Description

Technical Field

[0001] The present invention relates to the field of maintenance devices, and in particular to a maintenance device for maintaining a payment terminal. Background Art

[0002] Mobile payment terminal refers to a service method for making account payments for consumed goods or services. Units or individuals send payment instructions directly or indirectly to banking financial institutions through mobile devices, the Internet or proximity sensors to generate monetary payments and fund transfers, thereby realizing mobile payment functions. Mobile payment integrates terminal devices, the Internet, application providers and financial institutions to provide users with financial services such as monetary payment and payment, and payment terminals are devices used to realize mobile payment functions.

[0003] At present, payment terminals generally require disassembly of the casing and internal components during maintenance. However, the existing maintenance workbench is relatively simple and is not suitable for the work of positioning the equipment and classifying, storing and conveniently accessing small items during payment terminal maintenance. Problems such as displacement and shaking of the equipment during maintenance make disassembly and assembly more difficult. Small parts removed during the maintenance process are often accidentally lost due to their small size, which has an adverse effect on the smooth progress of subsequent maintenance and assembly work. Maintenance personnel will set up storage boxes for collection, but it is more troublesome to take small parts out of the storage boxes. Summary of the Invention
