This creation is about an operating device that can choose to disassemble and assemble the front wheel bearings of a locomotive either electrically or manually.

At present, the common steering mechanism of the general locomotive faucet is mainly a steering device installed in the front of the locomotive. The steering rod of the steering device passes through the head tube of the frame unit to connect to the front fork, so as to be able to be opposed to the head tube. Turn the steering lever. For example, the patent case No. M507889 "Locomotive Steering Device" announced by the Republic of China on September 1, 104. It is disclosed that the steering device includes a steering rod passing through the head tube, an upper bead bowl set in the lower end of the head tube, a lower bead bowl set on the steering rod, and a lower bead bowl set on the steering rod.

The upper and lower ends of the steering rod of the previous patent are respectively combined with a set of upper and lower ball bowls and steel ball units, so that the steering rod can be rotated smoothly and effortlessly. When the upper bead bowl is installed, it is fixed in the head tube by a strong force to prevent it from loosening and falling off. Because the locomotive is subjected to vibrations generated by the road slope during long-term riding, the steel ball unit hits the inner walls of the upper and lower bead bowls, and dents are generated, so that when the axial rod is rotated, the steel ball unit will be caused. Affected by the dents, the steering is not smooth, so the entire set of ball bowl bearings (upper ball bowl, lower ball bowl and steel ball unit) must be replaced. Since the upper bead bowl is fixed in the head tube, it is not easy to take out during disassembly and replacement, which may cause troubles in maintenance.
