Due to the movement of the slide structure, the second telescoping transmission member rotates, and the third rod member and the fourth rod member slide relative to each other, and the fourth rod member rotationally moves the second rod member; The first telescoping transmission member rotates, and the first rod member and the second rod member slide relative to each other, and the rotation of the first telescoping transmission member causes the second sliding structure to move away from the opening 11. , when the door cover 2 is further pulled to open the opening 11 and the movable member 3 is pushed into the cover member 1, the movable member 3 moves the fourth slide structure in a direction away from the opening 11. , the movement of the fourth slide structure rotates the second telescoping transmission member, and the third rod member and the fourth rod member slide relative to each other, so that the fourth rod member rotates the second rod member. the first telescoping transmission member rotates, and the fourth rod member rotates the second rod member, and the rotation of the first telescoping transmission member causes the second sliding structure to move toward the opening 11. and further pull the entire door cover 2 to the one end where the opening 11 is provided in the covering member 1.

As shown in FIG. 1, in the first case of the third embodiment of the transmission mechanism, the first slide through groove 100 is provided above the second slide through groove 300, and the opening 11 of the covering member 1 is located at the front of the covering member 1. When the movable member 3 is pulled out of the covering member 1, the second lap joint 31 of the movable member 3 pushes the first lap joint 21 of the door cover 2, thereby moving the door cover 2 upward. At the same time, the second slide base 400 moves in the direction of the opening 11 along the second slide through groove 300 together with the moving member 3, and the second slide base 400 moves toward the opening 11 along the second slide through groove 300. The rod 42 is moved and rotated by the second slide base 400, and the second transmission rod 42 also rotates the first transmission rod 41 via the sixth slide structure 421 and the fifth slide structure 411 as the second transmission rod 42 rotates. The first slide base 200 is moved along the first slide through groove 100 from the direction approaching the opening 11 to the direction away from the opening 11, and the door cover 2 is further pulled to close the opening. 11 is opened and the movable member 3 is similarly pushed into the covering member 1, the second slide base 400 moves along the second slide through groove 300 together with the movable member 3 in a direction away from the opening 11. The second transmission rod 42 moves the first slide base 200 through the sixth slide structure 421 and the fifth slide structure 411 so that the first transmission rod 41 also rotates as the second transmission rod 42 rotates. The first slide through groove 100 is moved along the first slide through groove from the direction away from the opening 11 toward the opening 11, and the door cover 2 is also moved in the direction toward the opening 11, so that the first slide through groove 100 is moved toward the opening 11. Since the door cover 2 is provided above the second slide penetration groove 300 and is rotatably connected to the first slide base 200, when the entire door cover 2 moves to one end where the opening 11 is provided in the covering member 1, the door cover 2 can close the opening 11 by its own weight.
The moving process of the other case in the third embodiment of the transmission mechanism is the same as described above, and redundant explanation will be omitted here.

As shown in FIG. 11, in the second embodiment of the transmission assembly, when the movable member 3 is pulled out of the cover member 1, the second lap joint 31 of the movable member 3 is connected to the first lap joint 21 of the door cover 2. By pressing , the door cover 2 is turned upward and gradually moved away from the opening 11 of the covering member 1, and the movable member 3 pulls the connecting string 8, and the connecting string 8 pulls the door cover 2 and moves it away from the opening 11. is opened, the door cover 2 inverts to the top of the covering member 1 and moves backward, further compressing the spring 10, and when the force with which the movable member 3 is drawn out of the covering member 1 disappears or gradually decreases. , the spring 10 can push the entire door cover 2 toward the opening 11 of the covering member 1.
