BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a replaceable saw blade,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saw blade capable of partial cutting of a saw blade, and more particularly, to a saw blade having saw teeth formed on both sides thereof to form a beveled cutting line so that when the saw blade is dull or broken during use, The saw blade hooking portions at which the saw dust is attached and detached are formed at both ends of the saw blade so that the saw dust is assembled on the opposite side when the saw teeth are damaged near the saw dust so as to cut off the sawtooth portions so that the cutting operation can be performed efficiently To a replaceable saw blade.

Generally, a saw is combined with a saw blade having saw teeth formed on a saw blade provided with a saw blade coupling. Such saw blades are only one side of the saw, so that if one tooth of the saw tooth is broken during operation, the saw is caught by the saw at the edge of the broken saw tooth every time sawing is performed, There is a problem in that the cutting surface is not cleaned because it is not smoothly cut.

For the above reasons, workers in the field use the new saw blade to replace the saw blade because of the inefficiency of the work as a whole.

In order to solve the problem that the cost of the operation cost is increased due to the abandoned saw blade, Korean Utility Model Registration No. 20-0413237 has provided teeth on both sides so that one tooth is used and then the teeth are turned over, Cost savings and efficient use of resources.

However, in the above method, when one tooth of a tooth is broken, the other saw teeth are useless, but the saw tooth with the damaged saw tooth is turned over and the opposite saw tooth is used, so that the cost can not be reduced and the resource can not be used efficiently I was leaving a pity.

In order to solve the above-mentioned problems, the present invention provides a saw blade having saw teeth on both sides thereof so as to form a beveling line so that the saw blade is partially cut and separated, and the saw blade hooking portions are formed at both ends of the saw blade, And to provide a replaceable saw blade capable of partially cutting the saw blade so that the saw blade can be assembled on the opposite side when the blade is damaged and the saw blade portion can be cut and used.

In order to achieve the above object, according to the present invention, there is provided a saw blade having jaws on both sides thereof, and a saw blade having hooks attached to and detached from the jaws, wherein a plurality of oblique cutting lines are arranged on the outer surface of the saw blade, And the hooks are provided on both ends of the saw blade in one or a pair, respectively.

According to the present invention as described above, the inclined perforations and hooking portions are formed on both sides of the saw blade to disassemble and disassemble the handle on the opposite side when the teeth are damaged in the vicinity of the handle, so that the damaged teeth can be used. It is possible to reduce the cost of the system.

1 is a front view of the use state of the present invention
2 is an exemplary diagram illustrating an embodiment of the present invention.
3 is a sectional view taken along the line "AA" in Fig. 2
4 is an exemplary view in which the hooking portion is formed in a pair at one end of the saw blade.
Fig. 5 is an exemplary view in which hooking portions are formed one by one diagonally opposite to both ends of a saw blade. Fig.
Fig. 6 is an exemplary view in which a pair of hooks are formed at both ends of a saw blade.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as claimed. .

1 to 3, the present invention is characterized in that a saw blade 1 is provided on both sides and an outer surface of a saw blade 3, on which a hooking portion 2 that is detached and removed from the saw dust 5 is formed, (2) are provided on both ends of the saw blade (3) in a single or a pair, respectively, in the case where a plurality of oblique cutting lines (4) are arranged so as to be spaced apart from each other at a predetermined interval.
And the slant perforations 4 are formed by cutting grooves 4 '.

In the figure, reference numeral 6 denotes a saw blade connecting member, and reference numeral 7 denotes a fastening member.

In the case of performing the sawing operation according to the present invention constructed as described above, the saw blade 3 having the inclined cutting line 4 formed thereon is inserted into the saw blade connecting hole 6 of the saw blade 5 and the fastener 7 And then the fastener 7 is rotated to fix the saw blade 3 to the saw dust 5.

With the saw mounted as described above, the operator often saws the object to be cut, but the saw teeth 1 of the saw blade 3 often break down during the sawing operation.

In this case, the conventional worker discards the broken saw blade 3 and replaces it with the new saw blade 3, but the present invention is not limited to the case where the saw tooth 1 that has not been broken So that waste of the saw blade 3 is saved as much as possible and production cost is reduced.

In other words, the hooking portions 2 are formed in various ways so that the sawtooth 1 of the saw blade 3 remaining after the broken sawteeth 1 is removed by using the oblique cutting lines 4 to be the longest, thereby improving the efficiency of the sawing work There is.

Therefore, when the one saw tooth 1 is broken as shown in Fig. 2, the operator continues to work with the other saw tooth 1 by turning the saw blade 3 upside down, and when the other saw tooth 1 is broken, (1) by using a slant perforation line (4) formed on the saw blade (3) by selecting a section so as to leave a portion where the teeth (1) The saw blade F having the untreated saw teeth 1 is discarded and sawing is continued using the saw blade G including the unbroken saw teeth 1. [

4 shows that the hook portions 2 are provided in pairs on the side of one end of the saw blade 3 on which the oblique cutting lines 4 are formed. When the tooth 1 is broken at the tip of the other side of the hook portion 2, the above-described principle of the present invention can be applied. However, when the tooth 1 closest to the hook portion 2 is broken When the saw blade 3 is detached by using the slant lines 4, the hooks 2 may be removed together.

Therefore, as shown in FIG. 5, the present invention is characterized in that one hooked portion 2 is formed so as to face diagonally opposite ends of a saw blade, or a pair of hooked portions 2 are formed at both ends of the saw blade 3, (2) is formed, when the sawtooth (1) close to the end of the sawtooth is damaged, the sawtooth is separated, the sawtooth is assembled to the hooked portion (2) on the opposite side and then the sawtooth of the damaged end is cut off. There is an advantage to be able to.
