[0035] Finally, the user can separate the locking screw 203 from the housing 1. At this time, the slider seat 202 can be pushed to move along the central axis direction of the guide slot 201 until the slider seat 202 is adjusted to a suitable position, so that the slider seat 202 can effectively clamp the installation position and fix the micro motor with bolts.

This is the working principle of the noise reduction micro motor with a wiring harness protection structure for household appliances.
