[0006] Therefore, the purpose of the present invention is to provide a saw blade that can reduce cutting resistance, thereby solving the problem that the existing saw blade is usually stuck inside the saw seam when cutting wood, so the user needs to expend a lot of physical strength to pull it out.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] A saw blade that can reduce cutting resistance includes a saw blade body, the lower surface of the saw blade body is fixedly connected to a first metal plate, a second metal plate and a third metal plate in sequence, the lower end of the first metal plate is fixedly connected to a plurality of first saw teeth, the lower surface of the second metal plate is fixedly connected to a plurality of second saw teeth, and the lower surface of the third metal plate is fixedly connected to a plurality of third saw teeth, and each of the first saw teeth, the second saw teeth and each of the third saw teeth are staggered.

[0009] Preferably, one end of each of the first saw teeth is inclined inwards.

[0010] Preferably, one end of each of the third saw teeth is inclined outwards.

[0011] Preferably, one side of the first metal plate and the third metal plate is provided with an inclined surface.

[0012] Preferably, the widths of the first metal plate, the second metal plate and the third metal plate are greater than the width of the saw blade body.

[0013] Preferably, mounting holes are provided at both ends of the saw blade body.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model prevents each first saw tooth, second saw tooth and third saw tooth from fitting into the inner part of the saw groove at the same time by staggered arrangement between each first saw tooth, second saw tooth and third saw tooth, thereby reducing the contact area and thus reducing the cutting resistance.

[0016] 2. The utility model tilts each first saw tooth and each second saw tooth to both sides respectively, so that the overall width of the first saw tooth, the second saw tooth and the third saw tooth is greater than the overall width of the first metal plate, the second metal plate and the third metal plate, thereby increasing the width of the saw groove and preventing the first metal plate and the third metal plate from rubbing against the saw groove.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the utility model discloses a saw blade capable of reducing cutting resistance.

[0025] The utility model provides Figure 1-3 A saw blade that can reduce cutting resistance is shown, including a saw blade body 1, the lower surface of the saw blade body 1 is fixedly connected with a first metal plate 2, a second metal plate 3 and a third metal plate 4 in sequence, the lower end of the first metal plate 2 is fixedly connected with a plurality of first saw teeth 5, the lower surface of the second metal plate 3 is fixedly connected with a plurality of second saw teeth 6, and the lower surface of the third metal plate 4 is fixedly connected with a plurality of third saw teeth 7, and each first saw tooth 5, second saw tooth 6 and each third saw tooth 7 are staggered.

[0026] The staggered arrangement of each first saw tooth 5, second saw tooth 6 and third saw tooth 7 can prevent each first saw tooth 5, second saw tooth 6 and third saw tooth 7 from fitting into the inside of the saw groove at the same time, thereby reducing the contact area and thus reducing the cutting resistance.

[0027] In order to make the overall width of the first sawtooth 5, the second sawtooth 6 and the third sawtooth 7 greater than the overall width of the first metal plate 2, the second metal plate 3 and the third metal plate 4, as shown in FIG. Figure 1-3 As shown, one end of each first saw tooth 5 is inclined inward, and one end of each third saw tooth 7 is inclined outward.

[0028] Each first saw tooth 5 and each third saw tooth 7 is tilted to both sides respectively, so that the overall width of the first saw tooth 5, the second saw tooth 6 and the third saw tooth 7 is greater than the overall width of the first metal plate 2, the second metal plate 3 and the third metal plate 4, so as to increase the width of the saw groove and prevent the first metal plate 2 and the third metal plate 4 from rubbing against the saw groove.

[0029] In order to prevent the saw blade body 1 from rubbing against the saw groove, Figure 2 As shown, one side of the first metal plate 2 and the third metal plate 4 are both provided with an inclined surface, and the width of the first metal plate 2 , the second metal plate 3 and the third metal plate 4 is greater than the width of the saw blade body 1 .

[0030] Because one side of the first metal plate 2 and the third metal plate 4 is provided with a bevel, the width of the first metal plate 2, the second metal plate 3 and the third metal plate 4 is greater than the width of the saw blade body 1 to prevent large friction between the saw blade body 1 and the saw groove.

[0031] In order to facilitate the installation of the saw blade body 1, as Figure 1 As shown, mounting holes are provided at both ends of the saw blade body 1 .

[0032] The two mounting holes can facilitate the installation of the saw blade body 1 .

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
