1. An electric winder, comprising:
a winder body, comprising:
a first housing;
a reel arranged in the first housing;
a drive mechanism connected to the reel; and
a cable wound on the reel;

a socket, comprising:
a second housing;
an insertion hole provided on a side of the second housing;
a contact assembly provided in the insertion hole; and
a strain sensor arranged in the second housing and attached to the contact assembly; and

a controller, configured to control on/off of the drive mechanism;
wherein the second housing is arranged outside the first housing, and the contact assembly is connected to a free end of the cable; the controller is connected to the strain sensor; when a plug is inserted into the contact assembly through the insertion hole, the strain sensor is configured to detect a deformation of the contact assembly caused by the plug, and send the deformation to the controller; and
the controller is configured to receive the deformation sent from the strain sensor; and when the deformation is greater than a deformation threshold, the controller controls the drive mechanism to be in a stop state to prevent the reel from winding.
