[0021] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0022] like Figures 1 to 3As shown, the blade of the electric hot knife is usually fixed in a single structure, that is, a pressing plate 202 and a knife seat 201 are only suitable for one blade 203, for example: Figure 1 Suitable for fastening straight blades; Figure 2 Suitable for fastening sculpture blades; Figure 3 It is suitable for fastening wire cutting knives; however, during operation, when using an electric hot knife with a straight blade, if the straight blade needs to be replaced with a sculpture blade or a wire cutting knife, the electric hot knife needs to be directly replaced, or the bolt and the pressure plate or the knife holder needs to be replaced to make the electric hot knife suitable for other types of blades; thus, the working efficiency is low and the cost is high.

[0023] like Figures 4 to 7 As shown, this embodiment provides a multifunctional blade fastening device for an electric hot knife, comprising: a blade holder 201, a pressing plate 202 and a blade 203. The pressing plate 202 is arranged on the blade holder 201. The pressing plate 202 and / or the blade holder 201 located between the pressing plate 202 and the blade holder 201 are respectively provided with a transverse mounting groove and a longitudinal notch 205. The fixed end of the blade 203 is fastened to the transverse mounting groove or the longitudinal notch 205. That is, by providing the transverse mounting groove and the longitudinal notch, the fastening and installation of blades of different models can be simultaneously met, the purpose of multi-function is achieved, and the efficiency of replacing blades of different models is improved and the tool cost is reduced; when replacing the blade, it is only necessary to separate the pressing plate 202 from the blade holder 201 by a certain distance, and there is no need to completely remove the pressing plate 202.
