Description

Technical Field

[0001] This utility model relates to the field of geared motor technology, specifically a geared motor that can be quickly disassembled. Background Technology

[0002] A quick-disassembly geared motor is a specially designed geared motor, mostly assembled from a motor and a reduction gear.
