The invention discloses a trackless electric retractable door. The retractable door comprises a work box, a support block is fixedly connected to the left end face of the work box, a work space of which one lower end wall is communicated with external space is formed in the work box, a linkage space of which one lower end wall is communicated with the work space is formed in the upper end wall ofthe work space, a movement groove of which one right end wall is communicated with the linkage space is formed in the upper end wall of the linkage space, a torque groove is formed in the support block, and an axial groove of which one front end wall is communicated with the external space is formed in the front end wall of the torque groove. The trackless electric retractable door is simple in structure and convenient to operate, the damage caused by objects such as stones on the movement path of the retractable door to movement of the retractable door can be eliminated, and therefore the trackless electric retractable door has a certain stabilization function; during closing of the retractable door, if large objects or people are located at the middle of the closing path of the retractable door, the retractable door cannot be closed and then automatically opens, and dangerous accidents are prevented from occurring.
