Description

Technical Field

[0001] This utility model relates to the field of woodworking electric saw technology, specifically a miniature dust-free inverted saw that can be rotated and adjusted. Background Technology

[0002] Existing rotatable and adjustable dust-free inverted chainsaws have the chainsaw main unit and the dust extraction fan mounted on the same side of the mounting base, side by side. The chainsaw main unit is connected to the mounting base via two side corner plates, one of which serves as a pivot point. Both side corner plates are also located on the same side of the mounting base. To ensure sufficient installation and rotation space for the chainsaw main unit, while also accommodating the installation of the dust extraction fan, the mounting base needs to be wide enough. That is, after the side corner plate on the pivot point side is installed, there still needs to be enough width to install the dust extraction fan's air chamber. Therefore, the overall width of the mounting base needs to be at least greater than the sum of the width of the chainsaw main unit and its two side corner plates plus the width of the dust extraction fan's air chamber to ensure sufficient installation space. This results in a large space and weight occupied by the entire inverted chainsaw body, making it inconvenient to assemble and carry. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing products and provide a rotatable and adjustable miniature dust-free inverted saw, solving the technical problems of existing dust-free inverted saws having large mounting base size, large space occupation, large weight, and high cost.

[0004] The technical solution adopted in this utility model is:

[0005] A rotatable and adjustable miniature dust-free inverted saw includes a mounting base for mounting an inverted saw main unit and a dust extraction fan. The inverted saw main unit and the dust extraction fan are located on the same side of the mounting base. The inverted saw main unit is rotatably connected to the mounting base via two side corner plates, one of which is a pivot side corner plate located on the pivot point side, and the other is a distal side corner plate located on the same side of the inverted saw main unit and connected to an arc-shaped groove provided at the edge of the mounting base via an adjusting bolt. The pivot side corner plate extends from the side where the inverted saw main unit is located through the mounting base to the opposite side and is connected to the mounting base via a pivot shaft, and the pivot shaft is located within the projection range of the dust extraction fan's air chamber towards the mounting base. Correspondingly, the mounting base has a first hollow portion for the pivot side corner plate to pass through and provide rotation space.

[0006] The mounting base plate has side plates perpendicular to the main body of the base plate on both sides. The outer wall of the dust collector's air chamber passes through the side plate on the fan side. That is, the side plate on the fan side has a second hollow part for the air chamber to pass through, and an extension connection part extends from the main body of the mounting base plate toward the second hollow part to connect with the air chamber.

[0007] With the above structure, the pivot point of the rotatable inverted saw main unit is set within the projection range of the dust extraction fan chamber, which reduces the overall space occupied, thereby reducing the overall width and weight of the mounting base, shrinking the volume, reducing costs, facilitating the assembly and carrying of the whole machine, and improving portability.

[0012] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0013] like Figures 1-4 As shown in the figure, this embodiment describes a rotatable and adjustable miniature dust-free inverted saw, which includes a mounting base plate 1 for mounting an inverted saw main unit 2 and a dust extraction fan 3. The inverted saw main unit 2 and the dust extraction fan 3 are located on the same side of the mounting base plate 1. The inverted saw main unit 2 is rotatably connected to the mounting base plate 1 through two side corner plates, one of which is a pivot side corner plate 21 located on the pivot point side, and the other is a distal side corner plate 22. The distal side corner plate 22 is located on the same side of the inverted saw main unit 2 and is connected to the arc-shaped groove 11 provided at the edge of the mounting base plate 1 through an adjusting bolt 221. The main body of the pivot side corner plate 21 passes through the mounting base plate 1 from the side where the inverted saw main unit 2 is located to the opposite side and is connected to the mounting base plate 1 through a pivot shaft 211 (or a pivot bolt). The pivot shaft 211 is located within the projection range of the air chamber 31 of the dust extraction fan 3 towards the mounting base plate 1. Correspondingly, the mounting base plate 1 is provided with a first hollow portion 101 for the pivot side corner plate 21 to pass through and provide rotation space. By installing the fulcrum side corner plate 21 through the mounting base plate 1, the fulcrum shaft 211 and the fulcrum side corner plate can be located within the air chamber projection range, thereby bringing the inverted saw main unit and the dust extraction fan closer together and reducing the distance. This will not affect the installation and operation of the dust extraction fan. In this way, the overall width and weight of the mounting base plate can be reduced, thereby reducing the overall space occupied and the weight of the whole machine, making it more convenient to assemble and carry.

[0014] The mounting base plate 1 has side plates 12 perpendicular to the main body of the base plate on both sides. The outer wall of the air chamber 31 of the dust collector 3 passes through the side plate 12 on the fan side. That is, the side plate 12 on the fan side has a second hollow portion 121 for the air chamber 31 to pass through, and an extension connecting portion 13 extends from the main body of the mounting base plate 1 toward the second hollow portion 121 and connects to the air chamber 31. Through the design of the second hollow portion 121 and the extension connecting portion 13, the width and weight of the mounting base plate 1 can be further reduced, further reducing the overall space and weight of the machine and saving costs.

[0015] In summary, by adopting the above structure, the pivot point of the rotatable inverted saw main unit is set within the projection range of the dust extraction fan chamber, which reduces the overall space occupied, thereby reducing the overall width and weight of the mounting base, shrinking the volume, reducing costs, facilitating the assembly and carrying of the whole machine, and improving portability.
