[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] The present application provides a portable calculator, which is mainly used to solve the problem that the calculator may be scratched during use. Due to long-term use, excessive scratches may cause large scratches on the calculator display screen, which may damage the user's observation line of sight and bring inconvenience to the user. The following technical solutions are provided. Figure 1-Figure 3 Make a detailed description:

[0019] like Figure 1-3As shown, a portable calculator includes a calculator body, a protective shell is arranged outside the calculator body, a sliding groove is constructed inside the protective shell, a sliding plate is arranged inside the sliding groove, the sliding plate can slide in the length direction of the sliding groove, a slider is arranged outside the sliding plate, the sliders are divided into two groups and are fixedly installed on both sides of the sliding plate, the sliders are slidably connected to the sliding groove, the sliding plate can slide along the length direction of the sliding groove relying on the slider, and also includes a fixing component, the fixing component includes a first magnetic block and a second magnetic block, the first magnetic block is fixedly installed on the top of the protective shell, the second magnetic block is fixedly installed on one side of the sliding plate, the first magnetic block and the second magnetic block are arranged opposite to each other, the first magnetic block and the second magnetic block can attract each other, and also includes a carrying device, the carrying device includes a fixing block and a carrying rope, the fixing block is fixedly installed on one side of the protective shell, the two ends of the carrying rope pass through the fixing block and are fixedly connected with the fixing block, and the protective shell is provided with anti-slip patterns, anti-slip patterns, etc. The distance is installed on both sides of the outer wall of the protective shell, the protective shell is set to a flexible material, and the four corners of the protective shell are transitioned by arcs. In some embodiments, when the calculator body needs to be used again, the first magnetic block and the second magnetic block can be separated from each other, and then the sliding plate can be pulled out of the sliding groove, so that the calculator body is exposed and can be used.
