The dust cleaning component comprises an industrial fan, a mobile test plate, a fixed pipe, a dust blowing pipe and a connecting hose. A fixed pipe is fixedly installed on the bottom of the mobile test plate. The friction test bench for an orthodontic appliance can blow dust off the arch wire before the friction force test is performed on the arch wire, so that most of the dust on the arch wire can be effectively removed, and the arch wire can be prevented from being affected by dust and other foreign objects, resulting in inaccurate test data, thereby effectively improving the accuracy of the device during detection and improving the detection effect of the device.

[0004] The deficiency of the above-mentioned prior art is that the arch wire is first straightened, and then the hydraulic rod is controlled to start, which drives the mobile platform to move, and the movement of the mobile platform drives the friction force detector to move, and then the friction force detector is moved to perform the friction force detection of the arch wire. This increases the steps of arch wire friction force detection, and the detection is more cumbersome. For this reason, the present application proposes an oral orthodontic appliance friction test bench. Summary of the invention
