And a rotary cutting part 500 constituted by the coupling parts of the elements. However, the hand grinder having the above-described structure has a complicated structure and inconvenient cutting work.

Patent Document 1: Korean Patent Laid-Open Publication No. 10-2011-0066998 (circular hollow pipe type rectangular pipe cutting device using a hand grinder)

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a cutting apparatus capable of cutting a straight line by a person's hand without the aid of another machine, The present invention provides a hand grinder auxiliary device for a hand grinder.

According to an aspect of the present invention,

Wherein the hand grinder head portion is detachable through a base bracket 10 in which an insertion space 12 is formed in the base bracket 10 and a removable hole 11 in the base bracket 10, The grinder auxiliary device is used as a task solution means.

The base bracket 10 has an insertion space 12 for inserting the length adjusting plate 20 into the base bracket 10. The length adjusting plate 20 is inserted into the insertion space 12, And the stopper 40 can be fastened to adjust the cutting length,

The length adjusting plate 20 is formed in a lattice shape and the horizontal plate 20a is inserted into the insertion space 12 formed in the base bracket 10 to adjust the cutting length and the vertical plate 20b Is positioned at the upper and lower thickness adjusting bundles 30a and 30b and can be fixedly coupled to the thickness of the material to be cut by being fluidly coupled.

The upper and lower thickness adjusting bundles 30a and 30b are located on the vertical plate 20b so that both of the upper and lower adjusting bundles can be moved upward and downward and fixed by the stop bolt 40. [ So that it can be used for various material thicknesses.

In general, it is difficult to cut a straight line with a human hand about cutting a straight line. When the cutting is not performed in one operation, when the rework is performed, the blade is caught by the material and the broken blade splashes, There is also the risk of.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a new straight cutting assist device capable of accurately performing straight cutting without the help of other mechanical devices, The purpose is to provide.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a conventional hand line. FIG.
2 is a view for explaining a hand grinder equipped with a linear cutting assistant device according to the present invention.
3 is a view for explaining an example in which only a straight cutting assistant device is assembled to a hand grinder according to the present invention.
4 is a view for explaining a portion where a length adjusting plate is assembled to a base bracket in a hand grinder according to the present invention;
FIG. 5 is a view for explaining a removable hole for mounting to a hand grinder head according to the present invention; FIG.
6 is a view for explaining the upper and lower thickness adjusting bundles in detail in the hand grinder according to the present invention.

Hereinafter, a hand grinder assisting apparatus capable of cutting a straight line according to the present invention will be described in detail with reference to FIGS. 2 to 6, and elements having the same functions in FIGS. 2 to 6 are denoted by the same reference numerals . In the drawings, the constituent elements and operations and effects which are easily known from the related art will be briefly or omitted, and the related parts are mainly shown.

2, a base bracket 10 having an insertion space 12 formed therein and a mounting hole 11 formed in the base bracket 10 are mounted on a head of a conventional hand grinder, And is capable of being freely detached from the hand grinder head.
