Description

TECHNICAL FIELD

[0001] The utility model relates to calculator technical field especially relates to a bill data increase and decrease calculator. BACKGROUND

[0002] In the modern business and financial field, the management and data processing of bills (such as invoices, receipts, checks, etc.) is an important and complex work. With the expansion of enterprise scale and the increase of transaction volume, manual processing of bill data is prone to low efficiency, high error rate and other problems. With the development of modern economy and the expansion of enterprise scale, bill processing has become an indispensable part of financial management. Traditional bill data processing methods often rely on manual input and calculation, which is not only inefficient, but also prone to errors. In addition, with the popularity of electronic bills, the amount of bill data has increased dramatically, and traditional manual processing methods have been difficult to meet the needs of modern financial management.

[0003] During use, the calculator is relatively light and needs to be carried around for use, and the keys need to be pressed frequently during use, so the base is needed to stabilize the calculator, otherwise the calculator will move due to frequent pressing, and the user cannot press the corresponding numbers quickly and accurately, resulting in errors. SUMMARY

[0004] The bottom of the calculator is designed with a non-slip pad, which can effectively increase the friction between the calculator and the desktop to prevent movement. When the user quickly inputs data or frequently presses the keys, the calculator can remain stable and avoid affecting the operation efficiency due to sliding. The bottom of the rubber base is provided with a non-slip groove, and the two sides are provided with suction cups. The non-slip groove further increases the friction between the bottom and the desktop, and the suction cups temporarily fix the rubber base and the calculator on the desktop through adsorption, providing additional stability. In this way, the calculator can be temporarily and stably placed on the desktop for use, and will not move when pressed frequently. The user can press the corresponding numbers quickly and accurately, thereby quickly calculating the data on the bill. When it is necessary to quickly process bills or other financial data, the stable calculator can improve the accuracy and speed of calculation, and reduce input errors or repeated operations caused by device sliding.

[0005] The first aspect of the present disclosure provides a bill data increase and decrease calculator, specifically comprising: a rubber base; the bottom of the rubber base is uniformly provided with a non-slip groove; the two ends of the rubber base are respectively fixedly provided with a stabilizing block, and the middle of the stabilizing block is provided with a through threaded hole; the two ends of the two stabilizing blocks are respectively fixedly provided with a side ear plate, and the lower end of the side ear plate is fixedly provided with a suction cup.

[0006] The middle part of the upper end of the rubber base is provided with a calculator, and a small cover is arranged on the front end of the calculator.

[0007] In at least some embodiments, a stable groove is arranged in the middle part of the upper end of the rubber base, and parallel guide grooves are arranged in the two ends of the rubber base.

[0008] In at least some embodiments, a threaded hole is arranged in each of the two stable blocks, and a threaded rod is arranged in each of the threaded holes.

[0009] In at least some embodiments, a bearing ring is arranged on the end of each of the two threaded rods, and a clamping plate is arranged on the outer ring of each of the two bearing rings.

[0010] In at least some embodiments, a limiting frame is arranged on the edge of each of the two clamping plates, and a guide block is arranged on the bottom of each of the two clamping plates.

[0011] In at least some embodiments, a display screen is arranged on the rear end of the upper end of the calculator, a number key is arranged on the left end of the upper end of the calculator, and an operator symbol key is arranged on the right end of the upper end of the calculator.

[0012] The bill data increasing and decreasing calculator has the following advantages:

[0013] In the calculator, the bottom of the calculator is provided with an anti-skid pad, which can effectively increase the friction between the calculator and the desktop to prevent movement, and the calculator can remain stable when the user quickly inputs data or frequently presses the keys, thereby avoiding affecting the operation efficiency due to sliding. The bottom of the rubber base is provided with an anti-skid groove, and the two sides are provided with suction cups. The anti-skid groove further increases the friction between the bottom and the desktop, and the suction cups temporarily fix the rubber base and the calculator on the desktop through adsorption, thereby providing additional stability. In this way, the calculator can be temporarily and stably placed on the desktop for use, and will not move when frequently pressed. The user can quickly and accurately press on the corresponding number, thereby quickly calculating the data on the bill. When it is necessary to quickly process bills or other financial data, the stable calculator can improve the accuracy and speed of calculation, and reduce input errors or repeated operations caused by equipment sliding.

[0014] The anti-skid pad at the bottom of the calculator also has an anti-skid effect, and the calculator will not easily move when being frequently pressed, thereby stabilizing the calculator, so that the calculator can quickly calculate the data on the bill. The anti-skid pad can effectively increase the friction between the calculator and the table, so that the calculator will not easily slide or shift even if the keys are frequently pressed during use. This stability ensures that the user will not make errors when inputting data due to movement of the device. BRIEF DESCRIPTION OF DRAWINGS
