[ 4. An electromechanical stretching apparatus of a convertible sofa, consisting of a mechanical stretching apparatus and an electric actuator, the mechanical stretching apparatus comprising an electrically-driven connecting rod,
wherein the electric actuator consists of:
a motor comprising a motor head and a guide rail,
a motor connecting tube connected to the mechanical stretching apparatus and the guide rail,
a motor movable slider installed on the guide rail of the motor, and
a motor head fixing part fastened on the electrically-driven connecting rod, and
wherein the motor head of the motor is rotationally and removably connected through a second rotor shaft to the motor head fixing part fastened on the electrically driven connecting rod;
wherein the motor connecting tube is rotationally and removably connected to the motor movable slider through a first rotor shaft;
wherein the motor connecting tube is fastened on the mechanical stretching apparatus via at least two connections between one end of the motor connecting tube and the mechanical stretching apparatus;
wherein the motor connecting tube extends to one end side at the one end of the motor connecting tube, the end side is fastened on a linkage part of the mechanical stretching apparatus via the at least two connections, the end side is substantially parallel to the linkage part, and the linkage part is not directly connected with the electrically-driven connecting rod; and
wherein the first rotor shaft and the second rotor shaft are both bolts, and a bolt connection of the motor is achieved by a rotational connection of the first rotor shaft and a bolt connection of the second rotor shaft. ]
