The case forms an inversion space. The inverting mechanism has an inverting base and multiple adapting modules. The inverting base is pivotally mounted in the inversion space. The adapting modules are mounted on the inverting base. Each of the adapting modules has an adapting port. The inverting base is capable of inverting to make the adapting port face downward and cover the inversion space. Dental handpieces can be mounted on the adapting modules. The control system has a control module and an operation input terminal. The operation input terminal is electrically connected to the control module and is capable of controlling the control module to inject a working fluid with pressure into the dental handpiece via the adapting module. ## Claims ### Claim 1 An inversion maintenance device for dental handpieces;
