An electric and mechanical stretching apparatus for a movable sofa consists of a mechanical stretching apparatus and an electric apparatus. An electric connection rod (8) is disposed on the mechanical stretching apparatus. The electric apparatus consists of a motor (6), a motor connection pipe (2), a motor movement slide block (5), and a motor head fixing element (7). The motor (6) is a guide rail motor. The motor movement slide block (5) is mounted on a guide rail of the motor (6). A motor head is rotationally connected to the motor head fixing element (7) fixed on the electric connection rod (8) by means of a second rotating shaft (4). The motor connection pipe (2) is rotationally connected to the motor movement slide block (5) by means of a first rotating shaft (1). The motor connection pipe (2) is fixed on the mechanical stretching apparatus. The motor connection pipe (2) is fixed on a linkage element (3) of the mechanical stretching apparatus. The first rotating shaft (1) and the second rotating shaft (4) are both bolts. The electric and mechanical stretching apparatus for a movable sofa changes a conventional electric driving mode, which helps to improve the mounting, dismantling, maintaining and operating efficiencies of the electric apparatus for the movable sofa, and improve the automatic degree and the comfort of the sofa. |
