A bottom mounting plate is located below the middle mounting plate, and a hanging rod is threadedly connected to the surface of the bottom mounting plate, with a nut at the top of the hanging rod. A display screen panel for indicating gear adjustment is fixedly installed on the outer side of the main frame, and detachable equipment components are housed inside the main frame. This application utilizes the main frame design and the screw mounting plate at the top of the main frame, with screws securing the mounting plate to the guide. This allows the equipment components to be installed inside the main frame, creating a structural relationship between the main frame and the equipment. The main frame supports the equipment components, facilitating both indoor and outdoor use. The installation method is simpler, and it facilitates the assembly and disassembly of the equipment, offering greater flexibility.
