Detailed Embodiments

[0016] As Figure 1 shown, it is the state where the chain of the crane mechanism is retracted. Start the driving motor 202, and through the meshing transmission of the motor gear 204 and the gear 206 on one set of the rotating shaft devices 205, at the same time, the gears 206 on the two sets of rotating shaft devices 205 also mesh and drive, and drive the two sprockets 207 to rotate at the same speed.

[0017] As Figure 3As shown, the front sprocket 207 rotates clockwise, and the rear sprocket 207 rotates counterclockwise. Through the symmetrical rotation of the sprockets 207, the two groups of special chain structures 301 for window openers are driven to move downward through the front guide plate 104 and the rear guide plate 105. The rolled-up state above the two chain structures 301 begins to open, and the upper end of the chain structure 301 pulls the front winding shaft 402 to rotate clockwise, while pulling the rear winding shaft 402 to rotate counterclockwise through the upper end of the chain structure 301.

[0018] As Figure 2 shown, at this time, the front winding shaft 402 is pulled by the coil spring B405 to wind up the coil spring 403 clockwise, generating an elastic pre-tightening force. At the same time, the rear winding shaft 402 is pulled by the coil spring B405 to wind up the coil spring 403 counterclockwise, generating an elastic pre-tightening force.

[0019] As Figure 1 shown, after the goods are hung under the chain structure 301, the drive motor 202 is started. The motor gear 204 meshes with the gear 206 on one set of rotating shaft devices 205 for transmission. At the same time, the gears 206 on the two sets of rotating shaft devices 205 also mesh with each other for transmission, and drive the two sprockets 207 to rotate at the same speed.

[0020] As Figure 3 shown, the front sprocket 207 rotates counterclockwise, and the rear sprocket 207 rotates clockwise. Through the symmetrical rotation of the sprockets 207, the two groups of chain structures 301 are driven to move upward through the front guide plate 104 and the rear guide plate 105. The upper part of the two chain structures 301 begins to roll up through the pre-tightening force of the coil spring 403.
