Description

Technical Field

[0001] This utility model belongs to the field of saw blade technology, specifically relating to a multi-tooth saw blade. Background Technology

[0002] A saw blade is a tool used to cut materials, typically wood, metal, and other materials. Saw blades can come in different shapes and sizes to suit various cutting needs. Depending on the application, saw blades have different specifications regarding tooth pitch and tooth shape.

[0003] Existing saw blades have their tooth shape and structure directly molded onto the saw handle. To meet different usage needs, the entire saw blade needs to be disassembled and reassembled, which is not convenient. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-tooth saw blade, which has multiple tooth shapes, allowing for easier switching to meet different usage needs and providing flexible performance.

[0005] To achieve the above objectives, this utility model provides a multi-tooth saw blade, which includes a saw blade and a saw handle. The saw blade is connected to the saw handle, and the front end of the saw blade is provided with a first tooth shape. A first rotating shaft is provided on the upper surface of the saw blade, and a first rotating plate is connected to the first rotating shaft. The front end of the first rotating plate is provided with a second tooth shape.

[0006] The multi-tooth saw blade provided by this utility model can be flipped according to needs. After flipping, the front end of the saw blade changes from the first tooth shape to the second tooth shape, so as to meet different working requirements than the first tooth shape. When the first tooth shape is needed, the first rotating plate is flipped back onto the saw blade, so that the first tooth shape is exposed, and the first tooth shape is used for cutting.

[0007] In one possible implementation, a second rotating shaft is provided on the lower surface of the saw blade, and a second rotating plate is connected to the second rotating shaft. The front end of the second rotating plate is provided with a third-toothed saw blade. The addition of the third-toothed saw blade further improves the flexibility of the saw blade.

[0008] In one possible implementation, the length of the first rotating plate is greater than the distance between the first rotating shaft and the saw teeth of the first tooth profile, and the length of the second rotating plate is greater than the distance between the second rotating shaft and the saw teeth of the first tooth profile. The setting position of the first rotating shaft and the lengths of the first and second rotating plates affect the overall cutting depth of the saw blade on the object, and can be adjusted according to actual needs.

[0009] In one possible implementation, the first rotating plate and the second rotating plate are provided with a first fixing hole, and the saw blade is provided with a second fixing hole symmetrical to the first fixing hole at a position with the first rotating axis and the second rotating axis as the axis of symmetry. Fixing bolts are driven into the first fixing hole and the second fixing hole to fix the first rotating plate and the second rotating plate.

[0010] In one possible implementation, the first tooth profile has triangular teeth, the second tooth profile has large and small teeth, and the third tooth profile has wavy teeth. These three different tooth profiles are used to address different application requirements. Attached Figure Description

[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0014] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0015] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0016] See attached diagram. Figure 1 and Figure 2 As shown in the figure, the multi-tooth saw blade provided by this utility model includes a saw blade 1 and a saw handle 2. The saw blade 1 is connected to the saw handle 2. The front end of the saw blade 1 is provided with a first tooth shape. A first rotating shaft 31 is provided on the upper surface of the saw blade 1. A first rotating plate 41 is connected to the first rotating shaft 31. The front end of the first rotating plate 41 is provided with a second tooth shape.

[0017] The multi-tooth saw blade provided by this utility model can be flipped according to the needs of the first rotating plate 41. After flipping, the front end of the saw blade 1 changes from the first tooth shape to the second tooth shape, so as to meet the different working requirements of the first tooth shape. When the first tooth shape is needed, the first rotating plate 41 is flipped back onto the saw blade 1, so that the first tooth shape is exposed, and the first tooth shape is used for cutting.
