DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings:

[0022] See attached Figure 1 and 2 As shown: This embodiment discloses an electric cutting knife adopting a new type of protective structure, including: a frame body 1, a driving motor 2 and a blade 4, the driving motor 2 is installed on the frame body 1, and a rotating shaft 3 extends outward from the driving motor 2, and the rotating shaft 3 is arranged outside the frame body 1; the blade 4 is installed on the extended rotating shaft 3, and the blade 4 performs rotating shearing through the peripheral shearing blade; the electric cutting knife in this embodiment also includes a blade guard 7 located at the rear end of the blade 4 and spaced from the blade 4, and the blade guard 7 is used to shield the shearing blade of the blade 4 to prevent the high-speed rotating shearing blade from being exposed to the outside, causing danger to the operator or accidentally touching the cut fabric and the power cord.

[0023] Furthermore, in order to facilitate the distribution of the cloth after cutting by the cutting knife, the present embodiment also includes a dividing portion 8 located on the blade guard portion 7 and higher than the outer plane of the blade 4, so that when the cloth moves after cutting by the blade 4, the cloth is separated to the outside under the action of the protruding dividing portion 8, thereby avoiding the cloth after cutting being clamped and stacked together to affect the cutting of the cloth; preferably, in order to facilitate guiding the cloth to be distributed outward, the outer end surface of the dividing portion 8 in the present embodiment can be an inclined guiding surface 8-1 that extends gradually outward from front to back.

[0024] like Figure 3 As shown, further, in this embodiment, the blade guard portion 7 is connected to a fixing portion 7-1 installed on the frame body 1, and an extension portion 7-3 is connected between the fixing portion 7-1 and the blade guard portion 7; specifically, the blade guard portion 7 can be formed by bending the extension portion 7-3 toward one side of the blade 4, and in order to facilitate the installation of the dividing portion 8, the dividing portion 8 and the blade guard portion 7 can be integrated.

[0025] like Figure 3 and 4As shown, the frame body 1 in this embodiment also includes a base 5 for support; correspondingly, a support portion 7-4 extending downward is provided on the fixing portion 7-1, and a seat plate 7-5 is provided at the lower end of the support portion 7-4, and the seat plate 7-5 is fixedly connected to the base 5; in this embodiment, the blade guard portion 7 is installed on the frame body 1 through the fixing portion 7-1, and then the base 5 is correspondingly installed and connected through the support portion 7-4 and the seat plate 7-5. Specifically, the seat plate 7-5 is arranged corresponding to the lower end surface of the base 5, and the support portion 7-4 is arranged through the base 5 so that the seat plate 7-5 located at the lower end of the support portion 7-4 is located at the lower end of the base 5 and corresponds to the lower end surface of the base 5, and screw holes are correspondingly opened on the seat plate 7-5 and the base 5, and the seat plate 7-5 is correspondingly fixedly connected to the base 5 by screws.

[0026] like Figure 2 As shown, specifically, in order to further increase the coverage and shielding of the blade 4, a groove 9 for installing the blade 4 is provided on the outer end surface of the frame body 1 in this embodiment. The groove 9 is a circular groove arranged corresponding to the rotation space of the blade 4, and the blade 4 is sunken and installed in the groove 9, so that the blade guard 7 on the periphery of the blade 4 is arranged in an arc structure and connected to the periphery of the groove 9, so that the blade guard 7 covers and shields the blade 4 along the groove 9, so that most of the shearing edge areas of the blade 4 except the cutting position are shielded, thereby avoiding accidental injury to the operator by the rotating blade 4;

[0027] Further, such as Figure 1 and 2 As shown, a protective cover 6 covering the outside of the blade 4 is also installed on the frame body 1 to further shield the position above the blade 4;

[0028] Further, such as Figure 2As shown, in order to ensure that the blade guard part 7 is accurately positioned during installation, so that the blade guard part 7 is connected to the outer periphery of the groove 9, in this embodiment, a sunken positioning groove 11 for accommodating the fixing part 7-1 and the extension part 7-3 is opened on the groove 9, and a channel hole 12 for accommodating the motor rotating shaft 3 is opened on the fixing part 7-1. The blade 4 is located outside the fixing part 7-1 and is fixedly connected to the motor rotating shaft 3 passing through the channel hole 12; specifically, the sunken positioning groove 11 includes a positioning circular groove 11-1 concentrically arranged with the motor rotating shaft 3 and a connecting groove 11-2 located at the rear end of the positioning circular groove 11-1 and connected to the positioning circular groove 11-1 for accommodating the extension part 7-3. In this embodiment, the fixing part 7-1, the blade guard part 7, the extension part 7-3, the support part 7-4 and the seat plate 7-5 are integrated. At the same time, the outer periphery of the fixing portion 7-1 is a circular structure corresponding to the positioning circular groove 11-1, and the structure of the extension portion 7-3 is corresponding to the connecting groove 11-2; and then during installation, the fixing portion 7-1 is installed in the positioning circular groove 11-1 and the extension portion 7-3 is installed in the connecting groove 11-2. Since the groove 9 is concentrically arranged with the rotating shaft 3, when the fixing portion 7-1 is correspondingly installed in the positioning circular groove 11-1, the fixing portion 7-1 is also concentrically arranged with the rotating shaft 3, and then the blade guard portion 7 which is connected to the fixing portion 7-1 through the extension portion 7-3 in an arc structure is also concentrically arranged with the groove 9. Finally, through the corresponding installation of the extension portion 7-3 and the connecting groove 11-2, the blade guard portion 7 is correspondingly located at a position connected to the outer periphery of the groove 9, thereby ensuring that the installation position of the blade guard portion 7 is accurate.

[0029] When cutting less stacked fabrics, the fabrics can be separated to both sides more easily after cutting due to the less stacked fabrics. However, when cutting thicker stacked fabrics, the fabrics cannot be separated to both sides spontaneously due to the heavy weight of the stacked multi-layer fabrics. Figure 3 As shown, in this embodiment, a thin material passing space 13 is provided between the blade guard portion 7 and the base 5. Therefore, when the electric cutting knife in this embodiment is used to cut a small amount of cloth, the cloth can directly enter the thin material passing space 13 after cutting without passing through the material dividing portion 8, thereby reducing the friction obstruction of the cloth by the material dividing portion 8, and facilitating the smooth cutting of thin materials.

[0030] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
