[0050] In this embodiment: the T-block 801 is inserted into the T-slot 803 until the positioning block 804 is inserted into the positioning slot 802 under the elastic force of the first spring 805, and the fixed tooth plate 6 is positioned. Then, when the mounting plate 704 moves into the mounting slot 701, the extrusion block 809 contacts the mounting slot 701, and the extrusion block 809 is displaced by force. The extrusion block 809 is displaced by force, and the displacement of the extrusion block 809 pushes the reinforcement block 807 to move, causing the second spring 808 to be squeezed. The reinforcement block 807 is displaced into the slide slot 806 and contacts the positioning block 804, thereby fixing the positioning block 804.

[0051] Please refer to Figures 7 to 10 A second threaded hole is provided on the outer wall of the movable frame 902, and the second threaded hole matches the second threaded rod 903. A first gear tooth is provided on the outer wall of the connecting seat 910, and the first gear tooth is meshed with the fifth bevel gear 911. A second gear tooth is provided on the outer wall of the fixed side plate 906, and the second gear tooth is meshed with the third spur gear 913. The clamping plate 916 is tightly rotatably connected with the rotating bin 909, and the inner wall of the clamping groove 922 is in contact with the outer wall of the clamping block 919.

[0052] In this embodiment: the operation of the motor 904 drives the second threaded rod 903 to rotate, and the rotation of the second threaded rod 903 drives the movable frame 902 to move. When the movable frame 902 moves, it drives the third spur gear 913 to contact the fixed side plate 906, and the third spur gear 913 moves along the fixed side plate 906 to rotate. The rotation of the third spur gear 913 drives the rotating shaft 914 to rotate, and the rotation of the rotating shaft 914 drives the rotating rod 908 to rotate. At the same time, the fifth bevel gear 911 rotates along the outer wall of the connecting seat 910, thereby driving the fifth bevel gear 911 to rotate, and the rotation of the fifth bevel gear 911 drives the installation shaft 912 to rotate, and the rotation of the installation shaft 912 drives the rotating bin 909 to rotate, thereby driving the rotating bin 909 and the rotating rod 908 to rotate half a circle at the same time.
