Abstract
A protector for preventing motor damage is revealed. The protector includes a link member linked to a driving part of a motor and having a mounting groove and a first insertion hole, an elastic damping member that is placed in the mounting groove and disposed with a second insertion hole, and a driver member arranged with a projecting block and used for driving a passive member. One surface of the driver member is covered on the mounting groove to form a receiving space. The projecting block is mounted in the second insertion hole whose inner edge is closely attached to an outer edge of the projecting block. The damping member is compressed in the receiving space so that an outer edge thereof is tightly attached to an inner edge of the mounting groove and the driver member. Thereby the motor operates normally no matter the passive member is locked.
