Description

Saw for cutting wood

Technical Field

The utility model relates to the technical field of cutting, in particular to a saw for cutting wood.

Background

When cutting timber, stick or trees, need use the saw, current such saw does not have the saw frame, and is comparatively thin, and intensity is not fine, and the sawtooth of saw is seen from the side, divides into the interval setting, and left side is right side, and whole saw thickness is fixed, and the purpose of doing so is that the chip removal can be more smooth and easy. However, the saw teeth with the structure which are inclined left and right are not easy to process, and the cutting angle of the whole saw is not easy to control when the saw is used. And after the saw is used for a long time, the saw is likely to be clamped after the saw teeth are worn, and the resistance born by the saw is relatively large when the saw is pulled back and forth, so that the working efficiency is relatively low.

Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings.

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In the description of the present utility model, unless otherwise specified and defined, it should be noted that the terms "mounted," "connected," and "coupled" are to be construed broadly, and may be, for example, mechanical or electrical, or may be in communication with each other between two elements, directly or indirectly through intermediaries, as would be understood by those skilled in the art, in view of the specific meaning of the terms described above.

As shown in fig. 1 to 3, the present application provides a saw for cutting wood, comprising an operation section 1 and a connection section 2, wherein the operation section 1 comprises a saw body 3 and a saw tooth set 4, the saw tooth set 4 is arranged on one side of the saw body 3, and at least two connection holes 10 are formed in the connection section 2, so that the saw can be connected with a handle. A hanging hole 11 is arranged on the side of the saw body 3 far away from the connecting section 2, and the saw can be hung on a wall when not in use.

The width of the saw body 3 on the side close to the connecting section 2 is larger than that on the side far away from the connecting section 2, so that the weight of the whole saw can be lightened under the condition of not changing the strength, and the shape is attractive. The saw body 3 is provided with the blade 12 at the side far away from the saw tooth group 4, so that the saw can be used reversely when the saw needs to be cut by a knife, and the saw is convenient.

The sawtooth group 4 comprises a plurality of first sawteeth 5 and second sawteeth 6, the depths of the first sawteeth 5 and the second sawteeth 6 are different, and the first sawteeth 5 and the second sawteeth 6 can be one higher or one lower, so that the saw can be more labor-saving when being pulled to and fro, and sawn scraps can be discharged.

The first and second serrations 5, 6 are located in a line when seen from the side of the connecting section 2 towards the operating section 1, corresponding to the first and second serrations 5, 6 being not split to both sides when seen from the side of the serration set 4. The thickness of the operating section 1 gradually decreases from the tooth root of the sawtooth group 4 to the tooth body, namely, the width L1 of the operating section 1 at the tooth root is larger than the width L2 at the position far away from the tooth root, and the change from L1 to L2 gradually decreases, as shown in fig. 3. The width of the entire gap is then the tooth root width of the saw tooth, so that when the saw body 3 gradually enters the sawn gap, the entire tooth body can move in the sawn gap without being caught by the gap, since the width of the saw body 3 gradually decreases from the tooth root.

The first saw tooth 5 comprises a first section 7, a second section 8 and a third section 9, wherein an included angle between the first section 7 and the second section 8 is an acute angle, and an included angle between the second section 8 and the third section 9 is an obtuse angle, as shown in fig. 2. The included angle of the tooth tip of the second saw tooth 6 is 30 degrees to 50 degrees, preferably 45 degrees, so that the chip removal is easy when the second saw tooth moves back and forth. The first saw teeth 5 and the second saw teeth 6 are different in depth.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
